The scaling up of battery manufacturing for EVs and now solar storage has lead to prices I would have never imagined I'd see in my lifetime. It's one of the success stories that, having lived through it, has been a real joy.
I know that folks might have been able to point to a graph years ago and said we'd be here eventually, but I had my doubts given the scale required and hacking through all the lobbying efforts we saw against solar/battery. Alas, we made it here!
Alas is right, China is poised to dominate battery, solar, and EV technology and to translate it to military technology as well. Meanwhile the Republicans are blowing up US alliances and sabotaging the battery/EV industrial development policy that was actually making progress in giving the US hope in catching up.
It’s the innovators dilemma. We have so much not just technical but cultural and political sunk cost in fossil fuels and traditional industrial era infrastructure. The Chinese are just developing now and don’t have so much of that sunk cost. So they can think like it’s the future. We are stuck in the past.
Eventually there may come a day when it’s China that is stuck in the past, looking back to the early 21st century like we look back to the middle twentieth, and someone else will be ascendant.
I really felt like Trump’s 2024 election was the moment it became the Chinese century. It was the moment we chose to exit our position of world leadership both culturally and technologically.
Chinese CCP are willing to scarifies whatever traditional industrial era infrastructure in order for things to move forward and gain a global advantage. Especially when they are not the one paying for the scarifies.
Just because a country has previously invested in fossil fuels, it doesn't follow that they can't get the benefit of solar with future investment. However, there's a lot of powerful money/people/corporations that depend on fossil fuels for making billions - that's the real problem as that skews the market and politics of energy production/distribution.
That political sunk cost is why the innovators dilemma happens. It happens in companies too where managers, executives, and top employees will have their careers built around a certain way of doing things. Change threatens that so they will resist change and double down.
Basically success creates the preconditions for this failure mode in the future.
It might be thought of as a form of overfitting. Success results in overfitting to a local maximum.
>I really felt like Trump’s 2024 election was the moment it became the Chinese century.
You must have been asleep at the wheel or living under a rock to have mised China's rise over the last decades. They didn't wait for Trump to get elected in 2024 and then flipped a switch from third world country to global superpower.
"Damn, this hot cup of coffee burned my tongue. Why would Trump do this?"
This is exactly right, IMHO. We were in a course to counter China's momentum, we had handled COVID so much better, our industry had a huuuuuuge investment in it and was poised to take tiff.
And then it was all killed. And we are killing off our other competitive edges over China, the way we attract all the world's best science and tech talent to build here in the US rather than in their own countries. We have sat back scientific research 2-5 years by drastically cutting grants in nonsensical ways and stopping and decimating a class of grad students.
We were the most admired country in the world, and in a short amount of time we have destroyed decades of hard work building a good reputation.
We won't get that back in a year or two, it's going to be decades of work.
It was that Trump and the MAGA crowd conceded to the Chinese by destroying US goodwill and credibility built up over decades. The US will probably never recover those advantages, just as China is ratcheting up its program of dominance. Trump et al have destroyed many things that made the US great.
It's bewildering why anyone would do such a thing but here we are.
Unlikely, since our labor costs are still considerably higher than elsewhere. For a very long time our economy has rested on developing high margin products and letting others do the low-marginal-overhead of making it. We assumed that they were not going to catch up to us as innovators.
That was a dangerous mistake, and we may be left with nothing.
Same here in Germany/Europe. Our conservatives actually destroyed the solar industry for the third time. Our conservative party has actually destroyed significantly more jobs in solar industries over the last 20 years than it keeps alive with subsidies of 70k€ - 100k€ per person working in that industry (direct and indirect subsidies make the 70 - 100k€ range).
But hey, our populist right tell us, that the subsidies for "green technology" are bad and that we need to get rid of them, because they are making energy so expensive in Germany (cleared of inflation energy costs are lower than 2013, 12 years ago).
But hey - people vote for those parties. Because they know their economics, not like the leftists, who don't.
Germany (or Europe in general) is fucked. In a few years, we will reap what we now sow. And not because of our social systems or immigration, but because our oh so great political leaders are not willing to invest in the future.
> cleared of inflation energy costs are lower than 2013, 12 years ago
This is not the argument you want to make. Energy prices are a significant component of the basket used to measure inflation. Like yeah, you expect energy prices to sink if you discount for the rise of energy prices. Germany is suffering from high energy prices its the key factor why the country has been stagnating economically for the past 6 years.
Their energy prices are an outcome of incompetence, having tied their energy prices to Russia and a gas supply from them. In hindsight, economic diplomacy is not the path to keeping an authoritarian in check; a strong military and energy independence is.
German energy prices will decline with battery storage and more renewables pushing out the last of their coal and fossil gas generation. Should’ve kept the old nuclear generators running too, as long as possible. Alas, a lesson they’ve learned.
When the iron curtain fell pretty much all of Central Europe liberalized and democratized. The sole exceptions being Belarus and Russia.
Thinking they wouldn’t choose the same path is revisionist.
I remember growing up and gaming online thinking of Russians as nothing strange compared to anyone else. This changed with first Georgia and then very much Crimea.
> cleared of inflation energy costs are lower than 2013, 12 years ago
Dude, soaring energy prices are driving inflation. That's like saying the prices are lower if you just keep ignoring everything that actually makes them more expensive. Duh.
I don’t care if German prices for electricity are below inflation. They’re just still expensive. As an EV owner is difficult to find an electricity provider with costs below 0,25€/kWh, and most of them go beyond 0,30€. While I had prices in other European countries for around 0,05€/kWh at night for example.
Not only that, Conservatives, Socialists and the Green all managed to increase our electricity CO2 footprint by moving from nuclear to coal/lng.
That’s mainly because German has fucked up the smart meter rollout. In their wisdom they separated the meter and the gateway when other countries just combined it. They also made it super secure (good), but then didn’t look at the fact that lots of people live in rented apartments and their meters in the cellars have really poor or no cellular connectivity. When Germany can finally do steerable dynamic loads properly at 95% of the market rather than under 10%, it will finally make a difference on steering pricing for such consumers as yourself.
Germany is investing in massive battery parks dotted around the grid. This will make a difference to supporting base load and offsetting coal, but it will take time.
If there’s anything about the Germans you can count on, is that they move slowly.
China is governed by the CCP, which holds the world record for the number of people murdered by the state, feeds its citizens militaristic propaganda at scale, is currently controlled by a guy who fancies himself a dictator, and is politically stable only as long as it continues to suppress free speech and free trade. It takes a dangerous kind of willful naivete to just ignore that fact.
This is oversimplified view of the world and China.
China being powerful is not something new, it was the world's largest economy for 18 of the past 20 centuries (with exceptions being parts of the 19th and 20th centuries, when Western Europe and then the US surged ahead after the industrial revolution).
> is politically stable only as long as it continues to suppress free speech and free trade.
Your analysis is through the lens of Western culture. The definition and understanding of freedom and harmony are entirely different in China. I was in China and experienced this myself, so this is firsthand experience, not something I picked up from blogs or news.
In the Chinese context, freedom is defined collectively so freedom from chaos, poverty, foreign domination etc, whereas here in the West it's individual liberty. Harmony and social stability are seen as more valuable than political pluralism, so authoritarian governance is culturally framed as legitimate. You know that 100 million Chinese travel abroad every year and all of them come back to China? Chinese leaders and citizens still remember periods of fragmentation and civil war.
There is a widespread belief that adopting a Western adversarial political model could reintroduce instability and weaken national unity so something China cannot risk given its size and diversity (you know how many ethnicities there are in China?)
This is their natural state. China has a long history of centralized, bureaucratic governance (over 2k years since the Qin Dynasty), where stability and order are prioritized.
Yeah. I have also been to China myself, and have first hand experience walking around Hong Kong with people who later found themselves in jail, or riding the subway getting bombarded with saturation level jingoistic propaganda urging attack against the capitalist aggressors, or getting a tour of Beijing from a friend who worked as a photojournalist and found himself followed by the security services and had to leave and seek asylum with his family.
The silent majority is silent, yes. Those who try to do something get pushed out, or worse. It's the double-edged sword of immigration. But the Chinese people love freedom like the rest of us - you don't need to go far to disprove your entire narrative, Taiwan and Singapore are right there.
I'm sick and tired of whataboutism from people who are somehow motivated to carry water for aggressive dictatorships that threaten the rest of us. I've already lost my birth country to zombies like that (they call them z-patriots, or turbopatriots, the supporters of Russia's invasion of Ukraine). In case you missed it, my original comment was intended as a criticism of the current government of the United States.
> Are you saying “alas for citizens of the US who see things in competitive nationalist terms”?
He’s saying it as a realist.
China is building the equivalent to America’s sanctions power in their battery dominance. In an electrified economy, shutting off battery and rare earths access isn’t as acutely calamitous as an oil embargo, but it’s similarly shocking as sanctions and tariffs.
Yes and no - yes it’s dumb to give up and let china have a defacto monopoly on the future of energy production. But no insofar as sanctions on battery and solar don’t hit the same as oil and other things. Because once you have them, they keep producing for you.
The change in Chinese output between 2023 and 2024 was an additional 15,000 tons, going from 255,000 to 270,000 tons. The USA's own increased by 3400, from 41,600 to 45,000 tons.
I'm happy to assume Brazilian output will grow, especially if the USA invests a lot in it, but is it going to even be close to enough to make up for where China's already at? China was about 70% of the global output.
For real. I think there's a type of American that would rather hype up the evils of china than admit the distance the US has fallen from its purported ideals. This year I've seen students deported for criticizing Israel, mobs of poorly trained militarized federal police roaming neighborhoods violently disappearing people without trial, the number of homeless grow to 700,000, food kitchens with lines around the block and a president straight up selling pardons to drug dealers.
Chinese totalitarianism just doesn't seem like such a huge contrast as it once did. At least they get an increase in quality of life for the tradeoff. Also a lot of this reeks of Sinophobia tbh
I'm in Berlin, I have more to fear from Trump's administration than from Xi Jinping's.
If I was in the Philippines, I think it would be the other way around. Initially I also had Japan and Taiwan in that comparison, but thinking a bit harder, there's also a risk that Trump is isolationist, that means the risk from each is more like a multiplier than a simple comparison.
You are certainly not alone in your beliefs, but it always amazes me which technologies get the benefit of doubt and which are severely penalized by unfounded doubt. Solar and especially batteries are completely penalized and doubted in a way that defies any honest assessment of reality. The EIA and IEA forecasts are as terrible as they are because the reflect this unrealistic doubt (random blog spam link, but this observation is so old that it's hard to find the higher quality initial graphs)
Similarly, nuclear power gets way too much benefit of the doubt, which should simply vanish after a small amount of due diligence on construction costs over its history. It's very complex, expensive, high labor, and has none of the traits that let it get cheaper as it scales.
10 new plants at USD 2.7 Billion each. They take six years to build. USD 2/Watt. They have standardised designs, have invested in grownig their manpower and know-how.
If you believe China's internal pricing numbers, sure....
But their actual investments in billions of dollars and in GW show that nuclear is not competing with solar, and is sticking around for hedging bets. They the are deploying far far far more solar and storage than nuclear. And if those nuclear costs were accurate, then nuclear would be far preferable. $2/W is incredible, as in perhaps not credible, but it would also be far cheaper than solar.
And even if China figured out how to build that cheaply, it doesn't mean that highly developed countries will be able to replicate that. Nuclear requires a huge amount of high skill, specialized labor, and doing that cheaply is only possible at certain levels of economic development. As economies develop to ever higher productivity, the cost of labor goes up, and it's likely that nuclear only ever makes sense at a very narrow band of economic development.
In addition to coming so far down in price, it's amazing to me how good the technology has gotten. Batteries that can easily discharge 5C in cold weather, cycle 10000 times, survive harsh conditions with zero maintenance. Panels that last for decades.
Which is why it makes me especially angry that the current US government is throwing away this gift in order to appease a bunch of aging leaders of petro-states. Literally poisoning the world for a 10-15 year giveaway to the richest of the rich.
I take some solace knowing that fossil fuels are now a dead end. And even though certain people are trying to keep the industry going, that end is sooner than ever.
In general it's obvious this is the trend & amazing.
It is a little surprising to me that some markets don't see the benefit. I was pretty delighted ~8 years ago to get some 4500mah 6s batteries RC (under 100Wh) for ~$65 but the price doesn't feel like it's changed much since, based on some light shopping around. Just wanted to note what I perceived as an unevenness. https://rcbattery.com/liperior-4500mah-6s-40c-22-2v-lipo-bat...
Too put the facts crudely, the world would be fucked climate change wise without China. The oft heard "why do anything while China is the problem" would be hilarious, if people repeating bald-faced bullshit didn't grate so much.
Of "control everything" and "execute anyone who disagrees", only the former is useful; the latter is kinda why Russia (and the USSR before it) are failing despite also having a government that could control everything.
You only achieve greatness when your control gets you to do the correct thing. Strong governments make decisions faster, not better. Freedom to debate, to speak out against bad governance, to speak truth to power, democracy, all that's a system to keep a government pointing in the right direction, it slows down decision making but (generally) also increases the accuracy of that decision making.
Same deal with free markets in capitalism: its a feedback mechanism, Tim Cook can announce the Vision Pro and Zuckerberg the Metaverse, direct their teams to spend whatever number of billions was necessary to develop them, market says no.
Batteries are probably going to kill long-range transmission lines and open up remote generation at a scale never thought possible. Desert solar, remote hydro, etc etc. As the price continues to fall and the density continues to rise the economics of transmission completely change and will decouple the location of power generation from the use of that power dramatically. This decoupling of location and use will drastically reshape energy production. Right now is likely the time to buy sunny land in the middle of nowhere but near train tracks.
I think long range transmission remains a thing anywhere having a local grid remains a thing (which will be most places for other reasons).
Load-balancing the area having a cloudy few days and the area having a sunny days and the area having a windy few days and so on will remain extremely valuable. It lets you install a lot less batteries and isn't that much infrastructure given that the last mile problems are dealt with already.
I get that, I'm just disagreeing that we should be looking forwards to storage becoming that cheap. Particularly when our cheap energy sources (solar, wind) have a lot of location specific variability over time.
With some exceptions for sufficiently remote (or sufficiently always-sunny and not too dense) places that local grids themselves are no longer worth it
The original report by Ember [1] is decent but clearly biased.
They assume each battery cycles entirely EVERY day - even in winter. They also assume PV is never curtailed - not even in summer. They of course ignore multi-day weather anomalies. Like wise for weekend/holiday demand variations. etc.
The best part of the report are real world bids of 2025 ESS projects.
I do look forward to local storage getting that cheap. If Standard Thermal (here I am hawking them again) succeeds, we could see local PV-generated seasonally stored 600 C heat at as little as $3/GJ -- competitive with Henry Hub natural gas.
I think there is a calculation that makes the point a little clearer. There is some distance, x, where it is cheaper to transport the electrons mechanically than it is to push them over a wire. Every month that distance gets shorter as battery prices drop. This gets even more advantageous for batteries when you start talking about variable use and generation since it is easier to change the destination or source of a battery container than it is to change the destination or source of transmission lines. My main point is that that distance x is going to rapidly get towards just a few miles away from point of use very shortly. Imagine a small city getting a local electricity provider. I actually think the way it is likely to go is that energy consumers (cities, factories, etc) will start installing backup power via battery shipment and then slowly start disconnecting from the larger grid as the cost of the battery container delivered power dips below the cost for transmission line delivered. The infrastructure is just so much more efficient for most use cases because we already have that infrastructure for shipping other goods.
> My main point is that that distance x is going to rapidly get towards just a few miles away from point of use very shortly.
That seems physically unlikely to me. Sure, burying and maintaining cables costs money, but other than that transferring energy in a very fundamental and solid state way is going to be much easier than packaging it up and transporting it with heavy machinery.
This is definitely a case where your argument only works if it is supported by the actual calculation.
Rail freight: $160 / ton per 1,000 miles. At 220 Wh/kg a ton of batteries is 200kWh. So rail costs $800 per MWh per 1,000 miles without considering the cost of the batteries themselves.
You probably don’t want to use regular batteries for that. I’d go with shipping energy as aluminum or something like that and use aluminum-air batteries. But regular hvdc seems really hard to beat with shipping of any kind.
> Batteries are probably going to kill long-range transmission lines and open up remote generation at a scale never thought possible.
Not at current power densities.
The bandwidth of a station wagon filled with hard drives is quite high; the power delivery of station wagon filled with batteries is on the low side compared to a wire made from the same material as that station wagon and buried under the road the wagon would have been driving along.
Even for liquid and gas fuels, people make dedicated pipelines rather than doing it all by truck and train.
Surely batteries will be used in conjunction with solar, and as solar is already distributed (except for high latitudes), the need for power distribution will diminish as once you're setup with solar and batteries, you only really need the transmission lines to sell any excess power. Presumably, once solar is rolled out at scale, there will be little demand for purchasing excess power.
Extreme case sometimes used to argue against PV is the Arctic circle. Anywhere in the Artctic circle has to choose between enough batteries to cope with entire days when the sun's below the horizon *or* a transmission line further south where the sun's still up.
Or a different renewable, or nuclear, my point here isn't any particular answer just that there's cases where you might go for something other than PV+battery, and my point before is just about yeeting batteries around.
That said, re-reading the comment I was originally responding too, I may have inferred too much from:
> Right now is likely the time to buy sunny land in the middle of nowhere but near train tracks.
And the previously quoted words "remote generation".
> Extreme case sometimes used to argue against PV is the Arctic circle. Anywhere in the Artctic circle has to choose between enough batteries to cope with entire days when the sun's below the horizon or a transmission line further south where the sun's still up.
I can imagine that they might go several months without usable sunlight, so yes, they'll likely need some form of energy distribution unless they plan on burning blubber for their energy needs.
All nice and beautiful, but I don't understand how will this work in the winter in the temperate areas. You maintain parallel natural gas installations and ramp them up in the winter? Does this doubles the cost?
Not having to burn gas is cheaper than burning gas. There will be a decade or two of transition with rarely used gas turbines getting their yearly packet in a short amount of time. Eventually other tech will take over, or the gas infrastructure will pare down and be cost optimized for its new role or rare usage.
Europe, and Germany and the UK in particular, are really poorly suited to take advantage of this new cheap technology. If these countries don't figure out alternatives, the countries with better and cheaper energy resources will take over energy intensive industries.
This is not a problem for solar and storage to solve, it's a problem that countries with poor resources need to solve if they want to compete in global industry.
Wind power. Mix with emergency reserves running on open cycle gas turbines, if deemed necessary, preferably running on with carbon neutral fuel. Optimize for lowest possible CAPEX.
That is contingent on that we’re not wasting money and opportunity cost that could have larger impact decarbonizing agriculture, construction, aviation, maritime shipping etc.
The next hot thing (pun intended) is geothermal. The tech to drill deep enough opens up the possibility of extracting geothermal energy in most of the world. The tech exists and is deployed. Scaling is not yet proven but is very plausible. Geothermal runs 24/7 and can be clean base load power.
It’s not just drilling deep enough, it’s whether they can keep the wells open and flowing long enough to make the whole thing economic.
Some deep geothermal projects have failed because the wells wouldn’t stay open. Maybe this generation of companies have solved this problem; let’s wait and see.
From a global perspective, people living in temperate areas are actually the exception, not the rule (if a disproportionately economically successful exception).
The likely implication of this is that, long term, unless wind power starts going back down the cost curve, or you're fortunate enough to have lots of hydro power, Northern Europe, Canada, northern China and so on are going to have much more expensive energy than more equatorial places.
This probably depends a lot on how close you are to the equator. Here in Germany output of solar in winter is negligible, and if there is no wind, which can happen for several consecutive weeks, we need a backup. No utilities company will build a fossil power plant that will be used only a few weeks per year, so our government will have to step in to make sure this happens.
On top of this you have very high costs for an increasingly complex grid, which needs to be built and then maintained. Prices will never again be as low as in the fossil/nuclear era.
Here are some numbers: January 2025, the output of solar was ~1500 GWh, it peaked in June at 10500 GWh. So the lowest output was about 15% of the maximum, this year.
Looking at wind, the ratio between min and max per week is about 1:5 (~1200 vs ~6000 GWh). Just as there is always some solar power generation, there is never no wind, though looking at those charts there were 4 weeks in the late summer of 2023 when production was low consecutively, between 700 and 1000 GWh.
How do you interpret these numbers? If your point is that we can simply overprovision photovoltaik arrays by a factor of 6.67, then that would make solar the most expensive power generation method by far.
And it only gets worse the more households transition to heatpumps, because the consumption in winter is so lopsided. For example, I heat my home with a heatpump, and I have 10 kWp of solar arrays on my roof. In the last week of July, we consumed 84 kWh and generated 230 kWh (273 %). In the last week of November, we consumed 341 khW and generated 40 kWh (11 %). This means we'd need roughly 10 times as much PV area to match demand (10 roofs?), and huge batteries because most of that consumption is in the evening, at night, and in the morning.
Of course, utility-scale and residential solar behave a bit differently, and it becomes more complicated if wind is factored in. But it shows that you can't just overprovision PV a little to fix the main problem of solar power: that it is most abundant in summer, and most in demand in winter.
My point was really only that neither is solar what I'd consider negligible in winter, nor are there really weeks with no wind. Other than that, my interpretation is pretty much the same as yours.
Above, I looked at the weekly min/max ratio. Of course the daily ratios are much higher, 1:60 for solar, and about 1:30 for wind. But wind and solar do have a useful anti-correlation: the ratio is "only" about 1:15 for combined solar+wind. Still high, but a huge improvement on both wind and solar individually.
In reality, the ratio is even higher since we routinely have to drop solar and turn off wind turbines when there is more production than demand (and I don't think that generation is reflected in the graph).
Ie. the max is already a representation more of grid and demand than of production, and it'd make more sense to use the ratio of min:mean, so comparing what we expect PV+wind to produce on average with what they give on the worst day. That gets us a different, more favorable ratio: 195 TWh produced in 2025 so far, let's call it 550 GWh/day, giving a ratio of about 1:6.
Thank you for actually running the numbers. I think the data is quite convincing that overprovisioning won't be the solution to the seasonal storage problem, or at least not the major factor in it.
Personally, I have high hopes for flow batteries. Increasing storage capacity is so easy with them, liquids can easily be stored for a long time, and it would even make long-distance transport by ship feasible. If only we can find a cheap, suitable electrolyte.
This is just a slighty more sophisticated version of the "solar doesn't work at night" trope.
The implications of bringing it up is that these silly hippies haven't even thought of this basic fact so how can we trust them with our energy system.
Meanwhile, actual energy experts have been aware of the concept of winter for at least a few years now.
If you want to critique their plans for dealing with it, you'd need to do more than point out the existence of winter as a gotcha.
I don't see you countering my argument, only attempting to ridicule it ("slighty more sophisticated", "trope", "these silly hippies", "been aware of the concept of winter", "existence of winter as a gotcha"). That sucks, man :-(
> If you want to critique their plans for dealing with it […]
There are many ideas for seasonal storage of PV-generated electricity, but so far there is no concrete plan that's both scalable to TWh levels and economically feasible. Here on HN, there's always someone who'll post the knee-jerk response of "just build more panels", without doing the simple and very obvious calculation that 5x to 10x overprovisioning would turn solar from one of the cheaper into the by far most expensive power generation method out there [1].
[1] Except for paying people to crank a generator by hand, although that might at least help with obesity rates.
And this also leaves out all the heating power still consumed directly from fossil fuels. The gap is much larger.
This doesn't have have to be by switching consumption; using less is possible: Passivhaus is from Germany, after all. However, you can't do that and keep all your historical protections on buildings and layers-upon-layers of red tape on renovations.
For reference, Germany has ~101GW of solar capacity installed as of this comment (and is deploying ~2GW/month). 59% of Germany's electricity in 2024 came from renewable sources, up from 56% in 2023. I am curious to see how 2025 turns out, and therefore predict 2026 from planned renewables and battery storage projects.
Possible things are to over provision solar, and set it up further south with a high voltage dc cable. We almost had a Morocco - UK power setup but the current government said no to it.
Nuclear plants, like most large thermal plants, are almost always located near large bodies of water and return that water downstream so it doesn't really matter?
It matters when the level of that body of water drops by a lot in summer and the water temperature rises at the same time. Add environmental laws (cooking the fish is discouraged), and your nuke plant needs to go into safety shutdown pretty reliably every summer.
Historically the biggest impediment to nuclear power has been incompetent construction management and project management. Incompetent is a strong word for it but nuclear power plants are the largest capital equipment purchases on the planet. Even modern so-called modular designs can't save poor project management, and learn as you go engineering.
That so mundane and should be easy to fix, right? That's why I bring up scale. Nobody has experience running projects that big. Some things are just too big to manage.
Does anyone know whether it makes sense to setup solar arrays closer to users or to concentrate them in sunny places and send them throughout the country?
e.g. an analysis of whether we should setup all the solar farms in Nevada for the whole country... set them up in the general south and transmit north... or will each state have their own farms?
Distributed. New transmission lines have big nimby issues, and many existing corridors are already getting overloaded. There are recurring attempts to reform the permitting process (in the last Congress it was called EPRA/energy permitting reform act), but… we’ll see.
Bureaucracy is the main thing holding back clean energy right now, rather than economics. You can see this in how Texas, which has lax grid regulation but isn’t biased towards clean energy has far surpassed CA, which subsidizes and got a big head start, in wind/solar generation in a few years.
We don't put all our coal and gas plants out in the desert, they're next to and within our cities.
Physically transporting electricity across distance is very expensive and a not-insignificant amount of power is simply lost on the way. These problems only get worse as the amount of power goes up, and the danger grows very quickly as power goes up. Plus the strategic and logistical benefits of distributed generation.
Simply put you can't centralize generation for the entire country. There's no practical way to actually transport that much power. Not with the technology we have today. If we had high-temperature superconductors then it would make more sense. But with standard metal wires, it's not happening.
In the GB (UK mainland) grid only ~2% of energy is lost in transmission; distribution is more typically ~5%. And we did put most of our big thermal power generation in the middle of the country, which is now causing difficulties as we need to re-jig transmission to accept offshore wind and interconnectors.
Solar PV on rooftops is great, injecting power directly at the load, eliminating transmission and distribution losses until there is excess to spill back to grid. It would be helpful if we stopped running an entirely artificial timetable in winter that demands heavy activity well outside daylight hours, so that demand better matched availability.
> Simply put you can't centralize generation for the entire country.
Depends on the country.
In Washington state, our power sources are not next to our population centers; in fact many are in the center of our state! And our state would be the 87th-biggest-country out of 197 in the world.
USA averages 6% transmission loss. New long-distance transmission lines are HVDC and have far less loss over distance. But people oppose them for dumb and good reasons; why would I in Washington state want to have good connections to California so the local producers can reduce supply and drive up prices?
Casey Handmer is a huge solar bull and his estimate is that solar becomes cheaper than any other form of electricity even when generated from northern states by 2030 (likely sooner)
Iirc solar is meaningfully more efficient (30-50%) in southern states, so it will likely make sense to place energy intensive workloads in locations with more direct sun.
However, the cost of transmitting additional power is interesting and complex. Building out the grid (which runs close to capacity by some metric^) is expensive: transmission lines, transformers or substations, and acquiring land is obvious stuff. Plus the overhead of administration which is significant.
So there's a lot of new behind-the-meter generation (ie electricity that never touches the grid)^^
With all that in mind, I expect energy intensive things will move south (if they have no other constraints. Eg cooling for data centers might be cheaper in northern climes. Some processing will make sense close to where materials are available)
But a significant amount of new solar will still be used in northern states because it's going to be extremely cheap to build additional capacity. Especially capacity that is behind-the-meter.
IMHO "efficient" isn't really the right term in your second para. The PV generation per W incoming is actually a little lower at higher ambient temperatures, but is otherwise fairly constant.
I assume that you mean higher kWh/y/kWp, ie you get more generation out of a given solar panel in the south each year.
If you would have a high voltage DC transmission line already, linking the dessert and the clouded cities far away, then it makes sense. I think it is worth building them, but it is a big investment. Many lines are proposed, some already build, but with the current US administration I don't think it is a priority.
High voltage transmission lines are really quite efficient, and concentrating generation is usually the right choice.
That said, it doesn't make sense to have just a single place for the entire country, as there are multiple grids in the US (primarily East, West, and Texas), and with very long transmission you can get into phase issues.
Concentrating generation made sense when transmission was cheap in comparison.
But one effect of ever cheaper solar is that transmission costs start to dominate generation costs, because transmission is not getting cheaper.
Cheap solar and storage requires rethinking every aspect and all conventional wisdom about the grid. Storage in particular is a massive game changer on a scale that few in the industry understand.
There are different LIPO chemistries. LFP in particular has little problem with being fully charged. You'll see it get swapped in for lead acid chemistries even in places like car/motorcycle batteries.
If you want an Lithium power supply then the keyword to look for is "LFP".
Lead Acid as far as I know is about $500 per KWh of usable space due to their depth of discharge being limited to about 50% and then they last about 3 to 5 years if they kept within their 500 cycles at most. Whereas a LiPho battery will last 10-15 years, 6000 cycles and costs about £120 a KWh. So I have no idea how UPS based on lead acid is ending up cheaper, its not based on the battery tech cheapness.
Sure, up front you're paying very little for that box that can run your PC for an hour.
But over 2-4 years you'll have to replace that UPS after it fails catastrophically in really dumb ways, and that's if you're lucky and it doesn't also burn your house down, whereas a proper storage system will last for a long, long time with more capability.
In my business I've never had a deskside UPS live longer than that.
And yes, we don't buy the ultra expensive ones. That's true.
Do not try this at home, but I replaced the lead acid battery in my UPS with a LFP battery. From what I read online, the charging curves for lead acid batteries and LFP batteries are very similar. The LFP batteries have a slightly higher charging voltage, so I expect my LFP battery to only charge upto about 80% capacity or so due to the charging voltage being slightly too low. I'm hoping the battery will last 10 years instead of 2 or 3 years.
Do not try this at home, as changing battery chemistry is quite ill advised.
Some of the power stations from Ecoflow/Anker/Bluetti are competitive in terms of price and capacity while still having a fast enough switchover for UPS purposes.
They tend to have features that may not be necessary for a UPS (eg solar or DC input), while lacking some features that are more common on UPS (eg companion app to turn your computer off when UPS gets low, although you might be able to rig your own solution)
Eaton and APC at least have models with LFP chemistry, with comparable prices across power ratings. The LFP will be more expensive though due to the increased longevity, at least until lead-acid ones stops being produced.
The acid in lead acid is sulfuric acid and if overcharged vents hydrogen gas, thats why they need a ventilated space typically. Sealed lead acid have safety vents that might pop if enough pressure builds.
They are most certainly not inert, they just have well established safety and charging protocols and are not used in very high quantities together because of their low energy density and cycle life.
LFP batteries which have iron phosphate cathodes are very stable compared to colbalt based batteries that tend to have catastrophic failures due to overcharge causing cathode failure. LFP have higher cycle life and are cheaper and typically whats used for storage and application where the loss in erergy density is not a big deal.
I live in Switzerland and my house currently consumes 35-40kWh of electricity each day. I'm in the process of installing as many panels as possible on my roof and right now in winter, they're forecasted to produce ~18kWh on a good day.
While it'll be possible for me to be more than fully self-sufficient in summer, I'd need roughly 3x more panels to come close to having a chance in winter, plus far more battery storage than is reasonable.
I suspect it might be more doable somewhere with milder winters, like Italy but especially as you go further north and the days get shorter, there's just no chance.
For it to work in places with large seasonal differences, we need something else (e.g. nuclear) and/or storage.
This doesn’t really capture their meaning though. They are describing a change in how the solar generated electricity can be treated due to the changing battery prices.
Arguably your edit is more factual. But part of the job of the title in an editorial like this is to tell you what their perspective is.
I assume the intended meaning is “reduced battery costs make around-the-clock solar-generated electricity possible”. I don't think it's possible to predict how technical changes in electricity production and storage impact prices.
Ember’s report outlines how falling battery capital expenditures and improved performance metrics have lowered the levelized cost of storage, making dispatchable solar a competitive, anytime electricity option globally.
Well they are two different words with two different meanings. Both are true in this case. “Available” in the sense “obtainable,” “ready for use,” “suitable for a purpose” or perhaps “available to investors”
Garden path sentence structure trap creation relies on initial word parse error encouragement. Brain pattern recognition system default subject-verb-object order preference exploitation causes early stop interpretation failure.
Solar battery costs plummet phrase acting as complex noun modifier group creates false sentence finish illusion. Real subject findings arrival delay forces mental backtrack restart necessity.
Noun adjunct modifier stack length excess impacts processing speed negatively. Back word function switch from direction noun to support verb finalizes reader confusion state.
We write to be understood. Short sentences and simple words make the truth easy to see.
Falling battery prices make storing solar electricity for later use economically viable. This means we can use electricity from solar anytime around the clock. Even accounting for the cost of batteries, it's still competitive with other sources of electricity.
To me the context string is just a bit...lumpy or something, I don't think it's directly about the grammar. I would have written something more like: a battery costs plummet, analasis finds "anytime electricity" is now available from solar.
It's already cheaper to demolish an existing coal plant that's already paid for and replace it with solar + battery. Solar and battery brand new buildout, plus their maintenance overhead, dominates coal even when you only count coal's maintenance cost.
People have it in their heads that this is some bleeding heart, don't ruin the planet thing, but it's plain economics. Non-renewable energy is simply inferior, and will only become more so.
> Non-renewable energy is simply inferior, and will only become more so.
you simply can't say this. despite the lobby against it, solar and wind energy have lifespans of around 20 years and afterwards, it's a freaking mess to deal with recycling and often times, garbage we don't know what to do. not even counting the amount of NASTY chemicals going into the production of solar panels. these are sometimes permanent and will have a great long term impact on ecology if we just start destroying plants to substitute with "green" alternatives mindlessly
one can also make a point that despite wind generators metals and batteries being almost to 100% recyclable, it's heck expensive to do and we don't have infrastructure. a comparison cosidering everything involved may show that hydroelectrics, nuclear, geo-thermal and heck even gas may have a similar or better impact depending on location
Its fair to do an accounting of externalities. However, I generally find those raising externality issues with solar and wind wildly overestimate their impact and wildly underestimate the externalities of fossil fuels. You mention the 20 year lifespan, this is a huge benefit compared to fossil fuels. The externalities of oil and gas add up for every second they are used.
Sure, and none of that amounts to even close to the damage from stripping vast areas of the earth to dig up coal, grinding and transporting it to power plants, then setting it on fire, and releasing tons of CO2, and then disposing of tons of unburnt waste full of NASTY chemicals.
And having to do all that continuously, every day, for the life of the plant.
In every single solution you can point out problems. Complaining that "X isn't perfect" is the easiest and laziest thing in the world to do. Assessing the ACTUAL costs and damages IN PROPORTION is more difficult, but actually yields good results.
It can be viewed as stripping vast areas of the earth, to put them in the shadow of a solar farm. That utterly disrupts the ecosystem underneath, though in a different way. That's usually hand-waved away.
If you actually read any of the reports of current research, you would find that combining solar with agriculture improves both the health of the flock and/or crops being produced, and increases output. More shade for the fauna, and better moisture profile for the flora, for starters.
Similar effects can also be created in currently wild areas that does NOT disrupt the ecosystem, but augments it. For starters, in very dry areas which are ideal for solar deployment, the typical constraint on the ecosystem is lack of shade and moisture preservation, which is mitigated by solar deployment
There are also VAST areas of already populated or in-use areas that are ripe for deployment of solar panels, rooftops, parking areas, canals, reservoirs, and more, and ALL of them are a net improvement with solar panels
So, nobody is stripping anything from the earth, and there is no continuous transportation of materials to set them on fire. The fact that it is already CHEAPER to produce electricity by tearing down a coal plant and installing the same solar capacity shows how crazy it is.
Just because something was the best way we had to do something three technology generations ago does not mean it is still best, or even viable or recommended. Stunning to see such unscientific backwards attitudes on a site focused on science and technology.

no one here typed that photovoltaics shouldn't be on play. but the way it's being paraphrase, feels like a panacea. the OP telling other skeptical opinions against mass substitution to photovoltaics is 'a shame on a tech oriented forum' probably don't even know that regulations and deals of these ballparks have a bunch of regulamentations and considerations that even needs to look for the security/reliability of the grid agaisnt (cyber)terrorism and war...
they then bring a cute little article of people producing tomatoes under laboratory settings being shaded by solar panels. we are chatting about mass production and distribution of energy. if you think it's economically viable to dismantle coal stations and substitute them for solar only shows ignorancy from a multitude of fields... as if energy was easy as comparing output of CO2/$ per watt produced! they even were ironic agaisnt (underdeveloped yet more sane than photovoltaics in the long-term for a vast majority of cases) nuclear technology :D we may shall dismiss the discussion of hooking up batteries on wind/solar, as current prices don't make recycling (batteries) any sense in a large scale that will be decentralized due the geo-location of wind/solar requirements. or do you think transporting these batteries to be recycled in specific areas is just a matter of building cargo-drones powered by solar energy and AI vision? we may also dismiss ecology on the amount of area and damaged species by exchanging any power plant to wind/solar because it's cheap. even group of populations agaisnt visual pollution coming from wind turbines, for example. we also should dismiss the amount of thrash burried by thousands and thousands of multi kilo tons wind turbines after 25 years etc. /s
Nice, a lovely screed using exactly the same Fear, Uncertainty, and Doubt techniques used by tobacco companies to promote cigarettes for decades after they were proven to be the source of mass fatal diseases costing people and society, and again reused by the fossil energy companies.
Every single claim above is at best massively outdated and/or outright wrong and disproved (and no, I won't go do your research for you and find cites for everything).
So, start from the bottom:
>> thrash burried .. multi kilo tons wind turbines
not sure if you mean buried or burned, but wind turbines are already being recycled and reused in bulk, and that is ramping up (and also offtopic from solar)
>> visual pollution coming from wind turbines
Again offtopic, and also purely a matter of taste; it doesn't affect anything
>> transporting these batteries to be recycled in specific areas is just a matter of building cargo-drones powered by solar energy and AI vision
Nice strawman argument from something I never said, and no, there are plenty of other perfectly good transport methods. And yes, recycling batteries is already becoming good business and a great feedstock for 'mining' the materials, and no it does not need to be a big deal, and siting the 'mining' facilities for recycling/recovery is vastly more flexible than siting mining for coal which is obviously necessary wherever the coal happened to form 100 million years ago.
>> they even were ironic agaisnt nuclear technology
Again, a strawman argument, as I never said I was against nuclear tech, and I am in fact for the new forms of nuclear tech, particularly the smaller even portable reactors ('tho the promise of Thorium reactors seems to have faded, but I'm not sure why).
>> if you think it's economically viable to dismantle coal stations and substitute them for solar
Again, only citing multiple studies showing that, and again, you entirely miss the point, which is not that you'd necessarily do it in every case, but that the point of coal being even the economical option has long passed, nevermind the environmental catastrophe it creates.
>> cute little article of people producing tomatoes under laboratory settings
tomatoes aren't the only thing being produced in conjunction with solar panels, and there are so many projects and studies showing its effectiveness in both improving results for farmers and improving their financial stability that it has a name: "agrivoltaics". Instead of spending your energy scoffing at things you obviously know nothing about, perhaps go read up on it and learn something.
>> security/reliability of the grid agaisnt (cyber)terrorism and war
If you want security and reliability, the best thing is widely dispersed power generation as close as possible to the use location. I have advocated for decades that a DOD project like the US Interstate Highway System should be done to ensure every household had a minimum amount of solar self-generation capacity, and stockpile transformers which have a manufacturing lead time of years. A nationwide grid outage without this is a potentially civilization-collapsing event, whereas if every household had some baseline capacity, they can still refrigerate food and communicate. Obviously just a cutout example, but the principle of diversity of power sources and locations makes a more robust system. Only bad grid planning makes solar or wind anything other than an improvement in grid reliability.
Moreover, battery tech is now sufficiently cheap that even the net cost of installing solar+batteries is lower than fossil plants, and that combination has better stability and millisecond-response rates that massively stabilize the grid (vs. ramp-up times measured in minutes-hours for gas plants and days for coal/nuclear).
>>a shame on a tech oriented forum
It is not the discussion of other options, but the disproportionate dismissal and spurious arguments that is a shame here. I'm sure there might be some exceptional situation where a new coal plant might actually be better all things considered, and if you have an actual example to discuss then bring some fats, but overall, that ship has sailed.
with agrivoataiagain, there are hundreds of article
Who cares if we never figure out how to recycle them? bury them in a landfill, and we’ll still be so far ahead on the pollution front than any other alternative. This is such a non issue
i'm not defending coal. i'm just saying that solution to energy is much more broad than the OP seems to pass on "being cheaper to destroy a coal plant and substitute with batteries and solar". i wouldn't be surprised trey sightread titles and didn't realized that it may be economical to re-use an OLD coal plant to produce solar energy but well... my last comment on this thread has it all, great book
then you can move on and judge what't the panorama of closed/paywalled science found out there (Nature) that evaluates impacts of solar panel not even considering numbers of last batches of thrash from ~ 2010 (which still have 10-15 years till they start filling the world with chemicals like lead)... then may dive into electricity security and distribution and recycling technology to bring up a single ignorant phrase comment downsizing nuclear generation, despite it being safer and ecological on the long-term compared to photovoltaics in LOTS of places, for example
Fuel cost for gas/coal can be rounded to $2/MWH - so then you need to amortize the cost of the plant over all the energy produced and you get to roughly 2x fuel cost for nat gas plants and 3x - 5x for coal ones. See page 10 here for sensitivity to fuel costs though;
$100+ meh for natural gas. Solar and battery is so cheap that arab countries are now building large solar and battery systems to save money instead of burning oil and gas. Where as in the US the other big oil and gas producer wholesale electricity prices for Natural Gas is around $100-150 mwh which is cheaper than coal and the major reason coal got pushed out. Then we have China and India where coal is around $40-50 mwh.
So solar and batteries are now cheaper than all other forms of energy/electricity the only problem is finance for poor countries as you need to spend for all the 15-20 years of electricity in one go where as for coal and gas you will spend the same amount over 10-15 years. For rich countries the problem is mostly protectionism as cheap energy would destroy a lot of wealth of people in power.
I know that folks might have been able to point to a graph years ago and said we'd be here eventually, but I had my doubts given the scale required and hacking through all the lobbying efforts we saw against solar/battery. Alas, we made it here!
