The scale just isn't there. A single nuclear power plant near me, McGuire Nuclear Power Plant, produced 17,514 GW·h in 2005. The entire potential output of the Tesla (cough Panasonic) Gigafactories in California and China have a combined output of ~50 GWh per year. [0] Nuclear power is amazing at producing a reliable base load of power that massively outstrips our ability to produce and store solar power. Say our load is well aligned with the cycle of solar power and we're ignoring weather so we can derate the amount we want to store to 30% that's 105 years of production out of what I think is the two largest batter plants in existence to store the power produced continuously by a single large nuclear power plant.

I don't follow your sums. 50GWh of battery cycled once a day for a year is: 18,250 GWh

So you seem out by around 100x.

Global stationary storage deployed for 2024 will be ~150GWh, and this is accelerating. Batteries are easy, nuclear appears to be impossible (economically speaking).

[rtkwe]

So 35 years then to store the power generated 24/7 by McGuire at that rate of production which ignores that the huge spike of AI loads will want 24/7 power, if we're looking at that kind of load I'd rate it at 50% for starters (low to be honest because it doesn't account for how solar ramps up during the day) which is around 60 years. Plus that's giving full capacity to those batteries when ideally we'd only use the middle 60% to avoid deep cycling the batteries daily unless they've completely solved that problem.

The nuclear ain't getting built, these are facts. Even if one breaks ground today, you won't push your first kwh to the grid for a decade, at which point another ~10TW of clean energy will have come online globally.

If AI is using too much power in the short term, destroy demand with policy and economics. We are not beholden to the robot trainers, we just don't provide utility access to the load. Unlimited demand of industrial scales of electrical power isn't a right of some sort.

What other activities are prohibited in your dream dictatorship?

[toomuchtodo]

Everyone is a libertarian until it’s their commons experiencing the tragedy. Strange to think that having regulations around large scale electrical loads is a dictatorship. It’s okay for us to collectively say no, depending on the circumstances.

> Everyone is a libertarian until it’s their commons experiencing the tragedy.

Yeah sure and everyone is a socialist utopian until its their own money/liberty on the line.

If we cannot “collectively” reach a consensus what happens?

Im just pointing out that the original suggestion of “ban ML for environmental reasons” is extreme/ham-fisted. This is what dictatorships do in real life all over the globe “for the greater good”.

Should crypto be a government-approved use of energy? What about manufacturing semiconductors? Building data centers? Producing EVs, solar farms or batteries? Are flights for vacation allowed?

You aren’t thinking about the second order impact of having a government that has the ability to gatekeep energy production for specific use cases…

1.2gw of storage means in 4hr it's gone if solar and wind are weak

[ben_w]

And can be recharged as soon as the wind or the sun comes back.

The sizing of batteries and power sources is highly region specific, and the places where it makes sense today with current manufacturing capacity, don't have to be "everywhere" for it to be fine where it's actually done; and given the roll out rate of renewables, we also don't need to wait until battery output per year can totally displace the existing and currently running gas plants, just back up the newly installed renewables themselves - 4h in this case is how fast the PV farm would recharge those batteries in the best case, the average output of a PV plant is about 10% of the peak, so this is really a 40 hour battery pack not a 4 hour pack.

[Moldoteck]

I mean, look at Germany's grid yesterday& today and tell me, with such overcapacity, how much more overcapacity it would need and how much storage it would need to cover such events with low wind and solar?
