>Solar is so much more useful close to where it's consumed, like rooftops and parking lots. Utility-scale solar power projects like this are just more corporate welfare boondoggles.

What is more efficient, a utility with dedicated engineers and technicians who spend their days managing an install or clueless homeowners who can’t even be bothered to clear the leaves off their panels?

Installation and management for large scale commercial companies is _much_ cheaper. Bespoke rooftop installs require way more permit, engineer, contractor overhead. Oh year and don’t forget to upgrade your roof framing and hope your installer doesn’t ruin your waterproof membrane of your roof. Have a clay tile roof? There’s another 5k in broken roof tiles.

Transmission losses are in the noise by comparison.

And when your components go out… a small potato install can basically go pound sand. A friend of mine has been out 18 months b/c LG Chem recalled his battery and hasn’t replaced it! They remotely disabled it, so it can’t be used.

Contrast that with a utility. LG chem would probably have a dedicated field agent to manage bad batteries for a utility scale buyer.

>Deserts have fragile, intricate ecosystems. This fucks them up. We need to learn to stop fucking things up to gobble up more energy.

You know what’s worse for desert eco systems than solar installs? Climate change. Gobbling up 25% of the deserts to prevent the other 75% from becoming totally uninhabitable sounds like a bargain to me.

We need more solar as soon as possible. Messing up the desert to save the artic and permafrost is a winning bet every time.

Even when you need to transport it thousands of miles? Thats where most people are in relation to the deserts in the US.

The tradeoffs:

1. we already have a grid

2. the US southwest is where the sun is. insolation per unit of area is crazy high compared to elsewhere, meaning you need less panels per unit of generating capacity.

2.5% loss per 1000km.

1.45$/w for commercial install

2.95$/w for residential install.

That doesn’t include management economies of scale.

Big chunks of the US can’t do solar in the winter, so you need long range transmission anyway.

As a point of reference, it is about 4000 km from LA to New York. Assuming a linear drop-off (probably not true, but close enough), you would only lose 10% crossing the country.

Solar panels might be decreasing in cost 10% annually, so over-building to accommodate that seems entirely feasible.
