alt Hacker NewsThat is not correct, and doesn't even pass the sniff test. Solar is deployed at ~$2/watt and you're saying batteries are increasing that cost 2.5x to 10x? So, someone installing a home battery system is paying up to 10x their solar install cost to also have battery backup? No way.
Also, battery tech continues to improve rapidly, we're seeing breakthroughs like this rapidly reduce the price: https://spectrum.ieee.org/co2-battery-energy-storage

These are numbers from the known far-right organization....err... Fraunhofer Institute for Solar Energy: https://www.ise.fraunhofer.de/en/publications/studies/cost-o...

Exactly. And you need closer to 100x for some locations (Germany) for the solar to be reliable enough.
Solar is _very_ cheap when you don't care about reliability, and impossible otherwise. Wind is a bit more nuanced, but in general has a similar story.
As usual, explain how you're going to power heat pumps in the Northern half of the country during a 3 week bomb cyclone. There are answers and they cost money.
The only answer we're using is to build 1:1 natural gas capability for solar, which is roughly double the cost. That's a solution, but it needs to be accounted for when comparing options.
