Comment It's to cash in on short term price spikes. (Score 4, Interesting) 41
I think it plausible that 99% of new energy this year come from renewable sources because many of those sources come from renewable types with relatively short construction times.
Up until recently, the US adds about 50 GW of capaicty per year. There's a huge uptick in generation capacity because of energy demands from data centers, so recently it's more like 65 GW/year. The challenge is you can't exploit *this year's* high market prices by starting a nuclear power plant that won't come on line for a decade. Even a combined cycle natural gas plant is going to take five years. But you can have a wind farm up and running in months.
It's not the renewability *per se* that's driving this; it's profiting from the high prices before the AI bubble bursts. Nobody is rushing to bring new hydropower or geothermal plants online, and they're just as renewable as wind or solar.
This move to renewables is not about changing the world. it's about short term financial optimization. But these short term, local optimizations *will* change the world, and planning to handle the transformations driven by short-term market forces is going to take coordinated, long term national action. At present there are regional mandates that will stabilize the local grid against variations in electricity supply. But carving up the nation into small regional markets means higher prices and economic inefficiencies where electricity is transfered from high price areas to stabilize low price areas. Market economics don't work if there are non-market forces (stability) that trump profitability.
