The resources needed to build much less maintain these at scale is a disaster, one that's largely inflicted on 'not us' but that requires massive economic transfers through globalization. You're not building these at this scale without globalization.
- 41% wind
- 36% solar
- 19% gas
- 4% other
I was actually kind of pleasantly surprised. 28 GW capacity added, 8.5 GW capacity retired.
Total capacity 1115.68 GW generated summer 2020
Total breakdown 2021 is more like this:
- 36% Petroleum
- 32% Natural gas
- 11% Coal
- 8% Nuclear
- 12% Renewable energy

There've in fact been several notable decommissionings of hydro projects, and extant geothermal (such as The Geysers in northern California) are producing well below their peak due to field exhaustion (various factors, typically groundwater and/or actual thermal flux).
Wind and solar have grown markedly, but remain a small fraction of total electrical generation. Which itself remains a fraction (roughly 1/3) of total energy consumption.
