Experience
Research
When does a climate patent become clean power on the grid? I built a 30 year panel to measure the lag, and the clearest signal so far shows up in solar.
If the renewable share had stayed at its 2000 level of 16.3%, power sector emissions across the panel would be 2,990 Mt higher in 2023 and 19,936 Mt higher cumulatively. Sources: OWID generation, EDGAR emissions.
