Life as we know it isn’t possible without electricity but fossil-fuel-generated electricity is threatening the planet’s climate and our future. Therefore, as I laid out in Part 1 of this series, the first prong of our six-pronged strategy for addressing climate change is to get almost all electricity from net-zero sources by 2050. That goal is certainly formidable. Zero-carbon sources, mostly in the form of solar power, wind power, nuclear power, and hydropower, currently account for about 37% of all electricity generation. Getting those net-zero sources close to 100% by 2050 would eliminate 27% of the current problem for carbon emissions. (The table…
