In 2021, developers and power plant owners plan to bring 39.7 gigawatts (GW) of new electricity generating capacity on line, and retire 9.1 GW in generating capacity, for a net increase in capacity of 30.6 GW, according to the EIA today. 70% of the capacity additions will be from wind and solar, 16% will be from natural gas, and 3% will be from a nuclear reactor. These are utility-scale power generators and exclude rooftop solar. Of the retirements, 86% will be coal and nuclear.
Electricity generation in the US has been a no-growth business since 2006, as efficiencies in electrical equipment (LED lights, appliances, air conditioning, etc.) and further offshoring of manufacturing have kept consumption roughly stable despite growth in the economy and population. But where all heck has broken loose is in how this power is being generated (data via the EIA).
In a few years, wind and solar combined (red line) will blow by coal as well. With wind and solar, the big enticement for power generators is that the “fuel” is free and that there won’t be any “fuel” price increases in the future, no matter what inflation will do:Electricity Has Been in a Slump for 14 Years, But All Heck Has Broken Loose in How it’s Generated | Wolf Street
