"About half of U.S. clean energy now comes from solar and wind, and the other half from hydroelectric power."
The Energy Information Administration, the primary authority in the federal government on energy numbers, concludes that renewables, primarily hydro, wind and solar, rose to become 21% of electricity generation in the U.S. in 2020.
This
is the first time on record that renewables were the second-largest generator
of electricity in the U.S.
Renewables
overall increased 9% between 2019 and 2020. About half of U.S. clean energy now
comes from solar and wind, and the other half from hydroelectric power.
Wind
generation increased by 14%.
Solar
rocketed up even more, with utility-scale solar projects of 1 megawatt or more
growing by 26%.
Small-scale
solar such as rooftop installations like the one we have increased by 19%.
The Clean Power
Association says that America put in 26 gigawatts of renewables
electricity plants in 2020 — 80% more than in 2019 — bringing total US
renewables capacity to 170 gigawatts.
In
the US, some 78% of all new electricity generation was from wind and
solar, which are clearly the future of the American grid.
American
renewables beat out coal, now only 19%, and nuclear, at 20%. Coal is dirty and
expensive, and coal power plants have been replaced in droves by wind farms and
by natural gas. It was the largest generator of electricity in the US until
2016, and has gone into a tailspin because renewables and natural gas are much
cheaper.
h/t EIA
Natural
gas, which is only half as carbon intensive as coal, is now the leading
generator of electricity in the US, at some 40%.
Coal
electricity generation fell 20% from 2019 to 2020.
Between
renewables and nuclear, 41% of American electricity generation is now
low-carbon or no-carbon.
While
the increase clean gigawattage is impressive in American terms, China added 136
gigawatts of new renewables capacity in 2020, dwarfing the U.S.
effort. This massive lead that China has in wind and solar translates into
advantages in manufacturing, distribution and sales of equipment like solar
panels. The U.S., for all that it is finally making some strides, is going way
too slow if it wants to be a leader in these industries and if it wants to do
its part to keep global heating below an extra 3.6 degrees F.
