US renewable energy farms outstrip 99% of coal plants economically
01 Feb 2023
Coal in the US is now being economically outmatched by renewables
to such an extent that it’s more expensive for 99% of the country’s coal-fired
power plants to keep running than it is to build an entirely new solar or wind
energy operation nearby, a new analysis has found.
The
plummeting cost of renewable energy, which has been supercharged by last year’s
Inflation Reduction Act, means that it is cheaper to build an array of solar
panels or a cluster of new wind turbines and connect them to the grid than it
is to keep operating all of the 210 coal plants in the contiguous US, bar
one, according to the study.
“Coal
is unequivocally more expensive than wind and solar resources, it’s just no
longer cost competitive with renewables,” said Michelle Solomon, a policy
analyst at Energy Innovation, which undertook the analysis. “This report
certainly challenges the narrative that coal is here to stay.”
The
new analysis, conducted in the wake of the $370bn in tax credits and other
support for clean energy passed by Democrats in last summer’s Inflation
Reduction Act, compared the fuel, running, and maintenance cost of America’s
coal fleet with the building of new solar or wind from scratch in the same
utility region
