US renewable energy farms outstrip 99% of coal plants economically – study
It is cheaper to build solar panels or cluster of wind turbines and connect them to the grid than to keep operating coal plants
“Coal is unequivocally more expensive than wind and solar resources, it’s just no longer cost competitive with renewables,”
On average, the marginal cost for the coal plants is $36 each megawatt hour, while new solar is about $24 each megawatt hour, or about a third cheaper.
