NorthWestern touts coal, natural gas, in meeting record energy demand

Last week, wind contributed more to power generation than coal for about 30 hours on the grid NorthWestern Energy oversees, according to data from the U.S. Energy Information Administration.

And for more than five days, generation from coal fell to nearly half its capacity, according to EIA data for the same region and period.

“It very much challenges and undermines the framing that fossil fuels run 24-7 and keep our lights on,” said Karin Kirk, a science writer for NASA Climate and journalist for Yale Climate Connections.
