Trump DoE to critique renewables against coal for grid reliability

Trump DoE to critique renewables against coal for grid reliability

It is widely accepted in the energy industry that U.S. coal production will fall as a percentage of the total electric grid mix. That has little to do with its high carbon footprint per kilowatt-hour generated; it is largely due to far greater supplies of much cheaper fracked natural gas. It is... read more
