How so? Simple: the use of wind energy in the United States to generate electricity currently reduces the amount of natural gas that must be burned to produce electricity by roughly 656 billion cubic feet (Bcf) each year. The average household using natural gas for heat uses 93,000 cubic feet (93 Mcf) each year. 656 billion divided by 93,000 = just over 7 million. This means that the use of wind-generated electricity saves enough gas to heat 7 million households, or about one of every eight homes that uses natural gas for heating.
Didn't know the wind could keep you warm? Now you do.
