YANKTON, S.D.(WNAX)- In the wake of the winter storm, a polar blast will envelop most of the country, pushing up energy usage.

Brian Bird, incoming C.E.O. of Northwestern Energy, says most Americans don’t realize how much others in the world pay for energy.

Bird says natural gas costs will continue to be on the high side.

Bird says natural gas supplies are struggling to meet demand right now.

Bird says they expect their supply of natural gas will be adequate for the winter.
