Global warming news: Power rates may be going up because of polar vortex

Despite global warming, Chicago area consumers will may soon pay more for electricity and heat because of bitter cold weather.

From the Chicago Tribune:

Though the polar vortex seems a frost-bound memory, Chicagoans may now feel its bite in a new, unexpected way — higher electricity bills.

Beginning next month, power plants in northern Illinois and other states will be able to make more money from consumers in order to shore up electricity in frigid weather and prevent the scramble to keep the lights on that occurred during the extreme winter of 2013-14.
