Typically, summer months are where Americans consume more electricity when running air conditioners to cool their homes. The graph below averaged the amount of electricity used by residents of Connecticut, Massachusetts, New Jersey, New York, Pennsylvania, Illinois, Michigan, Ohio, Delaware, DC, Maryland and Texas from April 2016-March 2017. The data used has been normalized so that the difference in number of days per month is equal in relativity.
Over the course of the year, it is clear that the amount of energy used in the summer surpasses any other time period. And when heat waves occur, this only increases.
The Southwestern US is facing an extreme heat wave with temperatures soaring to 117-120 F. Just this week in Phoenix, Arizona, the city used a record breaking amount of electricity, as temperatures hit 119 F.
