The cost of energy for Washington, D.C., residents has been rising.

In June, the district’s Public Service Commission approved Pepco’s request to increase electricity rates by $109 million over three years. In May, gas at the pump broke the $3 mark in May for the first time in the area since the mid-2010s. August prices are 50% higher than last year’s. Natural gas for home heating this summer hit $1.55 per therm, up 20% from last year.
