Green Power Partnership

Green Power Community Challenge

Launched in September 2013, EPA hosted its fourth national, year-long campaign to encourage communities coast-to-coast to use renewable energy and fight climate change. As part of the campaign, Communities competed to see which one could achieve the highest green power percentage of total electricity use and which one could use the most green power.

And the winners are . . .

EPA declared the winning communities on September 22, 2014:

Most kilowatt-hours of green power: Washington, D.C. Green Power Community
The EPA Green Power Community of Washington, D.C., won the Challenge title of using the greatest amount of green power annually. District Government, businesses, and residents are collectively purchasing nearly 1.2 billion kilowatt-hours (kWh) of green power annually, enough green power to meet nearly 13 percent of the community's total electricity use.

Highest percentage of green power: Hillsboro, Ore. Green Power Community
The EPA Green Power Community of Hillsboro, Ore. led the Challenge competition of achieving the highest green power percentage of total electricity use. Nearly 51 percent of Hillsboro’s local government, residential, and business electricity usage comes from green power sources.

At the conclusion of the Challenge, EPA’s Green Power Communities were collectively using more than five billion kWh of green power annually, avoiding greenhouse gas emissions equal to the carbon dioxide emissions (CO2) from the annual electricity use of more than 515,000 homes.

Who Participated?

To participate, a local city, town, village, county, or tribal governments must become an EPA Green Power Community. At the conclusion of the Challenge, 53 EPA Green Power Communities competed in the Challenge. View the final Green Power Community Challenge Rankings.

How Did The Challenge Work?

Over the span of a year, EPA GPCs tracked and reported their collective green power use and green power percentage of total electricity use. EPA provided technical and outreach assistance to participants throughout the Challenge to help them increase their green power usage rates.

GPCs were ranked according to these categories on EPA's website on a quarterly schedule. Learn more about the GPC Challenge (PDF) (2 pp, 811K, About PDF).

Is EPA Planning on Continuing the GPC Challenge?

Yes! EPA will announce the kickoff of the next Green Power Community Challenge in early 2015.
