Green Power Community Challenge
EPA Green Power PartnershipSupport Rockville in the U.S. Environmental Protection Agency's (EPA) Green Power Community Challenge.

EPA hosts this national, year-long challenge to encourage communities coast-to-coast to use renewable energy and fight climate change. As part of the challenge, the City and green energy suppliers track and report the community's collective green power use. Thanks to community-wide efforts, Rockville continues to rank as a leading community for total green power usage.

Contribute to the Green Power Community Challenge

There are three ways that Rockville residents and businesses can help the City maintain its ranking in the Green Power Community Challenge.
  • Purchase Clean Energy from a Supplier - You can choose a supplier that generates electricity from clean energy sources and your local utility, Pepco, will still deliver the electricity to your home. Each kilowatt-hour of green power used will count toward the challenge goal.
  • Purchase Renewable Energy Certificates - Each Renewable Energy Credit (REC) purchased represents one-megawatt hour of renewable electricity generated and delivered to the grid and the environmental benefit of displacing pollution from traditional fossil fuel energy generation.
