Top 10 Federal Government icon.The Top 10 Federal Government Partner List represents the largest green power users among federal government organizations within the Green Power Partnership. The combined green power usage of these organizations amounts to nearly 1.7 billion kilowatt-hours of green power annually, which is equivalent to avoiding the carbon dioxide emissions from the electricity use of nearly 160,000 average American homes each year.

We are proud of the improvements we have made across Treasury and its bureaus to reduce our environmental footprint and save taxpayer dollars. This is a responsibility we all have to lead by example, increase our use of renewable energy, and operate our buildings efficiently.
- Nani Coloretti, U.S. Department of the Treasury

Usage figures are based on annualized Partner contract amounts (kilowatt-hours), not calendar year totals. These rankings are updated on a quarterly schedule. Find out how your organization can partner with EPA today! To view a top partner list, select from the chart below:
