Top 30 On-Site icon.The Top 30 On-site Generation list represents those partners generating and consuming the most green power on-site within the Green Power Partnership. The combined on-site green power consumption of these organizations amounts to nearly 921 million kilowatt-hours of green power annually, which is equivalent to the electricity use of more than 87,000 average American homes each year.

We are honored that the EPA has recognized us for the renewable energy generated by the Volkswagen Chattanooga Solar Park. Generating green power onsite is an important part of Volkswagen's efforts to be responsible for our footprint in everything from powering our planet to powering our cars.
- Frank Fischer, Volkswagen Chattanooga

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:
