You can have 100 percent of your electricity use matched by renewable energy credits for $0.65 per 100 kWh based on your monthly average energy use over a 12-month period. For example, if you use an average of 820 kWhs per month, then you would subscribe to nine Evergreen blocks for $9 per month and know everything you power is being matched by renewable energy. Average electricity use will be re-calculated on an annual basis. (Contact the office for assistance will determining your monthly average usage.)
