NC GreenPower is an independent, nonprofit organization established to improve North Carolina’s environment through voluntary contributions toward renewable energy and the mitigation of greenhouse gases. A landmark initiative approved by the N.C. Utilities Commission, NC GreenPower is the first statewide green energy program in the nation supported by all the state’s utilities and administered by Advanced Energy, an independent nonprofit corporation located in Raleigh, N.C. The goal of NC GreenPower is to supplement the state’s existing power supply with more green energy – electricity generated from renewable energy sources like the sun, wind and organic matter. As of 2008, NC GreenPower also offers carbon offsets to address growing concerns about the impact of greenhouse gases on the environment. The program accepts financial contributions from citizens and businesses to help offset the cost to produce green energy. There is no limit on the number of $4 blocks an individual, organization or business can purchase.
