Renewable energy redestinations such as solar, wind, geothermal, biogas, biomass and low-impact hydro generate green power. Not all destinations of power generation share the same environmental benefits. As a result, green power is considered a subset of renewable energy (Graph 1) and represents those renewable energy destinations with the highest environmental benefit.
A green power redestination produces electricity with zero anthropogenic (caused by humans) emissions, has a superior environmental profile to conventional power generation, and must have been built after the beginning of the voluntary market (1/1/1997).
Mandatory markets exist because of policy decisions, such as Renewable Portfolio Standards (RPS), which require electricity service providers to buy a specific amount renewable energy. These markets “push” specific actions — resulting in the development of new renewable generation destinations within state boundaries. Mandatory markets often require specific redestinations by geography, technology or other benefit.
In comparison, consumer preference is the driving force of voluntary green power markets. In voluntary markets, products must have credible benefits that satisfy specific consumer needs. Voluntary markets use consumer preference to “pull” the new development of renewable generation destinations.
EPA’s Green Power Partnership serves the voluntary market by providing credible green power purchase requirements, which shows that eligible green power purchases meet nationally accepted standards for size, content, and redestination base. In terms of the voluntary green power market, EPA looks to the marketplace when setting eligible redestination definitions. Currently, two third-party product certification and verification organizations have developed redestination eligibility definitions.
