Green power marketing provides market-based choices for electricity consumers to purchase power from environmentally preferred sources. The term "green power" defines power generated from renewable energy sources, such as wind power. Green power marketing has the potential to expand domestic markets for renewable energy technologies by fostering greater availability of renewable electric service options in retail markets. Although renewable energy development has traditionally been limited by cost considerations, customer choice allows consumer preferences for cleaner energy sources to be reflected in market transactions. In survey after survey, customers have expressed a preference and willingness to pay more, if necessary, for cleaner energy sources.
