The essence of green power marketing is to provide market-based choices for electricity consumers to purchase power from environmentally preferred sources. The term "green power" is used to define power generated from renewable energy sources, such as wind and solar power, geothermal, hydropower and various forms of biomass. 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. You can find more information about purchase options on our "Buying Green Power" page.

Green pricing is an optional utility service that allows customers an opportunity to support a greater level of utility company investment in renewable energy technologies. Participating customers pay a premium on their electric bill to cover the incremental cost of the additional renewable energy. As of early 2006, more than 600 utilities across the nation, including investor-owned, municipal utilities, and cooperatives, offer a green pricing option.

Solar panels are increasingly efficient and inexpensive.  Often, municipalities offer rebates for residential customers willing to try green power, so ask your local government for more information. There may be incentives on the state and federal level as well.  

For often under $25 a month, the typical homeowner can make sure his or her entire house is powered by windmills.   *ref needed
