The energy sources the companies use vary. Some of them include some wind, hydro, solar and bimass, a category that includes landfill gas and other plants that create energy from organic sources. All of the electricity is produced within the Mid-Atlantic region. Please be aware that with most clean products, you will still receive a monthly bill from your standard utility company, but the clean product will be listed on your bill.

Some of the products are Green-e certified, indicating that they have undergone an independent certification process through the non-profit Center for Resource Solutions. The Green-e process ensures that the companies and products meet consumer protection and environmental standards. For more information, see www.green-e.org or call 1-888-63-GREEN.
