Green power sales in the United States have jumped dramatically -- and most of it comes from wind. The California-based Center for Resource Solutions (CRS) reports that sales of electricity certified under its Green-e program rose 76% in 2003, bringing total sales to 2.9 million MWh. Two-thirds of that amount, or 1,966,800 MWh, came from wind resources. The report also found that large non-residential purchases of renewable energy increased to more than half the volume of total Green-e retail sales in 2003 and that 88% of total sales were from new renewables. The market for tradable renewable credits (TRC) increased 12-fold to more than 1.8 million MWh, while utility green power sales grew 12%. In all, 91,000 residential customers and 2400 non-residential customers bought 1,915,000 MWh in 2003, an increase of 1,405,000 MWh. The CRS's Green-e program verifies renewable energy sales by participating utilities and Energy Service Suppliers, the designation for non-utility providers in the competitive markets. The CRS documents its findings in an annual Verification Report, published two years following the data collection to allow for verification. The 2003 Verification Report represents renewables sales for 102 marketers selling 37 Green-e products, 23 TRC products and five green pricing products.
