The Green Energy program purchases Renewable Energy Certificates (RECs) on behalf of its participants. A REC represents the property rights to the environmental, social, and other non-power benefits of 1,000 kilowatt hours (kWh) of renewable electricity generation. As renewable generators produce electricity, they have a positive impact, reducing the need for fossil fuel-based generation sources. RECs embody these positive environmental impacts and convey these benefits to the REC owner.
The pie chart shows the percentage of RECs purchased by the Green Energy program in the current year, by their associated renewable type and the state from which they were sourced. Also included is information on the historical REC resource mix, REC purchases made by the program per year, and the amount of renewable kWh each $5 and $13 block supported by month and year.
