Voluntary Green Power Procurement

NREL has tracked status and trends in the voluntary green power market since its inception in the 1990s. This work can help corporate purchasers, utilities, and others selling renewable energy products understand available renewable options and move renewable energy forward to meet goals such as state renewable portfolio standards (RPSs).

The latest version of NREL's annual tracking of the voluntary market found that the U.S. voluntary green power market grew to 77.9 million megawatt-hours (MWh) sold to 4.3 million customers in 2015. The report covers trends in utility green pricing programs, utility green tariffs, competitive suppliers, unbundled renewable energy certificates, community choice aggregations, power purchase agreements, and community solar.

Renewable Electricity Use by the U.S. Information and Communication Technology (ICT) IndustryPDF
This analysis examines renewable electricity use by 113 ICT companies in the United States using data from the U.S. Environmental Protection Agency's Green Power Partnership and the Carbon Disclosure Project Worldwide. The 113 ICT companies examined collectively consumed more than 59 million MWh of electricity in 2014, which represents 1.5% of the total U.S. electricity consumption. Of the 59 million MWh, 14% (8.3 million MWh) was sourced from voluntary renewable electricity.
