The National Renewable Energy Laboratory (NREL) aims to provide credible, objective data and insights that inform policy and investment decisions as energy efficient and renewable energy technologies advance from concept to commercial application. NREL analysis encompasses a broad range of scientific research and reporting activity in support of the U.S. Department of Energy's (DOE) Office of Energy Efficiency and Renewable Energy (EERE), NREL programs and initiatives, and the analysis community.

Estimated annual voluntary sales by market sector show a rise in green power markets
a Voluntary sales for 2011 are estimated as the mid-point of 2010 and 2012 sales.
With voluntary green power markets, consumers and institutions voluntarily purchase renewable energy to match their electricity needs. Voluntary action provides a revenue stream for renewable energy projects and raises consumer awareness of the benefits of renewable energy. These markets continued to exhibit growth and stimulate renewable energy development in 2012.
Status and Trends in the U.S. Voluntary Green Power Market (2012 Data) by Jenny Heeter and Terry Nicholas reviews the voluntary market and identifies market trends. The voluntary green power market totaled more than 48 million MWh in 2012, with about 1.9 million customers participating. The supply continues to be dominated by wind, though solar is increasing its share of utility green pricing programs. Prices for voluntary renewable energy certificates (RECs) increased to above $1/MWh.
Jenny Heeter presented a summary of the report titled "Current State of the Voluntary Renewable Energy Market" at the Renewable Energy Markets Conference 2013.
NREL, in collaboration with India's Ministry of New and Renewable Energy (MNRE), has created the Indian Renewable Energy and Energy Efficiency Policy Database (IREEED) to disseminate information on renewable energy and energy efficiency policies established by the central and state governments in India. IREEED, developed under the U.S.-India Energy Dialogue and the Clean Energy Solution Center, is an online database that provides succinct policy information for consumers, businesses, project developers, and policymakers. IREEED includes:
- Summaries of policies, regulations, and incentive programs for the central government and all states in India
- Faceted search function
- Links to policy and regulatory documentation
- Links to resources on energy efficiency and renewable energy
- Summary information on the most pertinent policy types, including generation-based incentives and renewable purchase obligations
- User feedback form.

NREL Report: Low Emission Development Strategies: The Role of Networks and Knowledge Platforms
Authors: Ron Benioff, Morgan Bazilian, Sadie Cox, and Caroline Uriarte, NREL; Ana Kecman, Giuseppe De Simone, Kazuki Kitaoka, and Marina Ploutakhina, United Nations Industrial Development Organization; Mark Radka, United Nations Environment Programme
The authors present a review of strengths and weaknesses of existing low-emissions developments strategies (LEDS) networks that build on the findings of a study conducted by the Coordinated Low Emission Assistance Network (CLEAN). Based on the insights from theory and a mapping of the climate-related network space, opportunities for further refinement of LEDS networks are identified.
