The report includes both demand driven by existing state RPS policies, as well as demand in the voluntary renewable market.

Renewable Energy Certificate Tracking Systems

Because Renewable Energy Certificates (RECs) can be sold separately from the underlying electricity, the possibility for fraud can exist unless the RECs are tracked from their point of creation to their final point of use. EPA's Green Power Partnership provides an overview of REC tracking systems, including a map of the regional tracking systems that have been developed in the United States.

State of the States 2009: Renewable Energy Development and the Role of Policy

This National Renewable Energy Laboratory report (PDF) (231pp, 4.3MB) Exit EPA disclaimer provides a detailed picture of the status of renewable energy development in each of the U.S. states using a variety of metrics and discusses the policies being used to encourage this development. The report explores the context in which renewable energy development occurs by discussing the factors that can affect the uptake of power generation technologies. The analysis offers suggestions on how policies can be used to address these variables, which leads to tailored policy support that considers the specific circumstances within each state.

Forest Inventory Data Online (FIDO)

This online tool provides access to the National Forest Inventory and Analysis databases Exit EPA disclaimer. It can be used to generate tables and maps of forest statistics by running standard reports for a specific state or county and survey year, or customized reports based on criteria selected by the user.

Landfill Methane Outreach Program (LMOP) Landfill Database

The Landfill Methane Outreach Program (LMOP) Landfill Database provides a nationwide listing of operational and under construction LFG energy projects; candidate municipal solid waste landfills having LFG energy potential; and information on additional landfills that could represent LFG energy opportunities.

Market Opportunities for Biogas Recovery Systems

This report (PDF) (40 pp, 3.05M) assesses the market potential for biogas energy projects at swine and dairy farms in the United States. For the top ten swine and dairy states, the guide characterizes the sizes and types of operations where biogas projects are technically feasible, along with estimates of potential methane production, electricity generation, and greenhouse gas emission reductions.

Connecting to the Grid

The Interstate Renewable Energy Council's Connecting to the Grid program Exit EPA disclaimer provides services and resources to facilitate the development of interconnection procedures and net metering rules for renewable–energy systems and other forms of distributed generation.

Open PV Mapping Project

Open PV Mapping Project is a collaborative effort between government, industry, and the public to develop a comprehensive database of photovoltaic (PV) installation data for the United States. The project includes over 50,000 installations and provides a Web-based resource for users to easily understand the current status and past progress of the PV industry.

States Advancing Solar

The States Advancing Solar Resource Center is a continuously updated list of reports and other publications regarding solar technologies and state solar programs. The materials are seachable by title, author, and by topic categories.

Solar Energy Technologies Program

The Solar Energy Technologies Program focuses on developing cost-effective solar energy technologies that have the greatest potential to benefit the nation and the world. Subprograms focus on photovoltaics, concentrating solar power, systems integration, and market transformation.

Solar Photovoltaic Financing on Public Property

National Renewable Energy Laboratory's 2008 report, Solar Photovoltaic Financing: Deployment on Public Property by State and Local Governments (PDF) (72 pp, 1.14M), discusses structures of public-sector PV financing, industry trends, barriers to implementation, and state and local government examples of PV deployment.

Solar Power Purchase Agreements

A Solar Power Purchase Agreement (SPPA) is a financial arrangement in which a third-party developer owns, operates, and maintains a photovoltaic (PV) system, and a customer hosts the system on its property and purchases the system's electric output for a predetermined period. EPA's Green Power Partnership has developed a Web page to provide information on SPPAs, how they are structured, and the benefits and challenges of implementing them.
