Data and Resources

The following data and resources include procedures, databases, maps, and tools produced by NREL. These resources are available to assess, analyze, and optimize renewable energy and energy efficiency technologies for your project.

Annual Technology Baseline and Standard Scenarios

This study provides an annual process designed to ensure consistent application of a realistic and timely set of input assumptions and consider a diverse set of potential futures.

Open EI (Open Energy Information)

OpenEI is a knowledge sharing online community providing energy information and data via geographic discovery, visualizations and apps, and topic-oriented gateways.

The Energy DataBus

Open-source software that collects massive amounts of energy-related data at second-to-second intervals.

Renewable Energy Technology Maps

Dynamic and static maps for various renewable resources and for specific projects. provides information on federal initiatives that support the development of Smart Grid technologies, policies and projects transforming the electric power industry.

GIS Datasets

Technology-specific datasets, designed for use in GIS software applications, for a variety of areas, including biomass, geothermal, solar, wind, and renewable hydrogen.

Transparent Cost Database (TCDB)

Compares U.S. DOE EERE program cost and performance estimates for vehicles, biofuels, and electricity generation technologies with other published data. All data are downloadable for full transparency.

Wind Integration Datasets

The Wind Integration Datasets provide energy professionals with a consistent set of wind profiles for the eastern United States and the western United States. Both datasets provide ten-minute time-series wind data for 2004, 2005, and 2006.

Building Energy Data Book

Provides statistics on residential and commercial building energy consumption.

Renewable Energy Data Book

Provides facts and figures on energy and renewable electricity investments and use in the United States and around the world.

NREL Renewable Energy Project Finance

Provides information on the Solar Access to Public Capital working group, Market Insights blog, finance reports, standard contracts, and additional NREL project finance information.

Utility Rate Database

A free storehouse of rate structure information from utilities in the United States. These rates are provided in a computer-readable format for use in user-developed tools and models.

OpenEI Incentives and Policies for RE and EE

DSIRE provides comprehensive, up-to-date information on state, local, federal, and utility incentives and policies for renewable energy and energy efficiency.


Between 2009 and 2012, the Renewable Energy Finance Tracking Initiative (REFTI) gathered project financing terms including debt interest rates, equity returns, and PPA duration.

Other Data and Resources

  • The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) summarizes select sources of data and online maps on energy efficiency and renewable energy technologies.
  • EERE's Green Power Network provides up-to-date information on green power providers, product offerings, consumer protection issues, and policies affecting green power markets. It also includes a reference library of papers, articles and reports.
