The National Renewable Energy Laboratory (NREL) is the United States federal research laboratory dedicated to renewable energy and energy efficiency. Based in Golden, Colorado, it shapes global renewable technology through research, testing, and deployment support.
What NREL is
NREL is one of 17 US Department of Energy national laboratories. Established in 1974 as the Solar Energy Research Institute; renamed NREL in 1991. Operated by the Alliance for Sustainable Energy under contract to DOE. About 3,000 employees.
Mission
NREL research areas cover the full renewable spectrum: solar photovoltaics, wind, geothermal, hydrogen, bioenergy, energy storage, buildings, sustainable transportation, and grid modernization. Research spans fundamental science through commercial deployment support.
Major programme areas
| Area | Notable work |
|---|---|
| Solar PV | Cell efficiency records, silicon and thin film |
| Concentrating solar power | Thermal storage integration |
| Wind | Turbine design, offshore wind resource |
| Geothermal | EGS technology, direct use applications |
| Hydrogen | Electrolysis, storage, fuel cells |
| Bioenergy | Sustainable feedstocks, biofuels, biomass |
| Buildings | Energy efficiency, heat pumps, envelope |
| Grid modernization | Grid forming inverters, storage integration |
| Transportation | Electric vehicles, alternative fuels, mobility |
Notable public tools
- PVWatts. Solar potential estimator used globally for site assessment. See PVWatts.
