Use models and tools developed or supported by NREL to assess, analyze, and optimize renewable energy and energy efficiency technologies for your project. Many of these tools can be applied on a global, regional, local, or project basis. NREL models and tools include several designed for the consumer or energy professional.
Determine which supply chain changes would have the greatest potential to accelerate the deployment of biofuels.
Analyze capital investments in buildings. Includes the Energy Escalation Rate Calculator 2.0-15.
Simulate the potential adoption of distributed energy resources through 2050. Replaces the deprecated Solar Deployment System (SolarDS) model.
Helps building designers and owners save money, reduce energy use, and improve indoor air quality.
Designed to provide easy access to geothermal resource datasets and other data relevant to utility-scale geothermal power projects.
Estimates the electricity production of a grid-connected roof- or ground-mounted photovoltaic system based on a few simple inputs.
Determine optimal production and delivery scenarios for hydrogen, with this geospatial and temporal infrastructure analysis model.
Use NREL's geospatial toolkit to visualize solar and wind resource data in 13 developing countries.
Details on several resources that NREL maintains for supporting vehicle and transportation analysis.
See how changes in energy demand and supply by economic sector can impact carbon dioxide emissions.
Evaluate design options for both off-grid and grid-connected power systems for remote, stand-alone, and distributed generation applications. HOMER is licensed to and maintained by Homer Energy.
Access RE Atlas, Solar Power Prospector, PVWatts, and other popular tools that dynamically generate maps of renewable energy resources.
NREL uses this multi-regional, multi-time period, GIS and linear programming model of U.S. electric sector capacity expansion to analyze critical issues in the electric sector.
Early screening tool that identifies and prioritizes renewable energy projects using site, resource, cost, incentive, and financial data
Capacity expansion modeling to inform utility or regional electric system planning, including for clean energy or carbon mitigation analysis, in the Western or Eastern Interconnections. Contact Trieu Mai for more information.
NREL uses this capacity-expansion model of the U.S. energy market to conduct deterministic or stochastic analysis.
