State and Local Energy Data (SLED) 

Comprehensive energy use and activity data developed for the U.S. Department of Energy (DOE) that helps cities plan and implement clean energy projects. A city's energy profile includes summary reports on greenhouse gas emissions, electricity generation, natural gas and other fuel source costs, renewable energy resource potential, and more.

Tribal Energy Atlas 

First-of-its-kind interactive geospatial application that allows tribal energy project planners, technicians, and investors to conduct their own analyses of installed energy projects and resource potential on tribal lands.

Renewable Energy Optimization (REopt)

Identifies and prioritizes renewable energy projects at a single site, or across a portfolio of sites in multiple cities, states, or countries, each with its own energy requirements, resources, goals, and constraints.


Built for DOE on a proven open-source energy modeling framework, facilitates energy system planning, simulation, data management, and collaboration via a user-friendly, no-cost web application.

State and Local Planning for Energy (SLOPE) Beta 

Integrates energy efficiency and renewable energy data to more effectively support state and local energy planners and decision makers.

Alternative Fuels Data Center (AFDC)

Information, data, and tools developed for DOE to help fleets and other transportation decision makers find ways to reduce petroleum consumption.

OpenEI (Open Energy Information)

Knowledge sharing online community providing energy information and data via geographic discovery, visualizations and apps, and topic-oriented gateways.

System Advisor Model (SAM)

Makes performance predictions and cost of energy estimates for grid-connected power projects based on installation and operating costs, as well as system design parameters specified as inputs to the model.

Clean Energy Solutions Center

No-cost expert policy assistance, webinars and training forums, clean energy policy reports, data, and tools provided in partnership with more than 35 leading international and regional clean energy organizations.

Wind Exchange

Offers maps of wind resources and installed wind capacity, location-specific information, a bimonthly e-newsletter, webinars and podcasts, publications, and educational programs from DOE.
