The free, open-source Energy Policy Simulator is a tool to evaluate climate policies and visualize impacts on cash flow, job growth, emissions, power plants, and more. Energy Innovation Policy & Technology LLC® and RMI developed U.S. state Energy Policy Simulators (EPS) for the contiguous 48 states, providing information on a wide range of state policies and their combined impact on greenhouse gas emissions, public health, employment, and economic growth within a single state. The U.S. state EPS models are built using publicly available state and downscaled federal data from sources such as the Bureau of Economic Analysis, the Bureau of Labor Statistics, the Energy Information Administration, the Environmental Protection Agency, and the National Renewable Energy Laboratory, and others. The models incorporate existing federal and state policy, excluding the Inflation Reduction Act. More information on our sources and methodology is available as part of our documentation.

The U.S. state EPS models can be run online and downloaded to run locally using free software. Greenhouse gas (GHG) emissions are reported in carbon dioxide equivalent (CO2e) using 100-year global warming potential values from the IPCC’s Fifth Assessment Report.
