WHAT E3+ HELPS YOU ANSWER
Better questions.
Smarter environmental and energy policy.
E3+ turns energy and environmental decisions into clear economic answers—so you can weigh tradeoffs, compare alternatives, and demonstrate the full economic impact of policy with confidence.
How will changing electric rates affect the economy?
Estimate the impact of utility rate changes on jobs, output, and household costs across the region.
What is the economic impact of new power sources?
Evaluate how new generation—renewable, nuclear, or conventional—affects the broader economy.
How do emissions rules affect jobs and output?
Quantify the economic effects of regulations on emissions, pollution, and greenhouse gases.
What is the cost of the clean energy transition?
Weigh the long-term economic benefits of energy transition strategies against their costs.
Which regions and industries are most affected?
Identify the geographies and sectors that gain or lose under different energy scenarios.
How do scenarios compare to a baseline?
Compare alternative energy and environmental scenarios against a baseline to isolate the true impact.

Methodology & Data
Powered by the REMI engine.
Tuned for energy and the environment.
E3+ pairs the proven REMI modeling framework with energy- and environment-specific detail—turning rate changes, new power sources, and emissions policies into a complete, credible picture of economic impact.
Our methodology
E3+ translates an energy or environmental policy into economic outcomes through a transparent, repeatable process built on the REMI framework.
Define the Policy
Specify the rate change, power source, emissions rule, or investment you want to evaluate.
Set Energy & Environmental Inputs
Layer in generation, fuel, rate, and emissions changes as economic inputs.
Add Costs & Externalities
Account for investment, operating, and environmental costs and benefits.
Run the Model
E3+ links those inputs to the REMI engine to simulate the full economic response, year by year.
Analyze Results
Explore outcomes across jobs, output, income, and population for any geography and time horizon.
Compare to Baseline
Weigh the policy against a no-change baseline to isolate its true economic impact.
Energy & environmental data sources
E3+ combines energy and environmental data with the same trusted economic data that powers PI+.
