The free and open-source Vitality Coverage Simulator (EPS) pc mannequin developed by Vitality Innovation Coverage & Know-how LLCTM has turn out to be one of the vital broadly used instruments to tell policymakers and regulators about which local weather and vitality insurance policies will scale back greenhouse fuel emissions most successfully, creating the biggest financial and public well being advantages.
With EPS fashions now utilized in 10 nations and 48 states throughout America, we’re typically requested how the EPS works and what peer evaluation it has undergone by way of its growth.
The EPS is a System Dynamics pc mannequin created in Vensim, a software produced by Ventana Programs for the creation and simulation of System Dynamics fashions. The mannequin is designed for use with the free Vensim Mannequin Reader, and instructions on acquiring Vensim Mannequin Reader and the EPS can be found on the Obtain and Set up web page. As an open-source modeling software, customers can entry the mannequin by way of the energypolicy.options web site. To make use of superior options or modify its enter knowledge, customers might obtain the EPS and run it domestically on their Mac or Home windows PC. All the enter knowledge is meticulously cited, publicly out there, and freely accessible and editable, with outcomes up to date immediately.
The EPS permits customers to mannequin quite a few insurance policies that have an effect on vitality use and emissions together with a renewable portfolio normal, gas financial system requirements for autos, trade methane requirements, incentives for clear vitality applied sciences like we see within the Inflation Discount Act, and accelerated R&D development of assorted applied sciences. These insurance policies will be utilized throughout each main sector of the financial system together with transportation, electrical energy provide, buildings, trade, agriculture, and land use. The EPS additionally consists of smaller elements like hydrogen provide, district warmth, waste administration, and geoengineering.
The mannequin experiences outputs at annual intervals and gives quite a few outputs, together with:
- Emissions of 12 completely different pollution together with carbon dioxide, nitrogen oxides, sulfur oxides, and advantageous particulate matter, in addition to carbon dioxide equal (CO2e) which measures the worldwide warming potential of assorted pollution.
- Direct money move (price or financial savings) impacts on authorities, non-energy industries, labor and customers, and 5 energy-supplying industries.
- Direct, oblique, and induced impacts on jobs, GDP, and worker compensation, as an entire or disaggregated into 36 financial classes.
- Untimely mortality and 10 different health-related outcomes prevented from decreased main and secondary particulate air pollution.
- The composition and output of the electrical energy sector (e.g., capability and era from coal, pure fuel, wind, photo voltaic, and many others.).
- Automobile expertise market shares and fleet composition together with electrical autos.
- Vitality use by gas kind from numerous energy-using applied sciences together with particular forms of autos and constructing elements.
- Breakdowns of how every coverage inside a coverage bundle contributes to complete abatement and the cost-effectiveness of every coverage (e.g., wedge diagrams and price curves).
- Gas imports and exports, and related expenditures or revenues.
All methodologies underpinning the EPS have undergone intensive peer evaluation as they had been developed, and we frequently search enter from outdoors consultants to switch the methodologies to handle any issues which might be raised. Parts of the mannequin have been reviewed by people from prestigious establishments together with:
- American Council for an Vitality-Environment friendly Economic system
- Argonne Nationwide Laboratory
- Lawrence Berkeley Nationwide Laboratory
- Massachusetts Institute of Know-how
- Nationwide Renewable Vitality Laboratory
- RMI
- Stanford College
- Tufts College
- College of Chicago
- U.S. Environmental Safety Company
- World Sources Institute
Nationwide labs, universities, and companions who’ve peer reviewed the Vitality Coverage Simulator
