The free and open-source Power Coverage Simulator (EPS) laptop mannequin developed by Power Innovation Coverage & Know-how LLC^TM has turn into one of the broadly used instruments to tell policymakers and regulators about which local weather and vitality insurance policies will scale back greenhouse gasoline 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 overview it has undergone by way of its growth.

The EPS is a System Dynamics laptop 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 through the energypolicy.options web site. To make use of superior options or modify its enter information, customers could obtain the EPS and run it domestically on their Mac or Home windows PC. The entire enter information is meticulously cited, publicly accessible, 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 customary, 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 varied 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 contains smaller elements like hydrogen provide, district warmth, waste administration, and geoengineering.

The mannequin stories outputs at annual intervals and offers quite a few outputs, together with:

Emissions of 12 totally different pollution together with carbon dioxide, nitrogen oxides, sulfur oxides, and superb particulate matter, in addition to carbon dioxide equal (CO₂e) which measures the worldwide warming potential of varied pollution.
Direct money stream (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 diminished major and secondary particulate air pollution.
The composition and output of the electrical energy sector (e.g., capability and era from coal, pure gasoline, wind, photo voltaic, and many others.).
Automobile know-how market shares and fleet composition together with electrical autos.
Power use by gas sort from numerous energy-using applied sciences together with particular kinds of autos and constructing elements.
Breakdowns of how every coverage inside a coverage bundle contributes to whole abatement and the cost-effectiveness of every coverage (e.g., wedge diagrams and value curves).
Gas imports and exports, and related expenditures or revenues.

All methodologies underpinning the EPS have undergone in depth peer overview as they had been developed, and we regularly search enter from outdoors specialists to switch the methodologies to deal with any issues which are raised. Parts of the mannequin have been reviewed by people from prestigious establishments together with:
