Description of model

The National Energy Modelling System (NEMS) is a computer-based, energy-economy modelling system of U.S. energy markets.  NEMS forecasts the production, imports, conversion, consumption, and prices of energy.  The inputs to the model include assumptions on macroeconomic and financial factors, world energy markets, resource availability and costs, behavioural and technological choice criteria, cost and performance characteristics of energy technologies, and demographics.  The model can then be used to look at a range of response measures but is particularly well-suited to assessing technological solutions.

Particular relevance

NEMS is relevant to assessment of the response measures through its treatment of the adoption of new energy technologies.



Model applications

Annual Energy Outlook - The EIA's 2009 report was updated to reflect the provisions of the American Recovery and Reinvestment Act (ARRA) that were enacted in mid-February 2009. The report is based on NEMS model output based on the its interpretation of the set of policies in the ARRA (
