The IEEJ: Japan's Unrealistic Gas Forecasts
This fact sheet by Zero Carbon Analytics analyzes the energy forecasts of the Institute for Energy Economics Japan (IEEJ), arguing that the institute projects unrealistically high future gas demand compared to the IEA, ExxonMobil, and BP. The document attributes these high forecasts to the IEEJ's assumptions regarding the high cost of renewables, a preference for thermal power as a backup, and an optimistic outlook for carbon capture and storage (CCS).

COMPARING INFLATION REDUCTION ACT MODELING TO THE ANNUAL ENERGY OUTLOOK
This research note by Energy Innovation compares its own modeling of the Inflation Reduction Act (IRA) with the U.S. Energy Information Administration's (EIA) Annual Energy Outlook (AEO) 2023. The authors argue that the AEO underestimates the IRA's impact on emissions reductions and clean energy deployment, particularly in the electricity and transportation sectors, due to differences in model scope, tax credit inclusion, and economic assumptions.

Using the State Energy Policy Simulator to Support Climate Pollution Reduction Grant Planning
This fact sheet describes the Energy Policy Simulator (EPS), an open-source tool developed by RMI and Energy Innovation to help states estimate the impacts of climate and energy policies. It specifically outlines how the EPS can be used by state governments to meet the requirements of the Climate Pollution Reduction Grant (CPRG) program, including GHG inventory, emissions projections, and benefits analysis.

Low Emissions Analysis Platform Training Exercises
This guide provides a series of modular training exercises for the Low Emissions Analysis Platform (LEAP) 2020 software. Using a fictional country called "Freedonia" and a hypothetical region called "Transportia," the document instructs users on how to model energy demand, transformation processes, emissions, cost-benefit analyses, and least-cost optimization for energy systems.
