Rhodium’s Global Energy Model (RHG-GEM) provides a robust and systematic exploration of the main drivers of regional energy demand, technology deployment, and resulting greenhouse gas emissions through the end of the century.
Rhodium’s Global Energy Model (RHG-GEM) is designed to consider a wide-range of uncertainties underpinning the global energy system, providing a robust and systematic exploration of the main drivers of regional energy demand, technology deployment, and resulting greenhouse gas emissions through the end of the century. RHG-GEM is the basis for the annual Rhodium Climate Outlook, which provides insights into what climate future the world is on track for, by integrating probabilistic energy and GHG emissions outcomes with a climate model to generate probabilistic temperature rise estimates incorporating climate system uncertainty.
Rhodium’s Global Energy Model (RHG-GEM) is an integrated modeling platform that captures uncertainty in the pace of economic and population growth, oil and natural gas prices, clean energy technology costs and policy to provide probabilistic energy, and emissions projections through the end of the century. Global emissions are coupled with a simple climate model to produce internally-consistent probabilistic global average temperature rise projections. RHG-GEM is a technology-rich market equilibrium model that identifies the most efficient and economically viable pathways to meet global and regional energy demands, aligned with policy constraints, firm and consumer behavior, and technology evolution and costs. With the addition of full Monte Carlo capabilities, RHG-GEM can provide probabilistic projections of energy demand, technology deployment, greenhouse gas emissions and temperature rise, taking into account the inherent uncertainty in global and regional developments.
Our team uses RHG-GEM to assess the impact of current and prospective policies, technology investment and innovation on regional and global energy system outcomes, technology deployment and costs, greenhouse gas emissions and the resulting global temperature rise outcomes.
The need to understand what kind of climate and energy future the world is on track for has become increasingly important not just for diplomats and policymakers, but to almost every actor of the global economy. In an increasingly complex and uncertain world, all need access to modeling that incorporates uncertainty in factors over which they have no control—variables like policy, fuel prices, and economic growth. Rhodium’s Global Energy Model seeks to address some of the shortcomings of existing modeling with probabilistic energy, emissions, and temperature projections by incorporating the following innovations, which to our knowledge have never been combined in a single modeling platform:
Other features of RHG-GEM include:
RHG-GEM is the modeling platform used to produce the Rhodium Climate Outlook each year, which provides probabilistic projections of the likely evolution of greenhouse gas emissions and associated temperature rise through the end of the century, and insights into what will matter most for decarbonization in the coming decades.
