Accounting for politics in green energy transitions

Accounting for politics in green energy transitions
Image: Simulation of renewable energy share in the United States, 2013-20260. AR5 450 ppm is a transition necessary for the U.S. to support the 450 ppm mitigation pathway in the IPCC Fifth Assessment Report. Colored lines and prediction bands show mean and standard deviations around modeled scenarios, across different possible election results. 

Politics plays a hand in how, and whether, a nation transitions to renewable energy. But despite the significant effects of policy on technological progress, few growth projections for renewables take political dynamics into account.

A new computational model by SFI Omidyar Fellow Marion Dumas and colleagues adds a layer of complexity to the existing models, by forecasting 50-year carbon emissions under differing political scenarios.

"Models that try to understand the dynamics of these [energy] technologies don't incorporate political competition," Dumas explains, "but political competition interacts with the technology's dynamics. Certain actions taken today will affect the actions possible in the future."

The researcher's model frames empirical data on technological progression in the context of two competing political parties—a "green " and the "brown party" with differing degrees of commitment to their constituents. Among other findings, their model shows that winning an election early on has significantly greater impact on the 50-year trajectory than a later win, and a strong commitment from one party can force the less committed party to compromise.

The article, published in Ecological Economics, overlays 50-year political scenarios onto the 450 ppm carbon limit set by the Intergovernmental Panel for Climate Change (IPCC). According to Dumas, the United States is "still far from a situation where the green party is driving the dynamic, and supports a committed electorate. That's what's needed to avoid overshooting the IPCC's limit."
