Pathways to 100%

Rise Up

Eleven US states plus the District of Columbia have passed laws committing to 100% carbon-free or 100% clean energy. The path to 100% is full of choices that influence the cost to electricity ratepayers, ownership of critical infrastructure, and access to the financial and social benefits of energy infrastructure investment. A few detailed national studies have forecast scenarios to achieve 100% carbon-free electricity. These include net zero scenarios from Bloomberg New Energy Finance, the US Dept. Of Energy Solar Futures Study, and Vibrant Clean Energy’s Roadmap for the Lowest Cost Grid.

The national studies are informative, but state policy and regulation have significant influence over how state energy markets develop. This places responsibility on state leadership to define the most advantageous pathways and advance policies and programs to achieve them. In both Illinois and Minnesota, the recent legislation that established 100% clean energy goals was passed when the Democratic party held majorities in the legislatures and governors' offices. And the legislation passed on party-line votes. This is a clear indication that in Midwest states that have divided government, these types of commitments face political opposition.

One such state is Wisconsin, where Republicans hold sizable majorities in the assembly and senate while the state has a Democratic Governor with ambitious clean energy plans. In support of these plans, two state policy groups – Clean Wisconsin and Renew Wisconsin – partnered with GridLab and Evolved Energy Research to forecast scenarios for achieving 100% clean energy in Wisconsin by 2050. Using the scenarios, they produced a roadmap that demonstrates how Wisconsin can cost-effectively transition to net zero emissions. We discussed the study and its recommendations with Chelsea Chandler, program director at Clean Wisconsin.
