From a news release issued by the Center for Climate Strategies:

Implementation of the recently introduced Clean Energy Jobs Act (CEJA) would expand the state’s economy and create thousands of additional new jobs for Wisconsin. These impacts are reported in a recent Center for Climate Strategies (CCS) analysis of the macroeconomic effects of the proposed law, conducted by Michigan State University and the University of Southern California in association with the State of Wisconsin. The analysis focuses on nine proposed policy actions that address clean and renewable energy, energy efficiency, industrial processes, transportation and agriculture.

Based on a state-of-the-art macroeconomic analysis, implementation of these CEJA actions would result in the following outcomes for Wisconsin:
 Create a net increase of more than 16,200 new jobs in the state by 2025;
 Boost the state’s economy (Gross State Product) by
o $254 million in the near term (2015),
o more than $700 million in 2020,
o $1.41 billion by 2025, and
o $4.9 billion total over the 2011-2025 period.
