Relating to: net zero emissions, carbon-free and renewable energy standards, and creating an office of sustainability and clean energy, granting rule-making authority, making an appropriation, and providing a penalty. (FE)

This bill establishes a comprehensive clean energy framework requiring Wisconsin to achieve 100 percent clean electricity production and net-zero carbon emissions by 2050. It creates a new Office of Sustainability and Clean Energy within the Department of Administration to develop and update an economy-wide decarbonization roadmap using sector-based modeling. The legislation sets specific interim targets for carbon-free electricity, including 50 percent by 2030, 65 percent by 2035, 80 percent by 2040, 90 percent by 2045, and full carbon-free status by 2050. State agencies must consider purchasing renewable energy from providers with long-term contracts, though the requirements do not apply if generation is not technically feasible or cost-effective. The bill also provides funding for technology implementation and defines carbon-free resources to include hydroelectric power alongside other renewable sources.
