The repeal of green tax credits in the One Big Beautiful Bill Act significantly alters the United States' approach to clean energy, curtailing incentives that had stimulated investment and job growth in the solar, wind, and electric vehicle sectors. It also challenges prior assumptions about long-term tax expenditure planning and the role of tax policy in advancing environmental goals. Proponents argue that it improves fiscal discipline and simplifies the tax code by eliminating complex, industry-specific provisions. What is the net revenue impact of these changes over the next decade? Will they slow capital formation in energy markets? How will companies adjust their strategies to accommodate this change in policy priorities?  Will the quick repeal of these credits affect how companies react to future incentives?
