Innovative Energy Manufacturing Act of 2021 This bill provides for additional annual allocations, in 2022 through 2026, of the qualifying advanced energy project tax credit. A qualifying advanced energy project is a project that reequips, expands, or establishes a manufacturing facility for the production of energy from alternative sources, including solar, wind, or other renewable resources. The Department of the Treasury must report to Congress by the end of 2027 on domestic job creation attributable to the credit allocations made by this bill.
