The IRA created roughly $370B in clean-energy tax credits over 10 years (some uncapped — Goldman Sachs estimates true cost $1T+). Major credits include:
- 45Y / 48E (production / investment) for clean electricity
- 45X for clean manufacturing (batteries, modules, components)
- 30D for new clean vehicles (consumer)
- 45V for clean hydrogen
- 45Q for carbon capture and sequestration
The credits are technology-neutral or "neutral within technology classes" with bonus-credit structures for U.S.-content, prevailing wage, and energy-community siting.
Defenders argue subsidies catalyze private investment and rebuild U.S. manufacturing. Critics argue they pick winners, distort markets, and cost more than carbon-pricing alternatives.
