Passed in 2022, the IRA represents the most significant government climate investment in U.S. history, earmarking $369 billion for clean energy. 'The goal, reducing greenhouse gasses by 40 percent below 2005 levels by 2030, requires major capital expenditures on solar and wind, electrical vehicles and related infrastructure,' says Quinlan. The bill also includes a slew of tax credits and other incentives for businesses and consumers to invest in energy-efficient technologies and equipment.
