"The Inflation Reduction Act calls for spending less than $500 billion over a decade, compared with the American Rescue Plan’s $1.9 trillion in a single year . . . . But if the spending isn’t very large, how can it have such a big impact? The answer is that right now we’re sitting on a sort of cusp. Renewable energy technology has made revolutionary progress, and renewables are already cheaper in many areas than fossil fuels. A moderate push from public policy is all that it will take to transition to a much greener economy. And the Inflation Reduction Act will provide that push."
