A new report concludes that federal investment grew clean energy jobs in the last year as more than two-thirds of states clamored to develop projects. Pennsylvania rounds out the top 10 states that offer the most clean energy jobs, according to an analysis from E2 released Monday that examined how the Inflation Reduction Act spurred expansion in the sector. Despite this, the bulk of investment spreads across the Southeast and Midwest, the report showed. The federal law directs the U.S. Department of Energy to spend $400 billion on subsidies, grants and loan guarantees for clean energy development across the country.
