Private investment in clean energy projects like solar panels, hydrogen power and electric vehicles surged after President Biden signed an expansive climate bill into law last year, a development that shows how tax incentives and federal subsidies have helped reshape some consumer and corporate spending in the United States.

New data being released on Wednesday suggest the climate law and other parts of Mr. Biden’s economic agenda have helped speed the development of automotive supply chains in the American Southwest, buttressing traditional auto manufacturing centers in the industrial Midwest and the Southeast. The 2022 law, which passed with only Democratic support, aided factory investment in conservative bastions like Tennessee and the swing states of Michigan and Nevada. The law also helped underwrite a spending spree on electric cars and home solar panels in California, Arizona and Florida.
