Democrats and clean energy advocates are ratcheting up pressure on a handful of Republican senators to salvage billions of dollars in projects, ahead of an expected vote next week on President Trump’s megabill that targets critical subsidies for elimination.

A proposal by Senate Republicans would adjust the pace at which some crucial home energy efficiency and electric vehicle tax credits are phased out in timelines different from what House Republicans proposed in the multitrillion-dollar tax bill they passed last month.

A Senate tax package softens some blows imposed on renewables by a House version of the bill. But it still terminates many credits for clean power.
