Senate Republicans have quietly inserted provisions in President Donald Trump’s domestic policy bill that would not only end federal support for wind and solar energy but would impose an entirely new tax on future projects,

Wind and solar companies were already bracing for Congress to end federal subsidies. But the Senate bill goes even further and penalizes those industries.

The latest version of the Senate’s massive budget bill that is being raced through for a vote as soon as Saturday deals a fatal blow to the use of tax credits in place since 2005 to spur more wind and solar energy and would set a new tax on those projects for the first time, renewable energy proponents said on Saturday.
