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

A Republican plan heading to a vote in the Senate would quickly end incentives for clean energy and impose new taxes on some wind and solar projects, while boosting production of coal used to make steel.

Tucked inside Republicans' massive domestic policy bill is an excise tax for wind and solar projects, a provision that came as a surprise not just to the renewable energy industry, but to numerous senators who are crafting the legislation.
