A Republican-backed spending bill passed by the Senate has raised concerns about the future of renewable energy projects in the US. While a proposed excise tax on solar and wind projects was ultimately removed, the bill includes provisions that could make it significantly harder for these projects to qualify for tax incentives established in 2022. This outcome follows a lengthy "vote-a-rama" session and leaves the fate of many renewable energy initiatives, particularly those in Republican-held districts, uncertain. Industry groups fear the new restrictions could hinder growth and investment in the sector.
