On Tuesday, the Senate Finance Committee proposed speeding up the elimination of tax credits for solar and wind energy. Under current law, these do not expire until 2032; under the new proposal, they would be reduced by 60% next year and phased out entirely in 2028.

Outside the US Capitol on Tuesday, solar energy industry advocates held a rally regarding the changes to mega bill. According to the Senate text, it proposes a phase out of solar and wind energy tax credits by 2028 but extend the incentives for hydro power, nuclear and geothermal energy to 2036.

The Senate’s tax bill would boost baseload electricity — including nuclear and geothermal power — while slashing incentives for intermittent sources.

The House version of the bill, which passed in late May, removed nearly all the federal clean energy tax credits over the next few years, in the name of reducing the deficit, repealing “Green New Deal” policies and leveling the playing field for nuclear and fossil fuel development.
