WASHINGTON (Reuters) -The U.S. Senate's proposed cuts to clean energy subsidies in its version of President Donald Trump's tax and spending bill have drawn searing criticism from business and labor groups since they were unveiled over the weekend, with some arguing the moves will raise power prices and kill jobs.

The pushback, which includes a swipe from Trump ally and Tesla CEO Elon Musk, comes as senators started voting on a potentially long list of amendments to the bill on Monday morning, giving renewable energy advocates on both sides of the political spectrum a last window to push for changes.

"Taxing energy production is never good policy, whether oil & gas or, in this case, renewables," said Neil Bradley, policy director of the U.S. Chamber of Commerce, in a post on X over the weekend. "Electricity demand is set to see enormous growth & this tax will increase prices. It should be removed."

"This would be incredibly destructive to America!" Musk posted on X, saying the cuts could endanger the development of energy-hungry artificial intelligence technology, among other things.

Trump has said he intends to maximize U.S. energy production, with a focus on fossil fuels, in part to ensure the power industry can supply the AI industry's growth. But he has also promised to wipe out subsidies for renewables.

The Senate bill would roll back incentives for wind, solar, batteries and other clean energy technologies created by President Joe Biden's 2022 Inflation Reduction Act, and add a new tax on these projects if they cannot prove their products are made without Chinese parts.

Those provisions were harsher on the credits than the previous Senate version and even the House version.

Sean McGarvey, president of the North America's Building Trades Unions (NABTU), which represents over 3 million construction workers, blasted the bill's impact on jobs.

"If enacted, this stands to be the biggest job-killing bill in the history of this country. Simply put, it is the equivalent of terminating more than 1,000 Keystone XL pipeline projects," he said in a statement, referring to an oil pipeline project blocked by Biden's administration.

Republican Senator Thom Tillis of North Carolina, one of two Republicans who voted against advancing the bill, also blasted the bill on the Senate floor overnight and warned that it will cause power shortages by hamstringing renewable energy and battery storage.

Tillis drew ire from Trump for voting against the motion to advance the bill and has since said he does not plan to run for re-election.

"What you have done is create a blip in power service, because there isn't going to be a gas-fired generator anytime soon," he said on the floor.

Tillis had worked as a consultant covering the utility industry and said the bill ignores the reality of the soaring demand for power by data centers.

Brian Schatz, a Democratic Senator from Hawaii, also railed against the bill's impact.

"This bill will increase prices. The 500-GW less energy in the next decade is pretty much exactly the amount we will need to meet rising demand," he said. 

"You don't have to love clean energy or be an environmentalist to understand that this is a basic question of supply and demand," he said.
