The focus on energy comes after weeks of debate over Biden-era energy credits.

The initial Senate blueprint had offered a slower rollback of clean energy credits for things like solar panels and electric vehicles but last minute changes to the bill put it more in line with the harder line House version which seeks to eliminate the credits sooner.

Some provisions are even more immediate with the Senate version proposing to eliminate EV credits by September 30 of this year.

And on top of that, a new tax was unveiled when the bill was released that would not just eliminate government help for renewable energy projects — but add a new cost for wind and solar projects completed after 2027 if a certain amount of supplies came from China.

The changes stunned many clean energy advocates — not just Musk — with a statement from the American Clean Power Association saying the effect would be to “strand hundreds of billions of dollars in current investments.”

What that could means for consumers down the road — some concluded — are higher utility bills as currently under construction AI data centers are set to increase electricity demand in the years ahead.

Some are even projecting double digit price increases in some utility bills by 2029.

An analysis from the left-leaning Center for American Progress found that the bill would exacerbate existing upward pressure on utility prices, with Democratic Senator Brian Schatz adding “we are literally going to have not enough electricity because Trump is killing solar.”

Fossil fuels advocates meanwhile were largely ebullient at the last minute changes which saw existing fossil fuel focused provisions — around issues like permitting, lease sales, and methane emissions fees — joined by some new credits for these producers including for coal.

Senate Republicans say the bill will generate over $15 billion in new federal revenue through expanded oil, gas, and coal leasing with leaders with Senator John Barasso of Wyoming saying “America is an energy superpower and once again, we are going to act like it.”

The bill is also set to be even more expensive after weeks of negotiations saw expensive compromises on issues like state and local tax (SALT) deductions, more generous business tax credits, and the adjustment of some cost savings around Medicaid.

The fullest accounting came over the weekend when the CBO estimated the Senate bill would increase the debt by nearly $3.3 trillion from 2025 to 2034.

The analysis also found that 11.8 million additional Americans would become uninsured by 2034 because of the health care provisions — an increase over the findings for the House-passed version that tallied that 10.9 million people would be without health coverage of that version passed.

The bill is projected to be even more expensive after things like interest costs are included, with the Committee for a Responsible Federal Budget protecting the current total tally as in the neighborhood of $3.5 to $4.2 trillion over the next decade.

“The debt impact could rise as high as $4.5 trillion if various rumored adjustments are made,” the group added of potential additional changes still to come.

The findings also come as Senate Republicans push forward on a budget gimmick that is set to hide $3.8 trillion in red ink using a “current policy baseline” that Democrats say violated Senate rules but appears set to proceed.

Either way the sky-high debt findings could imperil the bill politically, with two GOP senators already likely to vote no and others not yet saying they will back Trump’s effort to get this over the line in the coming hours.

The bill will also need to be approved by the House if the amended package advances and is then considered by a bloc of fiscal conservatives there who say they barely voted in May for that less expensive version.

One initial comment from the House Freedom Caucus was negative, with the group writing that the new tally was above “our agreed budget framework.”
