The Congressional Budget Office, as well as third-party groups like the Tax Foundation and the Penn Wharton Budget Model, have estimated that an extension of the 2017 tax cuts would cost between $3.7 and $4.5 trillion through 2034. If all of Trump’s additional proposed tax cuts were enacted, the cost would jump to $6.8 trillion, according to Penn Wharton. Congress is still at the beginning of the reconciliation process. The next step is for the House and Senate to negotiate a topline number and issue instructions to the committees that will write the final bill on the levels of spending they’re allowed to include.
As Heatmap’s Emily Pontecorvo and Jael Holzman explain, the dollar amount assigned to each committee is a ceiling, and it’s calculated on a net basis. So if the Ways and Means committee, which oversees tax legislation, is assigned a $4.5 trillion deficit ceiling, as it was in the version of the reconciliation instructions that recently passed the House, it’s going to have to find several trillion dollars worth of spending programs to cut. Fully repealing the Inflation Reduction Act’s green energy tax credits — which, according to new modeling from the nonpartisan Tax Foundation, would raise about $850 billion — will start to look harder to avoid.
2. Carolina wildfires hit areas damaged by Hurricane Helene
Major wildfires erupted in the Carolinas over the weekend, burning more than 4,000 acres and threatening some areas that were hit hard by Hurricane Helene six months ago. Debris from hurricanes makes already battered areas more vulnerable to fires, Colleen Hagerty wrote for Heatmap in the aftermath of Helene. And as Heatmap’s Jeva Lange wrote more recently, researchers are pointing to the South as a new area of wildfire concern.
South Carolina’s governor declared a state of emergency Saturday as the Table Rock fire spread to cover 300 acres in the Blue Ridge Mountains, prompting evacuations. In North Carolina, several large fires are raging out of control in Polk County, southeast of Ashville, where last year’s Hurricane Helene brought devastating floods and debris. Much of Polk County is enduring drought conditions. High winds, dry vegetation, and low humidity are fueling the fires, but response efforts are also hampered by steep terrain and hurricane debris that has yet to be cleared. Mandatory evacuations were in effect for some parts of Polk County.

3. IEA: Extreme temperatures boosted 2024 global energy demand
Global energy demand rose by 2.2% last year, faster than the average pace seen over the past decade or so, according to the International Energy Agency’s Global Energy Review 2025 report. The rise was led mostly by the power sector as record warmth meant greater need for air conditioning, especially in emerging and developing countries. “Nearly all of the rise in electricity demand was met by low-emissions sources,” the report said, with renewables and nuclear providing 80% of the growth in global electricity generation. Energy-related carbon dioxide emissions rose last year (by 0.8%) but at a slower rate than in 2023. “The global increase of 300 million tonnes of CO2 was influenced by record high temperatures,” the report said. “If weather in 2024 had remained consistent with 2023, itself the second-hottest year on record, about half of the increase in global emissions would have been avoided.”
4. Sierra Club list shows which grants the EPA canceled
In case you missed it: We now know which grants the Environmental Protection Agency has canceled. A document the EPA shared with the Sierra Club in response to a Freedom of Information Act request shows 49 individual grants that were either “canceled” or prevented from being awarded from January 20 through March 7. The grants’ total cumulative value is more than $230 million, although some $30 million appears to have already been paid out to recipients. Nearly half of the canceled grants are related to environmental justice initiatives. Here’s the full list of grants, by program.
5. Study finds that political ideology still drives EV adoption
A new study finds that political views remain a key factor in determining whether someone chooses to buy an electric vehicle. The report, from the National Bureau of Economic Research, examined new EV registration data at a county level between 2012 and 2023 and found that during those years, the scale of the EV market expanded, yet nearly half of all sales were in the 10% most Democratic counties. Researchers controlled for other factors, such as income and gas prices, and still, the strong correlation between political ideology and EV adoption remains. And it hasn’t decreased over time. “We find little evidence that the U.S. EV market has broadened across the political spectrum from 2012 to 2023,” the researchers say. There were some exceptions, though: EV trucks and vans are “significantly less concentrated” in left-leaning counties compared to electric cars and SUVs.
THE KICKER
California now has nearly 50% more EV chargers than it does gas pumps. According to the California Energy Commission, there are roughly 178,000 EV chargers in the state, compared with approximately 120,000 gas nozzles.
