How Biden’s Sustainable Aviation Fuel Tax Credits Will Work

On the future of flying, efficient water heaters, and data centers

How Biden’s Sustainable Aviation Fuel Tax Credits Will Work

Current conditions: It will be 107 degrees Fahrenheit in Kolkata as Southeast Asia’s heat wave continues • Kansas and Oklahoma are on alert for tornadoes and large hail • The Eta Aquariids meteor shower peaks this week.

THE TOP FIVE

1. Biden administration outlines rules for sustainable aviation fuel subsidies

The Treasury Department and IRS yesterday released new details about the subsidy program for producers of sustainable aviation fuel (SAF), which the Biden administration hopes will help cut emissions from the aviation industry while also supporting farmers. What makes SAF “sustainable” is that it comes from biomass (stuff like corn grain, wood mill waste, even manure) instead of petroleum. Burning SAFs for fuel still produces carbon dioxide, but their lifecycle emissions are lower than those of fossil fuels, and they can be used in existing planes, so they are seen as a quick way to cut aviation emissions in the short term.

Under the new guidance, refiners will be eligible for a credit of $1.25 per gallon if their fuel reduces greenhouse gas emissions by 50% compared to traditional jet fuel, and up to $1.75 per gallon if emissions cuts go beyond 50%. The announcement clarified that SAF made out of ethanol is eligible if corn farmers use “climate smart agriculture” such as cover cropping, no-till, and efficient fertilizer application to keep carbon in the soil. Reaction to the announcement has been mixed. Ethanol trade groups were pleased to be included but annoyed at the stringent farming requirements. Environmental groups worry crop-based biofuels will take up too much farmland and could lead to deforestation. “Powering planes with crop-based biofuels is anything but sustainable,” said Dan Lashof, director of the World Resources Institute. Commercial aviation accounts for 2% of U.S. carbon emissions.

2. DOE finalizes water heater efficiency standards

More news from the government yesterday: The Department of Energy announced that most new electric water heaters will have to run on heat pump technology starting in 2029. Water heaters are some of the biggest energy hogs in the average American home. Making them more efficient could reduce consumers’ utility bills by approximately $100 per year, the DOE said. And the energy savings of the new standards are quite astonishing: 17.6 quadrillion British thermal units over 30 years of shipments, “the largest savings ever from a single DOE efficiency standard, representing more than the energy use of the entire U.S. residential building sector in a single year.” As for the climate, the DOE said the efficiency standards will reduce greenhouse gas emissions by 2.5 billion metric tons over 30 years, which is roughly equivalent to taking 18 million gas-powered cars off the road.

3. Microsoft teams up with Brookfield to power data centers with clean energy

Microsoft is throwing significant financial backing behind renewable energy projects to be developed by Brookfield Asset Management that will help power data centers, the Financial Times reported. The wind and solar projects will be built between 2026 and 2030, and have at least 10.5 gigawatts of generating capacity, or enough to power 1.8 million homes. The tech giant will back the projects’ development to the tune of about $10 billion, “in a deal that underscores the race to meet clean energy commitments while satisfying the voracious energy demand of cloud computing and artificial intelligence,” the FT added.

4. Internal documents offer insight into fossil fuel companies’ climate strategies

Congressional Democrats released documents they say reveal how big oil companies have misled the public about their role in causing and fixing the climate crisis. The documents include internal communications from companies like Exxon, Chevron, Shell, and BP. In the exchanges, company representatives cast doubt on the feasibility of limiting global warming to 1.5 degrees Celsius, dismiss the idea that the Paris Agreement should be cause for changing course on fossil fuel production, and acknowledge the huge climate-warming potential of methane. “For decades, the fossil-fuel industry has known about the economic and climate harms of its products but has deceived the American public to keep collecting more than $600 billion each year in subsidies while raking in record-breaking profits,” said Democratic Sen. Sheldon Whitehouse, who chairs the Senate Budget Committee. The committee will hold a hearing on the subject today.

5. Tesla shares dip after Supercharger layoffs

Tesla shares are down by about 5% this morning following news that the company slashed its entire Supercharging unit. Sources told Electrek that Tesla has already pulled out of four leases on planned Supercharger locations in New York. CEO Elon Musk also confirmed on X that the company will slow construction of new charging stations.

Lala Lashes Hawaii

On the battery backlog, Canadian U, and Peter Thiel goes gas gaucho

Current conditions: Floodwaters swept through eastern Iowa, swelling the White River to its highest level in 113 years • A southwest monsoon, or hagabat, has capped off several weeks of storms in the Philippines that, combined, killed nearly two dozen people • Temperatures in Madrid are lingering near 100 degrees Fahrenheit until midweek, when the Spanish capital will cool off into the high 80s; the Greek capital of Athens, meanwhile, is bracing for the exact reverse.


THE TOP FIVE

1. Tropical Storm Lala leaves 200,000 without electricity in Hawaii

Tropical storms almost never hit the Hawaiian islands directly. The last time a tropical system struck the archipelago was in 2018, when Tropical Storm Olivia made landfall over Maui. It was, per CTV News, the first time a storm had come ashore like that since records began in the 1950s. The last full-blown hurricane to strike the state was in 1992, when Category 4 Iniki landed on Kauai, the chain’s northernmost island, as the strongest storm on record to hit the state. But the Big Island hadn’t seen a major storm make landfall since 1900. So Tropical Storm Lala, by some measures a Category 1 hurricane, left a mark. Nearly 200,000 homes and businesses — representing roughly 70% of the Big Island — remained without electricity on Sunday night as winds of up to 75 miles per hour and floodwaters hammered the state’s infrastructure. “Customers should prepare for extended outages lasting weeks or even months in the hardest hit rural areas of Hawaii island,” Hawaiian Electric, the utility that serves 95% of the state, told the Honolulu Star-Advertiser.

How a Rhode Island Mayoral Race Became a Referendum on Climate Policy

In Providence, at least, climate change is still on the ballot.

Here’s some trivia for you: What was the first state to see its average temperature break the 2-degree Celsius threshold for warming above pre-industrial levels? It wasn’t Alaska, the fastest-warming state, nor was it California or Florida, states with some of the most visible impacts of the extreme weather crisis. It was not Arizona or Texas, either, though “hot” and “warming” are often conflated.

The answer, in fact, is humble Rhode Island, which passed the international benchmark for accelerated climatic impacts back in 2019. It is perhaps less surprising, then, to learn that in the Ocean State’s largest city, Providence, climate change and how to adapt to it have become one of the central talking points in a heated mayoral race, which in the deep-blue city is likely to culminate in the September 9 primary.

How an ‘Abundance’ Policy Shop Is Approaching Data Centers

Chatting about win-win solutions with the Abundance Institute’s Ryan Norris.

This week’s conversation is with Ryan Norris, senior fellow for energy policy at the Abundance Institute. The libertarian-leaning institute — whose name cleverly shortens to AI — is a new-ish entity with increasing relevance in energy and tech spaces. As Norris and I discussed, it’s starting to help shape policy on data center development and the generation that’ll power it all, especially in Republican circles. Norris himself previously worked with Americans for Prosperity, a right-wing political organization. I reached out to him and asked if we could chat because I wanted to know more about the institute’s work within the energy space. He wound up saying a lot more than I expected. So let’s dive into it.

The following conversation was lightly edited and abridged for clarity.
