Some of the arguments will ring a bell to anyone who’s been following fights against renewables.
Indiana has power. Indiana has transmission. Indiana has a business-friendly Republican government. Indiana is close to Chicago but — crucially — not in Illinois. All of this has led to a huge surge of data center development in the “Crossroads of America.” It has also led to an upswell of local opposition.
There are almost 30 active data center proposals in Indiana, plus five that have already been rejected in the past year, according to data collected by the environmentalist group Citizens Action Coalition. Google, Amazon, and Meta have all announced projects in the state since the beginning of 2024.
Nipsco, one of the state’s utilities, has projected 2,600 megawatts worth of new load by the middle of the next decade as its base scenario, mostly attributable to “large economic development projects.” In a more aggressive scenario, it sees 3,200 megawatts of new load — that’s three large nuclear reactors’ worth — by 2028 and 8,600 megawatts by 2035. While short of, say, the almost 36,500 megawatts worth of load growth planned in Georgia for the next decade, it’s still a vast range of outcomes that requires some kind of advanced planning.
That new electricity consumption will likely be powered by fossil fuels. Projected load growth in the state has extended a lifeline to Indiana’s coal-fired power plants, with retirement dates for some of the fleet being pushed out to late in the 2030s. It’s also created a market for new natural gas-fired plants that utilities say are necessary to power the expected new load.
State and local political leaders have greeted these new data center projects with enthusiasm, Ben Inskeep, the program director at CAC, told me. “Economic development is king here,” he said. “That is what all the politicians and regulators say their number one concern is: attracting economic development.”
This can sometimes mean policies to support data center development that CAC describes as giveaways, such as utility customers having to cover the bill for transmission upgrades and a 50-year sales tax exemption specifically for data centers. It’s all in the name of economic development and job growth, but that comes at “the detriment of ratepayers and taxpayers,” Inskeep told me.
Take that sales tax exemption: A 1,000 megawatt data center might face $500 million in annual electricity costs, Inskeep told me. “If they’re not having to pay that 7% sales tax on half a billion dollars, times 50 years, we’re talking about $1.7 billion per data center in sales tax exemption, just on the electricity portion of their bill,” Inskeep said.
Even that $500 million is not guaranteed. The minimum payment for such a data center has to pay is $332 million — having been doubled from just $173 million after CAC petitioned for an increase. Ratepayer advocates celebrated the settlement because it guaranteed that large data centers would pay for some of the costs they impose on the whole electrical system, even if their actual consumption is not as high as forecast.
Indiana is “an ideal jurisdiction for data center siting given its physical advantages such as available land, access to grid transmission, water, fiber optic cables, proximity to population centers,” Mizuho Securities analyst Gabriel Moreen wrote in a note to clients. “The state has demonstrated a political and economic receptivity to data centers, such as tax incentives for building data centers and political support at local and state levels.”
But cracks in that edifice of political support may be beginning to show. While data center development has substantial support from the state government — a bill tospeed up regulatory approvals for data centers and the generation to serve them is on Governor Mike Braun’s desk after a party-line statehouse vote — projects are also being withdrawn in the face of popular outrage.
Earlier this month, county commissioners in Kosciusko County rejected a rezoning proposition that would have been necessary for a data center project on rural land near Leesburg after a number of local residents spoke out against it. Before that, the city of Valparaiso rejected a data center project in March, following a city council meeting where residents complained about “ noise, power and water consumption and the impact on property values,” according to Lakeshore Public Media.
The objections in Kosciusko County and across the state will not be unfamiliar to anyone with experience in large scale development — residents don’t like noise; they worry that the projects will lead to higher electricity costs across the board; they’re skeptical of the job benefits; they think the developers are getting taxpayer giveaways; they don’t want to see agricultural land converted for the sake of industry.
“That’s a big red flag for a lot of local governments where they’re a bit more skeptical of those types of development,” Inskeep told me.
Of course, these objections will be familiar to anyone who follows local opposition to renewable power developments like wind and solar, which regularly draw on farm land, noise, and skepticism of promised economic benefits.
And just like with solar and wind, these local objections could be slowing a projected build out that many analysts simply assume will follow an exponential path — which would, ironically, put a dent in the demand growth that many energy developers, renewable or not, are hoping to ride to more profits.
But at the local level, for activists, the fight happens one project at a time, Inskeep told me.
“We’re building out tools to help local folks feel like they have the knowledge and the resources to be able to engage at these local levels. Because when we have several dozen data center proposals in the state of Indiana and more coming, a small organization like ours can’t be there for each individual fight,” Inskeep said.

On the budget debate, MethaneSAT’s untimely demise, and Nvidia
Current conditions: The northwestern U.S. faces “above average significant wildfire potential” for July • A month’s worth of rain fell over just 12 hours in China’s Hubei province, forcing evacuations • The top floor of the Eiffel Tower is closed today due to extreme heat.
The Senate finally passed its version of Trump’s One Big Beautiful Bill Act Tuesday morning, sending the tax package back to the House in hopes of delivering it to Trump by the July 4 holiday. The excise tax on renewables that had been stuffed into the bill over the weekend was removed after Senator Lisa Murkowski of Alaska struck a deal with the Senate leadership designed to secure her vote. In her piece examining exactly what’s in the bill, Heatmap’s Emily Pontecorvo explains that even without the excise tax, the bill would “gum up the works for clean energy projects across the spectrum due to new phase-out schedules for tax credits and fast-approaching deadlines to meet complex foreign sourcing rules.” Debate on the legislation begins on the House floor today. House Speaker Mike Johnson has said he doesn’t like the legislation, and a handful of other Republicans have already signaled they won’t vote for it.
The Environmental Protection Agency this week sent the White House a proposal that is expected to severely weaken the federal government’s ability to rein in planet-warming pollution. Details of the proposal, titled “Greenhouse Gas Endangerment Finding and Motor Vehicle Reconsideration,” aren’t clear yet, but EPA Administrator Lee Zeldin has reportedly been urging the Trump administration to repeal the 2009 “endangerment finding,” which explicitly identified greenhouse gases as a public health threat and gave the EPA the authority to regulate them. Striking down that finding would “free EPA from the legal obligation to regulate climate pollution from most sources, including power plants, cars and trucks, and virtually any other source,” wrote Alex Guillén at Politico. The title of the proposal suggests it aims to roll back EPA tailpipe emissions standards, as well.

So long, MethaneSAT, we hardly knew ye. The Environmental Defense Fund said Tuesday that it had lost contact with its $88 million methane-detecting satellite, and that the spacecraft was “likely not recoverable.” The team is still trying to figure out exactly what happened. MethaneSAT launched into orbit last March and was collecting data about methane pollution from global fossil fuel infrastructure. “Thanks to MethaneSAT, we have gained critical insight about the distribution and volume of methane being released from oil and gas production areas,” EDF said. “We have also developed an unprecedented capability to interpret the measurements from space and translate them into volumes of methane released. This capacity will be valuable to other missions.“ The good news is that MethaneSAT was far from the only methane-tracking satellite in orbit.
Nvidia is backing a D.C.-based startup called Emerald AI that “enables AI data centers to flexibly adjust their power consumption from the electricity grid on demand.” Its goal is to make the grid more reliable while still meeting the growing energy demands of AI computing. The startup emerged from stealth this week with a $24.5 million seed round led by Radical Ventures and including funding from Nvidia. Emerald AI’s platform “acts as a smart mediator between the grid and a data center,” Nvidia explains. A field test of the software during a grid stress event in Phoenix, Arizona, demonstrated a 25% reduction in the energy consumption of AI workloads over three hours. “Renewable energy, which is intermittent and variable, is easier to add to a grid if that grid has lots of shock absorbers that can shift with changes in power supply,” said Ayse Coskun, Emerald AI’s chief scientist and a professor at Boston University. “Data centers can become some of those shock absorbers.”
In case you missed it: California Governor Gavin Newsom on Monday rolled back the state’s landmark Environmental Quality Act. The law, which had been in place since 1970, required environmental reviews for construction projects and had become a target for those looking to alleviate the state’s housing crisis. The change “means most urban developers will no longer have to study, predict, and mitigate the ways that new housing might affect local traffic, air pollution, flora and fauna, noise levels, groundwater quality, and objects of historic or archeological significance,” explainedCal Matters. On the other hand, it could also mean that much-needed housing projects get approved more quickly.
Tesla is expected to report its Q2 deliveries today, and analysts are projecting a year-over-year drop somewhere from 11% to 13%.
Jesse teaches Rob the basics of energy, power, and what it all has to do with the grid.
What is the difference between energy and power? How does the power grid work? And what’s the difference between a megawatt and a megawatt-hour?
On this week’s episode, we answer those questions and many, many more. This is the start of a new series: Shift Key Summer School. It’s a series of introductory “lecture conversations” meant to cover the basics of energy and the power grid for listeners of every experience level and background. In less than an hour, we try to get you up to speed on how to think about energy, power, horsepower, volts, amps, and what uses (approximately) 1 watt-hour, 1 kilowatt-hour, 1 megawatt-hour, and 1 gigawatt-hour.
Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Jesse Jenkins: Let’s start with the joule. The joule is the SI unit for both work and energy. And the basic definition of energy is the ability to do work — not work in a job, but like work in the physics sense, meaning we are moving or displacing an object around. So a joule is defined as 1 newton-meter, among other things. It has an electrical equivalent, too. A newton is a unit of force, and force is accelerating a mass, from basic physics, over some distance in this case. So 1 meter of distance.
So we can break that down further, right? And we can describe the newton as 1 kilogram accelerated at 1 meter per second, squared. And then the work part is over a distance of one meter. So that kind of gives us a sense of something you feel. A kilogram, right, that’s 2.2 pounds. I don’t know, it’s like … I’m trying to think of something in my life that weighs a kilogram. Rob, can you think of something? A couple pounds of food, I guess. A liter of water weighs a kilogram by definition, as well. So if you’ve got like a liter bottle of soda, there’s your kilogram.
Then I want to move it over a meter. So I have a distance I’m displacing it. And then the question is, how fast do I want to do that? How quickly do I want to accelerate that movement? And that’s the acceleration part. And so from there, you kind of get a physical sense of this. If something requires more energy, if I’m moving more mass around, or if I’m moving that mass over a longer distance — 1 meter versus 100 meters versus a kilometer, right? — or if I want to accelerate that mass faster over that distance, so zero to 60 in three seconds versus zero to 60 in 10 seconds in your car, that’s going to take more energy.
Robinson Meyer: I am looking up what weighs … Oh, here we go: A 13-inch MacBook Air weighs about, a little more than a kilogram.
Jenkins: So your laptop. If you want to throw your laptop over a meter, accelerating at a pace of 1 meter per second, squared …
Meyer: That’s about a joule.
Jenkins: … that’s about a joule.

If the Senate reconciliation bill gets enacted as written, you’ve got about 92 days left to seal the deal.
If you were thinking about buying or leasing an electric vehicle at some point, you should probably get on it like, right now. Because while it is not guaranteed that the House will approve the budget reconciliation bill that cleared the Senate Tuesday, it is highly likely. Assuming the bill as it’s currently written becomes law, EV tax credits will be gone as of October 1.
The Senate bill guts the subsidies for consumer purchases of electric vehicles, a longstanding goal of the Trump administration. Specifically, it would scrap the 30D tax credit by September 30 of this year, a harsher cut-off than the version of the bill that passed the House, which would have axed the credit by the end of 2025 except for automakers that had sold fewer than 200,000 electric vehicles. The credit as it exists now is worth up to $7,500 for cars with an MSRP below $55,000 (and trucks and sports utility vehicles under $80,000), and, under the Inflation Reduction Act, would have lasted through the end of 2032. The Senate bill also axes the $4,000 used EV tax credit at the end of September.
“Long story short, the credits under the current legislation are only going to be on the books through the end of September,” Corey Cantor, the research director of the Zero Emission Transportation Association, told me. “Now is definitely a good time, if you’re interested in an EV, to look at the market.”
The Senate applied the same strict timeline to credits for clean commercial vehicles, both new and used. For home EV chargers, the tax credit will now expire at the end of June next year.
While EVs were on the road well before the 2022 passage of the Inflation Reduction Act, what the new tax credit did was help build out a truly domestic electric vehicle market, Cantor said. “You have a bunch of refreshed EV models from major automakers,” Cantor told me, including “more affordable models in different segments, and many of them qualify for the credit.”
These include cars produceddomestically by Kia,Hyundai, and Chevrolet. But of course, the biggest winner from the credit is Tesla, whose Model Y was the best-selling car in the world in 2023.
Tesla shares were down over 5.5% in Tuesday afternoon trading, though not just because of Congress. JPMorgan also released an analyst report Monday arguing that the decline in sales seen in the first quarter would accelerate in the second quarter. President Trump, with whom Tesla CEO Elon Musk had an extremely public falling out last month, suggested on social media Monday night that the government efficiency department Musk himself formerly led should “take a good, hard, look” at the subsidies Musk receives across his many businesses. Trump also said that he would “take a look” at Musk’s United States citizenship in response to reporters’ questions about it.
Cantor told me that he expects a surge of consumer attention to the EV market if the bill passes in its current form. “You’ve seen more customers pull their purchase ahead” when subsidies cut-offs are imminent, he said.
But overall, the end of the subsidy is likely to reduce EV sales from their previously expected levels.
Harvard researchers have estimated that the termination of the EV tax credit “would cut the EV share of new vehicle sales in 2030 by 6.0 percentage points,” from 48% of new sales by 2030 to 42%. Combined with other Trump initiatives such as terminating the National Electric Vehicle Infrastructure program for publicly funded chargers (currently being litigated) and eliminating California’s waiver under the Clean Air Act that allowed it to set tighter vehicle emissions standards, the share of new car sales that are electric could fall to 32% in 2030.
But not all government support for electric vehicles will end by October 1, even if the bill gets the president’s signature in its current form.
“It’s important for consumers to know there are many states that offer subsidies, such as New York, and Colorado,” Cantor told me. That also goes for California, New Jersey, Nevada, and New Mexico. You can find the full list here.
