This vast 1.3 GW Indiana solar farm will power 200,000 homes
Mammoth Solar, a 1.3 gigawatt (GW) solar farm in northern Indiana, is now powering into its biggest construction phase yet, cementing its place as one of the largest solar projects in the US.
The solar farm is set to increase Indiana’s solar capacity by more than 20% once it’s fully online. And with construction ramping up this month, developer Doral Renewables has given Bechtel Full Notice to Proceed on the design, engineering, and construction of three major phases of the project: Mammoth South, Mammoth Central I, and Mammoth Central II. Together, these phases will generate 900 MW of clean energy.
That’s enough electricity to power around 200,000 homes with clean energy, helping Indiana shift away from fossil fuels while boosting the local economy.
Construction is already underway, and over the next two years, Bechtel will install around 2 million solar panels, with about half of them made in the US. The company is also handling all engineering, procurement, and construction work, using its digital project management tools and autonomous tech to keep everything on track.
At the peak of the buildout, Mammoth Solar is expected to create over 1,200 jobs, with at least 15% of those set aside for apprenticeships.
Bechtel says its success will hinge on strong collaboration with local trades and vendors. The company is working closely with craft professionals and is committed to being a reliable community partner throughout construction.
Once the solar farm is complete in 2027, Doral Renewables plans to roll out agrivoltaics across the site. That means livestock grazing and crop cultivation will happen right alongside energy production, giving farmers in the area a way to keep working their land while supporting clean energy development.

Trump wants coal to power AI data centers. The tech industry may need to make peace with that for now
President Donald Trump wants to revive the struggling coal industry in the U.S. by deploying plants to power the data centers that the Big Tech companies are building to train artificial intelligence.
Trump issued an executive order in April that directed his Cabinet to find areas of the U.S. where coal-powered infrastructure is available to support AI data centers and determine whether the infrastructure can be expanded to meet the growing electricity demand from the nation’s tech sector.
Trump has repeatedly promoted coal as power source for data centers. The president told the World Economic Forum in January that he would approve power plants for AI through emergency declaration, calling on the tech companies to use coal as a backup power source.
“They can fuel it with anything they want, and they may have coal as a backup — good, clean coal,” the president said.
Trump’s push to deploy coal runs afoul of the tech companies’ environmental goals. In the short-term, the industry’s power needs may inadvertently be extending the life of existing coal plants.
Coal produces more carbon dioxide emissions per kilowatt hour of power than any other energy source in the U.S. with the exception of oil, according to the Energy Information Administration. The tech industry has invested billions of dollars to expand renewable energy and is increasingly turning to nuclear power as a way to meet its growing electricity demand while trying to reduce carbon dioxide emissions that fuel climate change.
For coal miners, Trump’s push is a potential lifeline. The industry has been in decline as coal plants are being retired in the U.S. About 16% of U.S. electricity generation came from burning coal in 2023, down from 51% in 2001, according to EIA data.
Peabody Energy CEO James Grech, who attended Trump’s executive order ceremony at the White House, said “coal plants can shoulder a heavier load of meeting U.S. generation demands, including multiple years of data center growth.” Peabody is one of the largest coal producers in the U.S.
Grech said coal plants should ramp up how much power they dispatch. The nation’s coal fleet is dispatching about 42% of its maximum capacity right now, compared to a historical average of 72%, the CEO told analysts on the company’s May 6 earnings call.
“We believe that all coal-powered generators need to defer U.S. coal plant retirements as the situation on the ground has clearly changed,” Grech said. “We believe generators should un-retire coal plants that have recently been mothballed.”
Tech sector reaction
There is a growing acknowledgment within the tech industry that fossil fuel generation will be needed to help meet the electricity demand from AI. But the focus is on natural gas, which emits less half the CO2 of coal per kilowatt hour of power, according the the EIA.
“To have the energy we need for the grid, it’s going to take an all of the above approach for a period of time,” Kevin Miller, Amazon’s vice president of global data centers, said during a panel discussion at conference of tech and oil and gas executives in Oklahoma City last month.
“We’re not surprised by the fact that we’re going to need to add some thermal generation to meet the needs in the short term,” Miller said.
Thermal generation is a code word for gas, said Nat Sahlstrom, chief energy officer at Tract, a Denver-based company that secures land, infrastructure and power resources for data centers. Sahlstrom previously led Amazon’s energy, water and sustainability teams.
Executives at Amazon, Nvidia and Anthropic would not commit to using coal, mostly dodging the question when asked during the panel at the Oklahoma City conference.
“It’s never a simple answer,” Amazon’s Miller said. “It is a combination of where’s the energy available, what are other alternatives.”
Nvidia is able to be agnostic about what type of power is used because of the position the chipmaker occupies on the AI value chain, said Josh Parker, the company’s senior director of corporate sustainability. “Thankfully, we leave most of those decisions up to our customers.”
Anthropic co-founder Jack Clark said there are a broader set of options available than just coal. “We would certainly consider it but I don’t know if I’d say it’s at the top of our list.”
Sahlstrom said Trump’s executive order seems like a “dog whistle” to coal mining constituents. There is a big difference between looking at existing infrastructure and “actually building new power plants that are cost competitive and are going to be existing 30 to 40 years from now,” the Tract executive said.
Coal is being displaced by renewables, natural gas and existing nuclear as coal plants face increasingly difficult economics, Sahlstrom said. “Coal has kind of found itself without a job,” he said.
“I do not see the hyperscale community going out and signing long term commitments for new coal plants,” the former Amazon executive said. (The tech companies ramping up AI are frequently referred to as “hyperscalers.”)
“I would be shocked if I saw something like that happen,” Sahlstrom said.
Coal retirements strain grid
But coal plant retirements are creating a real challenge for the grid as electricity demand is increasing due to data centers, re-industrialization and the broader electrification of the economy.
The largest grid in the nation, the PJM Interconnection, has forecast electricity demand could surge 40% by 2039. PJM warned in 2023 that 40 gigawatts of existing power generation, mostly coal, is at risk of retirement by 2030, which represents about 21% of PJM’s installed capacity.
Data centers will temporarily prolong coal demand as utilities scramble to maintain grid reliability, delaying their decarbonization goals, according to a Moody’s report from last October. Utilities have already postponed the retirement of coal plants totaling about 39 gigawatts of power, according to data from the National Mining Association.
“If we want to grow America’s electricity production meaningfully over the next five or ten years, we [have] got to stop closing coal plants,” Energy Secretary Chris Wright told CNBC’s “Money Movers” last month.
But natural gas and renewables are the future, Sahlstrom said. Some 60% of the power sector’s emissions reductions over the past 20 years are due to gas displacing coal, with the remainder coming from renewables, Sahlstrom said.
“That’s a pretty powerful combination, and it’s hard for me to see people going backwards by putting more coal into the mix, particularly if you’re a hyperscale customer who has net-zero carbon goals,” he said.
A federal court judge in Michigan has placed the once-promising electric truck brand Bollinger Motors’ assets into receivership following claims that the company’s owners still owe its founder, Robert Bollinger, more than $10 million.
Bollinger Motors first came to fame in the “draw a truck, get a billion dollars” stage of the EV revolution that saw Nikola rise to a higher market cap than Ford for a brief time. Robert Bollinger wasn’t able to capitalize quickly enough to get his trucks into production, though – and a late stage pivot to sell the brand to Mullen Automotive and launch a medium-duty commercial truck doesn’t appear to have been enough to save it.
Now, Automotive News is reporting on some of the more convoluted details of the Mullen purchase deal, with Robert (for ease of distinguishing the man from the brand) claiming that Mullen Automotive owes him more than $10 million for a loan he made to the company in 2024.
Just how Robert ended up giving Mullen Automotive $10 million to take his eponymous truck brand off his hands is probably one of those capitalistic mysteries that I’ll never understand, but Mullen’s response was perfectly clear: they didn’t even bother to show up to court.
Bollinger claims that at least two suppliers are also suing Mullen for unpaid debts. As such, the Honorable Terrence G. Berg has put the Bollinger brand into receivership, and its assets have been frozen in preparation for everything being liquidated. Worse, for Bollinger, the official court filings reveal a company that is really very much doing not awesome:
The testimony and evidence—which Defendant’s counsel conceded accurately reflected Defendant’s finances—showed that Defendant is in crisis. For months Defendant has owed more than twenty million dollars to suppliers, contractors, service providers, and owners of physical space. These debts are owed to parties who are critical for Defendant’s functioning. CEO Bryan Chambers testified that Defendant was locked out of its production facilities on May 5, 2025, and that the owner of the production facilities was seeking to permanently evict Defendant. The Court heard that Defendant had been prevented from accessing its critical manufacturing accounting system for a short time at the end of April 2025, before making a partial payment to restart services.
US DISTRICT COURT EASTERN DISTRICT OF MICHIGAN
I’m not sure if you caught all that, but Bollinger’s CEO has been locked out the company’s facilities and getting evicted, the company is more than $20 million in debt, and that debt is owed to people Bollinger absolutely needs in order to keep going.
You can read the full court decision, which I’ve embedded here, below. Once you’ve taken it all in, feel free to rush into the comments to say you told me so, since I really thought hoped the Bollinger B1 had a shot. Silly me.

BYD is about to launch an even smaller EV, but this one’s a little different. It’s BYD’s first kei car. You know, those tiny vehicles that dominate Japan’s city streets? BYD’s mini EV was just spotted out in public, giving us our first real look at the upcoming kei car.
BYD’s first mini EV was spotted in public
Last week, rumors surfaced that BYD was developing its first kei car, which would compete with top-selling models from Nissan, Honda, Mitsubishi, and other Japanese brands.
Kei cars, or “K-Car,” as they are sometimes called, are a class of ultra-compact vehicles that cannot be longer than 3.4 meters (134″). To put that into perspective, BYD’s smallest EV currently, the Seagull (called the Dolphin Mini overseas), is 3,780 mm (148.8″) long.
The mini vehicles are ideal in Japan because they are so small, making it easy to get around tight city streets. They are also more affordable and efficient than larger vehicles.
BYD’s mini EV was spotted for the first time during a road test this week by IT Home (via CarNewsChina), revealing a familiar look. It has that boxy, compact look of a typical kei car with sliding side doors.
According to reports, BYD is developing a new platform for the model. It will reportedly include a 20 kWh battery, good for 180 km (112 miles) WLTC range. By using its in-house Blade LFP batteries, BYD is expected to have a cost advantage.
BYD’s upcoming mini EV is expected to start at around 2.5 million yen, or about $18,000. That’s about the same as the Nissan Sakura (2.59 million yen), Japan’s best-selling EV last year.

Last year, around 1.55 million kei cars were sold in Japan, accounting for roughly 40% of new vehicle sales. Honda’s N-Box was the top-selling kei car (EV or gas) for the third straight year.
As Nikkei reported, some are already calling BYD’s electric kei car “a huge threat.” A Suzuki dealer said, “Young people do not have a negative view of BYD. It would be a huge threat if the company launches cheap models in Japan.”
BYD already sells several electric cars in Japan, including the Atto 3 SUV, Dolphin, and Seal. Last month, the company launched the new Sealion 7 midsize electric SUV, starting at 4.95 million yen ($34,500).
Although Japan isn’t really an EV hot spot, with sales falling 33% in 2024 to just under 60,000 units, BYD sees an opportunity.
By making virtually every car component in-house, including batteries, BYD can offer EVs at such low prices while still making a profit. BYD’s cheapest and best-selling electric car, the Seagull, starts at under $10,000 (69,800 yuan) in China.
With new smart driving and charging tech rolling out, BYD’s electric cars are getting smarter and even more efficient.
Can BYD’s mini EV compete with Japanese brands? At the right price, it may have a chance. Check back soon for more on the upcoming kei car. We’ll keep you up to date with the latest.
