The Biden Administration recently announced nearly half a billion dollars from both the Inflation Reduction and Infrastructure laws would go toward clean energy projects at former coal mines. Some will be solar farms at the sites, but there is a lesser known opportunity inside the mines: Geothermal energy.
Abandoned coal mines generally fill with water when the mining has ceased. That water contains heat from far below the earth’s surface. People can drill bore holes to bring that heat to the surface, then pass it through heat exchanges and heat pumps in buildings and in homes.
The first neighborhood mine-water heating scheme in Great Britain just went into full operation at the end of March and will eventually serve over 1,200 homes.
“Each minable scheme poses its different challenges, and there will be expenses involved with drilling bore holes or laying district heat network pipes in the ground,” explained Gareth Farr, head of heat and by-product innovation at the Coal Authority in Mansfield, England. “But hopefully most of these schemes, if not all of them, will be able to operate at a similar or better cost to the traditional fossil-fuel heating schemes we have at the moment.”
Geothermal energy is not new, but taking it from abandoned coal mines is not yet common, especially in the United States.
Professor and director of the Environmental Studies Program at Ohio University, Natalie Kruse-Daniels, and her students are studying abandoned mines in Appalachian Ohio to see which ones are close enough to towns to be used for home heating.
“It’s this untapped energy source that could reduce bills, that could make energy more efficient, that could reduce some reliance on fossil fuels,” said Daniels, who has been fascinated with coal mines since childhood.
Geothermal energy from coal mines can be used not only to heat homes and buildings, but also to cool them. That opens up many more opportunities, especially for data centers. They are some of the worst carbon offenders, using vast amounts of energy and requiring thousands of gallons of water to cool themselves. Now, researchers in Scotland are studying how hot air from data centers can be pumped into coal mines and then recovered from the water to heat other buildings.
“We can store heat in mines, and we do hope that actually this could become part of vital heat storage. Storage is key, of course, for a lot of renewable energies,” explained Farr.
Coal fields run under at least 20 states in the U.S.
In Ohio there are more than 4,000 abandoned mines, a wealth of opportunity for geothermal energy. In 2007, the U.S. Department of Energy reported that the amount of water currently being discharged from underground coal mines in just the Pittsburgh coal seam could potentially be used to heat and cool roughly 20,000 homes.
So why isn’t it happening? Kruse-Daniels said that while it is a relatively inexpensive form of clean energy, the location and legacy may be liabilities.
“I think some of it’s out of sight, out of mind, right? When we look at investment in new technology and investment in clean energy in Appalachia, it’s limited,” said Kruse-Daniels.
Coal is controversial, so investors don’t target the coal regions, which, she says, is a mistake.
“In a less predictable climate and in a warmer world, this opens up an opportunity for turning this legacy, this liability, into a resource,” she added.

The third of a quintet of West Virginia solar farms just came online, and while that’s a renewable milestone, there’s a disappointing hitch.
3 out of 5 West Virginia solar farms are online
FirstEnergy subsidiaries Mon Power and Potomac Edison have launched a 5.75 megawatt (MW), 17,000-panel solar farm at Marlowe in Berkeley County. The new solar farm sits on about 36 acres of land along I-81 and the Potomac River – land that used to store ash from the retired R. Paul Smith Power Station.
In 2022, FirstEnergy wrapped up a major cleanup effort, pulling more than 3 million tons of ash from the site to be reused in cement manufacturing. With the landfill officially closed, the company cleared the way to turn the former waste site into a clean energy generator as part of its solar program. Fifty-four local union workers constructed the solar farm, which features US-made solar panels, a racking system, and electrical equipment.
It’s the third of Mon Power and Potomac Edison’s five solar farms that will generate up to 50 MW of clean energy combined. The companies completed their first solar farm at Fort Martin Power Station (18.9 MW) in early 2024, and their Rivesville solar site (5.5 MW) came online last fall. In total, the companies now have 30 MW of solar capacity.

Electrek’s Take
Combined, the five projects will create more than 87,000 Solar Renewable Energy Credits (SRECs) available for purchase by customers for 4 cents per kilowatt hour in addition to normal rates. Aside from the essential benefit of cutting carbon emissions, there isn’t anything else in it for customers, apart from spending, on average, an extra $40 or so a month out of the goodness of your heart to go solar. Heck, you don’t even get a T-shirt.
Mon Power and Potomac Edison – why are customers being charged MORE to buy into solar in West Virginia? That’s a stick, not a carrot. (And WV? Coal’s not coming back. It doesn’t matter what Trump says.)
But solar growth anywhere is something to be cheerful about, and solar energy in coal-state West Virginia is progressing. According to the Solar Energy Industries Association, as of Q4 2024, 205 MW of solar is installed in West Virginia. So, it’s no surprise that it’s at the bottom – it’s ranked 49th in the US for the amount of solar installed. However, it’s projected to reach 40th place over the next five years with 1,064 MW, so at least it’s expected to improve.

Is the Kia EV4 GT the affordable electric sports car we’ve been waiting for? Kia’s first global electric sedan is about to get a sporty upgrade. After the EV4 GT was spotted in public, we’re finally getting a glimpse of the interior.
Kia EV4 GT spotted, revealing first look at the interior
The EV4 arrives as one of the most highly anticipated electric cars of 2025. After opening orders in Korea earlier this year, Kia will launch it in Europe later this year and the US in 2026.
Kia’s electric sedan starts at just 41.92 million won, or around $30,000 in Korea. Although prices for Europe and North America have yet to be revealed, the entry-level EV is expected to start at around $35,000 to $40,000.
Despite its typical four-door design, Kia labels it as an “entirely new type of EV sedan” with a wide stance and fastback silhouette.

Kia will launch the EV4 in the US next year, featuring a built-in NACS port to access Tesla Superchargers and an EPA-estimated driving range of up to 330 miles. Prices will be revealed closer to launch, but the EV4 is expected to start at around $35,000 to $40,000. The GT variant could cost upwards of $50,000 to $55,000, with the 2025 Kia EV6 GT starting at $63,800.
The Tesla Model 3 Performance starts at $54,990 in the US with 298 miles range and a 0 to 60 mph time in 2.9 seconds.
Will the Kia EV4 GT match it? Let us know your thoughts in the comments.

Trump’s tariffs are about to drive up the cost of clean energy projects in the US, and energy storage is set to take the biggest hit, according to new analysis from Wood Mackenzie.
In its latest report, “All aboard the tariff coaster: implications for the US power industry,” Wood Mackenzie lays out what the power sector could be in for as new tariffs raise costs across the board. The biggest tariff hit will be on utility-scale energy storage, where US projects still overwhelmingly rely on imported battery cells from China.
“In a business with 5-to-10-year planning cycles, not knowing what a project will cost next year or the year after is disruptive and causes massive uncertainty,” said Chris Seiple, vice chairman of power and renewables at Wood Mackenzie. “We will definitely see impacts on power sector capital projects. The severity depends on what scenarios play out.”
The firm modeled two scenarios: one where tariffs settle at an effective rate of 10% by 2026, and a more extreme “trade war” scenario where that rate climbs to 30% and stays there through 2030. Either way, energy storage takes a big hit.

Wood Mackenzie estimates energy storage project costs could rise from 12% to over 50%, depending on the scenario. That’s because, in 2024, nearly all utility-scale battery cells used in the US came from China. And the domestic supply is nowhere near ready to take over.
“While US battery cell manufacturing capacity is expanding, it is not expanding at a pace nearly fast enough to meet even a small fraction of battery projects in the US,” Seiple said. “In 2025, we estimate there is sufficient domestic manufacturing capacity to only meet about 6% of demand, and by 2030, domestic manufacturing could potentially meet 40% of demand.”
The solar sector is getting a rough deal, too. With existing tariffs and tough interconnection rules already making solar builds more expensive in the US, new tariffs would pile on. Wood Mackenzie says utility-scale solar could end up 54% more expensive than in Europe, and a staggering 85% pricier than new solar plants in China.
“An increase in tariff levels will only worsen this premium US energy consumers need to pay to access renewable energy,” Seiple said.
Wood Mac’s bottom line: Current trade policies are making clean energy more expensive to build in the US than almost anywhere else, and the industry will have to brace for more uncertainty and higher costs ahead.
