1,500 new Colorado homes will come with geothermal heat pumps
Over the next two years, homebuilder Lennar is outfitting more than 1,500 new Colorado homes with Dandelion Energy’s geothermal systems in one of the largest residential geothermal rollouts in the US.
The big draw for homeowners is lower energy bills and cleaner heating and cooling. Dandelion claims Lennar homeowners with geothermal systems will collectively save around $30 million over the next 20 years compared to using air-source heat pumps. Geothermal heat pumps don’t need outdoor AC units or conventional heating systems, either.
Geothermal systems use the sustained temperature of the ground to heat or cool a home. A ground loop system absorbs heat energy (BTUs) from the earth so that it can be transferred to a heat pump and efficiently converted into warmth for a home. Dandelion says its ground loop systems are built to last for over 50 years and should require no maintenance.
Dandelion’s geothermal system uses a vertical ground closed-loop system that is installed using well-boring equipment and trenched back into the house to connect to a heat pump. The pipes circulate a mixture of water and propylene glycol, a food-grade antifreeze, that absorbs the ground’s temperature. A ground source heat pump circulates the liquid through the ground loops and it exchanges its heat energy in the heat pump with liquid refrigerant. The refrigerant is converted to vapor, compressed to increase its temperature, then passed through a heat exchanger to transfer heat to the air, which is circulated through a home’s HVAC ductwork.
Daniel Yates, Dandelion Energy’s CEO, called the partnership with Lennar a “new benchmark for affordable, energy-efficient, and high-quality home heating and cooling.” By streamlining its installation process, Dandelion is making geothermal systems simpler and cheaper for homebuilders and homeowners to adopt.
This collaboration is happening at a time when Colorado is pushing hard to meet its clean energy targets. Governor Jared Polis is excited about the move, calling it a win for Coloradans’ wallets, air quality, and the state’s leadership on geothermal energy. Will Toor, executive director of the Colorado Energy Office, said that “ensuring affordable access to geothermal heating and cooling is essential to achieve net-zero emissions by 2050, and we’re excited to be part of such a huge effort to bring this technology to so many new Colorado homes.”
And it’s not just about cutting emissions – geothermal heat pumps help reduce peak electric demand. Analysis from the Department of Energy found that widespread adoption of these systems could save the US from needing 24,500 miles of new transmission lines. That’s like crossing the continental US eight times.
Colorado is making this transition a lot more attractive through state tax credits and Xcel Energy’s rebate programs. These incentives slash upfront costs for builders like Lennar, making geothermal installations more financially viable. The utility’s Clean Heat Plan and electrification strategy are working to keep energy bills low while meeting climate goals.

Tesla has officially launched a new version of the Cybertruck RWD for $70,000 in the US and Mexico.
It’s more expensive than previously announced and loses a ton of features, but it has more range.
Earlier today, we reported on Tesla unveiling in the Middle East a new ‘Cybertruck Long Range’.
The automaker confirmed that it had a single rear-wheel-drive (RWD) motor, but unlike the previously announced Cybertruck RWD, Tesla said it had 350 rather than 250 miles of range.
This would point to having the same battery pack as the Dual Motor and Cyberbeast currently available.
At the time, it wasn’t clear if Tesla was launching this specific version for the Middle East or if it was the new Cybertruck RWD to replace the previously announced $62,000 version.
Now, Tesla has opened orders in the online configurator for the US and Mexico of the new Cybertruck Long Range RWD:
It starts at $70,000 before incentive – $9,000 more than the previously announced Cybertruck, but it has 100 more miles on a single charge at 350 miles.
It’s also $10,000 less expensive than the Cybertruck Dual Motor.
You not only lose a motor, but you also lose the powered tonneau. You can buy a “soft tonneau” for $750 and it increases the range to 362 miles:
The new cheaper version also loses the adaptive suspension, the lightbar at the back, the rear screen, and even the bed outlets, according to Tesla’s website.
Tesla says that deliveries are going to start in June.
Electrek’s Take
I might be wrong, but I would assume that the previously announced $61,000 Cybertruck is not going to happen. The Cybertruck is likely proving to be too low-volume to warrant producing different sizes of battery packs.
However, this version might be just to make the $80,000 Cybertruck look better.
It’s not to lose the AWD, the tonneau, the adaptive suspension, and even the bed outlets for $10,000.
These are all pretty essential features of the Cybertruck. I don’t think this version will sell much at $70,000. Maybe they get a few sales of people trying to take advantage of the $7,500 tax credit.

![This electric excavator has battery swap tech that lets it recharge in minutes [update]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/04/electric-excavator.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
The electric construction equipment experts at XCMG just released a new, 25 ton electric crawler excavator ahead of bauma 2025 – and they have their eye on the global urban construction, mine operations, and logistical material handling markets.
UPDATE: telematics announcement.
Powered by a high-capacity 400 kWh lithium iron phosphate battery capable of delivering up to 8 hours of continuous operation, the XE215EV electric excavator promises uninterrupted operation at a lower cost of ownership and with even less downtime than its diesel counterparts.
XCMG is delivering on part of that reduced downtime promise with the lower maintenance and easier repair needs of electric equipment, and delivering on the rest of it with lickety-quick DC fast charging that can recharge the machine’s massive battery in 1.5-2 hours … but that’s not the slick bit. The XCMG XE125EV can be powered up without leaving the job site thanks to its BYD battery swap technology.
We first covered XCMG and its battery swap technology back in January, and covered similar battery-swap tech being developed by MOOG Construction offshoot ZQUIP, as well – but while XCMG’s battery tech has been in production for several years, it’s still not widely known about in the West (even within the industry).
XCMG showed off its latest electric equipment at the December 2024 bauma China, including an updated version of its of its 85-ton autonomous electric mining truck that features a fully cab-less design – meaning there isn’t even a place for an operator to sit, let alone operate. And that’s too bad, because what operator wouldn’t want to experience an electric truck putting down 1070 hp more than 16,000 lb-ft of torque!?
Easy in, easy out
The best part? All of the company’s heavy equipment assets – from excavators to terminal tractors to dump trucks and wheel loaders – all use the same 400 kWh BYD battery packs, Milwaukee tool style. That means an equipment fleet can utilize x number of vehicles with a fraction of the total battery capacity and material needs of other asset brands. That’s not just a smart use of limited materials, it’s a smarter use of energy.
You can check out all the XE215EV’s specs at this tear sheet, and get an in-person look at the Chinese company’s latest electric excavator this week in Munich, Germany.
Telematics announcement at bauma
Earlier today, XCMG launched its next-generation Xrea Global Telematics Platform, integrating IoT, big data, cloud computing, and AI to enable what it’s caling, “seamless cross-border fleet management.”
The new telematics platform supports a dozen languages via PC and mobile interfaces, and offers real-time diagnostics, predictive maintenance, and data-driven optimization of both the vehicle and the vehicle’s batteries, empowering equipment managers and fleet operators to track fleets across town, or across time zones.
“XCMG remains committed to advancing engineering technology to empower a sustainable future. Our mission is to deliver efficient, intelligent, and eco-friendly lifecycle solutions for global clients,” said Mr. Yang Dongsheng, Chairman of XCMG Group and XCMG Machinery. “Today, 19% of our product portfolio comprises green innovations under our ‘Green Mountain’ new energy line, with full electrification across all series underway.”
