In an energy-efficient future, homes may be heated and cooled by pumping from giant pools of water stored underground. A study published this month in Applied Energy looks at how underground aquifers could help significantly reduce reliance on fossil fuels and help store energy produced by renewables.This Summer’s Hottest UmbrellaThe research deals with a technology known as aquifer thermal energy storage, or ATES. Water is a great way to store thermal energy, and the Earth is an efficientinsulator. ATES is simply the…

As we head into a world of electric cars, charging is the biggest concern for many first-time buyers. It makes sense. While the hype for electric cars themselves is arguably justified, the biggest drawback is the fact that you have to charge them, and right now, that can be a bit of a hassle. That’s not only because of the fact that you have to wait to charge — but also because of the fact that there are different types of electric car chargers, and you may not be able to charge an electric car with all of those…

A year ago, I bought a new Jeep Wrangler. A plug-in hybrid model! And I wasn’t shy about my reasoning for buying the PHEV version of the Wrangler: I chose this powertrain over the gas-only versions purely because it qualified for the federal government’s $7,500 EV tax credit. Turns out, that was a pretty big motivator for a lot of Americans. The Jeep Wrangler 4xe was the best-selling plug-in hybrid (PHEV) in the U.S. in 2022, beating out a wide range of more affordable and practical cars. The 4xe accounted for nearly…

Electric cars have come a long way over the past few years.

Aluminum foil, trays,…
