A Geothermal Project Could Provide Unlimited Electricity From Underground Heat

It's a "game-changer."

In Alberta, Canada, a project is underway to harness geothermal energy and turn it into electricity.

The $10 million project, called the Eavor-Loop, is being run by Eavor Technologies. It's been called a "game-changer" because it's something that could be built underground in someone's backyard. Like solar panels or windmills, geothermal energy is sustainable, creates no greenhouse gas emissions and uses naturally occurring resources to create energy.


"It's using a lot of traditional building blocks but rearranging them in unusual fashion," John Redfern, president and CEO of Calgary-based Eavor Technologies, told CBC.

The Eavor-Loop works by harnessing the natural heat produced beneath the Earth's surface. Two wells are drilled underground and then connected to each other. The Eavor-Loop team uses a fluid that travels through the loop and collects heat from the surface, then brings it above ground so it can be converted into electricity. 

"It's just a much more benign system and it's something that you can implement across 80 percent of the world instead of five percent of the world like traditional geothermal," Redfern told CBC. "You can put it almost anywhere. It's not like a windmill or solar panel … almost everything's underground so you can literally put it in someone's backyard."
