Clean energy is buried at the bottom of abandoned oil wells

"In case you missed it, our planet is in trouble. The UN climate report from early April makes clear we’re on a path that will careen past the climate goals set in the Paris Agreement, and we need to cut carbon emissions — fast. But while solar and wind power are important (they are, after all, key parts of the Biden administration’s climate plan) they’re the kind of thing we’ve seen plenty of before, which means they’ll only get us so far. What we need, the UN report says, is new solutions. Which is why a pilot program recently detailed by the US Department of Energy (DOE) is particularly intriguing. If it works, it could help solve multiple problems at once, using an often-overlooked solution: geothermal energy.

Geothermal energy works on a simple premise: The Earth’s core is hot, and by drilling even just a few miles underground, we can tap into that practically unlimited heat source to generate energy for our homes and businesses without creating nearly as many of the greenhouse gas emissions that come from burning fossil fuels. However, drilling doesn’t come cheap — it accounts for half the cost of most geothermal energy projects — and requires specialized labor to map the subsurface, drill into the ground, and install the infrastructure needed to bring energy to the surface."...
