Not yet exploited: I'm a big fan of deep bore geothermal energy using a closed loop. Here's an example from a company trying to make it work. Idk if they can actually do it but it can def be done by a large enough entity. https://www.youtube.com/watch?v=PtQmGPmyLA0 https://www.youtube.com/watch?v=PtQmGPmyLA0 Build some pipes in the ground. Pump an anti-freeze like fluid into the ground so it heats up. Bring it up on the other side and the heat from the fluid heats some steel pipes submerged in water so the water turns to steam. Steam turns turbine and electricity is generated. You can either send it straight to market or you could store it via batteries, flywheels, compressed air, your choice. Lots of areas where energy could be lost but the earth is hot so it's not like we're depleting a resource
