99% of the Earth's mass is hotter than 1000ºC (1832ºF). Australia has
the hottest non-volcanic rocks on Earth. 1 cubic kilometer of them
holds the equivalent energy of 40 million barrels of oil. Exploration
of this potentially unlimited clean energy has left the drawing board
and gone into the field.
Interesting stuff. How it works and details:

(at the lower half of this item). Ironically, this clean energy sits
just beneath dirty hydrocarbons. And not only is it clean but,
thankfully, quite invisible too - compared to wind turbines.
