About

Deep beneath the Earth sits 50,000 times more energy than all the world's fossil fuel reserves, but accessing it requires using the same controversial technology that oil companies spent trillions to develop: fracking. Cindy Taff left Shell to prove that drilling for geothermal heat instead of hydrocarbons can deliver what solar, wind and fossil fuels can't — clean, renewable power at all times, regardless of weather. Could this be the breakthrough that finally solves our energy challenges?
