Geothermal EnergyPublished: 2015-11-19 | Original Article
In the decades ahead, geothermal energy is expected to boom as scientists find a commercially viable way to tap energy deep beneath the Earth's crust.
Overseas, researchers in Iceland have spent several years drilling straight into volcanoes to access very hot water and magma deposits, with an eye toward eventually developing these high-temperature resources into far more prolific geothermal power stations. The goal is to develop more advanced technologies that can be exported in the next decade.
If that research pays off, it could soon be possible to tap much hotter geothermal resources around the globe that can produce 10 times as much energy as today's geothermal facilities. It might even one day be feasible to drill geothermal wells offshore; researchers estimate that massive stores of heat energy are reachable just 1,000 meters below the seabed at the Juan de Fuca Ridge off the coast of Washington state.
