Geothermal power, where energy is generated by drawing heat from the fluid found beneath the Earth's surface, is quickly becoming an appealing option. A new mapping tool from the U.S. Department of Energy shows the country's vast geothermal heat potential.
Can enormous heat deep in the earth be harnessed to provide energy for us on the surface? A promising report from a geothermal borehole project that accidentally struck magma – the same fiery, molten rock that spews from volcanoes – suggests it could.
Introducing ICCP-1, the world's first magma-enhanced geothermal system. Located in Iceland, it's an important proof-of-concept that could lead to a revolution in the energy efficiency of high-temperature geothermal areas across the globe.
John Denver proclaimed it "almost heaven", but a group of geoscientists are implying it's a little more like the opposite. Most of the rest of the world doesn't think of West Virginia as a hot spot, but it is.
