Geothermal energy may sound tempting, but care is needed as South Korea found out.
By David Wojick, Ph.D. ~
There is a revolution coming in geothermal energy. How big it will be and how fast it can grow remains to be seen, but the revolutionary technology is here now.
We already know about the new technology by name — fracking. But that is fracking for oil and gas, the energy revolution we are already living on, that the greens hate. The geothermal revolution is fracking for heat.
Here is the technical bit. The Earth’s crust we live on is just a thin film wrapped around an 8,000 mile diameter molten ball. In some places under the deep ocean this crust is estimated to be just 3 miles or so thick. It is somewhat thicker under the continents but the point remains; it gets hot fast as you drill down into the crust. That heat is geothermal energy.
We have used geothermal energy to make…
