Energy for Life, Highest Good Economics

Geothermal Energy a ‘Red Hot Renewable’ expanding globally

I believe that geothermal energy in one of the problem solving technologies that has the potential and promise to transform our socio energy future for the long term.   Earths hot core will not be cooling for many many years and investing in geothermal electrical production is the right thing to do for those living today and for future generations.   Enjoy this really encouraging article by Casey Danson………..

The advancement could be especially valuable in Iceland, a country that has capitalized on its unique geology to derive a quarter of its electricity production and around 90 percent of household heating from geothermal energy.

And it’s just the latest innovation in a series of geothermal energy breakthroughs dating back a century to the first geothermal power generation in Italy in 1906. As these advancements continue, geothermal energy is clearly becoming a major renewable energy source waiting to be tapped — one that’s literally sitting beneath our feet.

“The worldwide market is moving towards double-digit growth,” said Karl Gawell, executive director of the Geothermal Energy Association (GEA) during the organization’s recent International Geothermal Showcase in Washington, DC. “There’s lots of exciting things going on. Several years ago there were projects in 24 countries, this year almost 700 projects are under development in 76 countries across the globe.”

When it isn’t drawing on magma-heated steam, geothermal energy is generated by water heated in underground geothermal reservoirs to create steam and turn an electricity-generating turbine. The hotter the ground, the hotter the resource and the more energy can be generated. Iceland lies on two major fault lines and is one of the most tectonically active places on Earth, making it an obvious geothermal hot spot. The aim of many of the recent technological advances is to generate geothermal power economically from lower subterranean heat levels found around the planet.
