This week's energy topic is geothermal and this one's not making the news as much... yet. But keep an eye on it, folks. Over at NexGen, I start with the basics:

Since I'm a closet classicist, let's start by breaking down geothermal from the Greek, Gus Portokalos style:

Okay. Geothermal comes from the Greek word geo, meaning earth, and therme, meaning heat. So, what do you energize your house with? You see: Heat from the earth. Geothermal. There you go!

So the source of geothermal energy is heat below the Earth's surface. Steam and hot water generated there provide electricity and heat buildings. And since rain replenishes the water involved and heat is continuously produced...it's completely renewable! Direct use has no negative impact on our environment and geothermal plants gives off low emissions. Not bad, eh?
