My New Interest In Geo-thermal Heating And Cooling

It looks like
geo-thermal heating and cooling is finally starting to show some progress here in the U.S. Iceland gets most of their energy from geothermal, of course. But it turns out that the U.S. has excellent geothermal resources as well, that we ought to be putting to better use.
I’ve been reading up on geothermal companies all over the web. I think the technology has great promise here, and it’s starting to take off in recent years.
I’m strongly considering installing a geothermal heating and cooling system in my home, as well as buying shares in geothermal companies.
Let me know what you think about all this.
