Geothermal Energy

Here’s a good video on geothermal energy that explains the science in a way everyone can understand.

Not surprisingly, it suggests there’s more promise here than there actually is, since most of the planet’s land mass is completely unsuitable for this technology. I had to laugh when the guy said, “In places that meet all these criteria, geothermal energy could grow by as much as 28% over the next four years. That’s 6.4% per year, which is essentially what General Motors pays its bondholders.
