Geothermal power plants turn
heat from under the Earth into
electricity. It’s a way of
making power with practically
no pollution. And, according
to a new report, there are more
companies investing in this kind
of energy. Mark Brush has more:

The report was put out by the Geothermal Energy Association. They found the number of geothermal power plant projects being developed jumped by 46% compared to 2008.

They say the jump was driven by federal stimulus money. And some state laws that mandate that utilities provide a certain percentage of renewable power.

Karl Gawell is with the Geothermal Energy Association. He says, right now, there are specific places where these power plants work best.

“Well, the best reservoirs right now tend to be in the western United States. And in areas where the heat of the Earth actually comes closer to the surface of the Earth. But, you know, the potential is nationwide.”

Gawell says we don’t have good technology to find new heat reserves under the Earth. And, until we invest in better exploration technology, we won’t know where to find these hot spots.

For The Environment Report, I’m Mark Brush.
