technology has the potential to help mitigate global warming if widely deployed.
How it works
Hot rocks underground heat water to produce steam.
We drill holes down to the hot region, steam comes up, is purified and used to drive turbines, which
drive electric generators.
There may be natural "groundwater" in the hot rocks anyway, or we may need to drill more holes and
pump water down to them.
The first geothermal power station was built at Landrello, in Italy, and the second was at Wairekei in
New Zealand. Others are in Iceland, Japan, the Philippines and the United States.
In Iceland, geothermal heat is used to heat houses as well as for generating electricity.
If the rocks aren't hot enough to produce steam we can sometimes still use the energy - the Civic
Centre in Southampton, England, is partly heated this way as part of a district heating scheme with
thousands of customers..
