Geothermal Power
There are two basic types of geothermal power. The one most often thought of is the type
used in places like Iceland,
California and New Zealand. This uses naturally occurring hot water and
steam in volcanic areas. One disadvantage of this system in certain areas is that it will destroy natural features including geysers. The geysers in Yellowstone hare protected by law. However there are many areas where this does not hapopen.
This system is
used very effectively in limited areas, but cannot be used in Australia which has no suitable
volcanic areas.
The other type involves using hot rocks which are
dry. Then you can pump cool water down a
deep bore and bring it up from another bore hot.
