Geothermal Power
Part I: Creation of Geothermal
Scientists believe geothermal power
was created by matter exploding and
releasing new energy. This energy fuels the sun and makes heat
energy that is found in the earth. The water from the ocean interacts
with the earth's mantle. The mantel is a crust over the earth. When it
interacts with this crust it makes geothermal power possible. The
mantle traps the heat and warms the water. There are three different
reservoirs of geothermal power. They are dry steam, wet steam, and hot
water reservoirs.
Part II: Benefits and Drawbacks
There are some benefits and drawbacks to geothermal
power. Using
geothermal power production sites does not decrease the water supply in
the surrounding ecosystems. Geothermal power is also a non-polluting
source of energy. Geothermal power does have some consequences. Making
a geothermal site disturbs some surrounding ecosystems. Roads must be
built around geothermal sites which are too fragile for humans. There
are
about twenty countries that have geothermal power sites. "The United
States produces about forty-five percent of all geothermal power in
the world." Some scientists believe that number will increase.
