WHAT IS IT?
Geothermal power is power that is taken from the earth to
Geothermal power has been used since Roman times when it
was used to heat the flooring of Roman villas and to heat
Nowadays geothermal power is known as a renewable energy
because it is limitless since it heat generated by the earth
HOW DOES IT WORK?
Geothermal power works by channelling the heat, that is
emitted by the earths molten core, and making it heat water
so that it becomes steam so that it can turn a turbine that is
connected to a generator; which will make electricity from
the spinning of the turbine.
Possibly, a pipeline that can channel some of the geothermal
heat will be directed towards homes and buildings so as to
WHERE IS IT USED?
Geothermal power is used, mostly, where there is current
tectonic activity because, in theses areas, there is a more
heat being generated.
Examples of places where this type of power is used are;
· Iceland; in Iceland there is a high concentration of volcanoes
and the heat generated by the lava from these volcanoes is
used to make energy as well as heat houses and even
NESJAVELLIR GEOTHERMAL PLANT
Nasjavellir geothermal plant is located in Iceland and is the
second largest plant in the country. It produces
approximately 120MW of electrical energy, and produces
around 1'800 litres of hot water per second, servicing the hot
water needs of the Greater Reykjavík Area.…read more
There are several advantages of geothermal energy which are;
· Theoretically an inexhaustible energy source (it will never
· There is no pollution (it produces no green house gases)
· It is an excellent supplement for other renewable sources (it
can be used when wind power decreases)
· It does not require any structures such as solar panels or
wind-turbines to collect energy (it can be used directly to
heat or produce electricity)
· It is very cheap…read more
