Eco Friendly Actions Alternative Energy Sources Compositions alternative energy sources ebook | Page 17

In my opinion we need to motivate people to start using alternative energy sources if we
want to live in the brighter future without any oil leaks into the ocean or contaminated
forests. Yes, maybe it‘s expensive to buy and install, but there‘s nothing more important
than our „mother“ Earth.

Geothermal energy
Geothermal energy is part of the renewable energy class (green) and represents the heat coming
from within the Earth (through rocks and underground fluids); Is obtained by capturing hot
water and steam from areas with volcanic and tectonic activity or underground heat. It can be
used for heating (dwelling, water), but also for producing electric current. It is a non-polluting
energy, and p eople have used hot springs for thousands of years for various purposes - for
bathing, as a source of cooking water, then in spa resorts and ultimately to produce energy from
them. Now, with geothermal energy, homes are heated, plants grow in greenhouses, crops dry,
water is heated in fish farms, industrial processes (such as pasteurization of milk) are being
carried out. The best example of looking at the benefits of geothermal energy is Iceland, where
hot water is extracted from various depths - from 500 meters deep, 150 ° C water, and from
1,000
meters
deep, 300 °
water . "Iceland
began
exploiting
decades ago,
70 years ago.
They realized
that, rather than
having toxic
ash from the
thermal power
plants, they'd
better use the
hot
water
beneath them.
Now, 80% of
their energy is
from
geothermal
resources and
12%
from
other renewable
resources.
Almost
all
homes in the
state
capital,
Reykjavik, are
heated
by
thermal water,
there is also domestic hot water, electricity is also obtained from geothermal resources by using
heat and steam "
Romania's geothermal potential has been revealed by experimental drilling and exploitation
over the past 25 years; Is not specific to the West, but there are such resources in other regions
of the country. The success rate of geothermal wells dug between 1995 and 2000 at depths of
1,500-3,000 meters was 86% (in fact, only two probes were unproductive). The geothermal
energy currently produced in Romania is used for heating homes, agriculture (in greenhouses),
industrial processes and, to a lesser extent, for various other purposes.
