2. Whatisthis?
Geothermal energy is
literally heat from the
earth. It is produced by
the release of
radioactive elements in
the soil of the earth. In
some places, the heat is
concentrated close
enough to deep water
or surface water, and
there is enough of it to
warm it up.
3. GeothermalenergyinPoland
Poland has very good
geothermal conditions, as 80%
of the country's area is covered
by 3 geothermal provinces:
Central European, Pre-
Carpathian andCarpathian.The
water temperature for these
areas ranges from 30–130 ° C
(and locally even 200 ° C), and
the depth of occurrence in
sedimentary rocks ranges from 1
to 10 km. In this country, more
than 90% of the energy used for
heating comes from geothermal
energy
4. Use
Geothermal energy can be used by
individual households. Usually in
this context it is referred to the so-
called shallow geothermal energy,
which is based on the use of the
above-mentioned heat pumps.
Home geothermal heating works
with traditional installations such as
radiators or floor systems.This
method of heating is very efficient
and effective, and the underground
installation is characterized by low
operating costs. It should be noted,
however, that the initial expenses
are quite high - they start from tens
of thousands of zlotys
5. no emission of harmful substances to
the atmosphere and renewable. Its
generation does not adversely affect
the climate or the environment.
It is independent of weather
conditions and its power is evenly
distributed throughout the year. It is
easier to predict how much energy
will be obtained because there are no
additional factors determining its
efficiency.This is the advantage of
geothermal energy over renewable
energy sources such as the sun or
wind.
Low operating costs
Benefits
6. its use is not possible in every area.
Firstly, not everywhere are equally
effective sources (i.e. those with an
appropriate temperature). Secondly,
even if they are somewhere below the
surface, sometimes it is so deeply
embedded that it is not profitable to
mine it.
High cost
Hazardous gases and minerals may be
released during extraction
Technical problems in the maintenance
of equipment
Disadvantages
7. Currently, the largest
islandTenerife is already
generating about 42% of
its electricity from wind
power. Primary evidence
of the geothermal
potential which exists
comes from an
underground hydrothermal
system in the subsoil of
Tenerife with a
temperature of 275°C.
