2.  At the moment, most of the world's energy comes from non-renewable
fossil energy resources, namely: oil 35%, coal 29%, gas 24%, nuclear 6% .
However, these energy resources are dicreasing day by day.
 New technologies are developed to build up energy which comes from
natural resources such as sunlight, wind, rain and geothermal heat
which are naturally replenished. In recent years, interest in these sources
has grown as environmental awareness grows in our society and as
governments and industry look for environmentally sound alternatives to
the use of fossil fuels.
 Podkarpackie province is the region where the sources of renewable
energy are particularly rich . The favourable climate conditions namely;
winds and good insolation are used to generate electricity. A lot of our
province ’s renewable energy supply comes from biomass, which is
produced by burning wood, wood wastes or plant materials.

4.  Water energy (water power engineering) deals with gaining energy from
the gravitational force of falling or flowing water. It is converted into
mechanical and electrical powers through the use of water turbines
and generators in hydroelectric power plants.

7.  Advantages:
 1. Hydropower has a moderate to high amount of useful energy and
fairly low operating and maintenance costs.
 2. Hydroelectric power plants emit very little heat-trapping carbon
dioxide and other air pollutants during operation.
 3. The dams that are used in the power plants help prevent flooding
and supply a regulated flow of irrigation water to the areas below
the dam
 Disadvantages:
 1. A hydroelectric power plant takes up a lot of space and this may
cause animal habitats to go lost.
 2. Hydro power dams can damage the surrounding environment
and alter the quality of the water by creating low dissolved oxygen
levels, which impacts fish and the surrounding ecosystems.
 3. Dams stop migration of aquatic species like salmon to the ocean.
 4. Large-scale projects can threaten recreational activities and
disrupt the flows of rivers

8. Wind power is one
of the oldest
rewnewable
sources of energy
used by the
human being.
Nowadays, wind
turbines convert
kinetic energy from
the wind into
mechanical
energy to produce
electricity by
means of windmills
with three blades.

10. Advantages:
1. The wind power consumes no fuel, and emits no air pollution, unlike
fossil fuel power sources
2. The vegetation clearing and ground disturbance required for wind
farms is minimal compared with coal mines and coal-fired power
stations, If wind farms are decommissioned, the landscape can be
returned to its previous condition.
3. Wind farms are symbols of energy independence and local prosperity,
some of them have become tourist attractions,
4. An average turbine provides 63-78 times more energy than used to
construct, operate and eventually dismantle the turbine.
Disadvantages:
1. Migrating birds or bats may be injured or killed by direct impact with
turbine blades, towers, or transmission lines.
2. Rotating turbine blades produce noise and "shadow flicker" when the
sun passes behind the turbine.

11. Geothermal energy is defined as heat from the Earth. It is a clean,
renewable energy resource because the heat emanating from the Earth's
core where the temperature can reach more than 6,000 degrees Celsius is
essentially limitless. Geothermal power plants capture this heat and convert
it to energy in the form of electricity.

15. Advantages:
1. Significant Cost Saving : Geothermal energy generally involves low running
costs since it saves 80% costs over fossil fuels and no fuel is used to generate
the power.
2. Reduce Reliance on Fossil Fuels : Dependence on fossil fuels decreases with
the increase in the use of geothermal energy. With rising prices of oil, many
countries are pushing companies to adopt these clean sources of energy.
3. Environmental Benefits : Being the renewable source of energy, geothermal
energy has helped in reducing global warming and pollution.
4. Direct Use : Since ancient times, people having been using this source of
energy for taking bath, heating homes, preparing food and today this is also
used for direct heating of homes and offices.
5. Job Creation and Economic Benefits : Geothermal energy on the other hand
has created many jobs for the local people.

16. 1. High Installation Costs : To get geothermal energy, requires
installation of power plants, to get steam from deep within
the earth and this require huge one time investment and
require to hire a certified installer and skilled staff needs to be
recruited and relocated to plant location.
2. Can Run Out Of Steam : Geothermal sites can run out of steam
over a period of time due to drop in temperature or if too
much water is injected to cool the rocks and this may result
huge loss for the companies which have invested heavily in
these plants.
3. Suited To Particular Region : It is only suitable for regions where
temperature below the earth are quite low and can produce
steam over a long period of time.
4. May Release Harmful Gases : Geothermal sites may contain
some poisonous gases like carbon dioxide and methane,
they can escape deep within the earth, through the holes
drilled by the constructors.
