2. What is the solar energy???
Solar energy is the energy that is released inside the
core of the Sun during fusion processes. This energy
is delivered to us by the sun-ray.

3. This is a
photovoltaic
panel too.

4. The Wind power
Wind power is the conversion of wind energy into
useful form. 1-3% of the energy of the Sun turns into
wind power on Erth. This is 50-100 times more than
the energy that is produced by photosynthesis of the
flora of Erth.

5. Wind turbines and wind farms
in Hungary
In order to a wind turbine to work efficiently the
annual average wind speed must be above 4-5
m/s. Good sites for wind plants are seashores.

6. As you are getting more
and more away from the
coast the wind loses its
power because of the
skin friction. So
Hungary is a calm place.
The six most important wind
power plants in Hungary
are: Inota Kulcs and four at
Mosonmagyaróvár.

7. What does Geothermal mean?
„Geothermal” comes from Greek words: „geo” means
earth and „therme” means heat. So the word
„geothermal” means erth-heat.

9. What is biomass and biomass
energy
Biomass is biological organic material.
Bimoass for energy is often used to mean plant based
material that can be used as fuel or for industrial
production.

10. Methods of using biomass
Directly
Indirectly

11. Hydroelectric power plant
An establishment that transforms the energy of
rivers, seas, watercourses into electricity.

12. What is the turbine?
A turbine is a rotary engine that transforms kinetic
energy from a fluid flow into mechanical energy by
rotors.
