2. INDEX
Energy definition
● Types of energy
● Energy sources
● Renewable energy
● Non renewable energy
● Types energy of power
station:Hidra, solar, nucl., term,
eólic

3. Energy definition
● Definition: Energy is the capacity of a
physical system to perform work.

4. Types of energy
● Mechanical energy
● Electrical
● Electromagnetic energy
● Sound energy
● Chemical energy
● Nuclear energy
● Thermal or calorific energy

5. Mechanical energy
● Kinetic energy
● Potential energy

6. Kinetic energy
● Energy that objects have
when they're in motion

7. ● Energy that objects have when they're
moved from their stable position of
equilibrium
Potential
energy

8. ● Energy associated with an electrical current
Electrical energy

9. Electromagnetic energy
● Transported by
electromagnetic
waves, such as
radio, television
or X-ray waves

10. Sound energy
● Associated with the sound waves that are
transmitted through vibrations.

11. Chemical energy
● Stored in substances – it can be released or
absorbed during chemical processes

12. Nuclear energy
● Contained the nuclei of atoms

13. Thermal or calorific energy
● Comes from the vibration of particles in matter

14. ● Renewable energy
● Non-renewable energy
Energy

15. Renewable energy sources
● Hydraulic energy
● Solar energy
● Wind energy
● Marine energy
● Geothermal energy
● Biomass

16. Hydraulic energy
● Hydraulic energy is what is produced by the
water wich stored in reservoirs and lakes at
high altitude.

17. Solar energy
● Solar energy, radiant light and heat from the
sun.

18. Wind energy
Wind energy is the energy from wind, that is,
the kinetic energy generated by the effect of
air currents, and is transformed into other use-
ful forms for human activities.

19. Marine energy
● Marine energy refers to the energy carried
by ocean waves, tides, salinity, and ocean
temperature differences.

20. Geothermal energy
● Geothermal energy is thermal energy
generated and stored in the Earth. Thermal
energy is the energy that determines the
temperature of matter.

21. Biomass
● Biomass, as a renewable energy source, is
biological material from living, or recently
living
organisms. As an energy source, biomass
can either be used directly, or converted into
other energy products such as
biofuel.

22. Non-renewable energy
● Nuclear energy
● Coal
● Petroleum
● Natural gas

23. Nuclear energy
● Nuclear energy usually means the part of
the energy of an atomic nucleus, which can
be released by fusion or fission or
radioactive decay

24. Coal
● Coal is a combustible black or brownish-black
sedimentary rock usually occurring in rock strata
in layers or veins called coal beds or coal seams.

25. ● Petroleum or crude oil is a naturally
occurring, flammable liquid consisting
of a complex mixture of hydrocarbons
of various molecular weights and other
liquid organic compounds, that are
found in geologic formations beneath
the Earth's surface.
Petroleum

26. Natural gas
● Natural gas is a naturally occurring
hydrocarbon gas mixture consisting
primarily of methane

27. Wind turbine creates water from thin air
● Eole Water have invented a new type of eolic
turbine that produce drinking water from humid
air.
● A turbine can produce, filter and purify the water
up to 1,000 litres of drinking water every day.
● This is a solution clean and sustainable way to
provide water to isolated rural communities, in
Africa and South America as well as remote
islands in Asia but nowadays is a expensive
solution.
