This document provides an overview of different types of energy. It discusses energy definitions and measurements. It describes various forms of energy including mechanical, electrical, electromagnetic, sound, chemical, nuclear, and thermal energy. It distinguishes between renewable energy sources like solar, wind, hydraulic, and biomass versus non-renewable sources like coal, petroleum, and natural gas. The document also examines environmental impacts of energy production and discusses different types of energy power stations including nuclear, thermal, hydro, solar, and wind turbines.

3. ENERGY DEFINITION
Energy is the capacity of an object of doing a
work.
All objects need energy to work
Energy is measured in calories and joules.
To measure larger quantities we use kcal and kJ.
1 cal = 4.18 J

4. TYPES OF ENERGY
MECHANICAL ENERGY
Kinetic energy: It is the energy related to
movement.
Potential energy: It is the energy related to the
posititon of the objects.

5. ELECTRICAL
ENERGY
It is the energy related
to an electric current.
Thanks to this
energy, machines
connected to sources
of electricity work.

6. ELELECTROMAGNETIC ENERGY
It is the energy transported by
electromagnetic fenomena. Luminous
energy is a type of electromagnetic
energy.

7. SOUND AND CHEMICAL ENERGY
SOUND ENERGY: CHEMICAL ENERGY:

heat stored in the earth's crust.

17. ENERGY POWER STATIONS
Energy comes in different forms. The most usual
is electrical energy. It is easy to generate, and it
can also be generated through a lot of different
ways by varied types of power plants. Although
the word 'generated' is commonly used with the
word 'energy', it is a fact that energy cannot be
generated or destroyed. We can just change
the form of energy. At power plants too, energy
that is available in a particular form is converted
into another form.

20. ENERGY POWER STATIONS
WIND TURBINES: Wind turbines are used to generate
electricity from the kinetic energy of the wind.
However, a French engineering firm has recently
discovered another way of using this turbines.
By this method, the turbines can manufacture drinkable
water from humid air.
Is this process is developed, turbines will allow some
isolated areas to be self-sufficient,because one turbien
can produce 1000 litres a day
For the moment, it is too expensive,but as time passes,it will
have a more reasonable prize.
