WHAT IS IT? Its a kinetic energy. Wind turbines are used to produce eolic
energy.
ADVANTAJES Its a renewable energy Wind turbines have low cost High perfomance is achieved Reduce energy dependency on fossil
fuels.
DISADVANTAJES Intermittent and random Difficul storage Wind turbines are danger to birds occupy large tracts of land generate interference
PERCENTAGES Spain= 16% power consumption In the world= aproximate 20%
Coal
By: Leandro Domínguez, Pablo Vizcaíno and Andrea Medina.
Vegetable remains like anthracite, coal, lignite and peat.
Consist in:
Advantage:
Cheap power and with hight energy power.
Disadvantage:
Very pollution.
.
% used in the world:
39
In Spain: 15

OIL
What is the oil?It is the most used energy source. As fuel is more efficient than coal, it has higher calorific
Adventage :It has an easy obtainment.It is very useful.It is a quite effective energy.
Disadventages:It is very contaminating.Produces highly toxic substances such as CO2.
Ocean pollution.

THE END
HIDROPOWER
HYDROELECTRIC PLANT IS TO OBTAIN ENERGY FROM THE WATER STORED
IN THE DAM.
ADVANTAGES AND DISADVANTAGES
ADVANTAGES: HAVE MINIMUM MAINTENANCE, CLEAN DOES NOT GENERATE WASTE AND HELP CONTROL FLOODS AND PROVIDE WATER FOR AGRICULTURE.
DISADVANTAGES: THEY ARE FAR FROM LARGE TOWS AND WATER QUANTITY DEPENDS ON TIME, THE CONSTRUCTION OF RESERVOIS INVOLVES THE
FLOODING OF THE DAM.
IN SPAIN, 75% OF THE POPULATION USES THIS ENERGY AS THAT IN THE
WORLD ONLY 14%.

WHAT IS IT?It is the energy that comes from heat stored in the Earth's interior.
ADVANTAGE•It produces no waste.•It is inexhaustible on a human scale.
•In some countries is to restore use it to produce electricity
DRAWBACKS•The location is difficult.•It’s very costly.
IN SPAIN ANDIN THE WORLD
•With regard to renewable energy:•In Spain: 0.05% is used.•In the world: 0.8% is used
biomass
advantajes
• It produce little waste
• They are low-polluting
• Much of the waste is from human activities
DisadvantagesLow efficiency energy
• It has big volume (hindering manipulation)
It`s produced
:3 Forms:-agricultural crop
-recycling waste
-Chemically transforming plants
Natural gas
A source of energy
is a mixture of gases
advantage disadvantages The use of natural gas
produced many greenhouse gases are damageable by weather• Natural gas is not a renewable energy source.• It is difficult to store natural gas
• can replace coal and oil• as heating• as fuel• produces electricity• high calorific• clean combustion
Spain spends 21 % of gas In world spends 56% of gas
All the gas becomes exhausted:
