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.

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.

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

Disadvantages

Low 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:
