Index• Energy definition

• Types of energy

• Energy sources

• Renewable and non-renewable

• Enviromental inpact

• Energy power stations

• Energy is the capacity of a body to do a work.

• MECHANICAL ENERGY.

-Kinetic energy is the energy associated to the movements

-Pontential energy is the energy that objects have when they´re moved from their stable

position of equilibrium.

• ELECTRICAL ENERGY:The energy associated with an electrical current.

• ELECTROMAGNETIC ENERGY:Transported by electromagnetic waves,such as TV.

• SOUND ENERGY:Energy related to the sounds waves transmitted by vibrations.

• CHEMICAL ENERGY:Is stored in substances.

• NUCLEAR ENERGY:Is energy released during fission or fusion of atomic nuclei.

• THERMAL OR CALORIFIC ENERGY:

Is energy that comes from the vibrations of particles.

• Energy sources are natural resources that provide different forms os energy.

• NUCLEAR ENERGY:

• -Nuclear fussion is when two nuclei join fprm a heavier nucleus.

• Nuclear fission Iis when a heavy nucleus is divided into two smallers nuclei.

• COAL:

-Open-cast mines:Coal casts are outdoor

-Underground mines:Coal casts are inside the earth and we cannot se its.

• PETROLEUM:

-Oil tankers:Specialished ships designed for intercontinental transport.

-Oil pipelines.Enormous steel

Pipes.

·NATURAL GAS:

Is transported in longs tubes along parts of the earth.

• WORLD RESERVES OF FOSSIL FUELS:

• INCREASED GREENHOUSE EFFECT:

Some sun rights  bounce off the atmosphere and do not go.

• ACID RAIN: The rain mix with chemical products that spoil all that it touch.Here you have an example:

• OIL SPILLS:These happen when petroleum is accidently released into the sea.

• NUCLEAR WASTE:These are very dangerous rpoducts and you must take care with it becouse it can cause you chemical reactions.

• RISING WATER TEMPERATURE:These provoke,for example,the melting on the oceans

• ATMOSPHERIC POLLUTION:These occurs when gases are expelled to the atsmosphere.

• HYDRAULIC ENERGY:Is related with the water.Water is transform into energy.

• SOLAR ENERGY:Is related with the sun.Sun is transform into energy.

• WIND ENERGY:Is related to the wind.We transform the wind into energy.

• MARINE ENERGY:Several means

-Tidal energy

-Wave energy

-Ocean thermal energy

• GEOTHERMAL ENERGY:This energy comes from the heast stored in the earth’s crust.

• BIOMASS:Is produced from

Plants remains,forest and agricultural

Waste.

·MUNICIPAL SOLID WASTE:This is generated in cities.Comes from domestic activities.

• Possible adverse effects caused by a development, industrial, or infrastructural project or by the release of a substance in the enviroment.

• THERMAL POWER STATIONS:

• SOLAR POWER STATIONS:

• NUCLEAR POWER STATIONS:

• WIND POWER STATIONS:

• ELECTRIC POWER STATIONS:
