ENERGY
Energy is defined as the capacity of performing changes
It allows almost everything in the Universe to happen
NON - RENEWABLE ENERGY
● Oil
● Coal
● Natural Gas
● Nuclear Fission Energy
By non-renewable energy we mean those kinds of limited sources of energy that can not be replaced when they are completely used up.
OIL
Advantages:● It is easy to manage and
its use is well organized.
Disadvantages:● It contaminates when is
produced, transported or used.
● It releases CO2
● It causes acid rainhttp://www.educapoles.org/swf/animations_loader.swf?path=/uploads/flashanims_files/energy_10_oil_061211.swf
COALAdvantages:
● Deposits are usually on the surface which makes it easy to remove and transport
Disadvantages:● Its extraction generates a
significant degradation of the landscape
● It produces too much CO2
● It causes acid rain

NATURAL GASAdvantages:
● It doesn’t produce acid rain
Disadvantages:● High installation cost
● High CO2 emissions and fuel consumption

NUCLEAR ENERGY
Advantages:
● High energetic output. ● Low atmospheric
contamination.
Disadvantages:● Radiactive residuals.● Detailed protocol program is
required.● An accident may have terrible
consequences.

RENEWABLE ENERGIES
● Solar● Wind● Minihidraulic● Tidal wave● Geothermal● Biomass
They are energies which are constantly renewed. It doesn’t mind what they are used far, and they always keep the same level of energy.
SOLARAdvantages:
● It does not use petrol
● It does not produce much residuals
● CO2 emission and enviromental impact are reduced
● The sun is free
Disadvantages:
● The location must be in a place with high solar radiation
● Less developed than other systems
● It is dangerous because of the high temperatures it reaches

WINDAdvantages:
● It does not produce pollution
● It is a safe and renewable source of energy
● It doesn’t release CO2 emissions and it doesn’t generate residues
Disadvantages:
● It depends on atmospheric conditions
● The transformation towers modify the landscape and produce a high level of acoustic contamination
● A lot of birds die when they crashed into the windmill spades

WAVE ENERGY
Advantages:● Low level of pollution● It is avaliable in any
climate and epoch of the year
Disadvantages:● Visual impact on the
coastal landscape● Punctual location● High cost
MINIHYDRAULIC
Advantages:
● It is a renewable and clean energy that even works at night
● Low cost. It doesn’t use fuel
Disadvantages:
● Landscape must be modified
● Need of flooding a large extension of land that forces people to move from their home

GEOTHERMAL ENERGYAdvantages:
● No acoustic contamination
● This energy doesn’t produce too much residuals
● This system allows us to save a lot of money
Disadvantages:
● Water is contaminated with substances as ammonia and arsenic
● It produces thermal pollution
● This energy damages landscape

BIOMASS
Advantages:
● You can use biomass fuel for a lot things
● The CO2 released in biomass’combustion has been previously fixed in plant growth, with a very favorable balance
Disadvantages:
● The plant construction causes alterations in the natural environment
● Getting a good energy supply needs a large amount of biomass
