Sound EnergyIn the United States, nonrenewable energy sources supply most of the energy we use. 

Underground Mine:

 

underground or a cave.

 

Open Sky:

Outdoor.

 

What are the energy sources?

They are natural resources that Through their transformation they allow to obtain energy

 

 

 

ALTERNATIVES

 

They are used little in the search phase, the solar, the wind, the geothermal and the mareomotive.

 

TRADITIONAL:

 

They are the most used, coal, oil, natural gas, uranium and hydraulics

 

 

 

NON-RENOBULABLE ENERGY SOURCES

 

- CARBON:

It is a fossil fuel, decomposition of accumulated vegetables and grazed for millions of years.

 

ADVANTAGES: it is transformed easily, it is a fuel to produce thermal energy, abundant reserves

 

DISADVANTAGES: Greenhouse gases, acid rain, impacts, extraction, transport, mines.

 

 

 

- PETROLI:

It is a fossil fuel, with great calorific power, raw material and crude oil.

 

ADVANTAGES: Easy to extract, energy resources, produce electricity, Raw material, fuel and the most widely used energy source.

 

DISADVANTAGES: there are not enough reserves, it is consumed at a dizzying rate, it is Contaminated, black tides.

 

 

 

- NATURAL GAS

: Origin similar to petroleum, electricity fuel, mainly Methane, raw material, consumes

 

ADVANTAGES: Contaminates less than others, raw material, consumption every time Increasingly

 

DISADVANTAGES: Non-Renewable, training for millions of years

 

 

 

 

NUCLEAR ENERGY

: Enriched uranium generates a lot of electricity

 

ADVANTAGES: Nuclear reactors, it does not release CO2

 

DISADVANTAGES: Nuclear accidents and waste

 

 

 

RENEWABLE ENERGY SOURCES

 

- HYDRAULIC:

The strength of the water

 

ADVANTAGES: it is not Contaminated, they are not exhausted

 

DISADVANTAGES: Large environmental impacts

 

- SOLAR OR PHOTOVOLTÀICA:

the sun emits inexhaustible radiation.

 

ADVANTAGES: no Contamina, it is not exhausted

 

INCONVENIES: Thermal variations

 

 

 

- Aeolian:

Wind force

 

ADVANTAGES: no Contamina, is not exhausted, it is renewable

 

DISADVANTAGES: Turbines alternate the landscape, can not be built everywhere.

 

- GEOTERMIC ENERGY:

ADVANTAGES: it does not pollute and it is not exhausted

 

DISADVANTAGES: We need large extensions in volcanic areas

 

 

 

- MAREOMOTRIU:

ADVANTAGES: Marine currents, very strong waves

 

DISADVANTAGES: the Installations

 

 

NATURAL GAS
 

Advantages 

• Burns clean compared to cola, oil (less polluting) 

• 70% less carbon dioxide compared to other fossil fuels 

• helps improve quality of air and water (not a pollutant) 

disadvantages

• not a renewable source 

• finite resource trapped in the earth (some experts disagree) 

• inability to recover all in-place gas from a producible deposit because of unfavorable economics and lack of technology (It costs more to recover the remaining natural gas because of flow, access, etc.) 

NUCLEAR POWER 

Adventatges

• Clear power with no atmospheric emissions 

• Useful source of energy 

• Fuel can be recycled 

Desavantatges

• Potential of high risk disaster (Chernobyl)

• Waste produced with nowhere to put it 

• Waste produced from nuclear weapons not in use 

 

One advantage of diesel is that it is a potent fuel.

disabentatges of gasoil is:

One disadvantage of diesel is that it is very bad for the anvient.
