GREEN ENERGY....ITS JUST A NEW WAY???

The sources are categorized as follows:

• Conventional or non-renewable energy is the energy which can not be renewed for a reasonable human time. Usually, the formation process, when it is repetitive, requires millions of years. Non-renewable energy sources include:

The solid fuel coal (lignite, peat, anthracite, etc.)

1. The liquid fuel, which is usually finished oil products (fuel oil, diesel, gasoline, kerosene, etc.)
2. Gaseous fuels (natural gas, LPG, etc.)
3. Nuclear energy from fission of radioactive materials (ouranio, plutonium, etc.)

• Renewable energy:
Are energy sources that are available over time, either because it is practically inexhaustible, either because renewed in due time through natural processes. Renewable energy sources include:

1. Solar energy

2. Wind Energy
3. The energy of waterfalls, sea currents and tides (hydraulic)
4. Biomass energy that all plant products
5. Geothermal energy, energy that is coming from inside the earth

• Renewable energy:
Are the sources whose use can be made with respect to the environment. Mild forms of energy does not coincide with renewable. For example, the use of biomass causing pollutants, while the hydropower plants are often destroyed the ecosystem of sites that work.
The ideal is therefore a source of energy would be mild and renewable, with low operating costs, negligible environmental impact and low technology necessary for its operation.
Pros and cons of wind energy

In recent years the great growth of wind power in our country has been accompanied by concerns of local communities in the impact it may have to install a wind farm in their area. The advantages and disadvantages of using wind energy are given below:

Advantages of using wind energy

Ø The wind is an inexhaustible source of energy, which also provided free.

Ø It pollutes the environment with hazardous air pollutants such as carbon monoxide, sulfur dioxide, carcinogenic particles, etc., in contrast to conventional power plants.

Ø It is a technologically mature, economically competitive and environmentally friendly energy option.

Ø Helps decentralized energy system by reducing transmission losses.


Disadvantages of using wind energy

Noise.

Beauty charge of the landscape.

Electromagnetic harassment in telecommunications, radar, television, etc.

Generally it should be noted that the benefits of using wind energy both locally and globally to outweigh any disadvantages to the development of technology increasingly restricted. The wind is now competitive with other fuels in areas with high wind potential, it is estimated that by 2012 will be fully competitive with the purely economic sense.
