WIND ENERGY

The energy made from the wind

What is Wind energy?

Wind energy is a renewable energy source. Wind energy harness the power of the wind which is found in moving air. Wind is created by the uneven heating of the surface and the atmosphere by the sun. So technically wind is made from the sun.

Economic Advantages

  1. Newer technologies are making wind energy much more efficient. The wind is free, and we are able to cash in on this free source of energy.
  2. The potential of wind power is enormous, the worldwide potential of wind power is more than 400 TW (terawatts).
  3. Remote areas that are lacking of energy supply or not connected to the electricity power grid can use wind turbines to produce their own supply of energy.


Economic Disadvantages

  1. Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100 000 people?
  2. Can affect television signals if you live nearby.
  3. Good areas for wind farms are near coastal area where land is expensive.

Environmental Advantages

  1. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants and to be eco friendly.
  2. Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy.
  3. Wind power is renewable and there is no way we can run out of it (since wind energy originates from the sun).


Environmental Disadvantages

  1. When wind turbines are being manufactured some pollution is produced. Therefore wind power does produce some pollution
  2. Wind is not constant causing the production of energy to vary. this also means sometimes wind turbines can't produce energy at all.
  3. Can kill birds.
