Wind energy is green energy! Wind turbines use wind energy, which is created by atmospheric heating from the sun, to generate electricity. Using the advantages of wind energy we can convert the inexhaustible supply of wind to electricity without creating additional greenhouse gases and other pollutants.
Wind Energy Advantages
- Wind energy is free.
- The wind is a renewable supply and cannot be exhausted.
- Converting wind energy into electrical energy doesn’t create any greenhouse gases or add chemical pollutants to the environment.
- Wind turbines can be installed in remote locations where other forms of energy generation may not be practical.
- Wind turbines cost less and require less space than solar panels (PV) per kilowatt generated (if placed in a proper area).
Additionally, wind turbines may also be aesthetically pleasing for some people and in a few cases have generated a small amount of tourism.
Wind Energy Disadvantages
It wouldn’t be fair to list all the wind energy advantages without mentioning some of the disadvantages.
- The wind is not always constant or predictable causing the energy created from wind turbines to be less reliable than other energy generation technology.
- Almost all wind turbines create some form of noise pollutions, the large commercial VAWT will create a high frequency noises (still within human hearing). Large commercial wind turbines are not generally placed next to homes though. The smaller wind turbines make a much louder noise, similar to an airplane.
- Wind turbines have a higher upfront cost than other energy generation technology.
- Protestors normally confront wind turbine/wind farm construction for a few practical reason and dozens of silly reasons.
