The most dangerous threat to the world is the degradation of environment. Various factors have led to these threats like cutting of trees, use of harmful chemicals, use of fuels etc. Let’s throw some more light on the term harmful fuels. These fuels are used for generating energy but in the process of doing so they emit various harmful gases as well as materials that are harmful for nature as well as for human beings. The most common function of these fuels is to generate electricity. Seeing the hazards of such fuels, various other alternatives have evolved, wind energy being one of them. Wind energy can be described as a form of energy that is generated from wind. This form of energy is available in abundance and is highly renewable. It is highly eco-friendly and thus promotes the greenhouse effects. The conversion of wind energy into various other forms that can be used is known as wind power. Wind energy is converted into wind power with the help of wind turbines. In whole world around 1percent of electricity is generated with the help of wind energy. In Denmark, wind energy constitutes around 20 percent of energy. The only drawback of wind energy is that it varies from time to time as the speed of wind does not remain same always. There are various advantageous of wind energy that is listed below.
