Potential and prospects of wind energy

Wind energy is the form of renewable energy that we get from the blowing wind. Wind blows because of the uneven heating of the earth’s surface by the sunlight. This blowing wind possesses kinetic energy that can be harnessed to generate electricity. Wind turbines are wind machines that convert the wind energy into electricity. This can be used for both domestic and commercial purposes. Wind turbines have rotors that move because of winds. The rotors are connected to generators that are turned on by the movement of rotors. The generators produce electricity.

The potential of wind energy as an alternative source of energy is increasing rapidly. A major factor responsible for this is the fact that wind energy is a clean and non polluting source of energy. Wind energy does not emit any greenhouse gases that cause global warming. Also wind energy does not add toxic elements to the atmosphere. It can be used as an alternative source of energy because the conventional sources of energy are fast depleting and their prices are sky rocketing. The energy crisis so created can be challenged by wind energy.

Wind energy technologies have seen a change over the years. They now produce a significant amount of wind power for the entire world. The global prospects of wind energy are on the rise. Wind energy technologies are used all across the globe for cost effective power generation. The amount of electricity produced by wind energy is so enormous that even if electricity is not produced by conventional methods, it would be sufficient enough to provide power to the generations to come.
