Wind energy systems

The blowing winds are a renewable energy source. The energy produced from winds is called wind energy. The systems that use renewable wind energy for different purposes are called wind energy systems and are becoming very popular because of several reasons. These systems harness the renewable wind energy so that it can be used for a number of applications. These systems can be used as an alternative for fossil fuels. This is because the use of fossil fuels causes pollution and increases global warming whereas wind energy systems do not cause any pollution. Once the availability of fossil fuels comes to an end, these systems will be the only alternative energy source that will be able to meet the energy requirements.

These systems can be either used along with grid connected systems or as stand alone units. The wind energy systems when used along with grid connected systems continue supplying power for most of the time and if the amount of energy generated is insufficient to meet the energy requirements the utility grid supplies the required energy. The switching over between the wind energy system and the utility grid is automatic

The stand alone wind energy systems can be used to meet the energy needs of homes, farms or small communities.

Both types of wind energy systems generate electricity that can be used as an alternative power source in houses and industries. They result in a significant reduction in costs incurred in generating energy. These systems can provide cost effective, clean and renewable wind energy for many years.
