WIND ENERGY

                       Wind Energy

                              How it Works

Wind is created by the uneven heating of air masses in the atmosphere. It can be harnessed in wind turbines. A group of wind turbines is referred to as a wind farm. The wind hits the turbines and makes them spin. This mechanical energy is then transferred into electricity. Wind can not be seen, but you can tell that the wind is blowing when you see the windmills spin.

                        What it is Used For

It is used to generate electricity for homes and businesses. When there is no wind, the generated electricity can be stored in rechargeable batteries. Wind energy is a renewable energy source, and can never run out.

                Advantages and Disadvantages

Like all great things, there are some big disadvantages that come along with it. First, the cost. It costs lots of money to build the turbines. Second, sometimes there is no wind. If we depend entirely on wind energy, one day, there could be hours, even days, when there was no electricity at all due to the fact that there was no wind. Some great things about this resource are that is renewable, meaning that it will never run out and can be replenished in a lifetime. Secondly, it is more Eco-friendly than some of the other resources. It does not harm the wind or living creatures in any way.

This is how the Wind Turbine works.

Wind turbines are grouped together in WIND FARMS.
