We can use wind as a renewable energy source to give electricity. Wind turbines are built in areas with high speed winds and convert this kinetic energy of wind into useful electrical energy. They do this as the wind rotates the blades of the wind turbines and in turn powers an inductor generator to produce electricity by electromagnetic induction. The electricity produced can then be distributed via the National Grid, with wind power contributing to up to 20% of the UK’s energy demand.

Since wind is natural, it will not run out and therefore is a renewable energy source. Although the construction of wind turbines is expensive, once built, operational costs are low. However, obviously we cannot guarantee wind as the weather fluctuates from day to day, even in the windiest areas. For this reason, wind power can be labelled unreliable, but if enough wind turbines are built in a variety of areas, we can increase the reliability as it is likely that there will be enough wind in at least a few of these areas. It is a clean and environmentally friendly source of energy and therefore is becoming more widely used as alternatives to fossil fuels are sought after.
