Alternate sources of energy like wind energy help in effectively curtailing the consumption of non renewable energy for various purposes whether it’s domestic, agricultural or industrial.
The domestic usage of wind energy is effective only to feed the energy appliances that consume a very little amount of energy. For appliances that consume more energy, an expensive windmill will be required. The water heaters and television sets require more energy. Hence a little wind power may not be very effective in satisfying these demands. Wind power is mostly effective only in satisfying a part of the demand or only as a substitute.
