3
How is wind energy formed? Wind is caused by the uneven heating of air causing convection currents. Turbines use blades to collect the wind’s kinetic energy.
4
Benefits Clean No air or water pollution Wind is free! Domestic wind turbines are relatively inexpensive to buy and installDomestic wind turbines Wind turbines don’t require a large area of space even when of an industrial size. This allows the land beneath to be used, for example, for agriculture Excess electricity can be sold to energy companiessold to energy companies
