give one advantage and disadvantage of using a photocells to generate elecricity.
Advantage- no moving parts no power cables you wont run out disdadvantages- no sun no fuel
1 of 5
explain how wind turbines convert energy from the sun to electricity
energy from the sun heats the atmosphere which causes convection currents which produce wind. Wind turbines convert the kenetic energy of moving air intoelectricity. The wind turns the blades whitch turn a genorator.

breifly describe how a powerstation works.
the aim of a powerstation is to convert one ind of energy into electricity.
