Photovoltaic technology converts sunlight into electrical energy through photovoltaic (PV) modules or mirrors that collect solar radiation. This energy can be used to generate electricity or stored in batteries or heat accumulators. Wind turbines work on a simple principle. Instead of using electricity to create wind like fans do, wind turbines use wind to create electricity. The wind spins blades like a turbine propeller around a rotor, turning a generator to generate electricity.
