How do wind turbines work

They have a generator
As the wind spins, it turns the generator
Converting kinetic→electrical

Where is the energy transported to

National grid

What are solar power generated by

Where do solar cells get their electrical current from

Sunlight

What appliances do solar cells work well in

Watches
Calculators
Remote areas

What are the advantages of wind and solar energy

Process of making them produces pollutants
Dependent on the weather
No way to increase supply in demand
Take up a lot of space
Wind turbinwes are too noisy
