How does solar work?

Solar energy comes from the sun in the form of photons. When photons enter solar cells, they bump into electrons and set them free. The freed electrons are then channelled into a current which we know as electricity. Which of the following is correct? *

1 point

Solar cells are also called photovoltaic cells

The most common cells are made of silicon and boron

1 in 7 homes have solar power

All of the above

How does a wind turbine produce energy? *

1 point

They pump up water which turns turbines that produce power

The blades are connected to a shaft which is connected to a generator

The rotating shaft creates its own electricity

Energy is harvested from the wind the turbines create

Wind turbines
