Answer 19

Photovoltaic cells
and
Solar thermal energy

Question 20

Sunlight is focused on a fluid that boils to spin a turbine to generate electricity

Answer 20

Solar Thermal Systems

Question 21

Sunlight can be used to save energy without even generating electricity

Answer 21

Passive Solar Heating

Question 22

can save money by heating or lighting buildings passively.

Answer 22

Solar Energy

Question 23

No pollution and is renewable. Dams hold large amounts of water back. Water flowing through forces turbines to spin and create electricity.
