Question 13

What is wind?

Answer 13

is simply air that is moving. It is produced as different types of land and water absorb the Sun’s energy at different rates. Can be used to generate electricity using wind turbines.

Question 14

can be harnessed by large blades on wind turbines, which use it to generate electricity for residential and commercial purposes.

Answer 14

Wind Energy

Question 15

• is heat and light that comes from the sun’s rays. This is known as radiant energy, because the sun radiates (or sends out) a huge amount of this energy every day.
• Comes from the sun. It’s the primary source of energy for all living things on Earth, and can also be converted into electricity through solar cells.

Answer 15

Solar Energy

Question 16

when sunlight is turned into thermal energy, or heat. Most solar thermal systems use solar energy to heat up space or water. An example of this is a solar hot water system.

Answer 16

Solar Thermal

Question 17

when sunlight is converted directly into electricity, using photovoltaic cells. For an example of a PV system, just look up – the solar panels on the roof of your school are using PV cells to generate electricity right now!

Answer 17

Solar photovoltaic (PV)

Question 18
