Name two advantages of wind power

Answer 7

Can be installed offshore, and no fuel is needed

Question 8

Name two advantages of tidal power

Answer 8

Predictable source, can double up as protection against flooding

Question 9

Name two advantages of wave power

Answer 9

No waste products, no harmful gases released

Question 10

Name two advantages of geothermal power

Answer 10

The hot water produced can also be used to heat homes, and it is not dependent on weather conditions

Question 11

Name an advantage of biogas

Answer 11

Uses waste products - biodegradable matter

Question 12

Name two advantages of coal, oil and gas

Answer 12

Creates lots of jobs, cheap

Question 13

Name two advantages of nuclear power

Answer 13

For the amount of fuel used, a lot of electricity can be produced and it is clean.

Question 14

Name two common advantages to renewable sources of electricity.

Answer 14

No fuel is needed and they are clean

Question 15

Name two disadvantages of hydroelectric power

Answer 15

Takes up lots of space and could cause flooding

Question 16

Name two disadvantages of solar power

Answer 16

Not very efficient, they only work during the day

Question 17

Name two disadvantages of wind power

Answer 17

Depends on strength of wind, can cause environmental damage

Question 18

Name two disadvantages of tidal power

Answer 18

Construction can be costly and only works twice a day

Question 19

Name two disadvantages of wave power

Answer 19

Can disrupt fishing and shipping, and only small amounts of electricity are produced

Question 20

Name one disadvantage of geothermal power

Answer 20

Can’t use it everywhere, only specific locations

Question 21

Name a disadvantage of biogas

Answer 21

Limited supply of material to burn, non-renewable

Question 22

Name two disadvantages of coal, oil and gas

Answer 22

Finite, produces carbon dioxide and sulfur dioxide

Question 23

Name two disadvantages of nuclear power

Answer 23

Radioactive waste takes many years to decay - risk of accidents, and it costs a lot of money to decommission a nuclear power station
