Energy Production

Question 1

Hydro electric

Answer 1

Pros - renewable, large amount of power for a low cost, no fuel cost, can have a secondary purpose e.g water reserve
Cons - expensive to build, can only be used in certain locations, may destroy habitat

Question 2

Biomas

Answer 2

Pros - renewable, waste from plants + farming can be used, doesn’t give off harmful chemicals
Cons - emits pollution, large areas if land are needed to produce the fuel

Question 3

Tidal

Answer 3

Pros - renewable, no emissions, tides are predictable, can have a second purpose such as a bridge
Cons - lower energy output that fossil fuels, can impact the environment, causes coastal erosion, expensive to build, only by coast

Question 4

Solar

Answer 4

Pros - renewable, no emissions, can be used anywhere
Cons - could change ecology, unpredictable output, expensive to start

Question 5

Oil

Answer 5

Pros - stable output, cheaper to start, easy to extract fuel
Cons - greenhouse emissions, will run out, mining destroys habitat, risks with mining

Question 6

Gas

Answer 6

Pros - stable output, large energy output, relatively cheap to extract fuel, cleaner than coal or oil
Cons - will run out, greenhouse emissions,

Question 7

Wind

Answer 7

Pros - freely available, renewable, can be used anywhere, no emissions
Cons - wind is inconsistent, if at sea it can restrict shipping lanes, visual and sound pollution, expensive to set up

Question 8

Bio diesel

Answer 8

Pros - renewable, waste from plants and farming can be used, doesn’t give off harmful chemicals
Cons - large areas need to cultivate crops, emits pollution

Question 9

Coal

Answer 9

Pros - reliable power output, large power output, cheap to extract
Cons - will run out, emits pollution, mining destroys landscape, risks of mining
