Energy Demands

Question 1

biofuel power stations

Answer 1

carbon neutral, renewable, cheap, not as efficient as coal

Question 2

nuclear power stations

Answer 2

uranium atoms split, energy transferred by coolant turning water to steam, no carbon emissions, reliable, not renewable

Question 3

wind turbines

Answer 3

blades capture wind kinetic energy, have to be in farms to produce significant electricity, eye sore, unreliable, no carbon emissions

Question 4

wave power

Answer 4

oscillating tower of water and air producing 500kW electricity

Question 5

hydroelectric power

Answer 5

electricity generated from kinetic energy of moving waters reliable

Question 6

solar

Answer 6

sun’s energy heats water in heating panels, renewable, convenient, low energy, wildlife nesting

Question 7

tidal power

Answer 7

high tide travels through turbines turning generator, underwater cable connecting to national grid

Question 8

solar power stations

Answer 8

sun’s energy reflects of heliostats onto boiler, water to steam, not a lot of energy produced

Question 9

geothermal energy

Answer 9

harnessing of radioactive decay underground by capturing steam from nearby water of geothermal rocks, reliable, inconvenient
