Energy Resources

Question 1

Explain what is meant by the term CCS (capture carbon storage)

Answer 1

Thsi is a way of stopping c02 getting into the atmosphere and polluting it, old plus and fuel can be used for storage,

Question 2

Give to advantages of using nuclear power to supply energy rather than coal.

Answer 2

It doesn’t produce pollutant gases and more bevy is produced per kg of fuel

Question 3

List 7 energy sources

Answer 3

Solar
Wind
Biomass
Geothermal 
Hydroelectric 
Tidal
Wave

Question 4

Describe solar energy and what it does/ how it works

Answer 4

• it comes from the sun
• the heat and light turns into electrical energy by solar cells
• it’s free, no waste/pollution, renewable
• doesn’t work at night, expensive to buy, in less sunny places won’t work

Question 5

Describe wind energy and what it does/ how it works

Answer 5

• energy comes from the wind
• the sun heats the atmosphere and leaves patches that are warmer, these rise and air blows to replace gaps, causing wind which turns a generator.
• wind is free, renewable, no waste: pollution
• isn’t always predictable, expensive, interfere tv connections, noisy, kill wildlife

Question 6

Describe biomass energy and what it does/ how it works

Answer 6

• from organic materials being burnt.
• biomass plant burns materials (eg wood) creating energy.
• renewable, good use of waste materials, cheap.
• collecting/ growing fuel can be difficult in large quantities, not available all year round?

Question 7

Describe geothermal energy and what it does/ how it works

Answer 7

• from within the earth, near heated places.
• power plants tap into hot reservoirs underground, renewable heat is used to drive an electrical generator.
• no pollution, doesn’t contribute to greenhouse gases, no fuel is needed and power stations are small.
• not many suitable places to build them.

Question 8

Describe hydroelectric energy and what it does/ how it works

Answer 8

• from running water
• Dan is needed, water files through tunnels and turns turbines that drive generators to produce electricity.
• once built energy is free, no waste/pollution, can be constantly generated.
• building Dan will flood upstream, damage wildlife and could cause obstruction to public

Question 9

Describe tidal energy and what it does/ how it works

Answer 9

• from the earths ocean movement.
• tidal Barriers leaves little space for water to get through which turns a turbine creating energy.
• once built is free, no pollution/ waste, tides are predictable, not expensive to maintain.
• few suitable locations, only provide energy 10 hours a day

Question 10

Describe wave energy and what it does/ how it works

Answer 10

• from waves being blown across the sea.
• works like swimming pool wave machine.
• energy is free, no pollution, not expensive to maintain, produces lots of energy.
• must withstand all weather, must be suitable site and can produce wide range of energy due to different waves.
