17
Q

What is Wave Power?

A

Wave Power is when the tide pushes air through a turbine which is connected to a generator, producing energy.

18
Q

What is the advantages of Wave Power?

A
  1. Renewable

2. No pollution

19
Q

What are the disadvantages of Wave Power?

A
  1. Needs alot of machines to get a reasonable amount of energy
  2. The machines can be damaged by storms
  3. The machines can cause visable pollution
20
Q

What is Tidal Power?

A

Tidal Power uses the flow of tides to generate electricity by spinning a turbine when the tide comes in and out which is connected to a generator, producing energy.

21
Q

What are the advantages of Tidal Power?

A
  1. Low running costs
  2. Reliable power source
  3. Renewable
  4. No pollution
  5. High power output
22
Q

What are the disadvantages of Tidal Power?

A
  1. Can destroy habitats
  2. Tidal range varies
  3. Expensive to build
23
Q

What is Geothermal Energy?

A

Geothermal Energy is when water is pushed down into the earth where it is heated by radioactive elements which turns the water into steam. This spins a turbine which is connected to a generator, producing energy

24
Q

What are the advantages of Geothermal Energy?

A
  1. 24 hour productio
  2. Reliable Power source
  3. No fuel required
  4. Long life time
  5. Renewable
  6. No pollution
25
Q

What are the disadvantages of Geothermal Energy?

A
  1. Expensive to build
  2. Only suitable in some places
  3. Cannot provide all power needs
26
Q

What is Solar Power?

A

Solar Power is when Solar Cells turn light energy from the sun directly into direct current electricity.

27
Q

What are the advantages of Solar Power?

A
  1. No pollution
  2. Energy is free
  3. Very good for remote locations
  4. No power lines
  5. Renewable
28
Q

What are the disadvantages of Solar Power.

A
  1. Very expensive to build
  2. Highly toxic materials
  3. Only work when it is sunny
  4. Low power output
  5. Low efficiency
  6. Manufacturing is polluting
29
Q

What is Global Warming?

A

Global Warming is where infrared radiation becomes stuck in the Earth’s atmosphere and heats up the earth. This is because CO² and other gases from fossil fuels rrap the infrared radiation, stopping it from leaving Earth’s atmosphere.

30
Q

What is Carbon Capture Storage (CCS)?

A

Carbon Capture Storage (CCS) is the process of capturing waste CO². The CO² is deposited somewhere, where it wont be released into the atmosphere. The aim is to prevent the release of large quantities of CO² into the armosphere.

31
Q

What is Energy Demand?

A

How much electricity is needed by the population of a country which can vary depending upon the time of day and time of year.

32
Q

Put (Coal, Gas , Oil) in order of increasing greenhouse emissions…

A
  1. Coal
  2. Oil
  3. Gas

1 - 3
Most - Least

33
Q

Which 2 energy sources are used to meet basic demand and which 2 enedgy sources are used to meet peaks / extra demand?

A

(Nuclear + Coal) are used to meet basic demand

Longest start-up times

(Oil and Natural Gas) are used to meet extra demand

Shortest start-up times

34
Q

Other than (Coal, Oil, Gas and Nuclear) how can we meet energy demands?

A
  1. A pumped storage scheme

2. Renewable resources (suitable weather conditions)
