Question 0

Renewable energy source

Answer 0

A energy source that will not run out

Question 1

Non renewable energy source

Answer 1

An energy resources that effectively cannot be replaced once it has been used

Question 2

Energy change in a turbine and a generator (4)

Answer 2

Stored energy is use to heat water
Heat energy in high pressure steam drives the turbine
Kinetic energy of the turbine spins the generator
Electricity is produced

Question 3

Hydroelectric power

Answer 3

GPE of water in dams turn a generator
Water evaporates back into the redo our so it is renewable
Clean but ruins landscape and wildlife

Question 4

Tidal power

Answer 4

GPE of tides turns a generator
Renewable
Not many places where a tidal power station can be built

Question 5

Wave energy

Answer 5

Waves push air in a column to turn a generator
Falling water will suck air from the column, thus turning the generator on the way back
Renewable
Clean

Question 6

Wind energy

Answer 6

Heat energy from the sun causes wind to occur and turns the generators
Renewable 
Clean
Doesn't convert much energy
Ruins landscape
Causes noise pollution

Question 7

Solar power

Answer 7

• Solar cells convert light energy into electrical energy
  Renewable
  Expensive and need bright lights
• Solar heating panels heat copper water pipes that heat water
  More cost efficient

Question 8

Geothermal energy

Answer 8

Uses heat energy from the earths core for heating
Renewable
No pollution
Reliable
