• wind power
• wave power
• hydroelectric power
• tidal power

Question 2

How are these energy resources used?

Answer 2

• electricity generator on top of a tall building
• waves generate electricity by turning a floating generator
• hydroelectricity generators are turned by water running downhill
• a tidal power station traps each high tide and uses it to turn generators

Question 3

Power from sun and earth

Answer 3

• solar cells are flat solid cells and use the suns energy to generate electricity directly
• solar heating panels use the sun’s energy to heat water directly
• geothermal energy comes from the energy transferred by radioactive substances deep inside the earth
• water pumped into hot rocks underground produces steam to drive turbines at the earths surface that generate electricity
