In which pair of energy sources are both sources renewable?

• oil and coal

• oil and tidal

• tidal and geothermal

• tidal and nuclear fission

A tidal power station is made by building a barrage across the mouth of a river. At high tide the

sea water is trapped behind the barrage.

At low tide the water is allowed to flow back into the sea through a turbine.

What is the useful energy change in a tidal power station?

• electrical energy → energy of position (potential)

• electrical energy → energy of motion (kinetic)

• energy of motion (kinetic) → energy of position (potential)

• energy of position (potential) → electrical energy

Which energy resource is used to generate electricity by first boiling water?

• hydroelectric

• nuclear fission

• tides

• waves

Which statement correctly compares the production of electricity using wind and the production of

electricity using nuclear fission?

• Wind is less reliable than nuclear fission; both wind and nuclear fission are renewable.

• Wind is less reliable than nuclear fission; wind is renewable, but nuclear fission is not.

• Wind is more reliable than nuclear fission; both wind and nuclear fission are renewable.

• Wind is more reliable than nuclear fission; wind is renewable, but nuclear fission is not

Which energy source is renewable and reliably available at all times?

• coal

• geothermal

• nuclear

• wind

The list contains three energy resources P, Q and R.

P geothermal energy from hot rocks

Q nuclear fission in reactors

R sunlight on solar panels

Which of these resources are renewable?

• P and Q only

• P and R only

• Q and R only

• P, Q and R

Energy resources are used to generate electricity.

Which resource is renewable and does not release carbon dioxide when being used to produce

electricity?

• biomass
