Energy Resources

A coal-fired power station generates electricity. Coal is burnt and the energy released is used to

boil water. The steam from the water makes the generator move and this produces electricity.

Which 2 words are used to describe first the energy stored in the coal and secondly the energy of the moving generator?

• chemical, hydroelectric

• chemical, kinetic

• geothermal, hydroelectric

• geothermal, kinetic

Which energy source is one that is used to boil water to make steam in power stations?

• energy from tides

• energy from waves

• hydroelectric energy

• nuclear energy

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

• coal

• geothermal

• nuclear

• wind

Which energy resource generates electricity without any moving parts?

• geothermal

• hydroelectric

• nuclear

• solar

Which form of energy is used to generate electrical energy in a tidal power station?

• chemical energy

• gravitational energy

• internal energy (thermal energy)

• nuclear energy

In a hydroelectric power station, one form of energy is stored in a lake or reservoir. This energy is

then transferred in stages to another useful form, which is the output. Which row gives the name firstly of the stored energy and secondly the name of the output energy?

• stored electrical output thermal

• stored electrical output kinetic

• stored gravitational output electrical

• stored kinetic output electrical

Which group below are classed as fossil fuels?

• coal, oil, nuclear

• coal, solar, natural gas

• coal, nuclear, solar

• coal, oil, natural gas

Which of these renewable resources can be used during the day or night but is unreliable?

• Wind

• Solar

• Geothermal

• Pumped storage
