| Question | Answer |
| chemical energy | The kind of energy stored in chemicals. Food, fuels and cells (batteries) all contain chemical energy. |
| coal | A fossil fuel made from the remains of plants. |
| electrical energy | The kind of energy carried by electricity. |
| fossil | A dead organism that has been trapped in mud and whose body has not completely rotted away. |
| fossil fuels | Coal, oil and natural gas – all fuels that were formed from the remains of dead plants and animals. |
| fuel | Anything that stores energy that can be converted into heat energy – includes fossil fuels and nuclear fuel. |
| generate | Make electricity by turning a magnet inside coils of wire. |
| heat energy | The hotter something is, the more heat energy it has. |
| kinetic energy | The kind of energy in moving things. |
| law of conservation of energy | The idea that energy can never be created or destroyed, only changed from one form into another. |
| light energy | The kind of energy given out by light bulbs, candles, etc. |
| natural gas | Fossil fuel formed from the remains of dead plants and animals that lived in the sea. |
| nuclear energy | Energy stored inside the particles that things are made out of. |
| oil | Fossil fuel formed from the remains of dead plants and animals that lived in the sea. |
| sound energy | The kind of energy made by anything that is making a noise. |
| uranium | A fuel used in nuclear power stations. |
| non-renewable energy resource | Any energy resource that will run out and we cannot renew our supplies of it (e.g. oil). |
| alternative energy resources | Another name for renewable energy resources. |
| biomass | Any fuel that comes from plants, animals, or their wastes (e.g. wood, methane from rotting plants, etc.). |
| generator | Large coil of wire with a magnet inside. When the magnet is turned, electricity is produced in the coil of wire. |
| geothermal power | Making electricity using heat from hot rocks underground. |
| hydroelectric power | Making electricity by letting falling water (usually from a reservoir) turn turbines and generators. |
| nuclear energy | Energy stored inside the particles that things are made out of. |
| radiation | Dangerous particles and energy given off by uranium and other radioactive materials. |
| renewable energy resource | An energy resource that will never run out (e.g. solar power). |
| solar cells | Flat plates that convert light energy into electrical energy. |
| solar panels | Flat plates that use the Sun's energy to heat water. |
| solar power | Making electricity by using light or heat energy from the Sun. |
| turbine | The machine in a power station that is pushed round by water or steam and turns the generator. |
| uranium | A fuel used in nuclear power stations. |
| wind turbine | A kind of windmill that generates electricity using energy from the wind. |
| joule (J) | The unit for measuring energy. |
| kilojoule (kJ) | There are 1000 joules in 1 kilojoule. |
| convection current | A flow of liquid or gas caused by part of it being heated or cooled more than the rest. |
| geothermal power | Making electricity using heat from hot rocks underground. |
| hydroelectric power | Making electricity by letting falling water (usually from a reservoir) turn turbines and generators. |
| nuclear power | Making electricity by using the nuclear energy stored inside uranium. |
| photosynthesis | Process that plants use to make their own food. It needs light to work. Carbon dioxide and water are used up. Food (a sugar called glucose) and oxygen are produced). |
| tidal power | Making electricity using the moving (kinetic) energy from the tides. |
