National grid
The National Grid is the network of power stations, pylons and cables which supply electricity to homes, shops, schools and other buildings in the UK.
Natural gas
Natural gas is a fossil fuel. It is a gas that comes from sea creatures that died millions of years ago and it is non-renewable.We can burn gas to heat our homes and cook our food. Power stations can burn gas to make electricity.
Non-renewable
Non-renewable energy sources are not replaced as we use them. This means they will eventually run out. Fossil fuels such as oil, coal and gas are non-renewable. So is the uranium used in nuclear power stations.
Nuclear bomb
There are two types of nuclear bombs. They both do their damage by releasing massive amounts of energy. In a fission bomb energy is released as large atoms split in two. In a fusion bomb energy is released as pairs of small atoms stick together.
Nuclear fuel
Uranium is a nuclear fuel. It is a radioactive metal found in rocks. Uranium is used as fuel in nuclear power stations. Unlike most fuels, uranium doesn't burn. Instead, energy is released when uranium atoms undergo fission. The waste from this fuel is dangerous and hard to get rid of.
Nuclear power
Nuclear power is a way of making electricity from the energy released by splitting really big atoms such as uranium. This is called fission. The uranium used in nuclear power is a non-renewable energy source.
