Question

[nguyễn thị vi tính]

In Britain, natural gas is the most popular fuel for heating homes, and for cooking. It is piped all over the country from the gas fields below the North sea. Natural gas is used chiefly as a direct source of energy, although it is also used in the chemical industry. At the moment, the supply is plentiful, but it will be running short by the end of the century, and it will run out during the 21^st century unless new supplies are found. We could do without natural gas, as coal gas can be used as a substitute, and there should be enough coal to last for several centuries. However, it is a form of energy which is not only cheap, but also highly efficient.
