Offering savings and a variety of uses, natural gas is one of the most popular forms of energy used in homes. Chosen is more than 10 million households in France, natural gas is an energy that offers multiple benefits in terms of heating.
Less dense than air and largely composed of methane, natural gas comes from a mixture of hydrocarbons, which are naturally present in some types of rocks. Once treated, it has no colour or odour.
It is the third most commonly used energy source in the world, after oil and coal. Gas resources are relatively large, estimated to last another hundred years at current rates of use.
Less rich in carbon than coal or oil, natural gas is the cleanest fossil fuel.
