During the last decade, our fragile dependence on imported oil has brought a new focus on planning for a more secure energy future. At the same time rapid addition of pollutants and greenhouse gases to the atmosphere over the past century has raised fears that the burning of fossil fuels will lead to a drastic rise in global temperature. These concerns have led to renewed interest in energy gases, particularly natural gas, the cleanest burning and least polluting of all fossil fuels.
Gases have unique properties. They are light. They flow easily. Under pressure they compress and take up less space but expand instantly when released. When cooled, they contract, and when heated, they expand. And some of them burn. These are the ones we call energy gases.
