Colourless, Odourless, lighter than air. Natural gas may not have much impact on the senses, but as a source of heat and power it is transforming energy markets. An unexpected boom in shale gas that has taken off in America may well spread elsewhere and will add massively to global gas supplies. Shale gas--an "unconventional" source of methane, like coal-bed gas (in coal seams) and tight gas (trapped in rock formations)--has rapidly transformed America's energy outlook. At the same time discoveries of vast reserves of conventional gas from traditional wells have pushed up known reserves around the world. Gas is the only fossil fuel set to increase its share of energy demand in the years to come. The trouble with gas is that it is difficult and expensive to transport. That used to be true of oil too, but since the development of supertankers in the 1960s it can be shifted relatively cheaply to find a customer in the world market. Gas needs a ready buyer and a way of delivering it. Because of those hefty transport costs, gas does not behave like a commodity. Only one-third of all gas is traded across borders, compared with two-thirds of oil.
