Natural Gas

Natural gas is produced from reservoirs deep beneath the earth's surface.It is a fossil fuel,meaning that it is derived from organic material buried in the earth millions of years ago.The main component of natural gas is methane(甲烷).

The popularity and use of clean natural gas has increased dramatically over the past 50 years as Dipeline infrastructure(基礎(chǔ)設(shè)施)has been installed to deliver it conveniently and economically to millions of residential,commercial and industrial customers worldwide.Today,natural gas service is available in all 50 states,and is the leading energy choice for fueling American homes and indus-tries.More than 65 million American homes use natural gas.In fact,natural gas is the most eco-nomical source for home energy needs,costing one-third as much as electricity. In addition to heat-ing homes,much of the gas used in the United States is used as a raw material to manufacture a wide variety of products,from paint,to fibers for clothing,to plastics for healthcare,computing and fur-nishings. Natural gas is also used in a significant number of new electricity-generating power plants.

Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuels.dioxide(二氧化碳)and water vapor-the same substances emitted when humans ex-hale.Compared with some other fossil fuels,natural gas emits the least amount of carbon dioxide in-to the air when combusted(燃燒)-making natural gas the cleanest burning fossil fuel of all.The industry also is subject to substantial federal regulation in the areas of production and distribution,which help ensure it is provided to consumers safely and cleanly.

The United States consumes about one-third of the world's natural gas output,making it the lar-gest gas consuming region in the world.The U.S.Department of Energy's Energy Information Ad-ministration forecasts that natural gas demand will grow by more than 50 percent by 2025.

There are huge reserves of natural gas beneath the earth's surface.The largest reserves of natu-ral gas can be found in Russia,West and North Africa and the Middle East.LNG(液化天然氣)has been produced domestically and imported in the United States for more than four decades.To-day,the leading importers of LNG are Japan,Korea,F(xiàn)rance and Spain.
