     As demand for power and fuel grows steadily in the coming decades, we must consider every possible

energy source (来源) at hand if we're to meet the world's needs. And because clean natural gas is found in

great plenty, there is little doubt that it will play a major role on the world energy stage in this century, much

like oil did in the last. But, like oil, gas reserves are concentrated in just a few places in the world, usually

far from where they're needed most. And that's only part of the challenge. The world has had well over 100

years to search for oil and to build the necessary facilities (设施) to bring it to market; the natural gas facilities,

particularly when it comes to liquefied (液化) natural gas (LNG), is not nearly as developed.

     So what needs to be done? On the supply side, producing nations need policies that allow for better

development of their natural gas in an open, stable business environment, not one in which the rules of

the game change without warning. The governments of consuming nations, on the other hand, must make

policies for sustainable (可持续的) development to ensure they'll have enough supplies in the future. That

means building the related facilities, including LNG stations. This, in turn, will require coastal areas to allow

these necessary, but not necessarily pretty, facilities to be built in their backyards. And energy companies

have a responsibility to be good neighbors in those areas by operating these facilities responsibly and safely.

They must also continue to put in the billions of dollars needed to build the complex transport and storage

facilities required to bring more gas to market.

     Expanding and diversifying (使多样化) energy sources by using more natural gas could lead to lower

fuel prices and to greater energy security. We've taken some of the steps to get started, but we need your

help to get the rest of the way.
