Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water.But it also leads to a fossil fuel.Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years.Burning it releases fewer pollutants than oil or coal.The gas is mainly methane (甲烷).It produces half the carbon dioxide of other fossil fuels.So it may help cut the production of carbon gases linked to climate change. Russia is first in what are called "proved reserves" of natural gas.The United States is sixth.Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America.They drilled straight down into formations where gas collects.As these supplies were used up, big drillers looked for similar formations in other countries. But now the industry is taking a new look.Companies are developing gas supplies trapped in shale (页岩) rock two to three thousand meters underground.They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock.This causes the rock to fracture, releasing the gas.Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states.Gas shale exploration is being done mainly by small to medium sized companies.Eric Potter, a program director, says more than half the gas in the United States is now coming from these new reserves. But hydraulic (液压的) fracturing can also produce debate and anger over the risk of groundwater pollution.This method of drilling is not federally supervised under the Safe Drinking Water Act.Some in Congress want to end that exemption (豁免) from the law.

Once you’ve found the right taxi, problems of fares, meters and other charges come into play. In some countries, all taxis are1, and the government regulates fares so you can expect 2problems.
