Quesaonsare based on thefollowingpassage
Energy independence．It has a nice ring to it，doesn’t it?If you think so，you’re not alone，because energy independence has been the dream of American presidents for decades，and never more so than in the past few years，when the most recent oil price shock has been partly responsible for kicking off the great recession．
“Energy independence”and its rhetorical(修辞的)companion“energy security”are，however’slippery concepts that are rarely thought through．What is it we want independence from，exactly?
Most people would probably say that they want to be independent from imported oil．But there are,reasons that we buy all that oil from elsewhere．
The first reason is that we need it to keep our economy nmning．Yes，there is a trickle(涓涓细流)of biofuel(生物燃料)availaB．e，and more may become available，but most biofuels cause economic waste and environmental destruction．
Second．Americans have basically decided that they don’t really want to produce all their own oil．They value the environmental quality they preserve over their oil imports from abroad．Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection．To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?
Third，there are benefits to trade．It sllows for economic efficiency,and when we buy things from places that have lower production costs than we do，we benefit．And although you don’t read about this much，the United States is also a large exporter of oil products，selling about 2 million barrels ofpetroleum products per day to about 90 countries．
There is no question that the United States imports a great deal of energy．and，in fact，relies on that steady flow to maintain its economy．When that flow is interrupted，we feelthe pain in short supplies and higher prices．At the same time，we derive massive economic benefits when we buy the most afrordable energy on the world market and when we engage in energy trade around the world．
