问题     Global energy demand is expected to triple by mid-century. The earth is unlikely to run out of fossil fuels by then, given its vast reserves of coal, but it seems unthinkable that we will continue to use them as we do now. It’s not just a question of supply and price, or even of the disease caused by filthy air. The terrorist assault on the World Trade Center raises other scary scenarios: how much easier would it be to crack open the Trans-Alaska pipeline and how much deadlier would it be to bomb a nuclear plant than to attack a wind farm?
    Skeptics may recall the burst of enthusiasm for conservation and renewable power when oil prices quadrupled in the 1970s. State-funded energy research and development surged, while tax incentives boosted solar, wind and other alternatives to petroleum and the atom. But when oil supplies loosened and prices dropped in the early 1990s, governments lost interest. In the state of California, subsidies evaporated, pushing wind companies into bankruptcy.
    Clean energy has long way to go. Only 2.2% of the world’s energy comes from "new" renewables such as small hydroelectric dams, wind, solar and geothermal. How to boost that share — and at what pace — is debated in industrialized nations — from Japan, which imports 99.7 % of its oil, to Germany, where the nearby Chernobyl accident turned the public against nuclear plants, to the U.S., where the Bush Administration has strong ties to the oil industry. But the momentum toward clean renewables is undeniable. How soon we reach an era of clean, inexhaustible energy depends on technology. Solar and wind energies are intermittent: When the sky is cloudy or the breeze dies down, fossil fuel or nuclear plants must kick into compensate. But scientists are working on better ways to store electricity from renewable sources.
    While developed nations debate how to fuel their power plants, however, some 1.6 billion people — a quarter of the globe’s population — have no access to electricity or gasoline. Many spend their days collecting firewood and cow dung, burning it in primitive stoves that belch smoke into their lungs. To emerge from poverty, they need modern energy. And renewables can help. From village-scale hydropower to household photovoltaic systems to bio-gas stoves that convert dung into fuel.
    Ultimately, the earth can meet its energy needs without fouling the environment. "But it won’t happen," asserts Thomas Johansson, an energy adviser to the United Nations Development Program, "without political will." To begin with, widespread government subsidies for fossil fuels and nuclear energy must be dismantled to level the playing field for renewables. Moreover, government should pressure utility to meet targets for renewable sources of energy.
Which one of the following applies to the use of renewables in developed nations?
选项 A、The more developed a nation is, the higher the proportion of renewables being used.
B、Developed nations are experiencing a fierce energy revolution.
C、Developed nations’ ties with the oil industry are becoming tense.
D、Developed nations haven’t reached a consensus about using more renewables.
答案D
解析 这是一道细节题。文章第三段指出：对于如何提高可再生能源所占的比例以及以什么样的速度来提高，工业化国家一直在争论。这说明，发达国家对于可再生能源的应用没有达成一致意见。D说“对于利用更多的可再生能源，发达国家还没有达成一致意见”，这与文章的意思符合。文中没有提到A和B；文中提到ties with theoil industry时是说“在美国，布什政府与石油工业的联系非常密切”，说明C不对。
