Not Energy Efficient Refrigerators
Each year millions of Americans with old, inefficient refrigerators in their kitchens buy new, energy saving ones. That may sound like an efficiency boon, but what’s vexing efficiency advocates is that an increasing number of consumers don’t actually get rid of the old fridge. Instead, they move it to another area of the house and keep using it— increasing their energy usage over all.
America’s secondary-fridge trend is highlighted in "Energy Vision 2010:Towards a More Energy Efficient World", a new report by the World Economic Forum and HIS Cambridge Energy Research Associates. The report notes that while the average refrigerator in the United States uses three-quarters less energy than in 1975, despite being 20 percent larger, "the number of U. S. households with two or more refrigerators has increased, and the secondary refrigerators are typically older and less efficient than the primary models". Every year about 10 percent of households that purchase new refriger- ators keep their old units,a practice that is adding as many as one million secondary units to homes annually.
Jennifer Thome Amann, buildings program director at the American Council for an Energy-Efficient Economy, explained that secondary units are often kept for convenience in larger homes and that owners aren’t always aware of how much a "beer and deer" fridge as they’re called in parts of the country where hunting is popular, can cost them. " You’re not saving any money on efficiency if you’re keeping that old one plugged in," she said.
Unplugging the 29. 6 million secondary units nationwide that are candidates for retirement would save 25 million megawatt hours of electricity,or about $ 2.8 billion,the energy department study noted. Individual owners could save from $ 420 to $ 750 in energy costs over the lifetime of an older unit by retiring it, depending on the age of the unit. Some utilities and state agencies have launched programs that offer financial incentives and free pick-up services to entice customers to give up secondary fridges. And some will not issue rebates to purchasers of new energy efficient refrigerators unless they provide proof that their old one was recycled.
"This doesn’t mean the efficiency efforts have been in vain or were not worth undertaking," she added, "it means that we should continue improving efficiency and undertake a series of parallel efforts to recycle old units, discourage upsizing and measure the right things if we want to turn absolute consumption downward."
What can we learn from the report mentioned in the second paragraph?
选项
A、The average refrigerator in America uses only 3/4 energy, comparing with that in 1975.
B、The size of the average refrigerator in America is 20% larger than that in 1975.
C、The refrigerators in America are less efficient than the primary models.
D、U.S. households usually have two or more refrigerators at home.
答案
B
解析
事实细节题。根据题干提示定位到文章第2段第2句:…the average refrigerator in the United States uses three quarters less energy than in 1975,despite being 20 percent larger...该结构的逻辑主语是the refrigerator,larger之后为避免重复省略了than in 1975。[B]项中的20%larger直接对应文中的短语despite being 20 percent larger,故选[B]项。
