【正确答案】 An Oasis in the City
Walking down the buzzing streets of a big city, with a wall of skyscrapers towering over you, their all-glass facades seem to shimmer under the sun. These mammoth structures, which were once a symbol of progress and prosperity, is no longer—at least in the eyes of environmentally conscious people. The buildings' glazed windows absorb a tremendous amount of energy, and tend to significantly raise the mercury of the interiors. That translates into a fat electricity bill. With growing concern about energy conservation the world over, more and more architects have tried to incorporate environmentalism into their designs.
The use of solar panels, which collect the sun' s energy to power lights and other electrical appliances , has been widely touted as the next big thing in green buildings. As the debate over the potential exhaustion of fossil fuels rages on, wind and thermal power are also considered good alternatives.
