随堂训练 1 (2015·嘉兴二模) While other countries debate whether to fix wind turbines(涡轮机)offshore or in distant areas, Denmark is building them right in its capital. Three windmills(风车)were recently introduced in a Copenhagen neighbourhood, and the city plans to add another 97. “We’ve made a very ambitious commitment to make Copenhagen CO2-neutral by 2025, ”Frank Jensen, the mayor, says. “But going green isn’t only a good thing. It’s a must. ”The city’s carbon-neutral plan, passed two years ago, will make Copenhagen the world’s first zero-carbon capital. With wind power making up 33% of Denmark’s energy supply, the country already features plenty of wind turbines. Indeed, among the first sights greeting airborne visitors during the landing at Copenhagen’s Kastrup airport is a chain of sea-based wind towers. By 2020, the windswept country plans to get 50% of its energy from wind power. Now turbines are moving into the city and these ones will cost less than half the price of those sea-based. Having the energy production closer makes it cheaper, and land-based turbines are the cheapest possible source of energy available today. Fixing them also makes the locals more aware of their energy consumption. Though considerably less attractive than it was in ancient times, the windmill is enjoying popularity in the 21st century. “Windmills are a symbol of the new and clean Copenhagen, ”says resident Susanne Sayers. Meanwhile, fellow Copenhagen citizen Maria Andersen worries about the noise, explaining that she wouldn’t want a wind turbine in her neighbourhood. While Copenhagen citizens approve of the windmills, they’re less willing to live close to one. The answer, the city has decided, is to sell turbine shares. |
