Wind Farms Row Blows Up over Cluster Plans; ENERGY: Turbines Face Fight
Wind turbines are used to ___. A. store wind energy B. generate electricity from wind energy C. control the wind speed D. measure the wind direction 相关知识点: 试题来源: 解析 B。解析:本题考查风力涡轮机的用途。选项A,风力涡轮机不是用于储存风能的。选项B,风力涡轮机用于从风能中发电,风能...
解析 A。“Another area where technology is making a big impact is in renewable energy. Solar panels and wind turbines are becoming more common...”风力涡轮机是可再生能源的一种,renewable 符合。fossil 化石能源、nuclear 核能、solar 太阳能都不准确。
The words “clean energy” bring to mind images of wind turbines and solar panels. Think further, and the words “hydrogen”, “geothermal”, “hydropower” and possibly “nuclear” come to mind. This is because much of the...
解析 A。解析:这里考查与风能利用相关的词汇用法。“wind turbines”是风力涡轮机。“convert...into...”是把...转化为...的意思,风力涡轮机是用来把风能转化为电能的。“conserve”表示保存、保护;“consume”表示消耗;“contact”表示联系,均不符合题意。
Wind turbines are used to collect wind energy. They are very helpful in ___. A. increasing sea level B. reducing greenhouse gas emissions C. making deserts larger D. decreasing the number of birds 相关知识点: 试题来源: 解析 B。解析:风力涡轮机用于收集风能,它们在减少温室气体排放方面非常有...
百度试题 结果1 题目Wind turbines generate electricity from ___. A. solar energy B. wind power C. hydro power D. nuclear E. nergy 相关知识点: 试题来源: 解析 B。风力涡轮机从“wind power”风能中发电。
Wind turbines generate ___. A. electricity B. heat energy C. mechanical energy D. chemical E. nergy 相关知识点: 试题来源: 解析 A。风力涡轮机产生电能。heat energy 是热能;mechanical energy 是机械能,但风力涡轮机最终产生的是电能而不是单纯的机械能;chemical energy 是化学能。本题语法点:“genera...
One of the most important resources of renewable energy production is wind source. The main problems with the energy from wind turbines are the low energy density, output power severe oscillations and uncertainty in the obtained energy from them. In order to energize all the loads, the producers...
