The sun heats the Earth’s surface unevenly causing differences in air pressure. It’s these differences that cause wind to flow over our planet’s surface. Scientists convert wind energy into electrical energy by using wind mills or wind turbines. The turbines take the movement of the air and convert it into mechanical energy. Each wind mill contains blades that are connected to a generator. The faster the blades spin the more energy that is produced by the generator. In areas that have constant winds, you will find wind farms and small, wind-driven generators. On these wind farms are hundreds of wind turbines capable of providing the electricity for entire communities. The small wind-driven generators are used for individual homes to produce electricity. Similar to solar energy, wind energy cannot be consistently used. There are areas around the world that do not have constant winds. In areas like windy mountain passes, the wind does not blow continuously. Therefore wind energy is only dependable for certain areas of the planet.
选项
答案
太阳使地球表面受热不均而造成气压的差异,正是这些不同的气压引起我们这个星球表面风的流动。科学家利用风车或风力涡轮机将风能转化成电能。涡轮机吸取流动的空气,并将其转化成机械能。每个风车都装有与发电机相连接的叶片。叶片旋转得越快,发电机产生的能量就越多。在有恒定风的地方,你会发现风力发电场和小型的风力发电机。在这些风力发电场上有数百个风力涡轮机,能够为整个社区提供电力。那些小型的风力发电机所产生的电力供个人家庭使用。与太阳能相似的是,风能不能持续使用。世界上有些地区没有恒定风。在有些地方,诸如风力很强的山口,风时断时续。因此,只有地球上的某些区域才有可靠的风能。
