09年5月30日雅思作文思路及语料库

Many countries use fossil fuels (coal, oil, natural gas) as the main source of energy. However, in some countries the use of the alternative sources of energy (wind energy and solar energy) are encouraged.

To what extent do you agree or disagree with this development? 在一些国家化石燃料是能源的主要来源，而其他国家却鼓励风能和太阳能，你在多大程度上支持或是反对。（能源类）

★背景知识：

化石燃料的含义：亦称矿石燃料，是一种碳氢化合物或其衍生物。化石燃料所包含的天然资源有煤炭、石油和天然气。

化石燃料的优点：

① 已经大量使用，化石燃料的运用能使大规模工业发展和替代水车, 并且代替木材或泥煤燃烧加热。

化石燃料的缺点：

① 不环保：不断地燃烧化石燃料是排放温室气体二氧化碳的来源之一，是加快全球变暖的因素之一。

② 可持续性差：传统燃料处于被耗尽的边缘，导致能源危机。

太阳能的优点：

① 普遍：太阳光普照大地，没有地域的限制无论陆地或海洋，无论高山或岛屿，都处处皆有，可直接开发和利用，且勿须开采和运输。

② 环保：开发利用太阳能不会污染环境，它是最清洁的能源之一，在环境污染越来越严重的今天，这一点是极其宝贵的。

③ 持久：根据目前太阳产生的核能速率估算，氢的贮量足够维持上百亿年，而地球的寿命也约为几十亿年，从这个意义上讲，可以说太阳的能量是用之不竭的。

太阳能的缺点：

① 效率低和成本高：太阳能利用的进一步发展，主要受到经济性的制约。目前太阳能利用的发展水平，有些方面在理论上是可行的，技术上也是成熟的。但有的太阳能利用装置，因为效率偏低，成本较高，总的来说，经济性还不能与常规能源相竞争

风能利用的优点:

① 以风能作动力，就是利用风来直接带动各种机械装置，如带动水泵提水等这种风力发动机的优点是：投资少、工效高、经济耐用。目前，世界上约有一白多万台风力提水机在运转。澳大利亚的许多牧场，都设有这种风力提水机。在很多风力资源丰富的国家，科学家们还利用风力发动机铡草、磨面和加工饲料等。

② 利用风力发电，以丹麦应用最早，而且使用较普遍。丹麦虽只有500多万人口，却是世界风能发电大国和发电风轮生产大国，世界10大风轮生产厂家有5家在丹麦，世界60%以上的风轮*厂都在使用丹麦的技术，是名副其实的“风车大国”。

风能利用的弊端:

① 风速不稳定,产生的能量大小不稳定

② 风能利用受地理位置限制严重

③ 风能是新型能源,相应的使用设备也不是很成熟
