The following outline is provided as an overview of and topical guide to wind energy: Wind energy – the kinetic energy of air in motion, also called wind. == What type of thing is wind energy? == Wind energy can be described as all of the following: * Energy – an indirectly observed quantity, often understood as the ability a physical system has to do work on other physical systems. * * Renewable energy – energy which comes from natural resources which are naturally replenished. * Natural resource – materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy. * * Renewable resource – natural resource with the ability to reproduce through biological or natural processes and are replenished with the passage of time. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Outline of wind energy」の詳細全文を読む スポンサード リンク
