Final answer:
Wind is a renewable resource because it is naturally replenished and can't be depleted by human use. It is harnessed to generate electricity without depleting its source, unlike nonrenewable resources such as fossil fuels.
Step-by-step explanation:
Wind is considered a renewable resource because it replenishes naturally and cannot be used up over human time scales. Wind energy is harnessed through wind turbines which generate electricity by converting the kinetic energy of wind into mechanical power. This form of energy is part of a sustainable approach, where resources are used in a manner that meets current needs without compromising the ability of future generations to meet theirs. Unlike nonrenewable resources, such as fossil fuels like coal, oil, and natural gas, which exist in finite quantities and are depleted by consumption, wind does not run out and is continually produced by natural processes.
Sustainable use of wind energy implies that wind power, among other living things considered renewable, must be harnessed without overuse to maintain its status as a renewable resource. In contrast, when a resource like fossil fuel is used at a rate that is slower than its natural replenishment, it can theoretically be considered renewable, but due to the current consumption rates, fossil fuels are classified as nonrenewable.
Wind energy farms and wind power are examples of how alternative energy sources are being utilized to shift away from fossil fuels, which are not only limited but also contribute to global warming through carbon dioxide emissions produced during combustion.
