Wind Power

saving energy wind turbines

WIND POWER or wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping. Wind power has a significant role in saving energy worldwide, as it is truly a sustainable and renewable energy, has a much smaller impact on the environment compared to burning fossil fuels, and has for many centuries been one of the most common and accepted ways of harnessing and saving energy.

Wind farms, an increasingly common sight across the landscape, consist of many individual wind turbines, which are connected to the electric power transmission network. Wind is an inexpensive source of electric power, competitive with or sometimes cheaper than coal or gas, and can feed some energy into the grid or provide electric power to isolated off-grid locations.

Wind is of course, by nature, an intermittent energy source, which cannot make electricity nor be dispatched on demand and it also gives variable power, which is consistent from year to year but varies greatly over shorter time scales. Therefore, it must be used together with other electric power sources or storage to give a reliable supply. Power-management techniques such as having dispatchable power sources, enough hydroelectric power, excess capacity, geographically distributed turbines, exporting and importing power to neighbouring areas, energy storage, or reducing demand when wind production is low, can in many cases overcome consistency problems and accurate weather forecasting helps the electric-power network to be prepared for the predictable variations in production that occur.

In terms of its place in the overall landscape of sustainable power sources and saving energy, wind power supplied approximately 15% of the electricity consumed in Europe in 2019 and well over 80 countries are using wind power to supply their electric power grids. Because wind is a clean source of renewable energy that produces no air or water pollution making operational costs nearly zero once a turbine or other suitable machine is erected. Mass production and technology advances are increasingly making turbines cheaper, and many governments offer incentives and tax offers to increase wind energy development.
