Small wind turbines that can power a single home may have an electricity generating capacity of 10 kilowatts kW. The largest wind turbines in operation have electricity generating capacities of up to kilowatts 10 megawatts , and larger turbines are in development. Large turbines are often grouped together to create wind power plants, or wind farms , that provide power to electricity grids. Horizontal-axis turbines have blades like airplane propellers, and they commonly have three blades.
The largest horizontal-axis turbines are as tall as story buildings and have blades more than feet long. Taller turbines with longer blades generate more electricity. Nearly all of the wind turbines currently in use are horizontal-axis turbines. Vertical-axis turbines have blades that are attached to the top and the bottom of a vertical rotor. The most common type of vertical-axis turbine—the Darrieus wind turbine, named after the French engineer Georges Darrieus who patented the design in —looks like a giant, two-bladed egg beater.
Some versions of the vertical-axis turbine are feet tall and 50 feet wide. Very few vertical-axis wind turbines are in use today because they do not perform as well as horizontal-axis turbines.
Wind farms are clusters of wind turbines that produce large amounts of electricity. A wind farm usually has many turbines scattered over a large area. One of the United States' largest wind farms is the Horse Hollow Wind Energy Center in Texas, which at the end of , had wind turbines spread over about 47, acres. The project has a combined electricity generating capacity of about megawatts or , kilowatts.

Difference between Windmill and Wind Turbine Terminology of Windmill and Wind Turbine The terms windmill primarily refers to a wind-powered machine that converts the energy of wind to pump water or grind or mill grains such as wheat or corn and turn them into flour for bread making.
Working of Windmill and Wind Turbine Wind turbines work on a simple principle. Operating Principle of Windmill and Wind Turbine The blades of a wind turbine operate on the principle of lift and drag. Applications of Windmill and Wind Turbine Windmills convert the energy of wind into rotational energy which is mainly used for water pumping.
Windmill vs. Wind Turbine Wind energy plays a significant role in the energy supply of the developed world and is a renewable source of energy.

A windmill is most useful for processes you may see on farms or in the country. These include pumping water, milling crops, sawing wood, grinding grain and more. Though some windmills can work to generate electricity, they are predominately helpful for traditional farm-related activities.
A wind turbine creates electricity mostly for commercial use in homes, businesses, schools, local government buildings and more. There are three types of wind turbines, too. The first is a utility-scale turbine that generates electricity and drives it to the power grid for electric utilities or systems.
The second is distributed, meaning a single wind turbine powers a home or small business that does not connect to the grid.
The last is offshore wind energy, which entails multiple wind turbines in a large body of water. Together, the turbines generate a greater amount of power. This is the concept of a wind farm, where multiple turbines work congruently for a larger electricity output. Apart from their terminology and end production goals, their applications and purposes are what set them apart. Though both are sustainable, turbines are leading the wind energy movement due to their versatility and ability to produce large amounts of electricity.
Fossil fuels and non-renewable energy are on their way out, however slowly. The progress is gradual but sustainable, and renewable energy is working its way into the industry. Wind power is one of the central focuses of this change.
One of the oldest arguments in support of fossil fuels is that renewable energies are impractical and expensive. But wind energy is challenging, and disproving, those ideas. First, renewable energy prices are dropping every year. While fossil fuel prices fluctuate depending on the economy and geopolitics, wind prices remain consistent.
But the debate between renewable and non-renewable energy continues. Skeptics raise concerns over the placement of the turbines and their abilities for power.
Those who are pro-wind energy discuss how the pros outweigh the cons. Those in favor also bring up the environmental benefits of renewable energy. Fossil fuels release CO2 emissions, which contribute to the greenhouse gas effect and climate change. Wind energy has no harmful emissions and can last theoretically forever. Wind is essentially disrupting the norms of the energy industry.
It is focusing the conversation on better ways to generate electricity for people and the earth. Renewable energy is here for the long run. As more people turn to sustainable options, renewable energy resources will continue to develop. And technology plays a helpful role in that development. For instance, you may know of the Internet of Things IoT and how it is the center of the new technological movement.
IoT is a network of interconnected devices that can send and receive data through internet connections. It is where much of the technology of today emerges from. With wind energy, you may see IoT providing technology and devices to improve upon an already clean system. A platform, for example, that links wind turbines together digitally could optimize their storage. This could ultimately maximize their capacity for storing electricity.
Another point of skepticism towards wind power is its ability to store energy, so future technology will come in handy for maximizing it. Though it can already save energy for periods of time without wind, new tech will help improve upon its capacity. Bladeless wind turbines have been in talks for years and are starting to come to fruition.
