Wind turbines work by converting the kinetic energy in wind into electricity. This makes them a great renewable energy source for generating electricity. However, their output can also be highly variable and reliant on the intermittency of wind.<\/p>\n\n\n\n

Increases in wind turbine efficiency, generation capacity and technology are improving their feasibility. This is particularly true with new designs for varied landscapes and wind speeds. These advancements are already increasing wind energy adoption rates, with wind power playing a significant role in future renewable energy plans.<\/p>\n\n\n\n

The Current State of Wind Energy<\/strong><\/h2>\n\n\n\n

The last decade saw a significant decrease in the price of wind energy, with an average decline of 44%-78%<\/a>.<\/p>\n\n\n\n

Onshore wind farms can now create electricity at an average cost of USD 0.051 to 0.099 per kilowatt-hour (kWh), with offshore wind farms delivering it at around USD 0.115 per kWh. Considering the decreasing prices, the ease of installation and the low maintenance costs, wind turbines are becoming a go-to energy source in many regions.<\/p>\n\n\n\n

Wind energy capacity has increased by a factor of almost 75<\/a> since the late 1990s, and experts predict a 9% annual growth rate<\/a> until at least 2030.<\/p>\n\n\n\n

What Is a Wind Turbine?<\/strong><\/h2>\n\n\n\n

A wind turbine is a relatively simple device that turns wind energy into electrical energy. It is an excellent source of cheap, green electricity that is favoured around the world for its high electricity generation potential and low land use. <\/p>\n\n\n\n

Versatile and scalable, wind turbines can be deployed in onshore and offshore formations, as well as in low-rise residential areas, high-rise urban areas and along highway medians.<\/p>\n\n\n\n

How Do Wind Turbines Work Step by Step?<\/strong><\/h2>\n\n\n\n

In their basic form, wind turbines are very simple. A wind turbine consists of<\/a> a rotor with spinning blades, a power generator and a pillar.<\/p>\n\n\n\n

Wind makes the blades spin, transferring energy to the power generator. The power generator consists of gears that rotate, turning the energy into electricity. The turbine typically connects to a small network of multiple turbines, which then connect to a larger energy grid.<\/p>\n\n\n\n

Wind Turbine Function & Design<\/strong><\/h3>\n\n\n\n

Wind turbine blades are designed for efficiency at a variety of wind speeds. As a result, the ideal wind speed<\/a> for a utility-scale turbine is typically around 48 km\/h, with a minimum functional wind speed of approximately 12.8 km\/h and a maximum wind speed of approximately 88 km\/h. This is achieved through a combination of aerodynamic blade design<\/a> and efficient energy transfer.<\/p>\n\n\n\n

The blades are flat on one side and curved on the other, similar to the wings of a plane. Generally, the curved side increases speed as the wind blows over them, generating a pressure difference. As the pressure difference increases, the blades start moving to compensate for the pressure difference, effectively creating a new zone of low pressure. The continuous nature of the phenomenon means that the blades keep turning for as long as there is wind.<\/p>\n\n\n\n

Wind Turbine Types<\/strong><\/h3>\n\n\n\n

There are several types of wind turbines for different applications, wind speeds and installation types. Together they form an assortment of products that range from small residential wind turbines to large-scale wind farm with turbines towering as high as 280 meters<\/a>. As a result, each type of wind turbine design works efficiently in different situations.<\/p>\n\n\n\n
