Since the early 2000s, wind turbines have grown in size—in both height and blade lengths—to generate more energy per unit. Today, the tallest turbines can reach over 200 meters (650 ft) in height and cost more than $12 million to manufacture and install. The above infographic uses data compiled from company portfolios to showcase the biggest wind turbines currently being developed and to put these huge structures into perspective.
Blade Runners
The biggest turbines are all located over water. The so-called offshore turbines can be taller than those onshore, which means they can harness more wind energy and produce more electricity. MingYang Smart Energy, a Chinese wind turbine manufacturer, is in the process of building the biggest wind turbine so far. Their new MySE 16.0-242 model is still under construction and is expected to be online by 2026. It will be 264 meters tall, with a blade length 118 meters long and rotor diameter of 242 meters. It features a nameplate capacity of 16 megawatts that can power 20,000 homes per unit over a 25-year service life. The first commercial turbine will be installed at the MingYang Yangjiang Qingzhou Four offshore wind farm, which is in the South China Sea. Here are four of the biggest wind turbine models on the market right now, the companies that are making them, and where the prototypes are being installed: These huge structures can be two times taller than a typical turbine currently in operation, generating almost four times more energy. Prototypes for two of the top four turbine models—the SG 14-236 DD and V236-15.0— are scheduled to be installed in 2022 in Denmark, a country that was a pioneer in developing commercial wind power during the 1970s, and is home to the world’s largest wind-turbine manufacturer, Vestas. From our list, General Electric’s Haliade-X is the only turbine currently online; the prototype has been operating since October 2021 in the Netherlands.
Wind Energy’s Rapid Global Growth
Wind generated 6.6% of the world’s electricity in 2021, up from 3.5% in 2015, when the Paris Agreement was signed, making it the fastest-growing source of electricity after solar. A number of countries have achieved relatively high levels of wind energy penetration in their electricity grids. Wind’s share of electricity generation was nearly 50% in Denmark and sits above 25% in countries such as Ireland, Uruguay, and Portugal. In the United States, wind supplied 8.4% of total electricity generation.

The global wind turbine market size was valued at $53.4 billion in 2020 and is projected to reach $98.4 billion by 2030, growing at a CAGR of 6.3%. As one of the fastest-growing segments of the energy sector, wind energy generation will continue to grow as wind turbines also scale up in size. on
#1: High Reliability
Nuclear power plants run 24/7 and are the most reliable source of sustainable energy. Nuclear electricity generation remains steady around the clock throughout the day, week, and year. Meanwhile, daily solar generation peaks in the afternoon when electricity demand is usually lower, and wind generation depends on wind speeds.As the use of variable solar and wind power increases globally, nuclear offers a stable and reliable backbone for a clean electricity grid.
#2: Clean Electricity
Nuclear reactors use fission to generate electricity without any greenhouse gas (GHG) emissions.Consequently, nuclear power is the cleanest energy source on a lifecycle basis, measured in CO2-equivalent emissions per gigawatt-hour (GWh) of electricity produced by a power plant over its lifetime. The lifecycle emissions from a typical nuclear power plant are 273 times lower than coal and 163 times lower than natural gas. Furthermore, nuclear is relatively less resource-intensive, allowing for lower supply chain emissions than wind and solar plants.
#3: Stable Affordability
Although nuclear plants can be expensive to build, they are cost-competitive in the long run. Most nuclear plants have an initial lifetime of around 40 years, after which they can continue operating with approved lifetime extensions. Nuclear plants with lifetime extensions are the cheapest sources of electricity in the United States, and 88 of the country’s 92 reactors have received approvals for 20-year extensions. Additionally, according to the World Nuclear Association, nuclear plants are relatively less susceptible to fuel price volatility than natural gas plants, allowing for stable costs of electricity generation.
#4: Energy Efficiency
Nuclear’s high energy return on investment (EROI) exemplifies its exceptional efficiency. EROI measures how many units of energy are returned for every unit invested in building and running a power plant, over its lifetime. According to a 2018 study by Weissbach et al., nuclear’s EROI is 75 units, making it the most efficient energy source by some distance, with hydropower ranking second at 35 units.
#5: Sustainable Innovation
New, advanced reactor designs are bypassing many of the difficulties faced by traditional nuclear plants, making nuclear power more accessible.
Small Modular Reactors (SMRs) are much smaller than conventional reactors and are modular—meaning that their components can be transported and assembled in different locations. Microreactors are smaller than SMRs and are designed to provide electricity in remote and small market areas. They can also serve as backup power sources during emergencies.
These reactor designs offer several advantages, including lower initial capital costs, portability, and increased scalability.
A Nuclear-Powered Future
Nuclear power is making a remarkable comeback as countries work to achieve climate goals and ultimately, a state of energy utopia. Besides the 423 reactors in operation worldwide, another 56 reactors are under construction, and at least 69 more are planned for construction. Some nations, like Japan, have also reversed their attitudes toward nuclear power, embracing it as a clean and reliable energy source for the future.
