Expanding Offshore Wind Plants
Global decarbonization efforts require offshore wind plant expansions. The U.S. alone plans to expand energy production by 30 gigawatts (GW), which is enough emission-free electricity to power 90 million houses. Countries are developing funding that’s specific to renewable energy development projects to improve production rates further.
Offshore wind projects increased significantly from 2010 to 2019. Initially, wind plants generated 190 megawatts (MW) of electricity globally. As their sizes grew, they began producing 400 MW on average.
Since wind plants expanded, the cost of clean energy dropped by nearly 40% on average. As plant sizes continue growing, researchers predict constant decreases in the Levelized Cost of Energy (LCOE) before reaching a plateau. Energy scientists evaluate the influence of turbine advancements in the future and their impacts on the LCOE.

The Decreasing Wind Turbine Cost
In recent years, turbine manufacturers installed longer blades, helping wind plants capture more energy. Generators reached their optimal sizes for efficiency, creating more power when paired with bigger blades. The component upgrades are cost-effective, helping consumers access more emission-free electricity for less.
While some energy professionals expect windpower’s LCOE to decrease with further advancements, others identify limitations. After evaluating wind shear and transportation challenges, individuals determined that manufacturers have already reached optimal turbine sizes. They predict adding taller shafts or different features will decrease general efficiency and increase energy costs.
Other turbine scientists evaluate the potential benefits of increasing turbine sizes for onshore wind production. They expect tower heights to reach 115 meters by 2030 and feature larger rotor diameters. Professionals expect that structural advancements will reduce power costs and improve production rates.
