Loftvélar

Loftvélar, the Icelandic term for wind turbines, are devices that convert kinetic energy from wind into electrical energy. They consist of blades mounted on a tower, a gearbox, and a generator that produces electricity. The blades capture wind energy, causing the rotor to spin. The gearbox increases the rotational speed before the generator transforms mechanical energy into electrical power, which is then fed into the national grid.

The development of loftvélar began in the early 20th century, but significant growth occurred in the late 1990s with the advent of modern aerodynamic blade designs and advanced materials. Iceland, with its abundant wind resources and sparse population, has become a leading adopter of wind technology. Approximately 20% of Iceland’s electricity comes from wind, largely generated by a network of turbines located along coastal regions and within the highlands.

In recent years, Icelandic companies have participated in international wind projects and have helped supply technology and expertise to other countries. The country’s commitment to renewable energy is reflected in its policy environment, which encourages investment through subsidies and streamlined permitting processes.

Global trends show increasing deployment of large‑scale offshore wind farms, and Iceland is poised to contribute to knowledge transfer in floating wind turbine technology. Loftvélar play an essential role in reducing dependence on fossil fuels, mitigating greenhouse gas emissions, and supporting sustainable development goals worldwide.
