A concept rendering of offshore vertical axis wind turbines (VAWTs). What makes renewable energy so exciting is the immense economic potential of groundbreaking technology advancements. A recent ...

EPFL researchers developed optimal pitch profiles for vertical-axis wind turbines using a genetic learning algorithm. The new pitch profiles resulted in a 200% increase in turbine efficiency and a 77% ...

The world's first offshore wind farm was installed in 1991 off the coast of Vindeby on the Danish island of Lolland. It included 11 turbines with a capacity of 450 kW each, and the project cost 10 ...

These scale model wind turbines use fixed-pitch blades to evaluate a new vertical axis wind turbine design. Vertical axis wind turbines are easier to install than traditional horizontal axis wind ...

Compact (H-type) vertical-axis wind turbines (VAWTs) are not as familiar as their horizontal-axis, propeller-type cousins. The two have their origins in the windmills of the 12th century, and even ...

The type of wind turbine you’re used to seeing in stock photos of wind farms is called a horizontal axis wind turbine (or, HAWT). But there is another form of wind power, called a vertical axis wind ...

A vertical wind turbine has been successfully installed at a community centre in Yagapudayanpatti, near Trichy, providing ...

Instead of a hulking rotor, New World Wind plants “trees” covered in tiny leaf-shaped micro-turbines. Each Aeroleaf is a vertical-axis unit designed to sip energy from turbulent, low, urban winds ...

13 February 2003 – A team of wind power experts are hoping that heightened interest in the renewable energy market will enable them to re-launch Eurowind Developments Limited, a company which promotes ...

In recent years, vertical wind turbines have begun to gain traction outside of industrial projects. What once seemed unfeasible for residential use due to noise, cost, and complicated maintenance has ...

Trichy: A vertical axis wind turbine which can generate 0.5 kw of electricity has been installed at a community centre in a ...

Wind Engineering, Vol. 41, No. 1 (February 2017), pp. 74-90 (17 pages) Abstract The performance of a 5-m diameter Darrieus vertical axis wind turbine was predicted using both a double multiple ...
