Wind power has always been a trade off between clean energy and the visual, acoustic, and ecological cost of giant spinning blades. A new generation of radical designs promises something different, ...

One problem when you try to field super-big wind turbines: All the components involved get super heavy as well. No surprise, then, that there are efforts afoot to figure out ways of lightening up the ...

What is wind power density? The different types of generators used in wind-turbine systems. What architecture is most commonly used in high-power wind-energy-conversion systems (WECS)? Fundamental ...

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT).

Lower costs, cheaper wind turbines and hurricane safe. That’s the future of offshore wind energy promised by SeaTwirl, a company that makes vertical wind turbines. These new turbines have capabilities ...

With their considerable height and large blades turning almost hypnotically, wind turbines have become an iconic symbol of the planet's shift to renewable sources of energy. In Spain, however, one ...

Scientists have designed a new wind turbine that they say can better recover from turbulent conditions. By adding rotors to turbines, it will help them rebound from what are known as wakes. The new ...

Clever aerodynamic use of slow and steady air currents could set a new milestone for large-scale clean wind-generated electricity. At least, that is the claim of one rooftop renewable energy company, ...

As data-center developers frantically seek to secure power for their operations, one startup is proposing a novel solution: ...

Andrew Forrest's huge wind plans to power his Pilbara mining operations have undergone a "substantial redesign," proposing to halve its footprint, while shooting for the same 2.1 GW of capacity.

When most of today’s wind projects were developed, first costs were the focus; operations and maintenance (O&M) costs were largely unknown. Now, with hundreds of turbine models in operation—sometimes ...

For many environmental enthusiasts, horizontal-axis wind turbines (HAWTs) — the kind that look like windmills slowly spinning in the distance — are a pretty familiar sight. Unfortunately, there are ...
