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 ...

Wind turbines that swap traditional mechanical drivetrains for hydraulics could potentially be lighter, more reliable, and less expensive than those fielded today. • A nacelle-mounted hydraulic ...

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 ...

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).

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 ...

As the world innovates to become more sustainable and electrified, the demand for renewable energy generation grows. Wind energy has become key in increasing the renewable energy generation mix of ...

Offshore wind turbines could house up to a 12-megawatt data center, drawing wind power while using the cold sea water for cooling.

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 ...

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, ...

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 ...
