Propeller wind turbines are the most common way of using one of the most abundant energy sources on Earth to generate electricity. The tall three-bladed fans are the ubiquitous symbol of wind energy, ...

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 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, ...

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 ...

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 ...

3 days China’s Coal Output Hits Record High Even as Coal-Fired Power Declines 3 days China’s Coal and Gas Power Output Falls for the First Time in a Decade 3 days Philippines Makes Its First Gas ...

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 ...

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 ...

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 ...

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 ...

When you think of a wind turbine, the image that likely pops into your mind is the classic three-bladed giant rising from farmland or the sea. But over the years, designers and engineers have come up ...
