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 ...

When you consider today’s industrial wind turbine, you likely picture the windmill design, technically known as a horizontal-axis wind turbine (HAWT). But the very first wind turbines, which ...

[Photo: World Wide Wind] How it works. The concept of vertical axis turbines is not new, but the architecture of this machine—which the company says is patent pending—is radically different.

Horizontal-axis turbines come in a number of different styles and designs. These can harness the wind’s energy from multiple angles, so they don’t need to be adjusted when the wind changes ...

Vertical-axis wind turbines have failed to make a dent in the thriving global wind energy business. But proponents say VAWTs may be particularly well suited to the emerging floating offshore market.

VAWTs spin around an axis vertical to the ground, and the team asserts that if they’re set in pairs, they’d be 15% more efficient because the wind turbines would increase each other’s ...

Traditionally, turbines take the form of Horizontal Axis Wind Turbines (HAWTs). However, the research now proposes that Vertical Axis Wind Turbines (VAWTs) — which are more compact in design ...

Wind now accounts for 7.2% of power generated in the United States, and IceWind says that will be around 20% in less than a decade, by 2030. But most of that is the huge horizontal turbines you ...
