When thinking of small-scale renewable energy solutions, particularly for off-grid projects, solar is the first thing that comes to mind. Whether a ground-mount or roof-mounted system, the availability, falling costs, and simplicity of the solution has thus far been attractive for customers. Wind, on the other hand, is often still … [continued]
A sleek new design for a floating offshore wind turbine cuts the cost of wind power by cutting mass to the bone.
A new floating offshore wind turbine deploys vertical axis technology to cut costs and simplify the supply chain.
Vertical axis wind turbines will soon be coming to a rooftop (or ocean) near you, if all goes according to plan.
Vertical axis wind turbines could find a new home in offshore wind farms, where density, reliability and ease of maintenance give them an edge over conventional wind turbines.
Have you ever noticed energy blogs or articles about small wind turbines comparing them directly with big wind technology and solar? I am writing this article to provide a little background on where small wind turbines can be very successful and where they make absolutely no sense. It also explains … [continued]
Stability, ease of maintenance and power generation capacity are selling points for MODEC’s new SQWID ocean energy platform, which combines Darreus and Savonius turbine designs.
Wind and solar energy are being harnessed and integrated with electric vehicle chargers, heralding the coming end of the “Fossil Fuel Era” and the onset of a new age of sustainable, renewable power and fuel for transport. Two news items this past week– one regarding the Sanya Skypump and another regarding Envision Solar Trees– foreshadow what’s to come.
Do the best offshore wind turbines operate with a horizontal or vertical-axis mechanism? That question is being reexamined by Sandia National Laboratories’ wind energy researchers, who are now re-evaluating vertical-axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes using horizontal-axis wind turbines (HAWTs) […]
The London 2012 Olympic Games are being heralded as the “greenest games ever,” and one of the latest green boosts to the game has come to the centre of the Games, Olympic Park, home to eight Olympic venues, including the Olympic Stadium, Aquatics Centre, and Velodrome, and now seven … [continued]
