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]
One of the persistent myths of wind energy is that vertical axis wind turbines (VAWTs) are better than the iconic three-bladed horizontal axis wind turbine (HAWTs). A wrinkle on this myth has surfaced over the past couple of years, that the balance of engineering compromises favours VAWTs for offshore applications. … [continued]
Wind Power Limited has released its plans for a new and improved Aerogenerator vertical axis wind turbine (VAWT). The company is saying that the new prototype can generate two times more power than the original, while only weighing half as much. According to the company, “the Aerogenerator X is … [continued]
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) […]
Keele University recently had a new “flat pack” wind turbine installed on its campus. It is intended to address the problems that wind turbine setups have in urban areas. McCamley UK installed the turbine, which is the first of that product line to be installed in the UK, but previously, … [continued]
Chicago’s the “Windy City,” but EWP’s betting that, sited atop Boston high-rises, its vertical-axis wind turbines can make a sizable dent in buildings’ energy costs. […]
Some more top cleantech news from the past day or so. Solar 1. We’ve written about the large solar boat known as Planetsolar many times in the past. Our good old friend Tim Hurst of Live Oak Media delved into the boats features in good depth in a recent … [continued]
OK, one more roundup post here — following up on my roundups of 10 new cleantech projects, 10 new cleantech consumer products, and 7 green jobs stories roundups, this one is on 10 new cleantech technologies in the works or just out. Zep Solar recently released an innovative mounting system for … [continued]
Wind energy is growing in use across the U.S., both small and large wind turbines are getting installed at record rates. And the trend is similar across the world. A new report by Transparency Market Research, “Global Wind Energy & Wind Turbine Market (2011 – 2016),” finds that there’s been a Compound Average Growth … [continued]
