Endurance commissioned its first E-3120 50 kW wind turbine in January 2010.

Small wind fleet hits over 2 million hours in less than 3 yrs

A manufacturer of advanced distributed 5 to 50 kW wind turbines and future manufacturer of Norwin’s mid-size wind turbines, is pleased to announce that its E-3120, 50 kW wind turbine has successfully reached more than two million fleet hours of operation in less than three years.

White paper: Wind turbine generator safety compliance in the U.S and Canada

A report published by Intertek: Wind Turbine Generator Safety Compliance in the United States and Canada, identifies the most common issues faced by manufacturers of wind turbine generators and components and providing them, as well as customers and investors, with information on how to improve the overall wind turbine, product-safety certification. The white paper, authored

The big guys learn financing from the little ones

Community wind projects provide a wealth of information about what works and what doesn’t when financing a utility-scale project.

Scott Merrick (with glasses) talks to an attendee at the Bergey Windpower booth at Wind and Solar Expo. The company’s XL.1, a 1kW battery-charger turbine sits to the right. He says the turbine will be available as a direct grid-tied version within a year.

Small wind a big part of Solar and Wind Expo

Small wind was a highlight of the Solar and Wind Expo (www.thesolarandwindexpo.com) a consumer-oriented renewable energy event recently held in Baltimore. Several small-wind companies exhibiting were enthusiastic about the event and its attendees. “They came to see and learn about the latest in renewable energy equipment,” said Gary K. Sorrelle, a wind specialist with Atech

The SET is the work of U.K. inventor Rupert Sweet-Escott, whose would like to put “a SET on every house.”  The turbines range in power from 50 to 250 watts and start around $1,132.00.

Is it a chimney…or a turbine?

Wind turbines on houses are not always practical because some home owner associations would object to the noise it might make, or neighborhoods that restrict changes in aesthetics. A U.K. inventor may have solved the problem with a design called the Secret Energy Turbine (SET) because it disguises the turbine as part of a chimney.

Small wind certification testing goes regional

The DOE recently announced the selection of four partners to establish small wind Regional Test Centers (RTCs) to conduct tests on small wind turbines to meet national and international standards.  These awards provide funding, training, and technical support for each Regional Test Center so they may conduct testing on two small wind turbines to support

Analyzing building-integrated wind

Russell M. Tencer/CEO, Wind Products LLC/New York, NY Controversy seems to follow the installation of wind turbines on building rooftops, and for good reason. On one hand, there can be considerable wind with harvestable kinetic energy at roof level. Accessing this clean, renewable source of power can be a good way for building owners to

The Earth Turbine 2500 can generate 2.5 kW in a 11 m/s wind.

Wind-turbine manufacturer adds solar interest, changes name

Earth Turbines Inc, Williston, Vermont, the state’s only manufacturer of small scale grid-connected wind and solar tracking systems, announces a corporate name change to AllEarth Renewables Inc. “Our company is dedicated to developing new wind and solar technologies,” says David Blittersdorf, CEO and president of AllEarth Renewables.  ”We want to be sure that our corporate

3.5 KW turbine with smart technology

Cleanfield Energy adds Smart controls to turbines

A 3.5kW vertical-axis wind turbine is said to produce clean, reliable energy for residential and commercial applications. The system can mount on flat rooftops, as well as traditional towers and poles. The V3.5 from Cleanfield Energy, Ancaster, Ontario, Canada, can be installed without the need to change existing wiring, and can be used for both

The S-shaped blades are tapered to shed noise. The helical design captures turbulent winds and eliminates vibration. The blades, spars, and torque tube are made of durable carbon fiber and all moving parts are sealed to minimize maintenance. The direct drive inline generator has built in auto shutdown and peak power tracking.

Vertical axis turbine works well atop office building

One forecast for small scale wind generators (sometimes called microgeneration) has them providing 30 to 40% of all the UK’s electricity needs by 2050. The British Wind Energy Association hints that with price trends for crude oil continuing up, the cost of small scale wind could be competitive with fossil fuels by as early as
