Wind power involves taking the kinetic energy of air movement and converting it to electrical energy using the aerodynamic blades connected to an alternator/generator.
The energy available in the wind varies with the wind speed cubed. This means if you double the wind speed, the energy increases by a factor of eight (2x2x2).
Smooth, non-turbulent air is needed to maximize power extraction and to reduce unnecessary wear to turbine components. This is why it’s unwise to position a wind turbine close to the ground or any obstruction. The fuel is up there!
“With great power comes great responsibility”
While the industry is constantly innovating to improve turbine technology, not all innovations are successful or even useful. We come across several innovators claiming impossible power curves. In order to weed out such unproven technology, the Distributed Wind industry has instated the Small Wind Certification Council (SWCC) and Interstate Turbine Advisory Council (ITAC).
We only install turbines certified to AWEA 9.1 or IEC 61400 standards by independent testing agencies and listed on the Interstate Turbine Advisory Council (ITAC) unified list of Turbines
Bergey Windpower is the oldest and most experienced manufacturer of residential-sized wind turbines in the world.
Thirty years ago Bergey pioneered the radically-simple “Bergey design” that has proven to provide the best reliability, performance, service life, and value of all of the hundreds of competitive products that have come and gone in that time. With only three moving parts and no scheduled maintenance necessary, the Bergey 10 kW has compiled a service record that no other wind turbine can match.
Osiris 10 offers the shortest payback period in the 10kW small wind turbine market. With blade lengths of 9.7 meters providing wider swept area, Osiris 10 offers higher annual production at competitive prices

GE’s 1.6/1.7-100 wind turbines offer a 47% increase in swept area when compared to the 1.6-82.5 turbine, resulting in 20% increase for the 1.6-100 and 24% increase for the 1.7-100 AEP at 7.5 m/s. This increase in blade swept area allows greater energy capture and improved project economics. GE’s 1.6-100 turbine has a 54% and the 1.7-100 turbine has a 53% gross capacity factor at 7.5 m/s—a class leading performance.
GE’s 1.85-87 wind turbine is designed for Class S winds, targeting 8.5 m/s, and offering an 11% increase in swept area and an extra 150 kW output at rated wind speed compared to the 1.6-82.5 turbine—resulting in a 10% increase in Annual Energy Production (AEP) at 8.5 m/s. This increase in blade swept area allows greater energy capture and extra output at rated wind speed, and drives improved project economics for wind developers.
