News & Articles on Large Wind Power
Large wind turbines are those used to generate commercial quantities of electricity. This category includes single turbines used in distributed applications as well as arrays of multiple wind turbines used in a wind power plant.

In 1997, Canadian meteorologist Jim Salmon reported that a 50 kW DAF-Indal turbine at Christopher Point, on the southern tip …
Are airborne wind turbines (kitess) a plausible source of cheap clean energy?

An ongoing area of enthusiasm and often fruitless investment is the area of high-altitude wind generation. Numerous companies have products which are hyped as replacing the iconic white tower with three rotating blades that grace 240,000 individual sites around the world today. At most, some of these products will be useful in high-cost niches where more cost effective alternatives have very specific limitations.

What is the most efficient design for a wind generator?
By
Mike Barnard
It seems as if every week, a new wind generator innovation is unveiled, sometimes in technology blogs, sometimes in TV segments, once even on TED Talks. They all claim to be better than the iconic, triblade, horizontal-axis wind turbines we are most familiar with. So what is the most efficient design for capturing wind energy? If each design were subject to a constant wind source, and each design had the same surface area (for blades, aerofoils, or other component), which would generate the most electricity over the same time interval?. .
