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.

Small Wind Turbine Size to Meet Household Consumption

By

Paul Gipe

You can’t get something for nothing. North Americans who think a micro or mini wind turbine will meet all their household consumption are in for a rude surprise. A wind turbine with a rotor 1-2 meters in diameter (3-7 ft) will not provide a significant portion of their domestic electricity consumption unless they are extremely conservation minded.

Toronto’s WindShare cooperative. WindShare’s more than 400 members own one half of the wind turbine. Toronto Hydro, the municipal utility owns the other half. The Lagerwey 52 meter (170 foot) diameter wind turbine stands at a prominent location overlooking the Gardiner Expressway in Canada’s largest city. The first urban wind turbine in North America, it has became a beacon for renewable energy advocates across the continent. 2009.

Generator Ratings & Capacity Factors: Why You Should Avoid Them

By

Paul Gipe

Newcomers to wind energy and even some old-timers who should know better often equate the size of a wind turbine to it’s generator rating. A Vestas V80 for example is rated at 1.8 MW; a V82 is rated at 1.65 MW. While this is may be a useful shorthand among those unfamiliar with wind energy, the use of generator size leads to a host of problems when evaluating the technology.

Typical of rooftop turbines, the rotor is tied down on this non operating turbine in Holzhausen, Rheinland Pfalz, 2005. The turbine is noteworthy in its own right. The turbine is probably an Allgaier built in the years from 1950 1959. It appears to be a twin to a turbine atop the same company's building, Klöckner Moeller, alongside the main north south line from Bonn to Koblenz. The Allgaier was a derivative of the work by the father of German wind energy, Ulrich Hütter, and was built by a small company in the south of Germany in Göppingen (near Uhingen). Altogether, there were about 200 units built and ranged in size from 6 10 kW. A photograph similar to this and this background information is contained in Windgeshichter by Jan Oelker, 2005.

Wind’s Up: Planning the Future Now

By

Mark Ashby

The Resource Management Act, plans developed under it, and RMA processes are capable of facilitating wind energy development and of dealing with the range of effects associated with a wind farm. However, if wind energy development proceeds at the pace and reaches the levels experienced in places such as Western Europe, an ad hoc approach to the planning issues will not maximise benefits and minimise problems. Sustainable development needs integrated management, and integrated management requires a strategic approach at all levels of government.
