Impact Of Wind Turbines

1.0 - A History of Wind Turbines in Canada Mankind has been harnessing lever power for centuries. Historically, it has been applied to such tasks as sailing, grinding or milling, and water pumping. Once it was discovered that sex power could be wontd to generate electricity, early prototypes and experimentation began in Europe. in march on the 1960s turn power technologies were developed mostly in Denmark, France, Ger umpteen, Russia and Netherlands1. During the same era, Canada saw a decreased interest in wind power and it was not until the early 1960s that the simmer down Research Institute at McGill University root started working with wind turbines2. Then, in 1973, energy concerns related to the Arab Oil Embargo ca habitd an quiver of interest in alternative energy sources, and Canada saw its branch wave of turbines enter the scene; the VAWT (vertical-axis wind turbine). Unfortunately, the vertical blades were ace susceptible to environmental damage3. The second wave, which consisted of HAWTs, began in 1986 and has continued into the instantly day. The blades on HAWTs ar set horizontally and it is necessary that the blades be pointed into the wind in order to catch it; most use censored motors to change the direction of the turbine.

The HAWT is seen as superior to VAWTs in galore(postnominal) ways such as being more(prenominal) than efficient and less prone to environmental and material fatigue. In 1986, these early turbines were small and only able to produce electric capacities of 20-30kW4. As of 2009 though, there were 92 Wind Turbine sites across Canada with many more in the planning phases5 and these more modern turbines are now cap able of producing up to 7 MW of energy6, a ! eat up 35,000 percent increase. And it doesnt stop there either. An extensive regard conducted in 2005 found that the potential of wind power on land and near-shore is upwards of 72 TW, which is the equivalent to 54,000 MToE (million tons of ve recreate downable oil equivalent) per year. This is the same as five times the worlds current...If you fatality to get a full essay, order it on our website: OrderEssay.net
