Wind Turbines Only Generate Power Between 6 MPH and 50 MPH

Wind Turbines Only Generate Power Between 6 MPH and 50 MPH

Renewable energy experts say a single standard 10 megawatt ocean wind turbine can power up to around 13,000 homes. The problem is the wind would have to blow 49 mph 24/7.
This statement means that the maximum power at perfect conditions of wind speeds of around 49 miles per hour the turbine generates the maximum amount of its power. A 10 megawatt wind turbine will generate enough power for 13,000 homes. Each megawatt of a 10 megawatt turbines equals around 1300 homes. 
Wind turbines only operate between the cut in and cut out speeds usually 6 miles per hour to 50 miles per hour.
Wind turbine cut-in speed is the minimum wind speed required to make the blades start rotating and generate the minimum amount of power at around 6 miles per hour. 
Wind turbine cut-out speed is the maximum wind speed and generation that a wind turbine can handle before it shuts down using its brakes to prevent damage around 50 miles per hour. Sudden wind gust from different directions can also shut down a wind turbine. 
Wind generation formula in general : 
At below 6 mph: no power 
At above 10 mph: 1 megawatt   
At above 20 mph: 3 megawatts 
At above 30 mph: 5 megawatts 
At above 40 mph: 8 megawatts 
At 49 mph:             10 megawatts 
At above 50 mph: no power  brakes on 
During hot summer days it is possible to have very little generation from a wind farm. 
During winter months during winter storms it is possible to have very little generation.
Note # Wind turbines have an addition issue the same of all power plants. It's called parasitic load. A  single wind turbine needs its own power or an outside source to run heaters, brakes, air conditioning, de-icing elements for blades, rechargeable battery banks, computers and communication equipment which could take 10 to 15 percent of its own power. 
Note #  Most wind turbine manufactures do not include the parasitic power usage in the power ratings of their own wind turbines. 
The bottom line :   Wind energy produces costly, intermittent, unpredictable electricity

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?

We have the facts on our side. We have the truth on our side. All we need now is YOU.
