who to blame

ok 2 questionswhat is the minimum wind speed needed to generate 1 kw of power ?

 

what is the maximum wind speed that wind turbines shut down ?

The ones I've seen not rotating are generally shut down as there is no requirement for their power at that time. You will see some going and others not. This must aid in balancing the output to the load, I would think. Coal plants are not as efficient (and may also fail) on a very hot day. Coal isn't the answer to the problem. we haven't built new ones for years. The super critical ones take a long time to fire up and only work efficiently at a set output, near their Maximum. As they are a high capital cost, they won't be performing a standby function either. Nev

The short answer if you are not up for watching the clip I posted is:

 

At wind = 3 metres per second (10 kph) = 22KWh

 

At 5 mps (18kph) = 110KWh

 

At 14 mps (50kph) = 2MWh

 

Max speed or cut off is at 21 mps (75kpm)
