An oil industry myth. The bigger the wind turbine the faster it pays out the energy needed to make it. Only 64 days for a 3.4 MW turbine

He says a lot more than that in that scene...not that I buy all of it, just thought there was some interesting points brought up.

I'm sorry, but those numbers don't even come close to passing the sniff test.

E.g.:

----------------------------

Alternatively, energy payback may be measured by ‘number of times payback’ – meaning, the amount of energy paid back to society versus the energy needed in the lifetime of that turbine. Over the life cycle of a V117-4.2 MW wind power plant, it will return 50 times more energy back to society than it consumed.  

That means that when 1 kWh is invested in a wind energy solution, you get 50 kWh in return. For coal, however, if you invest 1kWh you typically get below 0.4 kWh in return.

------------------------

They're honestly asserting that the trillions of $ invested in the coal and oil industries have provided *negative* energy returns?    That makes no sense.

Given the source though - a windmill manufacturer - it doesn't surprise me.   Much like the oil industry shills - they have a vested interest (no pun intended) in making competing technologies look bad.
