Thank you, now we're getting somewhere. I ran the numbers,
On average, 20 GJ of energy is consumed per tonne of crude steel produced globally
each new MW of wind power requires *120 to 180 tons of steel.
Say 150 tons, that's 3000 GJ needed for the steel per MW wind plant.
For a 1 MW nameplate capacity offshore wind, the average joules per minute will be in the range of 24 to 30 MJ/minute. I calculate this to be a 70 day period at max output to generate the 3000GJ for the steel required to build it. So it seems you are correct in your assertions as to the efficacy of Wind power to cover the costs of construction and give a massive return on investment. Again, thank you for your efforts.
