Ok, so this investment will supply 1.4 M homes. How much investment is this - in GB pounds ?. Divide by 1.4M and we have the investment of each home. My question is "What are the chances of anyone being able to repay that ?"
Again they talk of Watts, and not Joules. So now and then these "turbines" as they like to call them, put slightly over 4MW each into the county's grid, (or so we have to believe) if the wind happens to be being accomodating. This is a meaningless figure untill we know how for many hours this - or some average - output is maintained !!
A very sensible design of wind turbine-alternator device - TAD ? - can be shown, logically, to be about 1/40th of the cost per watt, and will readily return 5% of its actual cost, per annum. I define "very sensible" design as one which supplies a full half of the entire k.e. of the wind as watts into an electrical load.

Apologies for my last comment being slightly off-track. These are wave and tidal schemes, not "wind turbines" !!. It's late. I'm tired.
Still, can anyone answer my question ? My guess of an answer is "maybe, just maybe !" But the point that matters is will the things last long-enough to pay for themselves - several times over ? And how long will this be ? After that the patient and persevering owners will have a serious Goose ! But it's those initial investors that are required. It is very sad to see good money - energy - resourses - being thrown into junk that "looks good" i.e. impresses and cheers those concerned about global warming, i.e. "windfarms" !!
