Anybody know the answers to these? If possible sources for answers.

Regarding wind turbines:

Roughly, what do they cost to put up initially (including subsidies)?

Once built, does the value of energy produced exceed the value of operations and maintenance costs?

Is the energy produced directly transferred to the power grid, or is it stored on site and exported later?

How much is produced annually, and what assumptions accompany this estimate (eg. 24X7X365 ops, etc)?

If you used the entire electrical output of the wind turbine to perform electrolysis on water to produce H2, how much potential electrical energy would be lost? Or said differently, what is the potential electrical energy contained by the H2 vs. that electrical energy derived directly from the turbine?

Thanks in advance for your thoughts.
