While wind is ok, is should not be the future. It's a cheap solution, rather than investing in real green power like tidal which is always there, not weather dependent.
The analysis also fails to mention the cost of infrastructure for wind, instead using an unreferenced figure for savings on gas infrastructure.
Also, it fails to mention that wind energy is charged at the rate that it would cost to generate by gas...
So we SHOULD have seen bill reductions due to wind but have not.
