Was actually referring to the ones in B&Q

That doesn't alter the fact that the energy used to make them will
be recovered, except in the strangest of circumstances.

Obviously it is likely that such turbines will not be ideally
situated in many cases and they will not be as efficient at
converting wind into electricity as a large turbine. Thus it is
likely that they will take longer to recover the energy used to make
them, let's say a year to be generous.

That is an energy balance however. A financial balance is a
different thing. I expect that, as with almost anything else, the
early adopters will have other reasons for purchase and that the
result of their purchases will be to drive the cost down.
