You'll have to do more than that to win us over Tesco - like stop trying to take over the country or start paying UK tax on money you take from people in this country.

A 10m high turbine there is only going to experience an average of 5.1m/s wind, which really isn't very useful.....

How much energy would they save if they simply closed the stores at night?

Do we really need 24-hour super stores?

Of course a 10m high turbine would not say "HERE IS TESCO" to passers by. Sounds to me like an advertising ploy.

It might be another form of small-scale renewable would suit:

Good point.
I've no doubt the TESCO board when discussing it said good idea it might do nothing for the environment but it will provide a very visible advert for our store.
They have already got mention (a free advert) in The Scotsman
