Actually, the net effect on consumers of wind is to _lower_ prices for them, as, when wind blows, the marginal price is much lower and applies to all the power generated. The savings to consumers from lower prices when wind blows are already larger than the gross amount of the subsidy given to wind in countries like Denmark, Germany or Spain (and of course, even larger than the net subsidy which is the feed-in tariff minus the market price). So focusing only on the tariff while ignoring the simultaneous effect on market prices is silly.

Ironically, this means that wind will always require a regulated tariff as, the more wind you put in the system, the lower market prices will be (when wind reaches 50-100% of system needs as is already happening in Denmark or Spain, prices come down to almost zero) and wind can never be profitable under "pure" market conditions. So you need wind farms to keep on getting a steady revenue in order to be built; the good thing is that the tariff reuired can be quite low (in the same range as market prices are today) and never needs to be increased.
