All those points were addressed by Thomas at the top of a different subthread.

ChrisCook:

a great deal of Danish wind power is actually exported, and reduces carbon fuel consumption and emissions elsewhere.

Thomas:

It is exported.. primarily to Norway and Sweden, neither of which have any significant amount of carbon emitting generation capacity at all.  Net ecological  gain: Zero. Net economic cost to Denmark of using nordic hydro to loadbalance our wind capacity? Quite large. Danish wind electricity importsexports are mostly used to conserve waterhead behind dams in Norway and Sweden - this reserve of power is then exported back to us when wind is low at a much higher price. Which means two things - that the actual percentage of wind in the danish power mix is in fact rather higher than export statistics indicate, and that the price of this electricity, including storage outside our borders, is much higher than we admit.

ChrisCook:

It also thereby reduces the profits of carbon-fired generators of course which accounts for some of the misleading propaganda.

Proponents of nuclear have no such excuses.

Thomas:

French power exports, which are typically a heck of a lot larger, go to countries that do use coal. Net ecological gain: Large.
