I think the main point the article was eluding to was that if you use wind power to first generate electricity then convert this into heat, you have two conversion steps with loss: wind to electricity, and then electricity to heat. The overall efficiency is then the product of the efficiencies of the two steps. If you produce heat directly from wind, you cut out one conversion with its associated inefficiency.

I always figured electricity to heat was nearly 100% efficient, it's the generating of electricity where the losses occur.
