Nice trend, but what is the energy generated?
Still pretty insignificant in the overall picture.  Canada's gross electric power generation in 2002 was around 500,000 GWh. For one wind generating station in Alberta, the capacity factor is around 32%, which would be pretty much at the high end of the range. Scaling that up suggests that the total generation from the 1049 MW installed base is probably less than 3,000 GWh
