Kent Hawkins has a further post at Master Resource examining the effects of wind power on overall emissions produced in a power system.
In the post Hawkins examines the Michael Milligan et al, article, “Wind Power Myths Debunked,” appearing in the most recent IEEE Power and Energy Magazine (an article mentioned in comments I made here pointing out Hawkins’s earlier post). The “debunking” of Milligan et al seeks to portray many issues raised with respect to wind power as less important than wind power critics assert.
Hawkins’s response aims to debunk the debunking. If you are inclined to rely on the Milligan et al article, you ought to consider the objections raised by Hawkins seriously.
