World wind power capacity has well and truly passed the 8000 MW milestone. Caution must be exercised in using the quarterly differences in Windicator totals to track trends, but the extra 600 MW added to the overall total this quarter is by far the largest yet recorded. It brings global wind power generating capacity close to 8500 MW. For the second quarter running, the United States is back in the top five most active markets, a considerable change from the stagnation of recent years. Germany and Denmark still lead the way in the development stakes, well out in front of Spain, Italy, Sweden and the US. Conventional wisdom in wind circles holds that global capacity will double every three years. At today's rate of development, that may turn out to be conservative.
