the United States and Europe, probably one-fourth or more of the small wind turbine capacity is grid
connected. In China [5] and other developing countries, most are stand-alone systems for households,
50-300 W. So the numbers reported for production of small wind turbines will include all areas. A
very rough estimate for global number of small wind turbines (50-100 kW) is 550,000 to 625,000
with a capacity of 200-250 MW (Table 10.4). The wide range is due to unknown accuracy of the
production in China of 150,000 units in the 4 years 2004-2007 (most in the 300 W size).
There are approximately 100 manufacturers, with around 40 in Europe [6] and 30 in China. The
largest production was in China, with 51,000 units in 2006, of which 16,000 were exported [7], primar-
ily to other Asian countries. In the past, most of the Chinese production was 50-100 W wind turbines
