These are small-scale wind turbines installed for residential and small buildings. Small wind turbines (SWT) are now bigger, its average size increased from 500 W to 1 kW. In the US, the use of SWT is gaining momentum in the rural and farming areas, and for grid-connected onsite distributed generation applications. Installed capacity of SWT is still small relative to the overall wind energy sector. There is only an estimated 30 MW of installed capacity in the US in 2004. This is less than one percent of the total installed capacity in the United States of 6,740 MW. Four U.S. SWT makers supply one-third of global demand. The SWT sector is expecting good growth in the short to mid-term. 2005 had projected global sales of about 13,000 units of SWT of up to 100 kW. This is translated to about US$25.0 million in sales. Looking further ahead, 150,000 units of SWTs are expected to be installed from 2006 to 2010. Sales generated in that period are an estimated US$110.0 million. The total installed capacity at end 2010 is a projected 350 MW. The overall wind energy sector, though, is projecting an installed capacity of 134 GW by 2010. Meanwhile, installed costs of SWT are expected to be reduced by 20.0% to US$1,700 per kW by 2010.
