Great Britain
In the period 2005-2009, 13 514 small wind turbines up to 20 kW
were installed. The British Wind Energy Association (BWEA)
estimates that 600 000 windmills of max. 50 kW will be installed by
2020. Only in 2011, 23 MW of small wind turbines were installed
in Britain, making Britain ahead of the United States in terms of
installed capacity (in the United States it was 19 MW in
2011). New feed-in tarif program was implemented in April
2010 Microgeneration Certification Scheme) with price of
0.21 GBP/kWh (0.241 EUR/kWh) for wind turbines up to 100 kW.
However, new feed-in tarif revisions introduced in December
2012 reduce existing tarifs to:
• 0.152 GBP/kWh (0.174 EUR/kWh), 42% reduction of price
for wind turbines up to 1.5 kW
• 0.070 GBP/kWh (0.080 EUR/kWh), 25% reduction for wind
turbines of 1.5 kW to 15 kW
• 0.043 GBP/kWh (0.049 EUR/kWh), 17% reduction for
turbines from 15 kW to 100 kW
The United States
In 2011, more than 19 MW capacity small wind turbines were
installed in the United States.
It is expected that by 2013 there will be 650 MW small windmills
installed (26 000 units, average capacity 25 kW) with eight-year
favourable tax-credit incentives.
According to AWEA,
the US small wind turbine market (up to
100 kW) decreased by 26% (in MW) in 2011. However, domestic
sales and export of wind turbines manufactured in the United
States increased by 13.4% (to 33 MW).
There is a growing interest for do-it-yourself small wind
turbines of 1 kW or less capacity. Construction of home-made open-
source wind turbines has been made popular through construction
guides, magazines, web sites and TV series.

After the Fukushima disaster in March 2011, Japan strives to
increase the share of renewable energy (wind and solar) in power
