generation by increasing investments in the sector and intro-
duction of a new feed-in tarif in July 2012. The feed-in tarif is
applied to small-scale wind power and solar energy installations
and requires power utilities to buy back electricity generated
from wind and solar energy at prices set by the government.
Small-scale wind turbines (of less than 20 kW capacity) will be
subsidised at least JPY 57.75/kWh (about USD 0.74/kWh).

There are over 200 000 homes in the open land the Danish that
depend on heating from oil. It is the government's policy to phase
out oil. With small windmills installed at 10% of the 300 000
homes in the open land the Danish market potential is 30 000 small
windmills. Net-metering for small wind power up to 6 kW has
been introduced in June 2010.
Danish small windmills: approximately 300 units; in 2011, one
year after new legislation, there were about 300 units installed.
In the country there are 20 manufacturers and suppliers of small
wind turbines.
In Sweden approximately 1 100 small windmills are in operation.
There are 12 manufacturers of small wind turbines in the country.
In Finland there are slightly less than thousand small wind turbines
operating, whereas there are only two manufacturers.
