The Transition to Decentralised Power in
Denmark
The diference between fossil energy and renewable energy
forms is that the latter aredecentralised by nature. Thus, a small
number of large-scale wind turbines for energy production may be
replaced by a large number of small ones. In principle, any building,
house or farm can produce energy from renewable sources, which
turns out to be cheaper than production from fossil forms of
energy. Wherever wind resources are available, costs of electricity
generated by small-wind windmills will be higher than from large
windmills, however, generally lower compared to photovoltaics.
In Denmark small wind turbines (household wind turbines)
are defined by the Danish Energy Agency (DEA): maximum height
from base to the blade tip is 25 m; rotor diameter up to 13 m;
maximal size of the generator is 25 kW; maximum capacity is
6 kW and 40m

swept area are principles for net-metering
(electric meter reverses). Small wind turbines are to be installed in
private households, nearby and connected to existing buildingsfor
