In-Depth Information
In the first Danish energy plan from 1976, wind power and
other renewable energy sources were nearly absent. Coal, nuclear
power and natural gas were considered as the only possible
substitutes for expensive oil. This attitude was supported by
Danish utilities, big industries and big political majority in the
Danish parliament [13]. But wind power was re-invented by
local blacksmiths, students, independent researchers and other
innovative persons. The inspiration could be found—not in the
official plans, but in the history and it was visible in the Danish
landscape. At Gedser, near the southern-most point of Denmark,
Juul's 200 kW experimental wind turbine could still be seen—
though out of service since 1967. Close to it an even older 3-bladed
FLS Aeromotor from the last World War was also still standing.
And in many other places in the landscape—not at least in
northwestern Jutland at the other end of the country—some of the
more than 15 000 windmills once used on Danish farms were still
visible in the landscape. A few of them were still in use for grinding
grain and many local craftsmen had the experience of doing service
and repair work on these types of windmills.

There were no suppliers of wind turbine technology on the
market and the new Danish wind power pioneers started from
scratch with parts from scrap dealers. A rear axle from a car or
a truck was a favourite part of the transmission in many of the
new wind turbines (Photo: Benny Christensen, DVS).
