Danish energy supply is traditionally based on fossil
fuels. Denmark has very little hydro power potential and
during the 60 and 70 s, the electricity supply was dominated
by large steam turbines located near the big cities.
However, after the first oil crisis, Denmark has become a
leading country in terms of implementing CHP, energy
conservation and renewable energy. Consequently, the
Danish energy system has been changed from a situation in
1972, in which 92% out of a total of 833 PJ was oil, into a
situation of today in which only 41% out of 828 PJ is oil. In
the same period, both transportation and electricity
consumption as well as the heated space area have
increased substantially. Today, the share of electricity
production from CHP is as high as 50%, and approximately 20% of the electricity demand is supplied by wind
power[24–29]. Fig. 4 illustrates the development from 1972
until today and shows the outlook for the future in
accordance with the reference scenario explained in the
following.
When analysing the possibilities of continuing the
development and replacing more fossil fuels by renewable
energy, two problems arise.
One problem is the transportation sector, which is
almost totally fuelled by oil. Consumptions have been
increasing from 140 PJ in 1972 to an expected 180 PJ or
more in 2020. Thus, the transportation sector accounts for
almost all of the expected oil consumption.
