expected to fall to one third of today’s costs; hydropower was
assumed to remain on current cost levels.
The “Fast Exit Scenario” shows an increase of renewable
generating capacities from less than 200 MW in 2006 to about 6400
MW in 2030 and further to almost 12,000 MW in 2050. Wind energy
contributes most to the total renewable capacity—almost three
fourths ...
