future costs of electricity generation
Figure 6.37 shows that the introduction of renewable technologies under the Energy [R]evolution scenario slightly increases the costs of electricity generation compared to the Reference scenario.This difference will be less than 1 cent/kWh up to 2020, however. Because of the lower CO2 intensity of electricity generation, electricity generation costs will become economically favourable under the Energy [R]evolution scenario by 2020, and by 2050 costs will be more than 4 cents/kWh below those in the Reference scenario.
Under the Reference scenario, the unchecked growth in demand, the increase in fossil fuel prices and the cost of CO2 emissions result in total electricity supply costs rising from today’s $309 billion per year to more than $685 billion in 2050. Figure 6.37 shows that the Energy [R]evolution scenario not only complies with Europe ́s CO2 reduction targets but also helps to stabilise energy costs and relieve the economic pressure on society. Increasing energy efficiency and shifting energy supply to renewables lead to long term costs for electricity supply that are one third lower than in the Reference scenario.
In both Energy [R]evolution scenarios the specific generation costs are almost on the same level until 2030. In 2050 the advanced Energy [R]evolution scenario has with 8 cents/kWh lower generation costs, because of better economics of scale in renewable power equipment.
