future costs of electricity generation
Figure 6.34 shows that the introduction of renewable technologies under the Energy [R]evolution Scenario significantly decreases the future costs of electricity generation compared to the Reference Scenario. Because of the lower CO2 intensity of electricity generation, costs will become economically favourable under the Energy [R]evolution Scenario. By 2050 generation costs will be more than 8 cents/kWh below those in the Reference Scenario.
Under the Reference Scenario, on the other hand, 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 $70 billion per year to more than $551 bn in 2050. Figure 6.35 shows that the Energy [R]evolution Scenario not only complies with Latin America’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 leads to long term costs for electricity supply that are one third lower than in the Reference Scenario.
