Scenarios for a future energy supply

Moving from principles to action for energy supply that mitigates against climate change requires a long-term perspective. Energy infrastructure takes time to build up; new energy technologies take time to develop. Policy shifts often also need many years to take effect. In most world regions the transformation from fossil to renewable energies will require additional investment and higher supply costs over about twenty years

6.4 future investment

It would require US$ 457 billion in investment for the Advanced Energy [R]evolution scenario to become reality (including investments for replacement after the economic lifetime of the plants) - approximately US$ 160 billion annual or US$ 4 billion less than in the Reference scenario (US$ 617 billion). Under the Reference version, the levels of investment in nuclear power plants add up to almost 74% while approximately 20% would be invested in renewable energy and cogeneration until 2050. Under the Advanced scenario, however, South Korea would shift almost 90% of the entire investment towards renewables and cogeneration. Until 2030 the fossil fuel share of power sector investment would be focused mainly on combined heat and power plants. The average annual investment in the power sector under the Advanced Energy [R]evolution scenario between today and 2050 would be approximately US$ 11.4 billion.

Because renewable energy has no fuel costs, however, the fuel cost savings in the basic Energy [R]evolution scenario reach a total of US$ 147 billion, or US$ 3.7 billion per year. The Advanced Energy [R]evolution has even higher fuel cost savings of US$ 191 billion, or US$ 4.8 billion per year.

These renewable energy sources would then go on to produce electricity without any further fuel costs beyond 2050, while the costs for coal and gas will continue to be a burden on national economies.
