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

5.8 consumption of primary energy

Figure 5.9 shows the consumption of primary energy resulting from the Energy [R]evolution scenario. In this scenario, global demand for primary energy will rise 49% over current levels, from 11,347 PJ to 16,930 PJ per year in 2050.The total is 27% lower than the reference scenario, which will reach 23,060 PJ in 2050.

In the Energy [R]evolution scenario renewable energies will achieve a 50% share in 2030 and 67% in 2050. In this projection, almost the entire supply of electrical energy, including most of the energy used in buildings and industry, will come from renewable energy sources. The transportation sector, in particular air and sea modes, would be the last sector to reduce the use of fossil fuels.
