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

electricity generation

A dynamically growing renewable energy market will compensate for the phasing out of nuclear energy and reduce the number of fossil fuel-fired power plants required for grid stabilisation. By 2050, 78% of the electricity produced in the OECD Pacific will come from renewable energy sources. ‘New’ renewables – mainly wind, solar thermal energy and PV – will contribute 68%.

The installed capacity of renewable energy technologies will grow from the current 62 GW to more than 600 GW in 2050, an increase by a factor of ten.

To achieve an economically attractive growth in renewable energy sources, a balanced and timely mobilisation of all technologies is of great importance. Figure 6.121 shows the comparative evolution of the different renewables over time. Up to 2020, hydro-power and wind will remain the main contributors. After 2020, the continuing growth of wind will be complemented by electricity from biomass, photovoltaic and solar thermal energy.
