The development of the electricity supply market is charaterised by a dynamically growing renewable energy market and an increasing share of renewable electricity. This 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, 97% of the electricity produced in OECD North America will come from renewable energy sources. ‘New’ renewables – mainly wind, solar thermal energy and PV – will contribute 84% of electricity generation. The Energy [R]evolution scenario projects an immediate market development with higher annual growth rates achieving a renewable electricity share of 42% by 2020 and 75% by 2030. The installed capacity of renewables will reach 1,721 GW in 2030 and 2,780 GW by 2050.
Table 5.7 shows the comparative evolution of the different renewable technologies in OECD North America over time. Up to 2020 hydro and wind will remain the main contributors of the growing market share. After 2020, the continuing growth of wind will be complemented by elelctricty mainly from photovoltaics, solar thermal (CSP), and geothermal energy. The Energy [R]evolution scenario will lead to a high share of fluctuating power generation source (photovoltaic, wind and ocean) of 43% by 2030, therefore the expansion of smart grids, demand side management (DSM) and storage capacity from the increased share of electric vehicles will be used for a better grid integration and power generation management.
