By 2020, will be installed new capacity of green energy of 700 gigawatts or the equivalent of 700 nuclear reactors, which will represent almost two thirds of the new capacity of the electrical system worldwide added up to that date, detailed the IEA, headquartered Paris, in its medium-term renewable energy report, released Friday.
Developing renewable energy will be particularly important in developing countries. Only China will hold only 40% of new capacity installed.
This was especially the case in South Africa, Brazil, India, Middle East and some US states.
This estimate of funds arising from 'the decline of installing new capacity, but also in reducing the cost of investment and the most dynamic technologies', including solar and wind land, the agency said.
And lowering the cost of these forms of energy, already observed in recent years should continue, AFP notes.
AIE is proving more cautious on energy based on biofuels, an increase that will continue despite lower oil prices, but at a rate stabilized. This will represent 4% of the demand for fuel in road transport in 2020.
The successful development of renewable energy and thus combating climate change requires "reduce regulatory uncertainty" which prevent most significant deployment, "the IEA warned.
While land-based wind power and solar PV 'do not need high levels of support (public)', their attractiveness 'will depend largely on the regulatory framework and market functioning', sais the Agency.
