IEA Sees $45 Trillion Investment for World Energy
The world needs to invest $45 trillion in energy in coming decades, build some 1,400 nuclear power plants and vastly expand wind power in order to halve greenhouse gas emissions by 2050, according to the International Energy Agency.
The IEA envisions an “energy revolution” that would greatly reduce the world’s dependence on fossil fuels while maintaining steady economic growth.
A U.N.-network of scientists concluded last year that emissions have to be cut by at least half by 2050 to avoid an increase in world temperatures that could result in widespread loss of species, famines and droughts, and swamping of heavily populated coastal areas by rising oceans.
