Solar generators may produce the majority of the world’s power within 50 years, slashing the emissions of greenhouse gases that harm the environment, according to a projection by the International Energy Agency.

Photovoltaic and solar-thermal plants may meet most of the world’s demand for electricity by 2060 -- and half of all energy needs -- with wind, hydropower and biomass plants supplying much of the remaining generation, Cedric Philibert, senior analyst in the renewable energy division at the Paris-based agency, said in an Aug. 26 phone interview.
