DOHA, Qatar — The world's top scientific body concluded that renewable energy in the coming decades will be widespread and could one day represent the dominant source for powering factories and lighting homes, according to a draft report obtained by The Associated Press Thursday.
But the report also warned that such expansion will be costly and policy changes will have to be enacted to ensure that renewable energy can achieve its potential in helping reduce greenhouse gas emissions.
It called for better balancing competing demands for land, addressing "institutional barriers" that prevent the installation of solar energy as well as overcoming the constraints to transmitting renewable energy to users.
.......... And despite its rosy predictions for renewable use, at least one environmental group observing the talks say the report falls short of their expectations.
"IPCC delivers a landmark report that shows the rapid growth potential for renewable energy — but unfortunately does not endorse a 100 per cent renewable energy pathway until 2050," said Stephan Singer, director for Global Energy Policy at WWF International.
"We need to be fast if we want to tackle pressing issues as varied as energy security and efficiency, and at the same time keep climate change below the danger threshold," he added.
