Green energies like wind and solar power could play a major role in improving the lives of millions of the world's poorest people, says a report to be handed to world leaders at a summit in Genoa, Italy next weekend. The report, co-written by Mark Moody-Stuart, the chairman Anglo-Dutch oil giant Royal Dutch/Shell, says the G8 countries should aim to ensure renewable energies reach one billion people by the end of the decade, according to a draft seen by Reuters on Friday.
