The world is enjoying a "green energy gold rush", the UN's environmental agency said Tuesday as it published a report outlining a 60 percent hike in investment in renewable energy in 2007.
The UN Environment Programme (UNEP) study, published in Nairobi, said more than 148 billion dollars (93 billion euros) of new funds were ploughed into the quest for cleaner energy last year.
"Just as thousands were drawn to California and the Klondike in the late 1800s, the green energy gold rush is attracting legions of modern-day prospectors in all parts of the globe," UNEP Executive Director Achim Steiner said in a statement.
"What is unfolding is nothing less than a fundamental transformation of the world's energy infrastructure."
