This report is considered by many to be the most authoritative appraisal of clean energy investment trend. It comes less than six months before the crucial UN climate convention meeting taking place in Copenhagen, Denmark.

Renewable energy, with its low carbon footprint, the relative speed with which it can be deployed into developed and developing communities alike and its ability to generate new kinds of businesses and green jobs, is a key element of that transition.
