China is now the biggest investor in large-scale renewable projects, through wind farms in particular, while Germany leads the world in new investments in small-scale solar panels on rooftops.

However, the investment activity in developing countries increased strongly worldwide:
• South and Central America: up 39% to $13.1 billion;
• Middle East and Africa: up 104% to $5 billion;
• India: up 25% to $3.8 billion;
• Asian developing countries excluding China and India: up 31% to $4 billion.

For the first time developing countries have overtaken developed countries in terms of "financial new investment".

The authors have forecast that "Further improvements in the cost of energy for solar, wind and other technologies lie ahead, posing a bigger and bigger threat to the dominance of fossil-fuel generation sources in the next few years."
