This report provides an overview of different types of capital flows and an analysis of the trends in sustainable energy investment activity in developed and developing countries.
The information is intended to be a strategic tool for understanding the status of the sustainable energy sector's development and for weighing future public and private commitments to the sector.

The purpose of this study is to gain a more differentiated picture of the impact of the global financial crisis on the renewable energy sector by determining changes and trends in investment flows for renewable energy technologies and companies as the cost of capital rises and access to credit becomes more difficult.
