Readers of this blog may be interested in a new blog by my ERG colleague Dan Kammen. Dan is currently on leave from Berkeley to head the Clean Tech effort at the World Bank as the Bank’s Chief Technical Specialist for Renewable Energy and Energy Efficiency. Recent subjects range from cook stoves in Africa to renewable energy in Malaysia and climate impacts on your local energy supply. Before going to the Bank, was the co-developer of the Property Assessed Clean Energy [PACE] Financing Model, an energy efficiency and solar energy financing plan that allows installation of clean energy systems on residences with no up-front costs. PACE was named by Scientific American as the #1 World Changing Idea of 2009.
