As an independent consultant based in Eugene, Oregon, David works and has worked for many agencies, including ADB, the United Nations, the World Bank, Nautilus Institute, USAID, and many others on a broad range of energy and environmental topics in dozens of countries. Many of the projects completed during David’s 35-plus years in the field have involved analysis of renewable and other energy systems for electricity generation and meeting other energy needs. Development and evaluation of economy-wide future energy scenarios and integration of climate change issues in energy systems planning, and capacity building in same, has been a major focus.
