Dr. Evans, UBC Engineering professor, will tackle the prospect of global climate change brought about primarily by our prolific energy use and heavy dependence on fossil fuels. Learn how all of our energy needs are supplied from just three primary energy sources, why some proposed solutions are more sustainable than others and how the link between energy consumption and greenhouse gas emissions can be broken. (A special Alumni Weekend 2007 presentation sponsored by UBC Alumni Affairs, originally presented on 15-Sep-2007)
