Summary: James caught up with Dr Mark Diesendorf from the Institute of Environment Studies, University of NSW and Author of the Book ' something' about de-carbonising our electricity system. Diesendorf tells us from now until 2020, energy efficiency measures and solar hot water can reduce our demand by around 50%. This can be coupled with wind and biomass energy. After 2020 Mark suggests solar thermal and pv, as well as geothermal can potentially supply all our energy needs. He also calls for a moratorium on new coal fired power.
