Greetings from the Australian National University in Canberra, where William ("Bill") Tumas from the US National Renewable Energy Laboratory is speaking on "Solar Energy R&D and Materials by Design". Dr. Tumas argued that further advances in photo-voltaic (solar) energy were possible to go beyond grid parity, that is not just make solar power as cheap as coal generated electricity, but make it much cheaper. He used the analogy of the development of the automobile: early cars were used as replacement for horse drawn carriages, but the performance of cars did not end with "horse parity". Dr. Tumas also pointed out that much of the cost of PV power is now not the cost of the PV material, but installation of the panels.
