It's clear that we are going to see this number increase at a rapid rate, and not just in emerging economies. Without the generous tax breaks provided to the oil and gas industry solar is clearly going to win out as the cheapest form of new energy supply in the majority of the established economies too. Microgrids are going to be significant especially in the emerging economies. Solar combined with energy storage can provide a reliable, clean power supply to many areas that do not have access to the main electricity grid. Long live solar!!
