Numbers of 25-30% plus, in terms of global percentage energy/electricity generation from renewables are of course very welcome. The exciting thing for me is just how high we can get that number with two major shifts in technology. Firstly of course, given it is my area of focus, is energy storage, at all scales, utility, C&I and (aggregated) residential. Add to that an overall reduction in electricity demand through energy efficiency, and smarter use of energy, through demand response and smart grids (and homes), and suddenly the fossil fuel death spiral goes into overdrive. Happy days!
