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!
Among the key findings from the report is the current level of variable renewable energy currently in place. The report found that renewable energy, including hydropower, currently accounts for approximately 30% of the total global installed power generating capacity, as well as 23% of the total global electricity production. Specifically, over the last decade, wind and solar PV have seen a meteoric rise, representing 23% and 51% respectively in terms of average annual growth in installed capacity — although, to temper that somewhat, their combined contribution to the global electricity production is only around 4%.
