The world can shift to 100% renewable electricity sources by 2050 using today's technology and be more cost effective than the present fossil-fuel based system, according to research from Finland’s Lappeenranta University of Technology and Energy Watch Group. A new study published in Nature Climate Change shows that a transition away from fossil fuels is possible with current technology. Solar PV would cover 69% of electricity supply, wind 18%, hydro 8% and bioenergy 2%. More investments need to be channeled in renewable energies and the necessary infrastructure for storage and grids. About 31% of demand would be met by energy storage, of which 95% would be from batteries and the remainder from power-to-gas technology.
