This research, jointly undertaken by Finland’s LUT University and the Energy Watch Group, does not only add one more study about climate-benign future energy systems, but rigorously opens up a new perspective towards a shift to 100% renewable energy within the next two to three decades. A global transition to 100% renewable energy across all sectors – power, heat, transport and desalination before 2050 is feasible. Primary energy supply in the 100% renewable energy system will be covered by a mix of sources, with solar. PV generating 69%, followed by wind energy (18%), biomass and waste (6%), hydro (3%) and geothermal energy (2%) by 2050. Solar Wind energy and solar PV make up 96% of total electricity, and approximately 88% of the total energy supply, which will have a synergetic balancing effect.
A 100% renewable power system will employ 35 million people and solar PV emerges as the major job creating industry, employing more than 22 million by 2050, followed by battery, biomass, hydro and wind industries. Energy storage will meet nearly 23% of electricity demand and approximately 26% of heat demand. Batteries will emerge as the most relevant electricity storage technology and thermal energy storage emerges as the most relevant heat storage technology by 2050.
