Thanks to PV systems and battery storage, millions of households in Europe are already partially self-sufficient.
“Under today’s conditions, 53% of the 41 million buildings are technically capable of powering themselves through the use of local rooftop PV systems alone, independent of external infrastructure, and this share could rise to 75% by 2050 due to improved technologies,” said researcher Russell McKenna. “If we now assume that building owners would be willing to invest up to 50% more than would be necessary for a comparable energy system with a grid connection, then up to two million single-family homes could leave the grid by 2050.”
The research group was formed by scientists from the Karlsruhe Institute of Technology (KIT) and the Forschungszentrum Jülich GmbH, as well as the Swiss Federal Institute of Technology Zurich (ETH Zurich) and the Paul Scherrer Institute.
