100-percent renewable German energy system possible – study
Powering a large country like Germany entirely with renewable energy is possible, and could even be cheaper than conventional energy sources, according to a study by the Karlsruhe Institute of Technology (KIT). Technical solutions for all of the well-known problems that come with “a full energy transition” already exist, says co-author and physicist Tom Brown in a KIT press release. Blackouts are not a problem either, Brown says, as renewables could be used to create hydrogen or methane gas reserves stored for emergencies or times of low output from wind and solar power plants.
