Heat Pump Technology: Essential for Achieving Carbon NeutralityHeat generated by burning fossil fuels produces greenhouse gases, which are the primary cause of global warming. Heat pump technology uses electricity to generate heat that is several times greater than the amount of electricity consumed. When powered by renewable energy, it does not impose a burden on the global environment.This book clearly outlines the future society enabled by heat pump technology, as well as the roadmap and policies necessary for its realization.We encourage everyone concerned about the global environment to read this book.Dr. Hiroshi Komiyama, The Chairman of the Mitsubishi Research Institute / The Chairman of the Platinum Society Network / The 28th President of the University of Tokyo.
