(1) First and foremost, we need an immediate fossil fuel phase-out. Digital policies, new digital research fields and economic interests should not obscure this political necessity. Similarly, nuclear energy is not a clean energy source and no alternative to fossil-based energy production. A sustainable digitalization can only be based on efficient, clean, fair, accessible, decentralized renewable energies.
(2) National, regional and global strategies and effective legislation to decrease the energy use of IT and communication technology are urgently needed. This includes ecodesign policies and comprehensive energy efficiency labeling. Future regulation should prohibit glued-in batteries or accumulators in electronic devises in order to ensure users to freely and autonomously replace them.
(3) The interlinkage between decentralized renewable energies and decentralized internet infrastructure has to be supported and expanded.
(4) Big IT-companies carry a social, ecological and economical responsibility to fight climate change. IT-companies have to move to 100% renewable energy in the next years, improve their energy efficiency and transparently disclose the source of their energy supply.
