Developing a sustainable supply and consumption of energy is determined by many different factors. We must not only find economically and environmentally beneficial solutions for society. These solutions must also be adapted to all levels from everyday life in households to the engineering of new technological systems. It has significance for our way of living together, for example

• New types of energy plants may conflict with the interests of local residents and businesses
• When private households invest in, for example, solar cells or small wind turbines, they acquire a new role and become part of the energy supply, which in turn has consequences for their economy as well as their everyday life.
• Reduced energy consumption is not just about designing buildings and appliances, but also about how people keep their homes, transport themselves, communicate and in general live their lives.
