Sunny Prospects–Examples of Sustainable Energy Supply

A life beyond fossil and nuclear energy sources is already possible today. This chapter illustrates this based on impressive examples from different areas. It is technically as well as economically easy to incorporate energy supplies that are low or neutral in carbon dioxide into new buildings in particular. Building renovations or the installation of a new heating system present the ideal opportunity to make enormous reductions in carbon dioxide. Plug‐in hybrid vehicles are normally recharged through a power point and for emergencies have a combustion engine that can run on biofuel. Pure electric cars only run on electricity. As a result of globalization, goods are shipped over ever‐longer distances. A large part of the increase in transport is being handled by commercial shipping. The carbon dioxide emissions per transport kilometre are lower for shipping compared to air freight. Solar boats offer climate‐compatible travel on water even if there is no wind, especially for short distances.
