General View on Synergies and Trade-Offs Using Wastewater and Anaerobic Processes for Current in the Form of Biomass, CH4 and H2 as Well as Energy Production Systems

More than ever before in human history, climate change, which is largely caused by humans, will pose serious existential challenges for the first time. In particular, the future energy supply of mankind will play a decisive role. Fossil fuels can no longer be a future option unless the risk of further excessive use is ignored and accepted. There are sufficient alternatives available to replace fossil fuels. Renewable energies, including biomass, can replace almost 100 % of fossil fuels in an intelligent mix of wind, solar, tidal, and geothermal energy. In addition, efficient and optimised interaction is possible when combined with artificial intelligence. This chapter focuses on the use of biological processes and their contribution to future energy management and highlights synergies and trade-offs. The aim is to make it clear that with the help of these technologies, mankind can certainly keep the complex Earth system from becoming completely out of balance.
