Increasing energy efficiency; reducing energy demand, greenhouse gas emissions, and the use of waste; and integrating renewable and recycled heat from low-temperature sources are significant challenges today and are key parts of 4th Generation District Heating (4GDH) concept. On the other hand, currently about one billion people around the world are suffering from water scarcity, and another three billion are approaching this situation. Only 2.5% of all water on the planet is freshwater, of which around 70% is not available and only 0.4% constitutes the most valuable portion of freshwater. Adsorption cooling technology is one of the most effective ways of addressing both these issues. This technology cools and produces potable water from the renewable and wasted heat of the near ambient temperature, including from sewage water, solar heat, and underground resources. This Special Issue Reprint Book provides the detailed information concerning the above-mentioned issues.

Geothermal energy is a renewable, sustainable, and ecologically friendly resource of energy that can be captured with shallow or deep installations, or a combination of both—alone or integrated with other technologies. It can then be employed for a variety of purposes, for example, electricity generation, space heating and cooling, agriculture, and aquaculture. Given the nature/features of this green energy resource—such as being a local, climate-independent, potentially constant, robust, generally available, resilient, almost greenhouse gas-free, and long-lived energy source—geothermal solutions can and should make a more prominent contribution to the future global energy supply mix, in addition to helping lessen humanity’s environmental footprint and enabling it to attain its sustainable development goals. This Special Issue, “New Trends in Enhanced, Hybrid and Integrated Geothermal Systems”, addresses existing knowledge gaps and aids advance deployment of geothermal energy globally. It consists of eight peer-reviewed papers that cover a range of subjects and applications related to geothermal energy.

The ongoing digitalization of the energy sector, which will make a large amount of data available, should not be viewed as a passive ICT application for energy technology or a threat to thermodynamics and fluid dynamics, in the light of the competition triggered by data mining and machine learning techniques. These new technologies must be posed on solid bases for the representation of energy systems and fluid machinery. Therefore, mathematical modelling is still relevant and its importance cannot be underestimated. The aim of this Special Issue was to collect contributions about mathematical modelling of energy systems and fluid machinery in order to build and consolidate the base of this knowledge.
