Geothermal Energy with Heat Pump as a Possible Solution in Dramatic Climate Change – Market Situation and Potential in Germany of a Renewable Energy Source

Abstract

Goal: Global sustainability is becoming an increasingly important topic, which is impressively demonstrated by numerous conferences of the UN and its sister organizations with worldwide participation. The purpose of this paper is to critically review the use of geothermal energy through the use of heat pumps. Opportunities and starting points are discussed briefly. Design / Methodology / Approach: This paper does not only deal with geothermal energy, but also shows the potential uses and effects of using heat pumps. Not only the basic assumptions and the goals are documented, but these are, as far as possible, checked for their realism or feasibility. Carry out a method comparison of the published literature with technical, economic and ecological approaches. Findings: The findings are presented in a concise summary and provide opportunities for further analysis, discussion or results. The use of heat pumps is to reduce CO2 emissions in heat production, to measure the impact on nature using indicators and values. Geothermal energy can make a significant contribution to environmental protection through the use of heat pumps. Their lack of market penetration in Germany is apparently not due to too low benefits, but rather to lack of awareness (lack of marketing) and also lack of German government support, e.g. about tax incentives. Research / Practical Implications: Results and implications for practice, applications and consequences are identified. Use of geothermal energy and its effects can be assessed in the short, medium and long term. All people worldwide could use geothermal energy if they had a working electrical connection. Future research into renewable energy sources should always include geothermal energy, although currently it does not have enough multipliers and interest groups to support it. From the perspective of permanent availability (24/7), it is unbeatable. Originality / Value: This paper deals with sustainability and the related consequences in the field of regenerative energy production through the use of geothermal heat, as well as the implementation by means of heat pumps. In addition to purely scientific literature, facts and figures are used by the German Federal Environment Agency and the German Federal Ministry of Economics and Technology, which ensure the highest degree of neutrality.
