The Use of Geothermal Energy for Heating Buildings as an Option for Sustainable Urban Development in Slovakia

Abstract

The use of geothermal energy (GE) and the green economy in the environment of Slovak municipalities and towns is significant, due to the reduction in the negative influences and impacts of human society’s constant consumer lifestyle. The authors highlight the use of modern scientific knowledge, practical experience, and ever-improving technologies in the field of renewable energy sources RES. The aim of this contribution is to draw attention to the under-utilization of GE’s potential in Slovakia. Given the country’s commitment to meeting emission limits under EU carbon neutrality agreements by 2050, the use of this resource is very pertinent. Slovakia has significant geothermal resources that are not currently sufficiently utilized. The article suggests using GE to heat housing units of the housing estate near the geothermal source. Three scenarios (60 °C (pessimistic), 65 °C (conservative), and 70 °C (optimistic)) were considered in our energy balance and economic advantage calculations. The green economy offers a sustainable way of using the earth’s resources. The financial calculations regarding the amount of investment, the expected financial return and the possible values of the saved emissions confirm the possibility of the further use of GE technology. The information under consideration can be used in other significant territories, which may be a theme for further research in this field.

The Use of Cultural Landscape Fragmentation for Rural Tourism Development in the Zemplín Geopark, Slovakia

“…Practically speaking, all the works evaluating the regional structure of Slovakia based on social (socio-economic) development state that the Banská Bystrica Region (GDP per capita in PPS was 55% of the EU average in 2014), the Prešov Region (46% of the same), and the Košice Region (60% of the same) are the underdeveloped NUTS3 Slovak regions [119][120][121][122][123][124][125][126][127][128]. The most lagging region of Slovakia on the NUTS2 level is East Slovakia (53%) [129].…”

Sustainable Development Processes for Renewable Energy Technology

“…Se ňova et al [9] propose the use of geothermal resource in the conditions of central Europe, for the purpose of heat supply to the population, while calculating the energy balance, they consider three scenarios, depending on the temperature level of the output medium. The results show the economic and environmental justification for the use of low-to medium-temperature sources in the given conditions and in the current energyenvironmental and economic framework.…”

Energy Transformation and the UAE Green Economy: Trade Exchange and Relations with Three Seas Initiative Countries

“…In January 2022, the President of Slovakia paid a visit to Dubai for cooperation on the transition to a greener economy and hydrogen technologies. This is expected to revolutionize the private, public transport, and freight sectors [50]. In February 2022, within the third JEC, Hungary and UAE adopted a cooperation program, which covers, among others, trade, investment, water resource management, and renewable energy.…”
