Utilization of Geothermal Energy is supportive of the ongoing changes in cities and their planning, which involve proposals for thermal and power grids and solar architecture. One way of supporting GE utilization in cities is through investing in energy efficiency and turning to passive design in urban planning. This combination is especially important for many cities worldwide which are facing urban sprawling and transport issues. Sustainable development of cities and towns in Europe and in USA could be supported by investing into GE infrastructure in the long run. This can contribute to a more alleviated urban development of urban and rural environments in the region. The value of centralized GSHP for mixed-use neighborhood planning is especially notable for further research on GE utilization in cities. Changes in demography (coming of age of the millennial generation) can initiate a broader use of GE, as well as pilot projects, which demonstrate that GE does exist in a city. Research on cultural factors that could influence a single end-consumer to turn to GE is recommended as they represent key factors for the future of GE utilization in cities.weiterlesen
