在重新考虑未来的能源供应时，利用浅层地下热能发电、冷却和储存热能正变得越来越重要。浅层地热能的使用往往被宣传为在运行期间成本很低或没有成本，同时又对环境友好。因此，安装的系统数量在过去几十年里迅速上升，特别是在新建房屋中。虽然这种方法的二氧化碳减排潜力仍然是毋庸置疑的，但人们对这种方法的可持续性以及强化使用对土壤和地下水的潜在负面影响的担忧--甚至早在25年前就已经提出。然而，主要由于缺乏对系统的了解和工艺知识，仍然缺乏对浅层地下强化热利用的一致的管制和管理计划。与此同时，整个欧洲都在开发大型地热应用，例如完全依赖浅层地热能源使用或低潜热含水层储热的居民区。由于对浅层地下的密集热利用，以及潜在系统相互作用的程度，对土壤和地下水的潜在负面影响仍然未知。
Thermal use of the shallow subsurface for heat generation, cooling, and thermal energy storage is increasingly gaining importance in reconsideration of future energy supplies. Shallow geothermal energy use is often promoted as being of little or no costs during operation, while simultaneously being environmentally friendly. Hence, the number of installed systems has rapidly risen over the last few decades, especially among newly built houses. While the carbon dioxide reduction potential of this method remains undoubted, concerns about sustainability and potential negative effects on the soil and groundwater due to an intensified use have been raised—even as far back as 25 years ago. Nevertheless, consistent regulation and management schemes for the intensified thermal use of the shallow subsurface are still missing—mainly due to a lack of system understanding and process knowledge. In the meantime, large geothermal applications, for example, residential neighborhoods that are entirely dependent up on shallow geothermal energy use or low enthalpy aquifer heat storage, have been developed throughout Europe. Potential negative effects on the soil and groundwater due to an intensive thermal use of the shallow subsurface as well as the extent of potential system interaction still remain unknown.
