Environmental Impact Comparison of Geothermal Alternatives for Conventional Boiler Replacement

In the transition towards a sustainable world with “green horizon” (something that is also of great importance to policy energy self-sufficiency in housing and self-consumption), geothermal seen as quite feasible alternative for single-family homes. This article focuses on comparison between environmental impact life cycle analysis three alternatives provides base case replacement conventional type boiler one typical house located Mediterranean climate. The first (A) consists horizontal catchment system through field probes. second (B) shallow water system, open type, return nearby river. third option studied (C) but water, injected into well downstream underground flow. study shows A B have least most categories studied. total amortization periods differ by almost two years, taking 6.99 years C costing 8.82 years.
