The Earth is under increasing stress owing to carbon emissions. Clean energy\nforms constitute an area of increasing technological interest. Geothermal\nenergy is a clean alternative energy form that can be harnessed from the\nEarthâ??s core. The use of geothermal energy resources is gaining substantial\ninterest in many countries, as an integral part of 21st century clean energy solutions\nand meeting stringent emission requirements. The objective of this\nresearch is to investigate an alternative approach to clean and renewable geothermal\nenergy utilization through geothermal ground water pressure applied\nwithin a water turbine. The groundwater pressure from the candidate geothermal\nsites considered is applied to drive a water turbine for the generation\nof electrical energy. The geothermal candidate sites are low-temperature (i.e .\n<60DegreeC) geothermal springs, where it is not beneficial to apply low temperatures\nin a Rankine cycle steam turbine due to the low enthalpy. Simple calculations\nare conducted to estimate the electrical energy output of each candidate\nsite. This may technically be regarded as a thermodynamic problem, albeit\none that does not require full thermodynamic cycle analysis. The results\nof the simple non-rigorous analysis indicate that the electrical energy generation\npotential is greater when using geothermal water pressure (2.5 MWe)\nthan when using low geothermal temperature (0.005 MWe).
