N2 - Power generation is a source of environmental pollutants globally. In Kenya, energy sources are mainly renewable. A life cycle assessment (LCA) of geothermal energy is presented for five geothermal power plants calculated using a geothermal LCA calculator developed by Argonne National Laboratory. The metrics calculated for electricity generation were greenhouse gas ratios, fossil energy, and material to power ratio (MPR). MPR values for different materials consumed were cement between 73-417 MT/MW and steel between 102-464 MT/MW. Energy input in development contributed mainly to greenhouse gas emissions of between 1.115-3.189 g/kWh. LCA in prospecting fields reduces the environmental impacts and aims at a higher drilling success rate.
