Life cycle assessment of geothermal well for hot water production

Since the study is concerned with a geothermal energy system, attention has been focused on the energy index and the energy consumption. The reliability of life cycle assessment is depends on complete data, that are not always available. The ISO14040 norm recommends the investigating of those parameters, that could influence the final environmental profile. Regarding of data quality, life cycle assessment studies should include time related coverage, geographical coverage, technology coverage; precision, completeness and representativeness of data consistency and reproducibility of methods used throughout the life cycle assessment, sources of the data and their representativeness to eliminate the uncertainty of the information.
