Ethiopia has an estimated >10,000 MW of geothermal energy potential, more than double its current power generating capacity (4,400 MW). Electricity access stands at 44% the total population, with 31% in rural areas, so effective development this low-carbon resource could make a significant impact to equitable delivery electricity. However, exploitation must be done responsibly protect valuable ...

introduction suitability of groundwater for drinking, irrigation and industrial purposes depends upon its quality. changes in groundwater quality are due to variation in climatic conditions, residence time of water with aquifer materials and inputs from soil during percolation of water. multivariate statistical methods are one of the common and important methods for hydro geochemistry study. sa...
