摘要：It is important to know the structure of electricity production of a country and to establish the place of each source within the total energy mix. The aim of this paper is to analyze statistically the percentage of the hydropower production related to the total electrical energy produced in Romania. The time series data analysis was done to determine the trends of average and standard deviation of hydro energy data produced in Romania over eleven years' period (2006-2016).
