An attempt to measure the efficiency of Arab countries in energy consumption using the data envelope analysis method

Abstract

The study aimed to measure the efficiency of 14 Arab countries in energy consumption for the period (2015-2019) using the data envelope analysis method with input guidance, the variable returns to scale (BCC-I), based on Electricity consumption per capita (in kilowatt-hours) as inputs, GDP per capita (in current US$) and CO2 emissions per capita (in metric tons) as outputs.
The study concluded that the Arab countries under study achieved an average efficiency for the period (2015-2019) of (0,823), and that there is a discrepancy between the efficiency rates of these countries, as 03 countries achieved averages of complete efficiency (1,000), and 05 countries averaged efficiency between (0,900) and (1,000), while the rest of the countries achieved averages of efficiency less than (0,900), In addition, making the required improvements for the year 2019 could contribute to improving efficiency in energy consumption by reducing the average electricity consumption per capita from 7.094,27 kWh to 5.396,05 kWh, and reduce the average CO2 emissions per capita from 11,20 to 10,37 metric tons, therefore, public policy makers in Arab countries should take more effective decisions and actions to improve energy efficiency
