Jordan's economy is among the smallest economies in the Middle East. The insufficient supply of water, oil, and other resources, underline the heavy reliance of the government on foreign assistance. In 2013, Jordan’s average annual population growth rate was around 2.5%, with total population 6.46 million. Its CO2 emissions were 22.82 Mt representing 1.4% of total Middle East emissions. Total primary energy supply in 2013 was 7727 thousand tons of oil equivalent (ktoe), with 83% coming from oil, 3% coal, 2% renewables and 12% from natural gas. Electricity generation capacity is expected to reach 4000 MW by 2020 with an average 300 MW per year. Between 2008 and 2020, the country’s total electricity demand is projected to increase by 7.4% annually implying further increase in energy imports.
