Electricity consumption per capita has been gradually increasing by 8% annually during the past 10 years in the Kingdom of Saudi Arabia. One of the main reasons for this above-average growth rate is the utilization of low efficiency electrical home appliances, which is encouraged by the low initial investment and the artificially low energy prices. In 2013, the residential sector consumed nearly 126 terawatt hours, which represents 49% of the country's electricity consumption. This paper investigates the potential savings in primary energy that can be achieved by switching residential water heating and cooking appliances from electricity to liquefied petroleum gas (LPG). Taking advantage of the much higher source-to-site energy conversion efficiency for LPG versus electricity and the abundance of low price LPG in Saudi Arabia, this paper presents compelling evidence of the overall benefits to the Kingdom in terms of primary energy savings and CO2 emissions reductions. This paper also proposes solutions for current inhibiting factors such as the need for enabling policy and LPG safety standards, as well as consumer awareness.
