Energy in Saudi Arabia

Energy in Saudi Arabia involves petroleum and natural gas production, consumption, and exports, and electricity production. Saudi Arabia is the world's leading oil producer and exporter. Saudi Arabia's economy is petroleum-based; oil accounts for 90% of the country's exports and nearly 75% of government revenue. The oil industry produces about 45% of Saudi Arabia's gross domestic product, against 40% from the private sector. Saudi Arabia has per capita GDP of $20,700. The economy is still very dependent on oil despite diversification, in particular in the petrochemical sector.

For many years the Kingdom of Saudi Arabia has been the world's largest petroleum producer and exporter. In 2011 it pumped about 1.7142 million m³ (10.782 million bbl) per day of petroleum. While most of this is exported, domestic use is rapidly increasing, primarily for electricity production. Saudi Arabia also has the largest, or one of the largest, proven crude oil reserves (i.e. oil that is economically recoverable) in the world (18% of global reserves, over 41 billion m³ (260 billion bbl)).

Saudi Arabia has one of the largest reserves of natural gas in the Persian Gulf. Proven natural gas reserves are over 7 trillion m³ (44 trillion bbl). Global production in 2009 reached 4.6 billion m³ (29 billion bbl) of oil and 3 trillion cubic metres (110 trillion cubic feet) of natural gas. but due to its sizeable domestic gas markets, is "unlikely to become LNG exporters anytime soon". Saudi Arabia is prioritising upstream gas investment, but for use in the domestic power generation market, not for export.

The country has had plans to diversify its energy sources for some time, developing solar and nuclear power.
