Brunei generates electricity solely through natural gas generators because natural gas is cheap, less polluting, and Brunei has its own oil and gas resources. It does not use any renewable energy generators. Brunei consumes 52 billion kWh of electricity annually, the third highest usage in Southeast Asia behind Indonesia and Malaysia. Bruneians waste electricity due to double subsidies that cause them to undervalue and underappreciate electricity, as well as pay much less for usage compared to other countries. Earth Hour is held annually to raise awareness about climate change by encouraging people to switch off appliances for one hour.
