AGL Energy Ltd is an Australian listed public company involved in both the generation and retailing of electricity and gas for residential and commercial use. AGL is Australia's largest electricity generator, and the nation's largest carbon emitter. In 2022, 83% of its energy came from burning coal. It produces more emissions as a single company than the nations of New Zealand, Portugal or Sweden, according to its largest shareholder, Mike Cannon-Brookes, who named it "one of the most toxic companies on the planet". AGL also generates a small percentage of energy from renewable sources. It is, however, targeting 12 gigawatts of new renewable energy by 2035. It closed Liddell Power Station in 2023, but aims to close Bayswater Power Station in 2033, and Loy Yang A Power Station in 2035. It is one of the "big three" retailers in the National Electricity Market. Wikipedia
