History Of Electricity In Australia
Electricity has been a part of Australia's story since the late 19th century. While early settlers used candles and oil lamps for lighting, by the 1880s, gas was used in some cities. But it wasn't until 1885 that electricity began to be generated and used on a large scale in Australia.
The first electric street lights in Australia were installed in Sydney in 1879. The following year, Melbourne got its first taste of electricity with a public demonstration of an arc lamp. In 1885, a power station was built in Sydney, followed by the installation of electric street lights on a large scale.
The history of electricity in Australia goes back to the early days when Australians generated electricity using coal-fired power stations. But as Australia started to industrialise in the early 20th century, electricity demand increased, and they built new power stations, such as the Grenfell Street power station in South Australia, using hydroelectricity, which is water-generated.
Hydroelectricity in Australia
Rob Linn was an Australian engineer who played a pivotal role in the development of hydroelectricity in Australia. He designed the first hydroelectric power station in the country at Geeveston in Tasmania. The power station was completed in 1914 and supplied electricity to the town and surrounding area.
Hydroelectricity quickly became popular as it was a clean and renewable energy source. By the 1930s, nearly half of all electricity generated in Australia came from hydroelectric power stations. The Snowy Mountains Scheme is one of the world's largest and most ambitious hydroelectric schemes.
It was started in 1949 and took 25 years to complete. The scheme includes 16 major dams, seven power stations, and more than 80 tunnels, canals, and aqueducts. It supplies electricity to New South Wales, Victoria, and the Australian Capital Territory.
Early electricity demand in Australia
As Australia's population and economy have grown, so has the electricity demand. In the 1970s, Australia began to use coal-fired power stations on a large scale to meet this demand. But as the concern about climate change has grown in recent years, the use of renewable energy has increased.
The growth of renewable energy is helping Australia to reduce its emissions of greenhouse gases. In 2020, Australia expected renewable energy to provide 33% of all its electricity.
