Renewable energy is crucial for the present and the future since the ultimate objective of the sustainable energy system is to maintain our current needs without sacrificing the needs of future generations. In contrast to fossil fuels, which have a finite supply, solar energy is a renewable energy source that is sustainable.

The availability of renewable energy sources including solar, wind, geothermal, hydro, and biomass energy is expanding quickly because of technical developments that have lowered costs and enhanced efficiency. Solar energy use has accelerated recently, particularly when discussing sustainability.

Hydropower is essential as we transition toward a Net Zero future. As the largest renewable energy source worldwide, and the third largest energy source overall after coal and natural gas, hydropower has a crucial role to play.

In September 2022, Australia announced its Climate Change Bill, setting targets to reduce greenhouse gas (GHG) emissions by 43% by 2030, as compared to 2005, and to become net zero by 2050.
