To reduce your reliance on the main power grid (which is mostly powered by fossil fuels), install a fully renewable power source such as solar or wind power. By using green energy, a household or business will reduce its environmental footprint and cut electricity costs over time. As at January 2024, over 3.7 million solar PV systems had been installed across Australia (see latest data here).

You can also consider using rechargeable solar batteries and battery storage systems, especially if you have a hybrid or electric vehicle. Do your research first (see links below), as the systems and technologies continue to evolve.

If you manage a business, look at the business case of installing a solar system. To measure return on investment, determine the lifetime cost of a solar installation and energy generated compared to your electricity provider. Consider any tax and depreciation incentives for solar equipment when calculating financial returns.
