Australia's rapid expansion of solar and wind energy has not increased wholesale electricity prices since 2016, making it a global renewable energy leader. Solar and wind are displacing coal and gas, meeting all growth in demand, with stable grid infrastructure and high rooftop solar adoption rates contributing to falling wholesale prices. Rooftop solar systems in Australia cost $6,000 and last 20 years, with an annual electricity output of 1200-1400 kWh per kW, driving widespread adoption at a low cost of 3 US-cents per kWh. All-electric solar homes in Australia have zero gas and petrol bills, with large energy storage options available, and the quick installation and high resilience of Australian rooftop solar systems make them a promising solution for climate experts.
