Toowong sits in the top third of Queensland for solar uptake, ranking 97th in the state out of 449 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 266 new systems installed in the past 12 months — a 29% increase on the previous year, making Toowong one of Queensland's faster-growing solar postcodes.
The combined impact is substantial: Toowong's solar community avoids an estimated 40,336 tonnes of CO₂ every year — equivalent to taking 19,208 cars off the road or powering around 8,067 average Australian homes with clean electricity. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
