Gumdale ranks 228th in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. Growth has been strong, with 54 new systems installed in the past 12 months — a 26% increase on the previous year, making Gumdale one of Queensland's faster-growing solar postcodes.
Collectively, Gumdale's 945 solar systems avoid an estimated 9,354 tonnes of CO₂ per year — the equivalent of removing 4,454 cars from the road. 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.
