Casuarina is one of Northern Territory's strongest solar communities, ranking 1st in the state — ahead of 98% of all Northern Territory postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 204 new systems installed in the past 12 months — a 42% increase on the previous year, making Casuarina one of Northern Territory's faster-growing solar postcodes.
The combined impact is substantial: Casuarina's solar community avoids an estimated 34,592 tonnes of CO₂ every year — equivalent to taking 16,472 cars off the road or powering around 6,918 average Australian homes with clean electricity. This is estimated using Northern Territory's average grid emissions intensity of 640 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
