Cook sits in the top third of Australian Capital Territory for solar uptake, ranking 8th in the state out of 28 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 256 new systems installed in the past 12 months — a 32% increase on the previous year, making Cook one of Australian Capital Territory's faster-growing solar postcodes.
The combined impact is substantial: Cook's solar community avoids an estimated 32,785 tonnes of CO₂ every year — equivalent to taking 15,612 cars off the road or powering around 6,557 average Australian homes with clean electricity. This is estimated using Australian Capital Territory's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
