3,329 solar installations registered with the Clean Energy Regulator · ranked top 50% in Australian Capital Territory · data current as at 2026-06-15
Based on last week's Australian Capital Territory grid mix (avg 790 gCO₂/kWh), Cook's 3,329 solar systems typically avoid around 20.12 tonnes of CO₂ every hour during peak generation.

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. 232 new systems were installed in the past 12 months, a 15% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Cook's solar community avoids an estimated 32,138 tonnes of CO₂ every year — equivalent to taking 15,304 cars off the road or powering around 6,428 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.
