Christmas Hills ranks 292nd in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (32 systems, 16% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Christmas Hills's 730 solar systems avoid an estimated 8,742 tonnes of CO₂ per year — the equivalent of removing 4,163 cars from the road. This is estimated using Victoria's average grid emissions intensity of 980 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
