Hawthorn East ranks 280th 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 (50 systems, 37% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Hawthorn East's 784 solar systems avoid an estimated 9,389 tonnes of CO₂ per year — the equivalent of removing 4,471 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.
