Grid intensity data: Open Electricity (openelectricity.org.au) · 7-day average · updates monthly

Howlong ranks 325th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (34 systems, 39% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Howlong's 892 solar systems avoid an estimated 8,611 tonnes of CO₂ per year — the equivalent of removing 4,100 cars from the road. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
