Queensland grid · community impact

Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Postcode 4740's 18,414 solar systems typically avoid around 114.10 tonnes of CO₂ every hour during peak generation.

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

Postcode 4740 is one of Queensland's strongest solar communities, ranking 4th in the state — ahead of 99% of all Queensland postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (1,360 systems, 28% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Postcode 4740's solar community avoids an estimated 182,268 tonnes of CO₂ every year — equivalent to taking 86,794 cars off the road or powering around 36,454 average Australian homes with clean electricity. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
