Queensland grid · community impact

Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Forest Lake's 6,041 solar systems typically avoid around 37.43 tonnes of CO₂ every hour during peak generation.

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

Forest Lake sits in the top third of Queensland for solar uptake, ranking 62nd in the state out of 449 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (270 systems, 22% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Forest Lake's solar community avoids an estimated 59,796 tonnes of CO₂ every year — equivalent to taking 28,474 cars off the road or powering around 11,959 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.
