Queensland grid · community impact

Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Redland Bay's 3,497 solar systems typically avoid around 21.67 tonnes of CO₂ every hour during peak generation.

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

Redland Bay sits in the top third of Queensland for solar uptake, ranking 115th in the state out of 449 postcodes in the Clean Energy Regulator dataset. 221 new systems were added in the past 12 months, with growth of 6% on the previous year — typical of a maturing market where most interested households have already installed.

The combined impact is substantial: Redland Bay's solar community avoids an estimated 34,615 tonnes of CO₂ every year — equivalent to taking 16,483 cars off the road or powering around 6,923 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.
