Rosemary Grundy has done a detailed analysis of how long it will take to get a return on her investment in renewables. From the day she moved into her new house in December 2021, she’s diligently recorded how much she saves from not using fossil fuels, and how much she pays for electricity, and calculated that she’ll break even on her solar panels, batteries, and two electric vehicles in just under 9 years. Rosemary is now developing a break-even calculator to help other householders work out when they’ll break even on their renewable investments, and is on a mission to show Australians who have the financial capacity, that making the transition to renewables is not only good for the climate, it makes financial sense.
