Why volatile energy prices make now the right time to go green

‍Like many Australians, you've probably felt it — at the pump, on your electricity bill, and in general, unease about where energy costs are heading. Global energy markets are inherently volatile. When supply chains are disrupted — wherever that happens in the world — it's ordinary households that end up absorbing the shock.

It's a frustrating pattern. But it's also a clarifying one.

The case for energy independence just got stronger

Every time global energy prices spike, the same truth becomes harder to ignore: a solar panel on your roof doesn't care what crude oil is trading at. A battery in your garage generates power regardless of what's happening to gas supply chains on the other side of the world. The households best insulated from these shocks are the ones who've taken steps to generate their own energy.

Australia has already made remarkable progress — over 40% of our electricity now comes from renewables, more than double the share a decade ago. But individual households can take that further. And the financial case for doing so has never been stronger.

Renewable energy at home isn't just good for the planet. Right now, it's one of the smartest financial decisions you can make. ‍

What the numbers look like

Green home loans offer a rate discount of 0.24% compared to average standard variable rates. On a $1.2 million loan, that difference adds up.

Refinancing to a Green Home Loan on a $1.2 million mortgage could save you around $2,200 per year in interest — and over $66,000 across the life of a 30-year loan.

Add to that the federal battery rebate — currently offering around 30% off the cost of an eligible home battery, though reducing from 1 May 2026 — and the combination of lower energy bills, a reduced upfront cost, and a discounted mortgage rate makes for a compelling picture.
