The hidden energy guzzler in 1.3 million Australian backyards - and how it could help the grid

Why apartments could be at the forefront of renewable energy adoption, rather than an afterthought

Australia's rooftop solar and battery boom has largely bypassed the millions of people who live in apartments, creating a growing energy divide between homeowners and everyone else. Allume Energy co-founder and CEO Cameron Knox explains the technical, legal and governance barriers that have kept apartment residents locked out of clean energy, and the innovations now helping to overcome them. He discusses how multiple apartments can share electricity from a single rooftop solar system, and how a new generation of battery-sharing technology could dramatically expand access to affordable renewable energy. Cameron argues that rather than being left behind in the energy transition, apartments have the potential to be at the forefront of residential renewable energy generation.

The hidden energy guzzler in 1.3 million Australian backyards - and how it could help the grid

Swimming pools don’t usually feature in discussions about household electrification, yet Australia's 1.3 million pool pumps consume a surprisingly large amount of electricity and can make up nearly 20% of a household’s electricity bill. Together Energy co-founder Patrick Michel discusses why pool pumps have been an overlooked energy efficiency opportunity and how pool chemistry has long prevented efforts to reduce run-times. He argues that with a bit of help from technology, smart scheduling and pool management can cut pump operating hours by 25 to 50 per cent without compromising water quality. Can Australia’s backyard pools become a new consumer energy resource, helping support a cleaner and more flexible electricity grid whilst saving households hundreds of dollars a year?

How I electrified: Why energy efficiency came first

A cold, draughty Melbourne terrace became the focus of a 25-year effort to improve comfort, cut emissions and reduce energy bills through a series of carefully planned upgrades. Starting with insulation, double glazing and draught-proofing long before electrification entered the mainstream, Anna Molan and Michael Fogarty's journey reflects the changing realities of Australia's energy transition. Their experience shows why an efficiency-first approach can make homes healthier, quieter and far more comfortable while reducing reliance on fossil fuels. Along the way they navigated solar, heat pumps, induction cooking, batteries and the practical challenges of upgrading an older inner-city home. It's a story of gradual change, informed decision-making and how ordinary households can play a meaningful role in the energy transition while improving everyday life.

Inside the world’s largest battery electric ferry

Right now, the world’s largest fully battery-electric ship sits in Hobart’s Derwent River, waiting to be put into service. The 130-metre China Zorrilla, built by Tasmanian shipbuilder Incat, will carry more than 2,000 passengers and 225 vehicles between Argentina and Uruguay entirely on battery power. Four battery rooms on board house more than 5,000 lithium-ion battery units, part of what is believed to be the largest battery installation ever put on a ship. Sitting onboard the vessel with Incat founder and chairman, Robert Clifford, explains how a family-owned Tasmanian company built a ship many in global shipping thought impossible and why battery-electric ferries are poised to reshape the future of maritime transport.

Why Australia’s energy devices need a common language

Australia’s energy system is increasingly relying on households. With more than four million homes now sporting rooftop solar, and batteries, EVs and smart appliances rapidly growing, consumer energy resources are becoming central to how the grid operates. But there’s a problem emerging beneath this transformation - many of these devices still can’t properly communicate with each other. Dani Alexander from the UNSW Energy Institute explains the importance of interoperability, the technical standards and systems that allow solar, batteries, EVs, retailers and networks to ‘talk’ to each other, and how a lack of interoperability could lock consumers into closed ecosystems and reduce consumer choice.
