Balcony solar, small, plug-in systems you can hang off a balcony or fence, has exploded in Germany, with millions of households now generating their own power. Low cost solar panels and micro-inverters, regulatory changes that allow simple plug-in installation without the need for an electrician, and soaring energy prices after Russia’s invasion of Ukraine have all driven the surge. What began as a DIY workaround is now an off-the-shelf consumer product, reshaping how people think about energy at home. But balcony solar has its detractors, with resistance emerging from large co-operative and municipal landlords who control much of the rental market. Sebastian Müller, the chair of the German association for plug-in solar, Balkon Solar, explains how the movement gained momentum, what’s holding it back, and what it reveals about the roll out of consumer-led energy systems.

As rooftop solar, home batteries and electric vehicles transform how energy is generated and used, Australia’s electricity networks are being forced to adapt. At last week’s Energy Networks conference in Adelaide, consumer energy resources were top of mind for many network leaders, even though networks in Australia are constrained by rules designed for a one-way grid and prevent them from dealing with consumers. Some networks argue they need a bigger role to manage consumer resources and avoid costly infrastructure overbuilds and keep prices down. Critics warn that expanding network powers will entrench their market dominance and stifle innovation. New research from EA Technology, which advises networks around the world, suggests that networks need a better understanding of how, when and why consumers use electricity. Chief Commercial Officer at EA Technology discusses their recent survey of more than 8,000 consumers across Australia, the UK and New Zealand.

As renewable energy projects expand across regional Australia, the question of who benefits is becoming increasingly important. Governments are introducing community benefit guidelines to ensure host regions share in the economic gains – WA is the latest - but results so far have been mixed. Kim Mallee, a co-director at the Community Power Agency, argues that community benefits can’t be treated as an add-on – they must be shaped by communities themselves. Drawing on international examples from countries like Denmark, Scotland and Ireland, she explores how ownership, co-investment and community-led models can deliver deeper, longer-term value. CPA’s new report, Power in Partnership, outlines how these approaches could work in Australia and we can move beyond compensation towards genuine partnership in the energy transition.

Rooftop solar, home batteries and smart technology are transforming Australia’s electricity system and helping many households cut their power bills. But a controversial draft review from the Australian Energy Market Commission has sparked debate about whether electricity pricing is shifting costs onto people who've invested in consumer energy resources, or alternatively, those who can least afford them. Gavin Dufty, the national director of energy policy and research at the St Vincent de Paul society, draws on years of data from the Vinnies Tariff Tracker project to show what households actually pay for electricity across the country. He argues the current system may be creating new inequities between households able to invest in solar and smart technology and those who cannot, including renters and low-income households. At the centre of the debate is a difficult policy question: should electricity pricing reward households that reduce their reliance on the grid, or should everyone pay more to simply stay connected? The outcome of the AEMC’s review could shape how the costs of Australia’s energy transition are shared.

What if the clean energy transition is ultimately led not by utilities or renewable energy companies, but by the data and AI industry? Luis F. Gonzalez, Chief Data and AI Officer at Aboitiz Power, argues that as data and energy become more intertwined, it will be the data sector that finances, shapes and champions decarbonisation. He says AI doesn’t just consume electricity — it changes the economics of who builds and controls energy infrastructure. And although he doesn’t want Face Book to run our power grids, he argues the only type of company capable of massive data brokerage for millions of consumer energy resources is a data company. While openly optimistic about the benefits of intelligence-driven systems, he also acknowledges the risks of monopoly power and that energy regulators are not yet ready for what’s to come.

Australia’s home battery rollout is accelerating, but many households may not realise they’re buying systems that are effectively locked to a single manufacturer’s software. Tech entrepreneur Simon Hackett explains why a lack of interoperability strips consumers of real control over batteries they’ve paid for and how closed, cloud-controlled systems risk higher costs, stranded assets, and weakened trust in virtual power plants. He outlines an alternative vision where open software allows households to optimise their energy use, respond to real-time prices, and create real power plants rather than virtual ones which serve someone else’s business model. At stake is whether Australia’s battery boom empowers households, or quietly hands control back to manufacturers and retailers.

Apartment residents are largely shut out of Australia’s rooftop solar advantage, with only 3.5% of apartments having solar. In this episode of SwitchedOn Australia, we explore whether balcony solar could change that by allowing apartment owners and renters to plug into cheap, clean power without owning a roof. Brent Clark, CEO of Wattblock, explains why balcony solar has taken off overseas — particularly in Germany, where more than a million plug-in systems now hang from balconies — and why regulation, not technology, is the real barrier. Australia’s safety rules, metering requirements and strata laws make balcony solar that much harder here. So what needs to change for it to work safely and fairly in Australia, and enable gigawatts of untapped solar potential sitting on apartment buildings to be realised.

Australia’s retail energy market promises competition and choice, yet many households feel confused, overcharged and stuck. Former chair of Victoria’s Essential Services Commission Ron Ben-David argues the problem isn’t just high prices, but a market design that assumes consumers behave like textbook economists. He explains how “buyer beware” has produced a loyalty penalty, rising mistrust and an endless layering of consumer protections that fail to address the root cause. As the energy transition accelerates and decisions become more complex, he warns the system is becoming harder — not easier — for consumers to navigate. He makes the case for a fundamental shift to a consumer duty that would require energy companies to act in their customers’ best interests. Without rebuilding trust, he warns, the energy transition itself is at risk.

When renewable energy developers first approached the Hay Shire Council in south-west NSW, the council saw both opportunity and risk. With the region designated as a Renewable Energy Zone and major wind projects on the horizon, they knew the energy transition could bring real benefits, but also real community division. Rather than sit back and let events unfold, they took the lead, helping ensure the community would engage with the transition. In partnership with the community, Hay Shire Council developed a proactive, inclusive process that not only kept the community informed, but led to a clear, community-driven set of benefit proposals, ranging from long-term affordable energy to supported housing. Ali McLean, the Council’s Economic Development Manager, shares how local government can shape the future when it steps up early and listens closely.

Last August, Dr Saul Griffith joined SwitchedOn Australia live on the Gold Coast to talk about his new book Plug In! which shows why households are central to driving Australia’s clean energy transition. He explains how electrification can cut emissions fast, save money, and reshape the way we use energy at home and in our communities. Saul shares insights from his career advising governments, including his role in shaping the US Inflation Reduction Act, and his work with Rewiring America and Rewiring Australia. He speaks candidly about consumer power, culture wars, and the politics of accelerating change. And he makes the case for an ‘army of consumers’ to demand a better deal from Australia’s energy system.
