Is Australia Finally Turning Its Back on Coal? Lily D'Ambrosio | Deep Dive Australia 04
20/07/2026 | 51 mins.Victoria is undertaking one of Australia's most ambitious electricity transitions. The state is aiming for 65% renewable electricity by 2030 and 95% by 2035, replacing ageing coal-fired power stations with renewable electricity, batteries and offshore wind while keeping the lights on and consumers' bills down.
This week on Cleaning Up’s Deep Dive Australia, Michael Liebreich is joined by Lily D'Ambrosio, Victoria's Minister for Climate Action, Energy and the State Electricity Commission, who has overseen the state's energy transition for more than a decade.
Together Minister D’Ambrosio and Michael examine the policies driving the transition, from renewable energy auctions and large-scale batteries, to offshore wind and transmission planning. Michael also challenges the Minister on some of the most controversial aspects of Victoria's strategy, including unpublished modelling, coal closure agreements, and the politics of moving households away from gas.
Topics:
Victoria's energy transition and the role of state governments
Replacing coal with renewables
Batteries, electricity markets and falling wholesale prices
Coal plant closures and investor certainty
Transparency, modelling and political accountability
Transmission, community opposition and Renewable Energy Zones
Offshore wind and the future generation mix
Gas, household electrification and cost of living
Leadership, public confidence and delivering the transition

CSIRO: Commonwealth Science and Industrial Research Organisation- China transformed solar from one of the world's most expensive energy technologies into the cheapest source of electricity in just a couple of decades. And now it’s doing the same with batteries, with prices plummeting around the world.
This week on Cleaning Up, Bryony Worthington is joined by Alex Shoer, Managing Director of GridVest, who spent almost a decade building renewable energy businesses in China before bringing those lessons back to the United States.
They discuss the lessons behind China's clean energy success, the evolution of solar subsidies, and why battery storage is becoming essential for everything from renewable energy to AI data centres. They explore whether collaboration rather than competition will shape the next phase of the global energy transition, and in which technologies the U.S. still holds a competitive advantage.
Topics covered:
China's blueprint for scaling clean energy
The impact of ending solar subsidies
Why batteries are becoming more valuable than solar alone
Can AI and data centres accelerate the battery boom?
Ford, CATL and the future of global partnerships
Competing vs partnering with China
Financing the next generation of energy infrastructure
The future of battery tech and U.S. innovation

AHJ: Authorities Having Jurisdiction Are Solar And Batteries Undermining Australia’s Grid? Deep Dive Australia 03: Marc England
13/07/2026 | 56 mins.Australia's electricity networks are entering a new era. As rooftop solar, battery storage and electric vehicles demand reshape the grid, the role of distribution networks is changing from simply delivering electricity to actively enabling a smarter, more resilient and affordable energy system.
For the third episode of our Deep Dive Australia series, Michael sits down with Marc England, CEO of Ausgrid, one of Australia's largest electricity distribution businesses, to explore what that transformation looks like in practice. Ausgrid is responsible for supplying electricity to millions of customers across Sydney, the Central Coast and the Hunter Region in New South Wales.
Marc reflects on how networks have to become intelligent, flexible and community-focused while balancing commercial realities with public service. He shares how distribution companies like his are adapting to an increasingly decentralised electricity system, where balancing reliability, affordability and customer expectations has never been more complex. From the growing role of battery storage and managing unpredictable energy flows, to supporting the rapid rise of data centres and preparing for extreme weather events, he explains why networks will play a critical role in delivering a successful net zero future.
Also, Michael travels inside the electricity tunnels beneath Sydney, to see how Ausgrid has built a resilient electricity system for Australia’s financial capital.
Topics Include:
The evolving role of electricity distribution networks
Balancing commercial success with community responsibility
Battery storage and building a more flexible grid
Managing the rise of rooftop solar and distributed energy resources
Preparing for growing electricity demand and data centres
Building resilience for extreme weather and changing energy patterns
Leading innovation through Australia's energy transition

CIS - Capacity Investment Scheme- South and Southeast Asia face a different challenge to many developed economies. As the regions continue to grow, so too does demand for energy, transport and industry. The question is whether that growth can be powered by cleaner technologies from the start.
In the second of our episodes recorded from Singapore, Michael meets Marie Cheong, founding partner at 100x100, a climate tech venture builder and VC for South and Southeast Asia. Previously, Marie co-founded WaveMaker Impact, where she helped launch climate startups addressing some of the region's biggest opportunities for decarbonisation.
Marie explains why climate innovation in emerging South Asian markets requires a different approach. They discuss investing across the region, growing energy demand, using AI to decarbonise manufacturing, and why there are no "silver bullet" solutions to climate change.
Marie also takes Michael to the People Bee Hoon noodle factory, which makes rice vermicelli noodles to see how Desmond Goh, the factory’s director is using AI to improve his operations. Michael meets to Desmond and Muun AI founder Kathryn Knight about how better use of data can help cut emissions and waste.
And at the end of the episode, a very special announcement… stay tuned.

06/07/2026 | 1h 8 mins.Australia is navigating an extraordinarily complex energy transition. It is both a major exporter of fossil fuels and a global leader in rooftop solar, while recent disruption to fuel supplies has reinforced the importance of energy security alongside decarbonisation. As the country prepares to co-host COP31 alongside Türkiye, the choices it makes will have implications well beyond its borders.
This week on Cleaning Up, Michael Liebreich sits down with Chris Bowen, Australia's Minister for Climate Change and Energy. Chris explains how Australia responded to the recent fuel crisis, why he believes the road to net-zero starts with households, and how the government is balancing affordability, reliability and emissions reduction.
Chris and Michael explore Australia's rapid growth in rooftop solar and home batteries, why electric vehicles have been slower to take off, the challenges of expanding the electricity grid, and what Australia's joint leadership of COP31 means for its role on the global stage. Throughout, Chris explains how he sees the challenge of making the energy transition practical, affordable and politically achievable.
Topics include:
How Australia avoided fuel shortages during the global energy crisis
Why Minister Bowen believes the path to net zero starts with households
How to make rooftop solar and home batteries work at scale
The challenge of electrifying transport in Australia
Building the grid needed for a renewable energy future
Balancing climate ambition with political and community support
What Australia's energy transition can teach the rest of the world
