Why just banking on home batteries is 'irrational'

  • No plans to transition off gas exports

Cracking the energy efficiency code

In an interview with The Energy ahead of a keynote at the Energy Efficiency Council summit this week, Secretary General of Efficient Buildings Europe and Director of the Renovate Europe Campaign Adrian Joyce says relying on mass adoption of home batteries and too much roof-top solar is “irrational” at best and wasteful at worst.

“What’s best to do? Have old or renewable energy and don’t worry about the quality of the buildings you’re in and the level of comfort that delivers or be responsible, have a low energy consumption and high comfort and well-being buildings,” he says. “I know where my heart is.”

'Progress' on industrial energy savings

​​Energy efficiency, measured by the rate of change in primary energy intensity, will improve by 1.8% this year, up from 1% in 2024, according to the latest estimates issued by the International Energy Agency (IEA).

“Energy efficiency has the power to enhance people’s lives and livelihoods through greater energy security, more affordable bills, improved economic competitiveness and lower emissions.”
IEA Executive Director Fatih Birol

But the “progress” detailed in the Energy Efficiency 2025 market report falls short of an agreement two years ago for a 4% annual improvement in global energy efficiency by 2030.

Rising industrial energy consumption, combined with a decline in industrial energy intensity improvements, is a key driver, a new Progress Tracker released with the report shows, with energy efficiency improvements in the United States and the European Union slowing to below 1% from 2.5% and around 3% respectively.

No plans to transition off gas exports

Australia joined almost 90 countries in signing up to a Belém Declaration on the transition away from fossil fuels, which appears to be at odds with the future gas strategy.

Bill Hare, CEO and senior scientist at Climate Analytics, said the decision was welcome but out of step with Australia's continued approvals of coal and gas projects, most recently the North West Shelf licence extension to 2070.

Speaking to reporters at the G20 summit, Prime Minister Anthony Albanese said there were no plans to taper down Australia’s gas industry and exports, insisting the move was compatible with a gas strategy that locks in production to 2050 and beyond.

“Well it is needed. It’s a part of the transition which is occurring. What you need to back up renewables is firming capacity, that’s what’s enabling the investment to occur. And all of the energy experts say the cheapest form of transition is renewables backed by gas, backed by hydro, backed by batteries. That’s Australia’s position.”
Prime Minister Anthony Albanese

Countries at COP30 pledged more than US$1 trillion by 2030 to expand power grids, energy storage and invest more broadly in the energy transition under the COP30 action plan.

“Together, Australia, Türkiye and the Pacific will strive to ensure COP31 is a success. We will maintain a focus on doing all we can to keep 1.5 degrees alive, as this is such an imperative for our planet and our Pacific friends,” Climate Change and Energy Minister Chris Bowen told the final COP30 plenary session, beginning his role as lead negotiator.

The Opposition says Australia cannot afford to have “a part-time energy minister”.

Expert view

"Australia’s surprise decision to sign the ‘Belém Declaration on the Just Transition Away from Fossil Fuels’ is a positive sign. It suggests Australia may finally be ready to start grappling with its responsibilities as one of the world’s largest exporters of coal and gas.

Australia signed the declaration just days after one of its largest markets for thermal coal, South Korea, made an international commitment to phase out coal-fired power. Australia has much to gain by capitalising on green export opportunities. It should modernise its energy ties with key trading partners, including Japan and South Korea, to move collectively away from risky fossil fuels as fast as possible. Australia would go some way to restoring faith with the Pacific if it stops approving new coal and gas projects.”

Expert view

“The inclusion of ‘information integrity' in the COP30 outcome is a genuine watershed moment, recognising that information integrity is essential for effective climate action. This outcome signals a major step forward in addressing escalating risks in information spaces — from disinformation to the harassment of scientists — and in ensuring that evidence-based information is available to all.”

A provision in proposed environment protection laws that would allow coal and gas projects to be approved if they were in the national interest could be scrapped as the government woos the Greens to get the package of bills passed as soon as this week.

Regulation

The core flaw of the Solar Sharer offer is that it mandates a zero-dollar ($0/kWh) retail price for a specific window while leaving the costs to supply that energy intact, the Australian Energy Council warned. Retailers should be granted an exemption from Renewable Energy Target certificate obligations for electricity consumed during the free period and the default market offer/Solar Sharer offer pricing methodology should explicitly allow for the recovery of the portfolio costs, including the hedging premiums required to manage the volatility created by the Solar Sharer, General Manager for Retail Policy Jo De Silva said in a submission.

AEMO has asked rule-maker, the ­Australian Energy Market ­Commission, to mandate that coal power plants give authorities five years ­notice of any plan to shut down. The change would add a further 18 months on top of the current 3½-year notice period. (The Aus)

The Australian Competition and Consumer Commission (ACCC) has issued a recall for Sigenergy for the SigenStor single phase 8/10/12 kW energy controllers with quick connect AC plug. The AC plugs in the home battery system are at risk overheating and may cause a fire.


Technology

Despite a growing understanding of the benefits of bidirectional charging, V2G has struggled to move beyond pilots into sustained commercial deployment. The core issue is no longer technical feasibility, it’s the inability to translate its value into predictable, durable revenue streams that attract private capital. Understanding why this gap persists is essential to understanding what it will take for V2G to scale, energy economist Steve Letendre writes. (V2GNews)

Instead of widespread implementation, negotiators in Belém agreed not to significantly change existing Article 6 decisions on carbon markets and to channel nearly $30 million to the new Paris Agreement Crediting Mechanism (PACM) from the Kyoto-era Clean Development Mechanism (CDM).

Supply-side net-zero technologies have received far more policy support so far than demand-side energy reduction, which a group of researchers examines in the British context in the latest edition of Nature Energy, finding social and behavioural changes to how people travel, work, heat their homes and consume goods could cut total UK energy demand by between 18% and 45% by 2050 compared to today.
