RNZ's Eloise Gibson looked into the question of whether gas or electric appliances are cheaper and the evidence, as outlined in Rewiring Aotearoa's Electric Homes report, is pretty clear: even with the upfront costs of replacement and finance, running electric hot water, electric heating and electric cooking is much cheaper - and less toxic - than using fossil gas and it's cheaper still if you've got rooftop solar and batteries. It makes no economic sense for new homes to connect to gas in New Zealand and if your old gas appliance breaks down, it pays to make your next purchasing electric. "Compared with using piped gas heating, hot water, and cooking, a fully electric home could save almost $11,000 over 15 years for upfront costs and energy bills, the study found. Compared with using bottled LPG for heating, hot water, and cooking, a fully electric home could save almost $20,000 over the same period."
"Mike is probably the most public face for advocating for decarbonisation through electrification in New Zealand, and someone who is demonstrating outstanding leadership."
New Zealand farmers are renowned for their ability to produce things like lamb, beef and dairy, but there's a new product they're moving into: renewable electricity. A new report by energy transition charity Rewiring Aotearoa says the benefits to farmers of installing solar and battery systems include cheaper power, resilience to outages and being able to make money from selling electricity back to the grid. Maniatoto farmer Becks Smith said installing solar to power her irrigation systems is the logical next step for the farm business. "We're actually really good at producing off solar power, that's what we do with our grass every day," she told Newshub. Smith is planning to install solar to generate electricity on farm to run her irrigation pumps during summer, while in winter when the pump is turned off, she can still generate electricity and sell it back to the grid. She said it improves business and community resilience. "Farms have the opportunity to be local electricity hubs to supply into local networks. Should the infrastructure be damaged in a natural disaster, we have the ability to support our communities."

A collaboration between Destination Queenstown and Queenstown Business Chamber of Commerce, the initiative is powered by Aurora Energy, inviting local businesses to unlock the economic benefits of electrification, saving on costs and growing their business while decarbonising. "One of the most effective ways to decarbonise is by going electric. We’re excited to have experts joining Electrifying Queenstown to share knowledge and practical ideas to support the tourism and business community to shift to a sustainable future,” says Destination Queenstown Chief Executive Mat Woods.
Read moreWhat if you could arrange a half-day in the debating chamber when I could bring a group we’re calling the “Coalition of the Willing” to share constructive, economic solutions around the opportunities climate change and sustainability offer to Aotearoa New Zealand? Opportunities that could significantly lift our GDP, reduce billion-dollar infrastructure costs, create high-value jobs and maximise returns from our forestry and geothermal assets. 1. ReWiring Aotearoa (Mike Casey and team): Current strategy involves spending billions on infrastructure to move electricity from fast-tracked wind and solar farms, potentially doubling household costs. Casey’s fossil-fuel free, fully electric orchard in Central Otago shows how rooftop solar panels and batteries can deliver power directly to homes and businesses at a fraction of the cost, building energy resilience. The importance of this was highlighted this month. As we faced those potential power cuts, Casey’s farm actually delivered excess electricity back to the grid. While the farm uses 900 per cent more electricity than before it was electrified, most of that is self-generated or stored off the grid during off-peak times. Electricity is sold back during peak times. The annual saving on diesel is $40,000 a year. Imagine every farm in the country working like that.

The New Zealand Green Building Council's new report 'Closing the Gap' shows that improving buildings could save New Zealand almost $40 billion and slash emissions. "Improving the standard of new buildings and electrification are no-brainers. The sooner we get started, the more emissions we’ll avoid and the more money Kiwis, businesses and farmers will save," says Rewiring Aotearoa CEO Mike Casey. Andrew Eagles, NZGBC chief executive says: "As New Zealand is bound by law and international trade agreements to reduce our emissions in line with the Paris Agreement, our buildings are a key lever." Actions explored in the report include: Staggered improvements to the building code, requiring new buildings to measuring operational and upfront carbon emissions at consenting stage from 2025, a 20% reduction in both upfront and operational emissions by 2028, 40% reduction in upfront carbon emissions and near zero energy in operation by 20230, and a 60% reduction in upfront carbon emissions and near zero energy in operation by 2034. Require all homes put up for sale or rent to have an Energy Performance Certificates by 2028, and all office buildings over 1,000sqm put up for sale or lease to have a NABERSNZ certificate from 2026. Phase out of fossil gas in homes and commercial buildings. Suggested actions include expand the Warmer Kiwi Homes programme to subsidise electrification of home heating from 2027, converting 25,000 homes a year. End new residential fossil gas connections from 2026. Implement a concerted programme, building on the successful replacement of coal boilers in schools and hospitals, to subsidise 10% of commercial buildings per year from 2026 to electrify.

[At 2 mins] Meanwhile plenty of Kiwis are taking energy security into their own hands, like retired chartered accountant Mike Campbell, who's moving into a retirement village where he's installed solar panels [and a battery]. "I'm producing more energy than I can actually use, even though I've got an electric car, and it goes off to the grid and it feeds somebody else." He would love to see the Government help young people install solar and battery systems. "They can help young people to reduce their power bills by a lot of money."
Read moreYesterday I spoke to Rewiring Aotearoa CEO Mike Casey and Octopus Energy NZ Chief Operating Officer Margaret Cooney about the current state of our electricity market and what could be done to fix it. Casey talked about how he earned extra money by exporting power into the grid at sky-high prices from the solar panels and batteries he installed to fully electrify his cherry orchard in Cromwell. Cooney talked about how Octopus Energy UK pays customers to reduce demand and uses automation to match supply and demand. She also talks about a way to make the market more competitive and viable for independent retailers buying from the wholesale market.
A comprehensive new research report released by EECA (the Energy Efficiency & Conservation Authority) unpacks where Kiwi homeowners are at with household electrification, identifying the opportunity when it comes to energy use, emissions, and running costs. The research finds over a third of key appliances (36%) in use – for cooking, heating spaces, and heating water – are over a decade old. The average for vehicles (including EVs) is even older at 14.9 years. Among those surveyed, ‘end of life’ of the current appliance was by far the main reason consumers will invest in new, with 75% of people saying this was a key motivator for them.

For a country that trades on its green brand and reputation as a trustworthy international counterpart, there is no realistic alternative but to follow through on our climate commitments. Failure to do so would have serious financial risks ... The size of this country’s NDC liability in future years will depend on how much action is taken domestically. Every extra tonne that we can reduce at a reasonable cost is one that we will not need to purchase offshore. All of this helps make the case for investment in ambitious initiatives such as accelerated electrification proposed by Rewiring Aotearoa and Recloaking Papatūānuku.

Andy broadcasted his show today LIVE from the World's First 100% Electric, Zero Fossil Fuel Orchard, with all the broadcast equipment powered by Monarch Tractor, the world's first fully electric tractor. Mike Casey, the man behind Forest Lodge Orchard, spoke about the reality of running such an enterprise and how others can follow suit.
Bucking a common misconception, New Zealanders no longer say recycling is the most effective action they can take to reduce climate pollution ... A recent study from Rewiring Aotearoa, which didn’t attempt to measure consumer sentiment towards climate-friendly actions but did examine the benefits from electrifying homes, found New Zealanders can now save between $1400 and $4700 a year by fully decarbonising their households. This makes New Zealand one of the first countries in the world to reach a “tipping point” where electrifying households is now cheaper than relying on fossil fuels. “If we use more affordable, locally produced electricity – both from our highly renewable grid and through more customer generation – to run our much more efficient electric machines, households and businesses will save money, our energy system will be stronger and more resistant to shocks, the country’s balance of payments will be billions better off because we won’t need to import as many expensive fossil fuels, and our carbon emissions will shrink,” the report found.

Mike Casey likes to call himself an “electric cherry orchardist from New Zealand"... Casey argues that rooftop solar was the gateway that enabled him to electrify his entire orchard. “It’s so significantly cheaper than a litre of diesel that it would just make absolutely no sense to buy another diesel machine once you are taking advantage of your rooftop solar.”
Electrifying your household appliances - which in most cases means ditching a gas cooktop, gas heating and hot water - can save the average household more than $1000 per year, according to data modelling recently commissioned by the Energy Efficiency Conservation Authority [and Rewiring Aotearoa]. The study also found annual running cost and lifetime-cost gains from solar and swapping out a petrol or diesel vehicle for an EV - at least if you use cheaper charging at home rather than pricey public chargers, even allowing for impending road user chargers.
Read moreIn the next year alone, over half a million purchase decisions will be made by New Zealanders on household appliances and vehicles, and this pattern is expected to continue. To help New Zealanders make informed decisions when they are in the market, EECA has unpacked the yearly lifetime saving opportunities - across energy, emissions and household bills, that can be achieved through choosing the most efficient, electric options. As a snapshot of running costs alone - New Zealanders could save around $1,000+ per year in energy costs. When upfront costs are included, this could save $10,000-$20,000 over a 15-year appliance lifetime. Every household is different, but the data says that for most - it pays to go electric.

Every Sunday night I sit down with my family – and about half a million other New Zealanders – to watch Country Calendar. It’s a love letter to the land and an ode to innovation and I’m always inspired by the resourceful rural folk coming up with clever ways to keep the coffers full. That is becoming increasingly difficult, however. Farmers are battling economic headwinds, global competition, synthetic substitutes and expensive – some might argue excessive – compliance, so anything that can save or make them money is about as rare as a hen’s tooth. But there is something that could potentially achieve both of those things: electricity ... The No 8 wire mentality is part of our national mythology. Early generations of farmers had to learn to be self-sufficient and make the most of the resources they had around them. What farmers have around them now is plenty of land, lots of sun and increasing demand for renewable electricity. Using and creating more electricity on NZ’s farms is in everyone’s economic and environmental interests, so let’s take a leaf out of Bill Gallagher’s book and make that No 8 wire electric.

Rewiring Aotearoa believes one such outcome from market innovation is supporting the electrification opportunity for Aotearoa New Zealand. The Commission has the opportunity to play an active role in driving this not just through the energy market, but also through the personal banking market. It is important that these functions are not seen in isolation, but as a system, to better realise the Commission's role in delivering on NZ’s emissions reduction plan, and 2050 Nationally Determined Contribution.

Read moreForest Lodge Orchard has taken out the Norwood Farming Efficiency Award and the NZFET Innovation Award at the Otago Farm Environment Awards. "Technology and sustainability are the hallmarks of this Cromwell orchard that has grown its harvest exponentially since being developed from bare ground in 2019 ... Right from the start, owners Mike and Rebecca Casey, and Euan and Rachel White have been striving to electrify all orchard methods and equipment – a goal they have achieved. They have an electric tractor, have electrified the orchard’s irrigation pump, installed New Zealand’s first electric frost–fighting fans and are developing an electric foliage sprayer. In 2022, they set themselves a challenge of going completely fossil-fuel-free in the orchard. This will potentially save about $50k per year in energy bills and continues to drive greater creativity in finding or developing alternative approaches."

We view the package as a critical step in improving energy system outcomes for all consumers. We consider retailers paying consumers fairly as a critical step, and we are mostly satisfied with the Task Force’s approach to this (initiative 2C) and think it will create better outcomes for New Zealand consumers and the energy system as a whole. In contrast, the Task Force’s preferred option around how distributors are required to reward peak input from consumers (initiative 2A) will not in our view meet the Task Force’s (or the Electricity Authority’s) stated objectives.

Successive governments have funded report after report and numerous fly-in visits by Ministers have failed to change this situation for the local community. Rewiring Aotearoa believes the opportunity is to harness existing solar and battery technology to deliver significant cost-of-living savings and reduced emissions at scale via electrification on Stewart Island right now. With financed solar and batteries, electricity usage costs for residents could be halved without delay. Rewiring Aotearoa has been engaging with the local community, who have been sending us their power bills. On Saturday 27th April some of the Rewiring team visited Stewart Island (including Mike Rewi who has strong whakapapa to Stewart Island). What we are hearing from this community is many locals fear the proposals and the likely “preferred option” will be focused on replacing current diesel generators, not on reducing the cost of energy for consumers. Our proposal outlines Rewiring Aotearoa’s pitch for an alternative approach to develop a community-led energy solution for the Island.

However, today there is a systemic bias towards traditional infrastructure largely because it is seen as significantly more ‘dependable’. There are a variety of historical reasons for this. Our primary context to this submission is that many of the assumptions and rationale for this bias are quickly falling away, and DPP4 provides a significant opportunity for the Commerce Commission (the Commission) to reset the assumptions and correct some of this bias.

The EA has the ability to take a leadership role in the energy transition on behalf of electricity consumers. Far more than the Commerce Commission’s oversight of EDBs investment plans, the EA’s network pricing workplan gives consumers agency in the development of the electricity system. When consumer agency is stifled, they will likely have significantly worse financial outcomes on their bills. Much of the necessary changes have been demonstrated already locally or overseas, and the remaining question is not if the changes are possible but if we as a nation will have the courage to implement them on the timeline required to drive better energy transition outcomes for consumers.

Read moreSolar on our rooftops, farms and businesses can displace the emissions generated by burning fossil fuels in our homes and especially our cars, provide the extra electricity we need to run our electric machines, help bring the cost of electricity down for everyone on the network, and improve our energy security by keeping water in our hydro lakes for when we need it most.
Read moreWe often hear from people who aren’t sure if switching to an electric alternative is the right move. One of the most common questions we get asked is ‘will switching to an electric machine actually reduce my carbon footprint if creating the new machine or materials produces emissions?’It’s a fair question, and we completely agree it’s important to think about the full life cycle of the products we buy and use. Electric alternatives, including vehicles, often produce more emissions than fossil fuel equivalents during manufacturing. But, over the lifetime of the machine, they create much less carbon pollution because they don't burn any fuel.
Read moreFossil fuels for homes, transport and industrial processes make up the vast majority of the country’s total energy consumption. Electrifying the machines that use these fossil fuels means we will use more electricity but much less energy overall.
Read moreAn electrified energy system is actually full of opportunities for redesign, reuse, recovery and recycling. There are opportunities for innovators and entrepreneurs to generate value across the lifespan of every energy asset, not least the return of its components to the manufacturing cycle. To explore this further, Rewiring Aotearoa has partnered with Circularity, local experts in circular design and strategy, to explain what the circular economy is, how to integrate circularity into the design of energy systems, and the role of policy strategy to make it happen.
Read moreThere are no free lunches in energy. But some lunches are far, far cheaper than others. Electrifying everything will massively reduce the overall material and energy requirements of the global energy system. This can be said with high confidence. To be sure, renewable energy systems take materials and energy to build. But this is dwarfed by the mind-boggling scale of extraction, consumption and wastefulness of fossil energy.
Read morePeople sometimes talk about ‘carbon tunnel vision’ – that is, the single-minded pursuit of emission reductions at the sake of everything else. But this is the wrong way to think about electrification. It isn’t only about emissions (even though preventing the world from dangerous overheating is quite the co-benefit). It isn’t only about the tech or the kit: the rooftop solar panels, the batteries, the electrified appliances and vehicles. These are just the means to an end. Electrification is about people and it is a fundamentally better way to power our lives and livelihoods.
