Electric Avenue: August 16

We're all charged up this week with some more big - and magical - machines; one of the best looking caravans we've ever seen (plus some EV towing info); how the big batteries in these big machines are starting to play a role in the energy system; a solar breakthrough that might allow us to put solar cells on our clothes, mobiles or cars; and if you liked the movie Don’t Look Up, you might be into a new play at Silo Theatre called Scenes From The Climate Era. 

We’ve showcased some of the surprisingly large machines that are, despite some scepticism, going electric. 

Almost without fail, those business owners and drivers are impressed with the performance, the reliability and the overall experience of electric equivalents and wouldn’t go back. 

EECA talked to Fulton Hogan, Reliance Transport and Leach & Co to find out what they thought about their new toys. And as ‘big diesel guy’ Adrian Ediss says in the video: ‘'These things are pretty magical”. 

According to EECA, “a billion litres of diesel – almost 30% of all diesel used nationwide – is burnt by off-road vehicles: adopting electric versions is crucial to cutting New Zealand's emissions.”

The Low Emissions Transport Fund is all about finding ways for businesses to invest in this equipment, so if you’re interested in getting a taste of the future, Round 14 of the fund is taking applications until 9 September.

More tow than a Roman sandal

Speaking of impressive electric machines, if you’re keen on a caravan (and have just come into a huge inheritance), then might we recommend this extremely flash option called Pebble, which is available for pre-order. 

It’s an all-electric travel trailer that’s “self-propelled and includes renewable energy capacity to stay off-grid for up to 7 days, with thoughtful design and industry-first innovation that remove the legacy hassles of RVing”. 

EVs often get criticised for their inability to tow heavy loads. Towing definitely does reduce range, just as it reduces fuel efficiency in a petrol or diesel car, but by how much depends on the weight you’re towing and whether the car has been designed to tow. 

One test showed an Audi e-tron decreased its range by one third when towing a caravan, while a Tesla Model 3 reduced its range by 50%. This will vary depending on the vehicle. 

Most EVs in New Zealand today are not designed for towing significant amounts, but this is expected to change, and the USA is already demonstrating EVs that can tow large loads long distances.

These big trucks have big batteries and those big batteries could be quite valuable for things other than driving

“For the first time ever, electric Ford F-150 drivers are getting paid to run their homes from their pickup truck batteries during peak hours to help meet grid demand … When it rolled out the F-150 Lightning in 2021, Ford made a splash by designing a backup power mode: If the owner’s house loses power from the grid, the capacious truck battery can run the house instead. That’s a clean and quiet alternative to a fossil-fueled generator, but it hinted at something far more potent: What if you could put that battery to work all the time, for the benefit of not just the driver but the entire electricity system?”

Baltimore Gas and Electric in the US is trialling that scheme, offering payment to those who send energy back to the grid when it’s needed and reducing the strain on the grid by charging them back up at times of low demand. 

As Rewiring Aotearoa CEO Mike Casey wrote on Newsroom, we need to start thinking about customers as part of the infrastructure, something that the market has not been set up to handle. When we fairly reflect the value that technology like batteries, solar and even cars can offer, that will speed up adoption. 

Brighter ideas

Solar is already the cheapest form of energy humans have ever developed, but there’s still plenty of research happening to make it even more efficient so we can generate more electricity from the sun with less material. 

While putting panels on a roof is a good use of space, large solar farms take up a lot of land that could be used for other things. At Oxford University, a new breakthrough means we might not even as many of those panels in the future because we might be able to put solar cells on our clothes, mobiles or cars. 

‘By using new materials which can be applied as a coating, we’ve shown we can replicate and out-perform silicon whilst also gaining flexibility. This is important because it promises more solar power without the need for so many silicon-based panels or specially-built solar farms,’ said Dr Junke Wang, Marie Skłodowska Curie Actions Postdoc Fellow at Oxford University Physics.

We look forward to seeing Mike Casey on social media in a solar powered Swanndri.

Until this takes off, we still need to clean all those panels, and this is one of the coolest ways we've seen to do that.

We look forward to the next evolution: a cheap drone with a Roomba attached.

Watch and learn

If you liked the Netflix movie Don’t Look Up, you’ll love this, says Arlo Green, star of a new play at Silo Theatre called Scenes From The Climate Era. 

Written by Australian playwright David Finnigan, the son of a climate scientist, the show “offers glimpses of hope for humanity in our collective power to affect change".

“I was raised to live in a world that was a certain way. That world no longer exists. Now we’re starting to take stock of the world we actually live in, and it means rethinking everything.”

At Rewiring Aotearoa we like to be a positive and pragmatic voice in the climate discussion and electrifying your home and transport is likely to have a bigger impact on your emissions than any other decision you make. It’s also one of the only ways we will reach our global climate targets. So let's rethink those fossil fuel machines.
