Our EV charge source stats so far. In 2024 our average home charging consumed 5.36 kWh/day. Home charging is uber cheap.

BYD sells more EVs globally than Tesla.

All AC charging is slow charging.

Energy Made Easy is a good start and most definitely there are many $ to be saved however it has significant blindspots. A notable one is it cannot provide reliable advice for households on DNSP demand tariffs, which is the default tariff assignment in places like Sydney, Hunter, Illawarra and SEQ.

I contracted measles aged 30. It was the worst. High fever for days, no sleep for a week, hallucinations, suicide thoughts. Dreadful illness. I was very fortunate to be staying with family who looked after me. Took four visits to docs to diagnose. Probably not a patch on what others went through.

Ugh. I'd do the same.
Does your Ionic come with a spare of some kind? My MG4 does not, just a can silly goo and inflation kit. I have my own emergency plug kit but still considering getting a space saver for longer trips. Last car got sidewall damage one day and had run flats. [Sigh]

It's a combination of factors, they also have new models about to launch and many are probably holding off for those.

Indeed.
Self-consumption of output is key, as much as possible without need of home batteries. Other energy storage (hot water, EV, home thermal management) with smart management of discretionary loads is required. Hard to really nail it without batteries though as not all loads are discretionary.

I'm sure you already do but watch Australia as a canary in the solar coal mine (~40% of homes have rooftop solar). Here the feed-in credit is a minor fraction of import tariffs as it is valued the same as the generation wholesale spot price at that time of day, which is very low, even negative.

Still searchable here in Australia.

It depends on how well calibrated the battery management system's state of charge (SOC) measurement is. SOC accuracy drifts, especially when relying on DC fast charging or if doing lots of shallow discharge and charge cycles. SOC calibration requires a deep discharge and full slow (AC) recharge.

Here's all the current Tesla Supercharger locations for those with Tesla cars between Sydney and Stawell. It' be a doddle to perform the trip. Even Stawell has 12 x Superchargers. There are of course plenty of other networks, plus you'd stay somewhere with on-site AC destination charging facility.

I think there is a difference between "what you should or shouldn't do" and discussing the failure of public policy that was mandatory helmet laws. The data on the latter is pretty clear. We now have an entrenched anti-cycling culture and lack of focus on what really matters for safe cycling.
comment in response to

That's my point. There are two dozens things far more important for cycling safety than helmets, yet that's what authorities here focussed on - even having police task forces hunt down and issues fines. We have a deep rooted anti-cycling culture.
comment in response to

The primary reason was a rapid marginalisation of cycling in society. There is safety in numbers. Nowadays we have a generation of kids whose parents never rode a bicycle. Society views cyclists as pests, while our driving attitudes and infrastructure prioritise driver convenience over human life.

That's because mandatory helmets laws have been an abject failure of public safety policy.

It is hypocritical for sure but keep in mind the average Australian household net worth was $1.46M in 2023.
"Multi-millionaire Pete" might be needed to make the point.

German grid export/import balance.
comment in response to
post
Germany are doing well but we should note that Germany is now a net importer of electricity, mostly from France and Scandinavia - fortunately mostly low carbon energy sources (nuclear & hydro). So while 63% of German grid generation is renewables, it account for 55% of grid demand.

I note Dunc Gray Velodrome is about to be shut down completely as NSW Govt has decided to not support its operation.

Just because it could be done doesn't make it viable. The market needs to be able to support it. Singapore has triple the demand of SWIS and there's no guarantee that project is going ahead/viable.

HV transmission across the Nullarbor would be uneconomic. We'll need a lot of storage and VRE. It's coming but a bit slower than needed.

Yes, and Tas exports a bit as well. My point wasn't to say it's bad, just pointing out that some TAS and SA power does in fact still come from coal generators, they just happen to be interstate. Coal will end eventually.
comment in response to
post
SA and TAS still import coal power from Victoria at times. Pver last 12 months 20% of Tassie's power was imported from VIC, 10% for SA.

We've been house shopping. For the first time with our home moves I've been consulting our insurance broker for quotes on prospective homes. We ruled one out as a result, premium was substantial and they mentioned red flags. All climate related with some insurers refusing coverage.

Define 100% renewables. There is an "accounting" level of 100% renewables and then there is the real physics involved (IOW, no, not 100% renewables).

There's no way renewables made up 40% of our total energy supply. 40% of electricity generation perhaps. Fossil fuels make up 90% of Australia's total energy supply. We have a loooong way to go to have a renewable dominant energy supply.

Howdy. Hope this does not become another cesspit. In the meantime, my dog Beau say hi. Our local beach (Hungry Head).
