In case you're wondering - we did a big green reno about 10 years ago - double-glazed all windows, bulk and foil insulation in roofs, walls and floors, all lighting is LED and we added a new solar passive kitchen and living room with concrete flooring for thermal mass, etc etc. The new part of the house has never needed AC. Whole house charged rain-water system as well.

That’s great and they’ll be plenty of case like this, but there’ll also be plenty of cases opposite to this I think.

And you kind of proved my point about the haves and have nots with your post as well - not having a go at that, I’m not in the latter category myself and I’ve been trying to do similar at our house - to the point we have cut our heating bill by around 80% this Winter - we only use the heater for one quick warm up of the house on a cold night and that’s it - most nights we don’t even have it on at all, but all of this talk about EV’s and how to power them, batteries, solar etc is the domain of the well off, no Joe Blogs living from one pay to the next. They will be the ones that hurt the most from this rapid rush to change and the overall monumental cost that goes with it.

there's no 'rapid rush to change' this is the sort of thing deniers come up with as a counterargument to any change. Decarbonising the grid is essential for continued human existence and it has the bonus of making life better for everyone from the richest to the poorest.

Do you have similar concerns about tall buildings and large trees?

What was your role on the wind farm project?

Daily 12kwh in my dreams , If only I could delete the bloody swimming pool , Even during winter the pump runs 2 hours a day, Ive just had the smart idea to have it run at night so it does not reduce our solar feed in , We get about $0.70 FIT & buy at about $0.23

In this bill cycle we have only had 2 sunny days & its been freezing so have heaters on in the house.

Usage high on Sept 1 because I put 18kwh into the Landy , (but as you can see that's a lot cheaper than petrol) Usually charge once every 4-5 days. Obviously charge at night .

Attachment 180719 Attachment 180720

Im not sure about the 'haves and have nots' argument. Check out Toorak or Vaclause on google earth Lowest take up of solar panels compared to less well off areas. They don't give a ****e about energy prices , yet are a high consumer of Teslas (and LandRovers too)

Not wrong about the pretty dirt and dust free Landrover/Rangrovers know as Toorak Tractors

I use a lot above avg power I guess with work 20 to 40kWh per day and home not that far behind - no gas- The rotten vaccine fridges get opened a lot recently for a reason or two some might know about :) My overflow vaccine fridge is at home.

Disco is in to Ritta for a service on Thursday. Love them - I know I have seen them a lot less and spent a LOT less over the last 25000 ev km traveled.

If you just want to run the fridge and freezer, some lighting and the TV then fine but on a hot night when the powers out I can see a car powering an AC system for a few hours before it runs out then someone complaining bitterly the next morning when they can’t get to the Coffee Shop for their morning Latte and smashed avo.

First world problem I guess for those that can afford it - that subject alone is worth a post of its own as the poor will get left behind and cop an unfair share of the **** sandwich like always…

May be. I did forget to add charge last Thursday so my disco when for a quick run [biggrin]

Victron multiplus inverters give me email warning for every fault, grid failure and grid restore at work. It is also has a lot of configuration options on when, where and what to do. The goodwe hybrid I had before the Victrons could do a lot as well. I can set how much to take from the batteries and how much/when to charge them and this can and does change if the Grid is off of course.

158 GIGA battery factories in EU, China, Korea and the US should make it very interesting to watch.

Post in Nuclear thread re California. Its government action 25 years ago saw Solar panel prices plummet all over the world. Batteries will take a similar trajectory and similar improvement path "Swanson's law" is about right I think. The Swanson Effect or Swanson's Law is named after Richard Swanson who founded the American solar-cell manufacturer SunPower.

He did have a vested interest of course. [thumbsupbig]

Telling your population that they can't buy an ICE powered vehicle in 13 year (as has happened in California) when there isn't a viable alternative or the power to make battery EV's workable for most of the population at an affordable price seems pretty rapid to me - 2009 wasn't that long ago, and 2035 will come up pretty quickly when there is only a fraction of a percent of the infrastructure that will be required and no way of getting to what is needed in the forecast period.

And why is it that as soon as I point out issues that will arise (From experience, not by being a keyboard warrior and looking at Faceplant articles), I get these sort of comments 'Denier' and 'EV Hater' - I AM NEITHER OF THESE THINGS and I resent the implication to be honest so if you think I'm on my high horse, I wish all the one eyed EV lovers that won't even accept the discussion about the issues that are arising from them would get off theirs as well - IMO this group are worse that the 'deniers' as you call them.

I thought the discussion here could be had without name calling but that doesn't seem to be the case unfortunately.

I'm also all ears for you to tell me how we can decarbonise the grid within the next 25 years as well - because if you know how you'll have solved all the worlds problems. Do we need to? Absolutely - can we in the timeframes being talked about - not a chance.

No issue. Just get a big generator to charge your car during peak times. [bigsmile]

I think the ban is on "New ICE" vehicles in California and we have to start somewhere, CA. has always been a leader see CAFE fuel efficiency standard which I like to think of as CA(lifornia)Fuel Efficiency standard which a lot of US states and even countries later followed, these things take longer than people think, to wit Aus. doesn't even have a fuel efficiency standard yet.

In WWII even Winston Churchill thought Britain might be invaded hence his "we shall fight them on the beaches" speech, but 5 years later they had won, and we have 25 years.

This pom is on the money I think. https://twitter.com/SquillMama/statu...nebLuQnSJsK2F0
Warning he is grumpy and unhappy about the very large power price rises!!! Swearing...
prediction of a UK revolution and riots[bigwhistle]


So many places in this discussion are interesting. Anyone assuming we can burn coal for ever or even for much longer and not impact on all of us is missing the boat. Happily I am fairly. We have been mislead that wind and solar are enough with out other real options by some hopeful but not realistic people and sadly that has deflected from a really urgent need to start the changes required that will work for all of us. Our choices are just that. the Options required to give everyone more appropriate choice is needed not beating any one up for our existing limited options.

Very very glad we live here and not in the EU/UK/Russia.... Japan is a big question as well as is China and India.

Canberra's choice to ban ICE and allow EV sales only from 2035 might be a bit funny as you can drive to NSW in a hour or less of course. We need options before that is really possible.

Noted a few million funding for Hydrogen stations on the Hume Highway "This joint initiative of the Victorian and New South Wales governments supports the development of at least 4 refuelling stations along the Hume Highway and will support approximately 25 hydrogen-powered long-haul heavy freight vehicles to adopt zero-emission technology, such as fuel cells." is still open if your keen on that. [bigwhistle] Just 25 trucks!!! Very slow start.

I have to service the Disco on Thursday. Drop it off and run home under my own steam. EV charging planned in the morning before the run is right beside a EV racing team at a UNI. Have to have look at EV racing. That is were many safety things like ABS and stability control developed of course.
