    The Grey Nomads and the camping fraternaty has gotten behind solar and battery power in a Big way over the last few years simply because it is a cheaper and a more reliable system than gensets were, They have also become "Smarter" and less "Wasteful" at how they use this power.
    Maybe everyone else needs to have a good hard look at how they can use Less power at home and be "Smarter" and less "Wasteful" Then maybe they would be more comfortable with the idea of relying solely on renewables

    Ah, there is some much bull**** in this thread that I hope it dies where it is.
    Norway subsidises EVs so much that it is much cheaper to own an EV than an ICE car.
    Yet 70% of EV owners also own an ICE car.

    No country has exceeded 20% renewable, besides Norway with extensive Hydro, but little wind or solar. Germany has not met it's own renewable targets for 5 years and are buying lots of BROWN coal energy from Poland. They will of course buy gas from Russia one day, and what a great idea that is.

    Teslas are on average the fifth car in the USA, in other words a virtue signal.

    On the hot Thursday a couple of weeks ago , 90% of power in SA was produced by Gas and Diesel with wind at 5% and solar and other at 5%, plus of course the BROWN coal power from Victoria. Really clean that. Wind power reduced to about 14% of capacity Australia wide at 2.30PM on that day according to the AMEO site.

    We will not know what the penetration of EVs in Australia will be for a couple of years , however in Ontario sales of EVs virtually stopped when subsidies were removed.
    Dream on .
    Regards Philip A

    Excellent example Trout...especially in terms of vehicle owners embracing renewable energy. Our nomadic population is on the rise that’s for sure and in addition to the benefits for the users, it’s so much more peaceful around campsites these days without generators! ...it’s become really noticeable over my 30 years as a nomadic camper. I’ve used solar and batteries for years. Looking forward to EV’s charging constantly and solar skinned vehicles!

    Agree also at home. Some places like Tasmania are 100% renewable / hydro already, but solar is more cost efficient over long term for many especially off grid. Other places like SA have wind and big battery power coming online.

    Switching off lights at home and using more efficient appliances is easy, but it needs a big campaign in cities!

    It all helps.

    Thanks Philip, you’re just highlighting how far there is to go and how important it is to get on board.

    Google Ted Talk and David McKay...I cant link it on my network.

    It's all good in theory until the facts are raised.

    No where in PhillipA's post did he say he wasn't on board - this is what really grinds my gears with conversations like this - he is spot on with his assessment but based on that you think he doesn't like EV's or solar? I agree with everything he says because when you look at the facts, that's exactly where we are. I've had this out to a much larger extent in CA where this is being discussed as well. Does that mean I hate renewables? No - I think they need to be built faster in fact and much more effort and time needs to be spent on this, but the facts still remain that renewables contribute very little to the grid overall. It is one thing to say '50% of the nameplate capacity of Victorias grid is renewables' but because the output can't be relied on, this figure warps what is actually happening. The very hot day Vic got a couple of weeks back saw wind providing less than 4% of its capacity - because it was hot and not windy.

    I hate coal power as much as anyone but as I understand what is going on (I work in the industry - both supply and distribution) and know we are stuck with it for decades yet because renewable power is still in such short supply overall. If for example we say Vic needs 10GW of power (It's actually more than this, but the number works for what I'm trying to explain here), there's no use building 10GW of renewables and calling it job done - we would need to build around 100GW of renewables - with around 70GWH of storage capacity to even come close. Vic currently has around 6GW of installed renewables - based on nameplate this sounds impressive in a few years we will have 50% nameplate capacity - but this will only give us around 20% of our power tops, a lot less on bad days.

    See the problem here? What do we do when the coal stations are all shot? No one want to build a new one, no one wants to build nuclear but in around 10 years we'll be absolutely screwed if nothing is done about filling the gap while we build enough renewables to keep the lights on.

    So, I believe in climate change, I'm pro EV, pro renewable, anti coal - but I get tarred with with the 'Your the problem' brush all the time because as an Engineer working in the field we are discussing here, I understand the limitations and what is required, not just all the fluffy warm stuff we here so much BS about...

    Rant over, no having a go at you personally Zeros, but I get this sort of reaction a lot from people when I point out the flaws in the current hive mentality on this subject.

    Yes which is why I thanked PhilipA’s post. Some of the facts are true and remind us of the long road ahead.

    But honestly I reckon you’re reading more into my post than was intended. If anything gets my goat, it’s the confrontational tone (which somehow seems to be acceptable?). The aggressive use of “BS” and “Dream on” do nothing to foster a civilised discussion.

    Expressing a point of view is not a ‘rant’ or ‘preaching’ just because someone disagrees with it. It would be easy to all PhilipA’s post a rant, given the language used.

    Perhaps the frustration is equal on both sides of the discussion.
