Yep, overnight night. I lived in a house on a property with no mains power and my battery bank was similar except with more capacity. I was able to power my house overnight. Most days I had the solar capacity to run my house and charge my batteries. This is not a one-off there are plenty of community batteries installed and proposed. it is not just about independence from the grid. Some of these towns have unreliable power due to infrastructure (poles and wires etc) Although a diesel generator may have a lower upfront cost it is also loud smelly and carcinogenic. Benefits of community batteries Allows more rooftop solar and electric devices, such as electric vehicle chargers to be connected. They will strengthen the grid reducing the need to limit (curtail) solar exports and help customers maximise their solar investment. Helps share more solar within the local area, including to households without solar. Creates a positive impact on wholesale electricity prices that could eventually flow through to reduced electricity prices Helps to regulate voltage on the network and improves network quality in the local area. Offers a flexible alternative to traditional poles and wires investment and helps lower network costs. Access to an online information hub where the community can see how much energy was stored and used daily.

In terms of home batteries and safety, I guess it comes down to the a risk-benefit situation. Houses have been burned down by a gas leak and people have died from carbon monoxide poisoning form inadequately ventilation. I think the point is what is the track record of home batteries. Another issue is that battery chemistry is progressing fast. Sodium shows great promise especially for static use although these batteries are in some cars already. First sodium-ion battery EVs go into serial production in China Here is an interesting home "battery" that is available right now https://www.lavo.com.au/lavo-hydrogen/ This is a unit that uses excess solar to produce hydrogen and oxygen by electrolysis and then when needed recombines them in a fuel cell. I know what you are thinking hydrogen could explode. The hydrogen is stored not under pressure but within a metal hydride. The downside at this point in time is that it is more expensive than a traditional battery. I foresee a time when each house will power itself. I guess the power retailers will hate that. There are country towns that already have community batteries. One to look at is the town of Yackandandah or Yack as the locals call it. To me, these are interesting times

There is no doubt that society's appetite for electricity will increase. There are factors that will help stem the increase. As you have pointed out rooftop solar is a huge factor. In my case since I have installed solar my monitoring app shows that I have produced 25,4 MWh and I have used 14.8MWh and sent my excess 10.6MWh back to the grid. Of course, I do need the grid for night and adverse weather unless I get a battery or an EV which could also act as a battery. Basically, I with my small system produce much more than I use. Recently flying interstate and landing over the city (Adelaide) it was amazing to see how many houses and factories have panels. EVs may pose some challenges but also are a huge benefit. Overnight the demand for power drops dramatically. There is even a name for it (duck curve) EVs are an advantage when they charge overnight and with v2g technology can sell some back during peak times. This is not fiction but is starting to happen overseas and can be especially useful to fleet owners who operate 9 to 5. I was going to post some links but you can look it up yourself. It is fascinating even exciting to me at least. Data centres have been mentioned. I know many especially Google are working on this, even if only for monetary reasons. "In 2022 – for the sixth consecutive year – Google matched 100 percent of its global annual electricity consumption with purchases of renewable energy." If we need more power generation then it becomes a question of what methods we adopt. We certainly want clean electricity but it also has to be cost effective. My question is, is Nuclear the most economical method when taking into account building running and decommissioning? By the way, look up decommissioning and note the cost and time and the few power stations have been fully decommissioned. I am not totally philosophically opposed to nuclear but it must be shown that it is cheaper and cleaner. Anyone who is on board with the opposition plan must surely have doubts without those questions being answered. Other issues are, who will build them? I doubt we have the expertise here. To those who are totally onboard without knowing the answers to these questions, I would ask them to give me an example of a country similar to Australia so we can see how long it took them to build theirs and how much it cost them and if they have had any challenges. Even if we do go nuclear we will need other clean methods to use in the meantime and to support nuclear. France has been aggressively nuclear and now 70% of its power comes from reactors which means 30% comes from somewhere else. I believe I am being rational by saying I can not decide without knowing the cost, how long will it take to get them online, who will build them and how will waste and decommissioning be handled.

My last post is electricity 2010 to 2023. It shows a modest fall. This of course may not continue. I think some of the factors in this fall are increased efficiencies such as LED lighting etc. Also the enormous uptake of rooftop solar. Economic conditions may also play a part. This small decrease seems to be worldwide.

Annual electricity consumption in the NEM in Australia from financial year 2010 to 2023

Australia’s energy consumption fell 0.1% in 2021-22 to 5,762 PJ, the third successive year of decline and down 7% from the all-time peak of 6,188 PJ in 2018-19. The drop in consumption in 2021-22 was 7 PJ. https://www.energy.gov.au/energy-data/australian-energy-statistics/energy-consumption This is all energy not just electricity. I am still looking for a more clear source.

I believe energy consumption has decreased. I will have a look for the figures. I think the reason is improved efficiencies etc.

My question still stands though. What percentage of our power needs would the 6 or 7 reactors proposed for Australia contribute? Without this information how can anyone make a rational call on this?

I just read that Canada has 19 reactors which generate 15 percent of if it's power needs. What percentage will the 6 or 7 proposed here contribute?

I have not so far expressed a strong opinion and am not necessarily philosophy opposed to nuclear power. I do however need to know the cost of construction and decommissioning. I want to know who would build it. know about waste storage. When I look at recent constructions they do appear to be expensive and slow. I also need to make comparisons with other methods. I think this is fair and open-minded

My son's first EV had this arrangement - BMWI3 very practical in some respects but flawed in other ways

The change from the Julian calender to the Gregorian.

Spacey can you post an actual link. This was the figure in question. No drama though. I thought perhaps a typo

Yes quite correct, Posted in haste I meant the Earth. Certainly not 50 billion.

Billion? the universe is only 4.5 billion years old.

My last month's (actually 24 days) electricity bill was $46.53 however we are in credit. This bill will cost me $16.38 will cost. All electric home. Why is it so low? It helps that we live in a quite small place and we try to schedule as much use during the middle of the day.

I have read various things about supplies of minerals for modern tech. I do think it is an important issue. Lithium doesn't seem to be a problem. I think I have read more about copper. Recycling will have to be a major part if we are to continue to advance electronic technology. Oil is not a finite resource and can only be burnt once although things like plastic of course can be recycled in some cases. If the minerals required in our electronic devices become harder to source then the price will go up, This also applies to oil.

EVs are generally more expensive to insure. The charging network needs to expand EVs generally have a higher sticker price Longer trips need more planning Rushing out and buying a new EV does not make sense for everyone at this stage 100% EV is many many years away is at all. We are still at the enthusiast stage of adoption These are all things I believe I have mentioned in my posts.

I would humbly suggest that whether or not you agree with me I do attempt to support my posts with multiple sources. I get it that you think anyone who is enthusiastic about new technology must be some type of simpleton. i get that you are uncomfortable with this new technology. You believe that you know this technology is bound to fail. Sometimes you just have to wait for the history to play out. If we dumbfuf*cks who stupidly believe that electric motors are much m, more efficient than piston motors are wrong then you will get to enjoy the "I told you so: moment. The most ambitious goals for EV adoption are 9 years away. How far has technology come in the last 9 years? The change to EVs is not particularly fast. I drove an early leaf 2014 that is now 10 years old. If the most ambitious plans for EVs come true then in 2035 all NEW cars will be EV. My old Ford Focus is 17 years old and still viable for a few more years. 17 years from 2035 is 2053. As long as petrol is available you will still be able to drive a petrol car (if you can afford it) I have a friend who occasionally drives his 1987 Ford. Sorry, but I think your constant hysterical griping is a bit sad.

OK as a rational person, I like to delve into the evidence. The video you posted OME states that public charging is slow expensive and inconvenient the author of the video avoids providing evidence. According to statistics from 2021, 10.3% live in apartments. So if this is a problem then it is a 10% problem. I actually live in a strata title property and I am on the committee and I have some understanding of the issues. This guy is massively exaggerating. I could post some videos of fact-checking of this guy, should I do that??? My son charges his EV overnight for 10 cents a kilowatt in his garage under his house. Charging overnight is GOOD for the grid (you probably don't know why). He does this twice a week which is all that is required for his normal driving. He lives his life happily but you seem to think his life must be hell. If you think my son charging his EV under his house is foolish I would be happy to pass that on to him and because he is scientifically literate and smarter certainly to me, I am sure he would act on your logical concerns. If I had thought buying an EV was right at this point in time,I would certainly buy an EV. I would mainly charge it from home for free. This would make sense, wouldn't it??? Getting back to Mr crusty old conservative's video. Is public charging slow???? Ask yourself why he does he not get into real-world charging times. What is the expense and charging times at public networks? This surely is key to your (hysterical) objectives)

"EV owners urged not to charge EVs in the garage." A search for this turns up one article from the Sun that I did not even bother reading and an advisory for owners of Chevy Volts which I believe had a recall because of faulty batteries and some fires. Of course, this kind of thing doesn't ever happen with petrol cars oh wait yes it does. Hyundai and Kia ask owners to park outside due to risk of fire This though does not seem to be as alarming as those nasty new-fangled electric contraptions. From memory, he talks about the coming crisis of increased insurance premiums for charging facilities in apartment blocks. OK if this is true then people in apartments will have a disincentive to buy EVs and this will play into the market. NBo need for a hysterical whiney warning. At the end of the day insurance premiums will be determined by real world events. My son charges his EV in his garage which is under his house. I suppose you think he is a f****** idiot. I am not sure where @kgwilson parks his car but maybe you think get is a f******* idiot also. OME you said this in an earlier post: "Many of us are seeing this and lamenting another old skill being tossed onto the discarded arts heap. Many of us see the logic in stopping the rampant use of a diminishing resource, but the same "many" are getting "change fatigue" that they have been subjected to for close on 75 years. Let the upcoming generations work at making the use of liquid fuels a page in the history of Mankind. Just don't pressure older generations to turn the page so quickly. Some of us like to bask in the warmth of the wordsmith." Look I think this is your real issue

Yep, not very practical for a lot of applications. Good vehicle for what we used it for. I had a long chat to the driver/owner. The trip from Te Anua to Milford and back is 240 km of hilly terrain and he drives it 5 days a week most weeks. The economics make it an obvious choice.
