  1. Which is why neighbourhood batteries and a more distributed grid in general makes sense. Keep generation, storage and usage close where possible.

  2. If the payout is only payable on your death, your kids are adults now and presumably looking after themselves, and your wife has passed away, then I can't see the point of continuing to spending 25% of your pension on this product anymore. Far better to walk away, accept the loss of a payout you will never benefit from, keep the money and spend it on yourself now while you're alive.

  3. After the rain finally came a month or so ago, the earth burst forth with mallow weed which took over where I would have liked to have had a lawn, save for two years of drought. It had grown to shin-deep in thick patches, and I knew I had to cut it down. Unfortunately, my lawn mower hasn't been used for two years, either. I pulled it out of the shed, and put in some fuel, which had been in the can for two years as well. You knop already that teh mower would not start. So I had been thinking for a while that the mower had probably had it, and I done some looking around at the price of a new one - about $400. As a last resort, I tipped out the old fuel and oput in some freash stuff. I rejoiced when the mower fired up. I set about attacking one section of my yard and will knock over teh rest of it tomorrow. Eight bucks worth of fresh fuel save me a coulple of hundred bucks, abd gave me a bit of satisfaction for finally starting a job that was high on the To Do list.

  4. What is happening in the ME will give a real Impetus to EV sales. People don't want to be hung out to dry every time someone does silly things with supply.. Nev

  5. Vic Labor is destructing faster than the Libs. Two ministers have quit effective immediately, leaving not only the Cabinet, but politics entirely. And the Suburban Rail Loop might be cancelled.

  6. Manufacturing accounts for around 20% of electricity consumption. It's drop in electricity consumption, according to AI, is due to structural issues and reduction in production outputs; not efficiency gains, so that needs to be addressed - but that is outside the scope of this thread, unless you are somehow asserting the transition to renewables is inhibiting manufacturing output. Of course, one can argue that the cost of the transition has to be borne and this flows into higher input costs for manufacturers, which makes them less competitive. But, that would be an argument more that the longer term planning of our manufacturers and government was deficient as the world's largest manufacturing country, China, is going hell for leather into renewables and surely they would be having similar transition costs. Be that as it may, if we stay with relatively high fossil fuel costs or move to expensive nuclear costs, we will, by the next generation or so, have much higher input energy costs. Not to mention the increasing cost of geopolitical and civil unrest by staying with fossil fuels and further accelerating the earth heating up, drying out, and food and other resources (such as wood) becoming more and more scarce. The one saving grace on resource demand is in the western world, the birth rates are declining and in some cases, dramatically, but the rest of the world will fill that hole. Also, other environmental impacts such as ocean warming, jetstream and gulfstream disruption will have a profound impact and cost far in excess of economic costs. Algal blooms; microrganisms dying which are causing starvation up the food chain are very worrying because of the impact they will have on the ecology and life on earth - ironically which sustains human life. It looks like there will be an "I told you so" moment able to be delivered by Greta. But I digress.. The cost of not doing it is far bigger than the cost of doing it.

  7. Australia currently gets around 36% of its electrical energy from renewables & this is increasing all the time as our reliance on fossil fueled generation reduces with retiring assets and increasing wind & solar with some pumped hydro on the way. Our reliance on diesel for heavy transport has to be addressed more urgently now given global volatility and ever increasing cost.

  9. I am having a battle with an insurance company who are robbing me blind. About 45 years ago, just after moving from Sydney to Melbourne and buying a house, my sons were about to start school and my daughter was born. My wife suggested that I should get life insurance to protect her and the kids if anything happened to me. There was a company in Gippsland that offered a Private Pilot's Insurance product, as most companies steered away from PPL holders. I took out a policy which covered whole of life, ie, payable only on death. After paying premiums for over 45 years, and my kids over 40, and mortgage paid off, my wife and I decided that it was getting too expensive to keep increasing the policy in line with CPI and froze the payout at the figure at the time. However, despite a fixed payout, the premiums continued to increase. Then my wife passed away in 2022, so the beneficiaries are the kids. But the monthly premium is now 25% of my monthly pension, and I will get nothing back myself. I worked out that if I ceased paying the premiums and banked the amount with no annual increase, I would save the payout amount in 7.25 years, even less with interest. I explained this to the insurance company, saying I have only the pension as income and rely on it to live. They said they had to keep increasing the premium to pay for additional costs due to my aging. I told them that was utter bullshit as they acknowledged that the payout was frozen. They said I could cancel the policy, but I have asked them to confirm this would result in forfeiting any payout and I am waiting on their reply. I told them that while what they are doing may technically be legal, it is morally unacceptable. I said they had worse morals than an online scammer.

  11. Australia's 'burbs are overwhelmingly detached houses. Thousands of hectares of them. All with roofs which in many cases already have solar panels. Cheaper than nuclear or new gas or coal to fund neighbourhood batteries and more solar, and smart boxes on each property. Batteries could still be connected to wider grid for importing or exporting when demand changes.

  12. So windfarms in city parklands? Was in Europe recently, Quite a few in Amsterdam and could see a WTG from the London Eye. The ones in Amsterdam that I saw close were 3MW machine, so reasonably large.

  14. The real waste heat is when you have to go to obvious and visible ways of disposing of it like heated water towers. All energy ends up as heat. (Entropy) Gears lose more than chains. Torque converters create heat, Hydro drives etc. electric is way ahead. Nev

  15. Electric motors typically run at between 85% & 95% efficiency. Energy lost is mostly heat. Older AC induction motors usually run between 75% & 85%. Modern EVs convert over 77% of the energy at the wheels. The rest is lost to heat and friction. Fossil fuelled cars are very inefficient when converting the energy in the fuel to the wheels at between 12% and 30%. Again the rest is lost to heat and friction.

  16. I think Europe is seeing the consequences of climate inaction. My guess is even France will be seriously looking at solar and wind after this season.. The UK is in its 4th heatwave (I have suggested this is the new norm) Apart from the different tree species and narrow roads, it look a lot like an Aussie landscape in summer. And that means it too is becoming a tinderbox. This is the third year running.
