The transition

Possibly, but I only go swimming when the wind isnt blowing

Weve got loads of interconnects as well, the French supply us with electricty from their superb nuclear grid
 
I tried that line on my wife. She wasn't impressed.

We don't have AC and the whole house is a single zone, so not much upside to a smart thermostat for us vs a simple programmable one.
We don't have A/C either, but I do have a non-utility controlled smart thermostat. It allows us to control the heater through Alexa voice commands and also to change the settings when we are away from the house.
 
Lipo House batteries: Here they cost over 10 grand, that's a lot of electricity consumption!
4 May 2026 — Residential solar batteries usually cost between $800–$1,300 per usable kWh installed.
So say $1000 per kWh.

One kWh of power from the grid down here in QLD costs about 33 cents on a flat rate but I have variables, Peak, off peak, and shoulder. The peak is 4pm till 8pm, the off peak from 10pm till 7am and the shoulder is basically through the day when my solar is running and that bit late at night. During the peak I don't run the oven or the A/C units so my usage costs are minimal, $22 for the last quarter. My last bill had a combined total grid draw of $96 for the quarter, 3 months, and that equates to just under $400 a year. That's the magic of Solar, it heats the H/W for free, runs the Washer and dishwasher and Vacuum cleaner and all the A/C units on the hot days.

So how long does a house battery last? 10 years? In your dreams. Perhaps 8 if it's full of good cells. It's constantly getting cycled remember. So $400x8 years = $3200. Get a 3kWh capacity one? Really pushing the margins, doable, but why bother with the power as cheap as it is. If you have a house with teenagers and a trophy wife you might make it work, with a 10 or 12 thousand dollar unit. The thing is, the future to ME is not about finding ways to maintain or Increase my consumption, quite the opposite. Residential solar is cheap here and makes sense but big lipo battery banks don't make sense, either from an economic standpoint or from an ecological one. It's not just $10 grand spent for a decade of overnight excess consumption, it's 5 grand spent mining the earth with diesel machines to make them too.

We need to Power Down a bit. Freeze the grids at the current levels and think about shrinking them in the years to come? Well no one wants that do they? GB has tons of wind and solar but it still gets 30% of its electricity from Gas, a fossil fuel that won't last forever. 50% of their power is from Gas, Imports, and Biomass, burning wood pellets, made from American forests and shipped over, "CARBON". Might as well just burn coal 🤨

If it wrote a song the refrain would include the phrase Alexa turn it up, Alexa turn it up, Alexa turn it up. The song would end with Alexa play it again.

a flywheel never wears out aside from bearing replacement.

electricity is like water,we think we have an abundance till we do not.

Well, we do discuss the set temps. 😁

Smart thermostats are very popular around here with all of the seasonal housing. So are wifi cameras.

They constantly pantomime net zero, its long descended into a cultural class war, if you question it you are not educated, or you have shares in oil companies or you hate your grandchildren.

Meanwhile they are just cosplaying , when Greta turned on them for yabba, yabba, all you do is talk, they dropped her like a stone, all the photo ops with her ended overnight, she was effectively banned from COP in London and did her speeches in the park without a politician in sight.

The grids are creaking now and they are on TV talking of 1.5mw car charging, heat pumps for everyone, all cooking to be electrical, all manufacturing.

And still co2 just marches on, its rising faster than ever, fossil is still rising and data centres are ripping through the tiny efforts we make so they can monitor our every breath and flood our senses with fakery and deceit.

When 5G came out the tin hatters screamed cancer, no it was built from the ground up to monitor us first, phone calls second, every modern car in the US sends 2.5gb of data a day back to number crunching data centres that sell it to everyone with a tenner in their pocket , Tesla employees were caught sharing naked footage of owners taken by the cars cameras.

It is completely and utterly out of control, god himself would be envious of its omnipotence and everyone just shrugs..someone ,somewhere has to pull the plug, make the choice between panoptica or humanity.
We are right on the teetering edge of becoming the Borg.

Well,the "Borg" adapt-we become complacent( the gap grew larger as we slept-hows it go[" to whit,to whit the cuckoo call,while greasy Joan doth keel the pot]? Friends less face it what the Cuckoos rob the wannabees enable( this freakin useless software,they had me shut up for almost 2 yrs on a bs charge( while others skated) I lost out and cannot see the use of trying to catch up to that which eludes me at the speed of electrons zipping through the mind of the "Prince of Power in the air"

I do agree that a lot of it comes down to people who are poorly informed or economic self-interest. Can't say anything about your grandchildren, though.

There is also a lot of vicious disinformation that a lot of people naively think is correct. At the same time technology is changing with extreme rapidity and so even an argument that was "correct" five years ago is about as relevant as the Gallic Wars. And even less relevant to the economics of five years from now.

Change, even change for the better, is very had for most people.
 
Well, the cost of "$800-$1300" is typical installed cost. Replacing just the batteries is usually less than half that.

Nearly all residential solar batteries sold in the states in 2026 have ten year warranties. Which tells me that if the companies want to stay in business that the average usable lifespan is quite a bit longer than that.

Given the cost curve that large batteries are on (and likely to stay on for some decades) I think it is a safe bet that replacing batteries ten years or more from now will be considerably less expensive than replacement costs today. You can find surplus storage batteries for $100 per kwh today (if you know where to look) and I think it is reasonable to expect that in 2036 that will be approximately the going rate.

At the same time installation costs won't go down as much if at all. We're already seeing that with solar installs where the electrician's hours are a far bigger part of the bill than the panels and the inverter.

Grid energy storage and home energy storage batteries are usually lithium iron phosphate, which have much better lifetime characteristics than other lithium battery chemistries. 3000-10000 cycles is a pretty common rated lifespan. They have a lower energy density, but that doesn't really matter when its sitting on a concrete pad or attached to a wall. Like most car batteries, they are downrated in capacity to keep the battery in that 30-70% charge range during normal use to prolong their lifespan.
 
They are becoming stupidly cheap now, they just need to introduce safe installation practice, its like the wild west at the moment.
Installers fitting them in lofts in terraced houses!

What would the nirvana be?
Solar roof , battery, ev with sharing capability, off peak tariffs, heat pump.
The economics are irrelevent, the government will tax you to make up the difference.

If grid connection and home set up are costing the same, would you bother to install?

If the batteries can supply me in a power outage, there is an advantage.

I have not checked, because I don't care (I like my trees shading my house). I've asked those around me with solar if they have batteries also. None do; not an option with installers around here.
 
For most people it just comes down to the economics of it. It costs X to install a system, which will save Y a month. Whats the timeframe where the monthly savings covers the install cost? My experience (as a residential architect) is its somewhere in the 6-9 year range at todays costs and electric rates where I work. My experience with custom homes is most clients at least want it considered when the house is being designed. Making sure there are some south facing roof planes that could handle a few dozen panels. The costs keep coming down and that payoff time keeps decreasing.

Batteries are much more situational as to where they make sense. If the grid allows you to get a credit for excess power generated during the day to offset use at night it probably doesn't. Especially if you live in an area without frequent outages. I don't think many clients do them, at least where I am, since Dominion does credit excess use and the grid is generally pretty reliable. More rural clients that do worry about longer outages are still doing propane generators. More cost effective for occasional 2-3 day outages. Battery banks that can supply an entire house for days during an outage (even with solar) are pretty pricey.
 
Nobody has solar in my community. Lots of snow in the winter, lots of tall pine trees, and steeply pitched roofs aren't very conducive to installing solar panels. That and more than half the homes are vacant most of the time because they are second homes. Many of the full timers, like us, have home standby generators though because the power goes out all the time.
