All we'll need is enough cars plugged in for the couple weeks a year when there's hot as **** days or the days with **** all sun and wind in winter when it's cold. Both scenarios, the humans and cars should be home heating/cooling the house. All the rest is whatever, the day to day is easy. Just got to cover the edge case days.

i made $400 credit during 3 months of winter with amber. Last year I spent $700 in the same period…do to electric heating.
I left amber when my system couldn’t curtail the negative prices… that issue is now fixed so no more negative prices.
Im back with Amber and $92 in credit in 16 days.

sure if you think of energy as some "pump and dump" ponzi share scheme. but if one takes a step back and acts in good faith to deliver lowest cost energy for society, you wouldn't think like this.
and free? do you really believe energy is free? who do you feel ultimately pays for "free energy"?
The alternative is mass transit. The alternative is reducing energy consumption to a bare minimumIt is hilarious that renewables are apparently not a viable option (now - ie. not forever) because you need to add the emissions of fossil fuels.
But the alternative is to use all fossil fuels.
It's great we've got viable electric vehicles, we should use them for specific use cases. Moving around a single(few) person in a 2 ton steel box was never a great use of resources and is unsustainable for the entire population.
No one has ever produced a solar panel, wind turbine, or modern battery without heavy use of fossil fuels; this is a concern. Steel, concrete, plastic, and fertiliser can't be produced at scale in the current economic environment without fossil fuels.
Without wholesale change of economic principals, city design, and human culture in general all this stuff is pissing in the wind

FFS…. Let’s say you have a fully charged EV sitting in the drive way.
You are on a TOU tariff paying 50c during peak…. You can pay that or use you car battery for a few hours for cooking etc using 10% of the battery until the peak rates are over. Hmmmm to pay or not to pay!!!
Is this concept to hard for you to understand?

Why? Im using more electricity now than I ever have and plan on increasing my usage by double.
There is so much wasted solar generation that can be utilised.
https://en.wikipedia.org/wiki/Laws_of_thermodynamics
Wasted? So you've overdone generation and underdone storage. That energy would go into the grid that someone else could use for bare necessities no?

The entire point of renewables is to overdo generation, by about 200%, because the sun dont shine everyday.
Solar still works when it’s cloudy.. yesterday was completely overcast and I still produced enough to charge my battery and export some.
I am limited to 5kwh export… I can easily export around 8-9 on average an hour but my system has to wind down.
And yes I plan on more storage … an EV
Yeh and their isn't enough of the metals required in the planet for the whole world to do this(at current demand). it's a solution for you, not the planet
I'd guess you're limited on export because the grid can't absorb it on sunny days, which drives price gouging in peak periods without renewables available. Again a solution for you, not for say renters or apartment dwellers.
Without energy rationing and active shut down of fossil fuels it's pissing in the wind. A neoliberal solution to a global commons problem; that is to say, it's not

I think we will be fine…
It took 68 years to get to 1 terrawatt of solar … 2 years to double it.
It took 68 years for the world to reach 1 terawatt of solar PV capacity. It took just two years to double it | RenewEconomy
Global solar PV capacity has reached 2 terawatts, and is forecast to quadruple by 2030.

Yeh we're not fine, energy demand keeps going up and humans have never willingly given up a sourceI think we will be fine…
It took 68 years to get to 1 terrawatt of solar … 2 years to double it.

Throw in jeavons paradox with regards to efficiency and it's going to require some heavy handed policy to get anything done.

Yes this is why renewables and storage is so important … it’s reducing net energy but producing more electricity.
Sodium batteries coming
.And I can’t see us running out of silicon for solar panels
Silicon is the second most abundant material on Earth, after oxygen.
If you had a fixed battery , you would charge it during the day, then use it during the peak, and as far into the night as feasible.
If you use your car during the day, you would use the battery during the peak, and charge it with coal after the peak is over.
The object is to reduce CO2 emission. Your object is to find a way to scam cheap electricity for yourself.
No, you charge it the next time there is an excess of renewables in the grid.
If that doesn't happen in time then you use a reserve source of energy - currently gas but hopefully something else that is cleaner in the future. Or you walk. Or you work from home.
What you are proposing is that at a time of drought you fill the dams with tap water. It really is not that hard to understand.
Tiny roof top solar is competing "with a commercial scale .... system" so why not for batteries?
And this way consumers pay for the batteries, not the state, not the power companies, which is precisely what has happened with roof top solar - the consumer has paid for the plant.
It is not going to work for everyone, people doing extensive highway driving are not going to be part of this system as they will be using their batteries almost solely on driving, or using hybrid/petrol vehicles.
But in one of the the most highly urbanised nations on earth where the average commute is 15km or less and the average car trip is much lower than that there could be an awful lot of big batteries sitting around doing bugger all.
Car batteries are roughly 5 times the size of a Tesla power wall. They are big batteries.
Again, you are applying fossil fuel emissions to producing metals for renewables. The whole point is to remove fossil fuel emissions.
How much CO2 when those metals are produced by renewables?
You could sell 50% to the grid and still have enough to drive typical daily commutes for 3-4 days.
Nuclear really is SFA

Do you drive a car from Sunset to sunrise?
The biggest reduction to CO2 will be when we reduce peak usage at peak times.
So the spike that occurs when everyone comes home to cook etc.. if we can reduce grid usage at these times we can kill the need for coal. Because coal at the moment is basically running for those times.
The idea that people can charge for relatively cheap at work and bring the power home isn’t that big of a concept.

And that’s the challenge
Ie silicon produced in Australia requires chopping down old growth forest in South America, transporting by sea (bunker oil), 3,000 degrees in a submerged arc furnace, ground to fines releasing 12t of CO2 plus transport CO2
This is then shipped to china and converted to silane using 100kwh of energy per kilogram and precipitated to produce poly silicon
the poly is heated to over 1,200 degrees (more energy) into a puller to produce mono
This example highlights the challenge but also the opportunity.
One of the products I manufacture eliminates carbon in the process of silicon and reduces the temp from 3,000 to 500. We produce this for anodes in batteries in china and a German auto manufacturer.
Then using this same feedstock, produce silane at room temp with no further energy and seek to commercialise next year for semiconductors and batteries.
This highlights it is not impossible but this was a low hanging fruit. Other metals like aluminium, rare earths, lithium and even iron are much harder.
But again if it was easy, everyone would do it

The difference is control systems
The batteries themselves are modular but to optimise for energy purchase, energy sale relies upon market data and weather forecasts. The other is useful life optimisation.
This is not impossible but costly at small scale.
Further amortisation of a whole car over a shorter battery life and losing warranty adds to costs.
Then servicing (optimisation of control system) and repairs (even under warranty which is not free but a prepaid benefit) is more costly in a decentralised system.
