Lots of fuels (like petrol) are a lot more energy dense than out best batteries. If we can synthesize fuels like that just using electricity as an energy source (that can be generated from renewables) then you have a carbon free dense store of energy that can be used to power a vehicle for a long distance without refueling.

The problem with these (fuel cells etc) is that the conversation rate is inefficient, wasting a lot of energy. As we are not using 100% renewable energy this means carbon is being released still.

If we had an entirely renewable energy grid (with oversupply when sunny/windy etc) then those energy losses would not matter.

I'm going to say that if you can charge at home, then electric cars are awesome, otherwise a HFC style car might be better.

Both are going to require significant infrastructure build out, but electric chargers are much easier to install.

I'm going to say that less than 30% of houses here in the UK have a garage/carport etc (either individual or shared).

Most of the individual garages will be sized to fit an old mini, not a modern car (even a small one)

I hate using the delivery services though, they can be useless for fresh veg/meat as you can't properly pick a good cut or the right amount.

The substitutions can be awful too.

You use self scan (get your own handheld scanner) for those shops

I'm not saying that it's good, isn't that most people don't know/care, they want a new car and know that electric cars are the way things are going.

Most people are not keeping track of all this. They shop around for cars and find that, Tesla has one of the only competitive long range option in the mid price points.

I imagine that a lot of people that DO know what's going on would rather still buy one and have an electric car than buy another fossil fuel one. It's green Vs ethics... And most of their close competition seem to be the Chinese brands, so musk might actually somehow still have the ethical upper hand too....

There isn't much decent choice in a lot of the price range.

Spotify of all things used to wake my computer from sleep. I was so close to migrating away from them when they fixed it.

Windows also loves to turn itself on for updates, but then not put itself back to sleep after....

Hibernate with an SSD is pretty damn good anyway. It's not always available for some reason though?

It sounds like this is being used for day/night storage here as opposed to spot demand, so it may be using more of the charge range.

I wonder if these batteries have reduced peak power output, can they fulfil the kind of balancing that you are suggesting? I guess if they had enough it would be fine.

I'm assuming that doing full charge/discharge cycles on them daily will put more wear on them than every day driving would?

But if your buying them at scrap value and the. Still selling them as scrap after a few more years I guess it works out.
