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)

What are you complaining about being removed then?

Power corrupts, but that doesn't mean that we don't need positions of power...

Have you not seen what the russia-ukraine front line looks like? It's basically a high tech ww1.

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

Their actual solution... Just stop building new solar

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.
