and it is trivial to have cars charge at times when it is most convenient to the grid.
What does matter for users is having cars charged when they need it.
EV are a dead end. Batteries are polluting to produce, require rare materials to produce, are hardly recyclable. let's also wait a couple of years to have more experience on how batteries behave when they get older. Also, the infrastructure you need to build to produce, manage, transport and provide the electricity for EV will generate a lot of CO2 (concrete making generates a lot of CO2 for instance).
That's 18GW*24h = 432GWh that we could have produced
If ifs and ands were pots and pans there'd be no work for tinkers' hands.
Anyway, even if whole Europe becomes carbon-neutral in 2030, CO2 in atmosphere will continue to grow because of India and China.
Becoming carbon neutral is a good thing, BUT:
- it won't be a solution to global warming
- There's no point of doing this if you produce a lot more of CO2 to produce new stuff to replace the old one.
My solutions:
- Hydrogen for vehicles (cars, trucks, trains) and for heating: hydrogen is a far better way to store energy than batteries. There are also incoming solutions to store hydrogen easily, even in a household.
- Give a high kick to CO2 storage, because we have urgently to find solutions for CO2 produced outside of Europe, which is by far the majority. In 2020, Europe accounted for 11,2% of the CO2 produced worldwide.
If you want to solve a problem, addressing 10% of it won't work.
