These protests need to spread to every country. Solar is the future no matter what anyone says, panels on every roof in the eu would mean there was an abundance of electricity possibly double or even triple what is used right now.
There are just too many examples of where solar has been more successful than even the developers have anticipated.

Maybe in 15 or 20 years when/if materials science has figured a way to store this stuff. As it currently is, not only is solar ineffective in most geographies, but the carbon footprint of panels and batteries is faaaaarr from carbon neutral, and the effort it would take to scale it up to every green's wet dream is unsustainable.

Batteries will pretty much never be the way to go, but we've had the technology to store energy en-mass for nearly a century.
Store it as hydro. During the day, use the surplus solar power to pump water into a reservoir. At night, when the solar wanes, begin emptying the reservoir and generating hydro power.

There are a lot of ways to store energy we're just not sticking out neck out to build the infrastructure

We should do that but it isn't optimal for everywhere. For instance, lack of mountains with areas you are willing to flood. That said, there are other ways to store energy for nighttime.

Climate change is also a risk factor since hydro of course depends on rainfall, which is going to be changing over this century.

Solar cells last more than 20 years and definitely are net negative on carbon multiple times on that time scale. Also, energy use is at a maximum when the sun is up. Something about people being awake.

Solar energy is intermittent.
