Well, mixed news as others have mentioned. Of course it is great how much solar is installed. But at least in Germany, new installation will require a “killswitch” which disconnects the system in cases where the price goes negative/the grid is overloaded. So the grid/storage cannot really handle renewables yet. On the brightside, this only applies if you are not able to dynamically adjust your system. So with a modern system you can just charge your battery or car instead.

I’d be very surprised if OneWeb ever launches on Ariane 6. It is not build for cheap LEO launches at all afaik. But maybe some ride shares, who knows.

What other power source? There is only solar and nuclear in space. And not even NASA does nuclear unless absolutely required for the mission.
