Hey US... Belgium here. Solar panels everywhere. Sunny and windy? You het payed to consume electricity. Digital meters are rolled out everywhere, incentives are organized to install home batteries, ...
The transition is challenging, traditionally we Belgians nag about it, as we definitely do not want to be great. But that does not stop us.
Went to the town hall last week. They did an info session about home batteries. The rules relaxed recently. Dude told us that Germany is actually ahead of us.
Germany here: I severely doubt that Germany is ahead of you there. E.g. we don't get paid to consume electricity but instead have to pay a higher price because the producers of solar and wind energy get paid for the electricity they cannot sell, due to lacking demand but also due to lacking power line capacity from the north where most of the wind turbines are to the south where most of the industry is located.
Most of us also don't have the digital meters that would be required for being paid, because until recently it cost an arm and a leg to get them installed. The last government put a stop on that practice.
There are a lot of solar panels on single family houses here, but very few on larger buildings, e.g. factories, warehouses, office buildings or apartment buildings, or over parking lots (there is apparently a law in France that they have to build solar panels over new parking lots).
We are getting there, though. I just hope that our new government doesn't step on the brakes (again). They have already started pouring money into building many new gas power plants though. Fun fact: When the previous government wanted to have (fewer) gas power plants built to stabilize the power grid, the then opposition CDU party was complaining about that.
