The funny thing is that the answer to the wests failures is literally just to be more like China. Central planning in vital sectors like infrastructure and transportation. Instead we just have a ruling class that wants to burn oil and start wars with countries that aren’t attacking us.
That would require giving up on the ultra-liberal reduced-state no-regulation orthodoxy which has put so much power in the hands of Money and money in the pockets of Politicians.
The entire top of the current Western power structures is against it, hence we're going down the route of Collapse Through Stagnation.
The crash in the cost of Renewables is taking care of that.
There are 3 main kinds of energy use in the West:
Only the first one gains from the current trend for ever cheaper electricity from Renewables which is ongoing: for example only a few years ago Gas Power Generation was cheaper than Solar, but now its now anymore.
So to fully take advantage of that trend, as much as possible of power usage in the Economy needs to be Electricity use rather than other sources of power (other renewables too are useful, but it's in electrical power generation that we are seeing the stronger and most sustained fall in costs).
What you're seeing in Electricity prices in many countries in Europe still being high is the inertia due to installed infrastructure (I bet Belgium still has lots of Gas Power Plants and buys lots of power from French Nuclear Power Plants) delaying things like fully taking advantage of, for example, very low solar panel costs. Also the installed generation industries are trying to delay the march of renewables - for example France has been for ages blocking the construction of power connection bringing cheaper power from renewables from the Iberian Peninsula to the rest of Europe because it would compete with their own sales of Power generated by their Nuclear Power Plants.
Still, for some there are ways to go around it, though depending on one's own condition - for example if you have your own house, and your car is there for at least part of the time of the day when there is daylight, getting solar panels to help charge that EV makes a lot of sense because one can feed the other directly and that power is at cost (which is basically just the cost of buying and installing the panel) rather than being the 4-times more expensive than wholesale power you get from a retail electricity supplier.
Anyways, the trend in Electricity is for it to get cheaper. The trend in Oil is for it the get more expensive (as the easier to get to reserves get depleted and harder and more costly to extract or process stuff such as tar sands gets used) and the same for Gas but slower (since there are far vaster gas reserves than oil), so it makes some sense in the mid and long term to get the biggest power consumers at home to be using Electricity.
