Sort the table by Renewables as a percentage of generation. There are countries with flourishing economies running with a majority of renewable power generation.

The intermittency problems for some renewables are being overcome as more solutions are invented and improved. Most new technologies have problems to overcome, so it'd be unrealistic to expect instant & perfect solutions. The speed of innovation here is impressive enough to already be delivering real world solutions which provide energy to communities and countries.

You are confusing energy with electricity. In ex, Denmark electricity is only 17% of the energy consumption.

On a global scale wind and solar only handles 1% of all energy consumption and it's not expected to move to more than 3-4% in 2040.

And no the intermittency problem is not being overcome, not even by a long shot, as it's a physical boundaries problem not technology or optimization problem.
