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.
