You’re mixing up two values here. Switzerland imports less than 10% of its electricity, the number you’re probably referring to is the total of “Energieträgern”, so oil, oal, gasoline, etc.

Maybe, but at least 4 people in the video have lost their jobs over this, so it has at least some consequences.
