I=U/R , R goes to 0, I goes to infinity => U=IR= 0 times infinity, i don't get it, why 0 "wins" here? Thank you!

R goes to zero correct. So U must be zero so that current is finite. 1/0 is infinte 0/0 is finite.

If the resistance is zero then no energy is needed.

Understanding of physics is the explanation, don't get tied up multiplying and dividing zeros and infinities.
