How can a load average of 0.00 exist?

I understand that the load balance is a way of measuring how busy the CPU is. However, I don't understand how a load average of 0.00 can exist. Doesn't the kernel always run? Doesn't that take part of the CPU load?

non-interactive version of HTOP?

I'd like to periodically get snapshot of per-core utilization to save to file, basically same information as htop. However, htop is interactive so it's not friendly to scripting, is there an alternative way of getting this information?
