While your bees are alive and your wallet is online, your bees will attempt to produce a new hivemined block every time they observe a new incoming proof-of-work block; hivemined blocks must always follow proof-of-work blocks. This mining attempt takes only a fraction of a second even for large hives, and shouldn't cause any lag or lock-up of your computer. Energy usage is negligible.
