It depends on what you mean by "harming". But to answer your question, yeah, most of them. I've been preparing my home to switch to time of use energy pricing, where power is less expensive at night when there's lower demand. It's pretty painless to put things on timers or set schedules in configuration. The trivial cost of setting this up will pay for itself within about two months. Deferring workloads for when it's sunny is almost the exact opposite: using more power during the day rather than at night. That's probably better for most consumers, since people tend to use more power when they're awake by default.
