The heating effect of electricity can be good or bad. If it is in the form of losses in electrical equipment or wiring, then it is bad - just as waste of energy. On the other hand if it is used in an appliance such as a toaster, it is good.
However when it comes to heating buildings, just using electric heating is expensive and wasteful. It’s much better to use a heat pump which can move 3 - 5 times as much heat as it uses. For cooking, old resistive heating elements are also inefficient, newer induction heating heats the pots directly.
