If electricity were cheaper you might turn the lights higher instead of balancing cost vs. comfort, wouldn't use the eco-mode on the dishwasher that occasionally results in dirty dishes, would probably not think twice about washing clothes at 30 °C instead of 40 °C, maybe use a dryer instead of clothes racks blocking the living room for a day, use the more comfortable tankless warm water heater, properly preheating the oven giving you the results you want etc. pp. ... the list is endless.

But electricity often costs upwards of 30 cents/kWh nowadays, so you avoid doing all those comfy things. 'cause they're expensive.
