Generators
In this movie, I show how spinning a coil of wire in a magnetic field causes the flow of electrons. The energy of those electrons is expended in the light bulbs, so to light them, I have to do more work when there's bulbs attached. Ultimately the power I put in is what's converted to electricity, so the more load there is, the more power I need. This is why generators are sold rated in Watts. If you want your fridge, heater, and electric oven to be powered during a power outage, that is going to require the ability to produce a lot of joules/second (watts) and require a large engine.
