I have heard that electricity comes directly from powerplants to our homes. No storage or battery of any kind. If I turn on an extra light, how does the powerplant adjust for such a small change in the demand? Does that mean every other device that is turned on and getting electricity from this powerplant gets a little less energy to compensate for my light?

Well there’s infrastructure in between all of that. Yes it starts at a power plant, but there are substations before it reaches the consumers. At the substations, are devices called regulators that react to changes in consumer demand.
