We grow up in a world in which it seems like we already know the answers to all of the questions, like we have already arrived at our destination. That's not true, and Things Can Be Different. This blog post describes an unanswered question about electricity and makes clear our current inadequacy in trying to grapple with it.<p>> Storage is everywhere. Your gas tank stores fuel for your car. Your fridge and the supermarket store food. Your bank and wallet store money. Dams and water towers store water. Your computer stores photos, documents, and other data. Grocery stores, and other retail stores, store merchandise waiting for consumers.<p>> Imagine a world without storage. You’d have to glean food directly from the fields. You’d drink from the stream. Your car would need a hose running all the way to an oil field. We depend on storage for daily life in the modern world.<p>> And yet, the electric power grid has no storage. For over 100 years, the grid generates power for immediate consumption. Any excess is lost, and any shortage results in a brownout.
