I've done a similar mental experiment with oil. The US consumes about 20 million barrels of oil per day. Here is a useful visualization: imagine a (US) football stadium from the air with a huge black cube floating above like something from a sci-fi movie. The cube is about 50% larger on a side than the distance between goal lines. That cube of oil is about how much the US burns in a day.
