The moronic left wants people to think that other nations use less by choice. It because those nations don't have the capability of doing such.
You are correct and the other side of the leftist cant and canard is that if the US were to sink to the point of consuming 24%, by most economic computations (ie those not based upon delusional theorems) the rest of the world would go into the GREATEST DEPRESSION.
Try running an IC engine without a functioning spark-plug, it matters not how much gas you give it, it will not run. The days when nations and economies were self-sustaning ended long before the last century started and the World is BETTER FOR IT! Idiots like this loon will ever look only upon the negatives and, like the immature baby that they are, cry for the unobtainable moon!
