Both cheap and renewable. Aluminum was at one time priced a thousand times higher than gold for even an ounce. There were many years going into World War 2 of an aluminum shortage but these fears proved totally unfounded. Today there is actually a glut of Aluminum so the cheap energy is a market necessity as the demand for Aluminum ingots simply is not there as it was during World War 2. Steel remains the dominant metal for production as it is far more malleable and far less energy intensive to create...and thus far cheaper. Also steel is 100% recyclable leaving Aluminum stuck in the soda pop
