“Estimated U.S. Energy Use in 2014.” Livermore's data shows that the transportation sector consumes 27.1 quads of energy a year (out of total national consumption of 98.3 quads). Of that, 21.4 quads are “rejected,” i.e. wasted—78.9 percent of the total transportation energy picture. One quad is a fantastic amount of energy, equal to 10

BTUs, or 252 megatons of TNT. By comparison, the most powerful nuclear bomb in the U.S. arsenal in 2015 is 1.2 megatons.

If storage were the only consideration, the cheapest, strongest shape for a single-serve beverage container would be a sphere, which would use the least material and distribute weight and pressure evenly throughout the inner surface of the can, avoiding the engineering weak points of corners and seams. But they would be a nightmare to pack in a case or carton: stacked, 26 percent of the space inside the shipping container would be dead space. (They'd also be clumsy to handle for consumers, and would be prone to rolling off tables.)

From a sustainability perspective, aluminum cans are still not “green,” as they are still single-use containers for which energy and transportation must be expended to recycle. A less wasteful option is to reuse containers.

Red mud is one of the biggest waste problems facing the mining industry, with 80 million tons of it created annually, which must be kept segregated in giant holding ponds. If let loose, red mud can render lifeless any natural environment it touches—as demonstrated by a fatal spill in Hungary that swept through farms and a village, killing 10 and injuring 120 people in 2010.

Oxygen is by far the most common element, not because of its presence as a life-giving gas in the atmosphere, but because so much more of it is chemically locked inside rocks and water, representing nearly half the earth's mass. Silicon is the next most abundant element, constituting 28 percent of the planet, and although we think of it these days as the expensive stuff of computer chips and solar cells, silicon is more commonly a principal ingredient in rocks and sand. Third-place aluminum weighs in at 8 percent of the earth's mass and is contained in nearly two hundred different kinds of rocks, common and precious alike, including sapphires, rubies, and emeralds.

             
There are only a few other common elements: iron makes up 5 percent of the earth's mass; calcium, 4 percent; potassium and sodium, 3 percent each; and magnesium, 2 percent. The ninety other naturally occurring elements combined make up less than 1 percent of the earth's mass.

Powders and salts

aluminum have been known and used for medicine and commerce for thousands of years, although no one suspected the metallic element at their heart. The ancient Greeks used one aluminum compound to sterilize and cleanse wounds; another, aluminum potassium sulfate—commonly called alum—was used for 5,000 years as a mordant to fix dyes to fabric. English wool merchants in the Middle Ages went to great lengths and expense to import the fine white powder from the Middle East because dyed wool fetched a far better price than plain wool. But the metallic element in this powder remained hidden.
This is why aluminum is sometimes referred to as the most “modern” of metals—which is to say it's the metal humanity only recently figured out how to exploit, as opposed to the ancient forging of copper, tin, silver, and iron mastered thousands of years ago, primarily to make better weapons of war.

A New Direction: Our Changing Relationship with Driving and the Implications for America's Future
, U.S. PIRG Education Fund, Spring 2013. The report cites these factors in support of the Millennial Generation's move away from the car:

       
•
  
The Millennials (people born between 1983 and 2000) are now the largest generation in the United States. By 2030, Millennials will be far and away the largest group in the peak driving age thirty-five- to fifty-four-year-old demographic, and will continue as such through 2040.

       
•
  
Young people age sixteen to thirty-four drove 23 percent fewer miles on average in 2009 than they did in 2001—a greater decline in driving than any other age group. The severe economic recession was likely responsible for some of the decline, but not all.

       
•
  
Millennials are more likely to want to live in urban and walkable neighborhoods and are more open to non-driving forms of transportation than older Americans. They are also the first generation to fully embrace mobile Internet-connected technologies, which are rapidly spawning new transportation options and shifting the way young Americans relate to one another, creating new avenues for living connected, vibrant lives that are less reliant on driving.
