If you ask “what has been the most important invention of the past 100, 150 years?” it’s been the synthesis of ammonia. If we could not synthesize ammonia by taking nitrogen from the air, hydrogen from natural gas and pressing them together in the Haber-Bosch cycle… if we could not do this to make nitrogen fertilizers, we could not grow enough food for about 40% of people. So you are talking about something like three billion people. In existential terms, that is the most important invention.

That's why he's Bill Gates, and we aren't. © 2013 Stephen Yuen
People think that we are getting better because we are dematerializing. Look at your iPhone. A perfect example of dematerialization. Before that you would need, what? An alarm clock. A telephone. A camera. A compass and a map. Now you don’t need any of these things — you just need one cellphone. So instead of having the mass of all these things like before, you dematerialize....
Many things are dematerializing, but they are dematerializing per unit. Yet we are selling many more units, so in total terms, global consumption is vastly increasing. This is like efficient energy consumption. We increase the efficiency of energy consumption, but have three televisions instead of one. Per refrigerator, per television, per car, the consumption is down. But overall, the consumption is up. [snip]
What would be the reason to rush into renewables? Global warming. But, China will burn every bit of coal it can lay its hands on. So whatever you do in the US or Germany, it’s irrelevant because China will wipe it out in a matter of weeks or months.
