>A lesson Europe could learn.
We've learned that lesson. Not to toot our own horn too much but we to a large extent kickstarted the thing in Germany with very little reward for it. 50% of Europe's energy produced is now reneables[1]. China's progress is incredibly impressive, but they are also the largest consumer of middle eastern oil in the world. Not really to their own fault, countries are going to be dependent on oil for a long time to come. (it's used in many more things than energy production)
