Surely, at some point in the near future, they'll be producing solar panels using solar energy?

> China builds solar panels using electricity produced by burning coal.

Source? From everything I can find, at this moment China has around half of the generation coming from clean/renewable sources.

Per-country yes China is #1, but per-capita, oil producing countries are most of the top 10 (with island nation Palau #1, inefficient transport skewed by low population).

For goods we consume, though.

China is also one of the top two countries by population. The other is India, at almost exactly the same number of 1.4bn.
