I think that just because China has a large population and cheap electricity.

and because they can actually produce there their cheap, because arabia, have also cheap electricity and not a small population, but there are no farms there
That's what I was thinking about other day, Saudi Arabia has a really cheap electricity. How come there are no mining farms out there?
Is this something law related? Is it because they are a Muslim country or what? I wouldn't believe so, but there must be a simple explanation.
