That's going to take a lot of power in the form of electricity. This is why the Chinese Government is today hoarding copper. Copper is needed to build up your electrical grid. In the book "Good as Gold: How to Profit from the Coming Boom in Cooper" this is clearly explained. If you are a serious investor it's a must read. You'll never look at a penny the same way again.
