It's already happening. IBM has announced its China Cloud with data center floor space ranging from 330,000 square meters to 620,000 and employing between 60,000 and 80,000 people.
Every data center has practical and physical requirements to build and operate. Today, the infrastructures that we use are often inadequate, and next generation data centers need strong capital investment, good local planning process for building permissions, redundant power supplies (and even power stations) and access to quality human resources.
The Chinese government already knows that it has a power shortage today, and it's already taking steps to massively invest in alternative power generation with nuclear energy alone exceeding a planned 70 gigawatts.
China is also building out a new electricity grid that will be more efficient, more reliable and more capable than those of America or Europe. If only because it is using newer technology, China will have a significant edge in power in the next decade while Europe and America will still be debating what power policy to have.
