World’s largest solar research center — in Xian, China

Interesting for what this means:

world’s largest solar research center — in Xian, China

From Thomas Friedman's column - Have a Nice Day.

My take on it:

1. China is a source of relatively cheap Engineering.
2. Huge demand in China for solar technology due to government requirements for Clean Energy.
3. US is lagging behind in the Solar demand.
