Last year, China generated 834 terawatt-hours of solar power.
Which is more than the G7 countries generated, and more than the US and EU combined. In fact the only country group that generates more solar power than China is the OECD, all 38 countries of it.

It is strategic necessity for China for energy security and for their own environment. Their predominant source of electricity has been coal which they have abundant of but is polluting the air they breathe. Does anyone recall the issues they had at Beijing Olympics? They have insufficient sources of oil and gas domestically. Alternative energy sources are their best domestic source of energy.
