I would think that China is going to do whatever is most profitable.  If that means more renewable energy because international markets demand eco-friendly products / infrastructure, then so be it.

this is the kind of baloney greenwashing that shows an obsession with CO2 to the detriment of the other 95% of the planetary concerns.  kind of like "let's kill all the deserts off so we can have big, unreliable CSP plants."  there is more than CO2 harming the planet, people.

So, let's not get all warm and greeny over the country that dumps incredibly toxic byproducts in SCHOOLYARDS when they manufacture PV panels, ok?

until all Western nations put Clean and Fair Trade rules into place for every company they are trading with (no poisoning, no sweatshops, etc.), countries like China will continue accelerating the rate of harm to the planet.  

poisoning kids is not acceptable "collateral damage" to making solar panels under any scenario.  I will absolutely boycott these products, and purchase from US or Japanese producers, which recycle their byproducts.  we all should.

Yes, there is a cost during the creation of the alternative energy infrastructure.  China is rushing through the 2 centuries of the Industrial Revolution in two decades!   But the end result is to get enough power in place to then build the wind-solar-hydrogen economy.   After that sacrifice is made...let the good times roll...
