A man rides outside a laboratory building of Yingli Solar, in Baoding, Hebei province, May 5, 2014. Seven years ago, the Chinese city of Baoding launched an ambitious "low-carbon" plan using renewables like solar power to light its streets and heat residential buildings, putting it at the forefront of the country's battle to cut pollution. It has spent more than 10 years nurturing high-technology sectors, and is home to the world's biggest PV (photovoltaic) manufacturer, Yingli Solar. Renewables generate around a fifth of local GDP, many times the national average. Baoding's long-term aim is to raise the share to 50 percent. Picture taken May 5, 2014.
