Assuming, that is, that we have any hope.
There is nothing inherent about manufacturing solar panels which
requires the sort of environmental damage we see in China (just as the paint used on toys is not
required to include lead.)

Because of the environmental hazard, polysilicon companies in the developed world recycle the compound, putting it back into the production process. But the high investment costs and time, not to mention the enormous energy consumption required for heating the substance to more than 1800 degrees Fahrenheit for the recycling, have discouraged many factories in China from doing the same. Like Luoyang Zhonggui, other solar plants in China have not installed technology to prevent pollutants from getting into the environment or have not brought those systems fully online, industry sources say.
"The recycling technology is of course being thought about, but currently it's still not mature," said Shi Jun, a former photovoltaic technology researcher at the Chinese Academy of Sciences.
Shi, chief executive of Pro-EnerTech, a start-up polysilicon research firm in Shanghai, said that there's such a severe shortage of polysilicon that the government is willing to overlook this issue for now.
"If this happened in the United States, you'd probably be arrested," he said.
