But the view from solar panel factories is sometimes a little different.
Chinese solar panel pollution.
China is halting construction on new coal powered plants that emit the hazardous pollutants that often choke cities in a thick blanket of toxic smog.
Symbolic of an era of new energy the solar industry presents a bright and clean image to the world.
Protests last month exposed pollution problems at a manufacturing site in zhejiang province which according to industry insiders are just the tip of the iceberg.
Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants.
China s rapid economic expansion was largely fuelled by coal which lifted millions of people out of poverty but also drove up levels of air pollution.
In 2015 china became the world s largest producer of photovoltaic power narrowly surpassing germany.

Smog smothers solar energy in china 2003 2014 png on some hazy days particularly in winter china s skies are blanketed by white and gray clouds of air pollutants.
New research shows that such smog not only dims the daylight and makes the air hard to breathe but it reduces the amount of sunlight reaching china s solar panels.
Panels produced in china which relies heavily on coal for power have a larger carbon footprint than those produced in europe.
Solar panel manufacturers need electricity and thermal energy and carbon emissions from their generation can vary widely with location.
Chinese air pollution dimmed sunlight enough to impact solar panels.
