>Because of the manufacturing process, solar power creates more greenhouse gas pollution than coal or natural gas per watt produced
The West faces a conundrum as it installs panels on small rooftops and in sprawling desert arrays: Most of them are produced with energy from carbon-dioxide-belching, coal-burning plants in China.

Concerns are mounting in the U.S. and Europe that the solar industry’s reliance on Chinese coal will create a big increase in emissions in the coming years as manufacturers rapidly scale up production of solar panels to meet demand. That would make the solar industry one of the world’s most prolific polluters, analysts say, undermining some of the emissions reductions achieved from widespread adoption.

Director Michael Moore's "Planet of the Humans" argues that many green energy solutions rely heavily on coal-burning power plants to function.
