You can't say they aren't trying.

Continuously bashed as one of the worst polluters in California, Hollywood production houses have been working hard the last few years to reduce their environmental footprint and green up their image. According to an industry report last year, studios last year diverted some 40 million pounds — or 66 percent — of their sets and other solid waste from landfills.

Recycling, composting, carpooling, etc. were all a big part of that — but the use of renewable energy was also a major player.

Take for instance this massive portable solar array from Pure Power Distribution — called the largest in the world. According to their website, Warner Brothers has rented the unit for movies like Leonardo DiCaprio's "Inception" and an untitled Steve Carrell production. Once brought to a site, it takes little more than a few minutes to setup — and outputs some 72,000 watts of “pure sine wave power with no noise, and no emissions.”

That's enough to keep nearly a ton of CO2 out of the atmosphere every day.

Pure Power Distribution has partnered with the Environmental Media Association — so there's no doubt we'll be seeing them behind the scenes of even more Hollywood films in the future. Check out their website for more details here.
