In this 6-minute clip from the film DIRTY BUSINESS, Rolling Stone reporter Jeff Goodell talks about the need to not only find new forms of renewable energy, like wind or solar power, to replace coal as an energy source, but to change how we use energy to be more efficient. We meet Tom and Sean Casten, the father/son team that runs Recycled Energy Development, who are retrofitting a silicon plant in West Virginia to recycle its waste heat to provide 40% of the factory’s power, thus cutting back the plant’s greenhouse emissions, saving the company money and potentially drawing manufacturing jobs back from China. The Castens argue that through energy efficiency, we could eliminate 20% of U.S. CO2 emissions and save about a hundred billion dollars a year. Joseph Romm of the climateprogress.org blog calls the U.S. the "Saudi Arabia of wasted energy"—the amount of heat wasted in energy production in this country, he says, could power all of Japan. Less
