Energy News: Explained at BurningMan.com : "This year our art theme will express the immanence of nature in our lives... The Burning Man will stand atop a structure that resembles green mountain peak. Nestled at its base, will be the Green Man Pavilion, 30,000 square feet of shaded exhibition space for the display of interactive artistic, scientific and educational models, a 'World’s Fair' of emerging technologies. ... But we will do much more than this ...we will calculate the amount of climate changing gases that are released into the air by the construction and the burning of the Man and its pedestal. This is called a carbon footprint. Then we'll sponsor projects in the outside world that will efface this imprint. Such actions might include the planting of trees or the development of non-polluting energy resources. Having played with fire, we'll take care to cleanse its atmospheric playground."
