The airwaves have recently been filled with advertisements heralding a plethora of clean energy technologies. GE promoted its smart grid technologies in a Wizard of Oz-themed Super Bowl ad. Vestas, the largest wind turbine manufacturer in the world, has branded itself No. 1 in Modern Energy. Various groups have designed commercials touting the potential of "clean coal," including a GE ad featuring models-turned-miners (tagline: "Harnessing the power of coal is looking more beautiful every day."). And environmental groups have struck back against the branding of coal as "clean" with satirical advertisements (tagline: "Clean coal harnesses the awesome power of the word ‘clean!’". In this maelstrom of marketing, who can say which clean energy technology is best?
