Wannabe Green? The compact fluorescent lightbulb (CFL) is one way to help save the world. If each household in the U.S. swapped out one 60 watt traditional lightblub it would save enough electricity to power all the homes in Delaware and Rhode Island. In terms of oil not burned, or greenhouse gases not exhausted into the atmosphere, one bulb is equivalent to taking 1.3 million cars off the roads. Houses in the U.S. have 50 to 100 sockets, imagine if they all had the mighty CFL in them. Canon Rebel XTi, 1/250 sec @ f/20, ISO 100 with two off-camera strobes, one with a green gel. Thanks to Fast Company for the facts and figures and to Strobist.com for the lighting concept.
