Is There Enough Energy in the World for Everyone to Live Like Americans?

Many in the U.S. are trying very hard to 'go green', and they are using less gasoline, changing their light bulbs to CFL's, and recycling. Even with all of these efforts, if we multiply the amount of energy used per person in the U.S. by the world's total population…we'd have a problem…not enough energy to go around. We live well in the U.S., so it's understandable that people in other countries would want to live as well, but is there enough energy in the world for everyone to live like Americans? Do we have a shortage of energy, or an energy management problem? My guest, Susan Meredith, author of "Beyond Light Bulbs: Lighting the Way to Smarter Energy Management" will help us uncover the truth.
