...corner of the country. Development on the bulb didn't stop either: researchers have modified Edison and Swan's design further, refining the filament by using tungsten and filling the vacuum with gas, both of which increase the life span of a bulb. Still, even modern bulbs are inefficient - less than 6% of the energy used by a bulb goes into producing light. The rest is given off as heat...
That fact explains the effort under way to drive consumers toward a better bulb: compact fluorescent lamps (CFLs), which last 10 times as longer as their incandescent counterparts while consuming less than one-third the electricity. The European Union began phasing out incandescents on Sept. 1, banning stores from buying new stock. At up to $10 each, CFLs are more expensive, but experts say they pay for themselves in energy savings within just a few months. The E.U. is even touting the switch as an economic stimulus; experts estimate that the swap to CFLs will save customers €5 billion...

Over the subsequent semesters, I’ve combined courses in social and political theory with the sporadic environmental offerings of other social science and humanities departments. In this way, I cobbled together a concentration that more or less worked for me. Now, looking back over my Harvard experience, I’m happy, but I fear I’m an exception. Without sufficient courses, or a clear track or concentration to follow, Harvard students with nonscientific environmental interests sometimes give up, study other issues, or (often unhappily) settle...

"I am a firm believer that with success comes responsibility and the incredible power of possibility - a responsibility to help those less fortunate and the possibility of actually succeeding in making a difference." Whether he can make that difference from a U.S. prison cell remains to be seen...
