The urge to buy the latest gadget and to reform environmental misbehavior may be the twin pillars of 21st century American youth culture, but can the two ever be reconciled? Apple, Dell, Intel, Nokia and others—companies with an array of "green" initiatives and (more) environmentally friendly products—sure hope so. But wind power kite scientist and serial inventor Saul Griffith is skeptical, according to his keynote address at the Greener Gadgets conference in New York City this past Friday.
Griffith, the intellectual force behind wattzon.com ( where you can calculate the energy use of your lifestyle), has another term for the gadget-obsessed, himself included: "planet f&*kers." A detailed analysis of the energy required to produce everything from his daily glass of wine to his iPhone revealed that Griffiths requires some 25,000 watts of energy every day, or nearly twice that of the average American (who is already consuming at least six times as much as the average person in China and more than 20 times as much as the average Indian citizen).

For the first time in 30 years, the U.S. Environmental Protection Agency has tightened limits on lead emissions, a move that will require states to crack down on polluters that spew more than 1,300 tons of the metal annually.
The new standards, announced by the agency yesterday, limit emissions to 0.15 micrograms of lead per cubic meter of air (ug/m3). The previous standard, set in 1978, was 1.5 ug/m3.
"America's air is cleaner than a generation ago," EPA Administrator Stephen Johnson said in a statement. "With these stronger standards, a new generation of Americans are being protected from harmful lead emissions."
Ingestion of lead can cause brain damage, especially in young children. While the 1980 phase-out of lead in gasoline has curbed lead emissions by nearly 97 percent, according to the EPA, there are still as many as 16,000 industrial facilities, including iron and steel foundries and smelters that melt used batteries, which continue to expel the metal, the National Resources Defense Council (NRDC) says. Lead is also in airplane fuel.
