Energy Net on 13 Dec 08Think switching to solar energy will make you green? Think again. Many of the newest solar panels are manufactured with a gas that is 17,000 times more potent than carbon dioxide in contributing to global warming. Nitrogen trifluoride, or NF3, is used for cleaning microcircuits during the manufacture of a host of modern electronics, including flat-screen TVs, iPhones, computer chips-and thin-film solar panels, the latest (and cheapest) generation of solar photovoltaics. (Time named the panels one of the best inventions of 2008.) Because industry estimates suggested that only about 2 percent of NF3 ever made it into the atmosphere, the chemical has been marketed as a cleaner alternative to other higher-emitting options. For the past decade, the U.S. Environmental Protection Agency has actively encouraged its use. NF3 also wasn't deemed dangerous enough to be covered by the Kyoto Protocol, making it an attractive substitute for companies and signatory countries eager to lower their emissions footprints.
