Solar panels may be more dangerous carbon dioxide emitting energy sources
On Whats up with that it has been pointed out that a greenhouse gas emitted during the production of solar panels and HDTV's, nitrogen trifluoride (NF3) that is used for cleaning the electronics, is about 17,000 times more potent a greenhouse gas than carbon dioxide.The amount of the gas in the atmosphere, which could not be detected using previous techniques, had been estimated at less than 1,200 metric tons in 2006. The new research shows the actual amount was 4,200 metric tons. In 2008, about 5,400 metric tons of the gas are in the atmosphere, a quantity that is increasing at a rate of about 11 percent per year. According to NASA.
Production of photovoltaics (PV) jumped to 3,800 megawatts worldwide in 2007, up an estimated 50 percent over 2006. At the end of the year, according to preliminary data, cumulative global production stood at 12,400 megawatts, enough to power 2.4 million U.S. homes. Growing by an impressive average of 48 percent each year since 2002, PV production has been doubling every two years, making it the world’s fastest-growing energy source. According to the Earth policy organisation.
In response to the growing use of the gas and concerns that its emissions are not well known, scientists recently have recommended adding it to the list of greenhouse gases regulated by the Kyoto protocol.The top five PV-producing countries are Japan, China, Germany, Taiwan, and the United States.Recent growth in China is most astonishing: after almost tripling its PV production in 2006, it is believed to have more than doubled output in 2007. With more than 400 PV companies, China’s market share has exploded from 1 percent in 2003 to over 18 percent today. Having eclipsed Germany in 2007 to take the number two spot, China is now on track to become the number one PV producer in 2008. The United States, which gave the world the solar cell, has dropped from third to fifth place as a solar cell manufacturer since 2005, overtaken by China in 2006 and Taiwan in 2007.
October 12, 2007 In another development that aims to make alternative power generation more efficient and more affordable, Braggone has discovered a method of capturing more light in a solar cell. The result is a new product line that greatly increases the efficiency of solar cells and allows manufacturing facilities to cost-effectively increase their capacity.
The question is will solar panels be efficient and durable enough in the near future to justify their emissions during the manufacturing process? Or is there another process by which Nitrogen trifluoride can be removed from the manufacturing process without other ecological impacts?
