In electricity energy structure of the United States now , each producing 60 billion kWh of electricity will produce about 1 million tons of carbon dioxide equivalent emissions. Assuming the United States remained present power structure in 2025 , the use of LED lighting especially the power LED light such as high power LED flood light will reduce annual emissions of 87 million tons of carbon dioxide equivalent . ” Kyoto Protocol” provides carbon dioxide emissions of greenhouse gases in most developed countries , If down by 7% compared with 1990 levels, or by 40 % compared with 2025 expected，the LED lighting including the high power LED flood light and other commercial or industrial and household LED lights can reduce primary energy consumption and a corresponding reduction in greenhouse gas emissions by 3% , then the LED lighting will make that the U.S. advance towards the goal of the Kyoto Protocol by 7.5 %. Even without considering the Kyoto Protocol , the global carbon emissions trading market, according to the current selling price is from $ 5 to $ 25 for per tonne of carbon dioxide emissions , reducing 87 million tons of carbon dioxide emissions mean the savings of approximately 400,000,000 to 20 billion dollars annually.

China is the world’s second largest country generating greenhouse gas only to the U.S. , mainly due to that the proportion of coal in China’s energy structure is more than 70% , the use of LED lighting particularly the high power LED flood light and other commercial and industrial or household LED light to reduce the effect of carbon dioxide emissions will be more obvious. As far as the environmental protection is concerned, the emissions of 750 million tons of coal annually is 20 million tons of SO2 in thermal power plant , converted H2SO4 3120 tons, these staggering numbers is sufficient to explain the importance of the development of high power LED flood light and other commercial or industrial and household semiconductor LED lighting.Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about the high power LED flood light.
