Recently, Beijing haze is again the top news. “The thick and the fog”, “buried head and work hard”, “serve for the people”, “self-improvement does not suck”, “ten face crouching”, smog has become the most ranting events at the moment. There, the world is promoting green power.
In fact, not only in China, Italy, Spain in Europe, India in Asia, Korea and many countries around the world have experiences different degrees of smog weather and have launched different levels of air pollution warning mechanism.
Whether it is to complete a major proposition of global climate governance or to solve some of the smog problems in China, it is calling for more innovative technologies to lead the arrival of the world energy revolution. In addition to meteorological conditions, industrial production, motor and vehicle emission, winter coal heating and other reasons that increase the atmospheric particulate matter concentration is an important factor that cause the haze.
The main source of PM2.5 is anthropogenic emissions. Humans emit not only PM2.5 directly but also some gas pollutant, which are transformed into PM2.5 in the air. Direct emission mainly comes from combustion processes, such as burning fossil fuels (coal, gasoline, diesel), burning biomass (straws, firewood) and waste incineration. The gas pollutants that transformed into PM2.5 in the air include sulfur dioxide, nitrogen oxides, ammonia and volatile organic compounds. Other sources of manmade pollutant include: road dust, construction dust and industrial dust.
The haze weather is not only harmful to traffic but also greatly harm to the human body. It will induce respiratory diseases, heart diseases and increase in infectious diseases, which is fatal if serious. More alternative clean energy is required to reduce the carbon emissions. Green power is non-polluted, inexhaustible and is capable of exploit and utilize anywhere without the need to mining and transportation.
As promoting green power can alleviate pollution and cope with the energy crisis, green power is the most attractive, most developed and the most widely used clean energy among all the renewable energy.
Saving the “Smog Day”, there is a long way to go. Photovoltaics people are trying hard, DEL people are making great efforts. DEL smart solar street light call on photovoltaics enterprises striving to innovative scientific research and promote green power industry with new technologies. Let us say goodbye to “haze” soon, and return me a fresh blue sky.
