So we are in urgent need of energy conservation and environmental protection of new energy, reduce the production of carbon dioxide, the solar garden light is green lighting equipment, it is the solar energy as an energy source, is a renewable energy, does not emit carbon dioxide. Solar garden lamp USES the clean renewable energy, to replace the traditional high pressure sodium lamp lights can reduce carbon emissions. If the country city will be 20 million streetlights all use for solar garden light, can reduce 25. 8 million tons of carbon dioxide emissions, and is the equivalent of $10. 3 billion cost of carbon dioxide emissions.
