Analysis on energy saving benefit transformation of LED lighting

How about the cost performance of LED lighting implementation? What is the source of investment funds and benefits of the transformation? This is a question that the market is worried about whether LED can be promoted on a large scale. Take the LED street lamp with 100W photoelectric as an example. The cost of purchasing LED street lamps a year ago was 25003000 yuan. At present, the price of street lamps has dropped to 1500 yuan and 1800 yuan, the return period for replacing the 8001200-yuan high-pressure sodium lamp was reduced to 23 years. However, LED street lamps save energy by 50 and have a service life of 9 years, during which lamps do not need to be replaced. The cost performance of LED used in new street lamps is already very obvious. Regarding the funds for transforming and replacing LED street lamps, Guangdong proposed in the implementation plan for promoting the use of LED lighting products, local finance will solve the source of funds for LED lighting renovation projects from the additional income of urban public utilities collected with electricity charges. According to the data of LED demonstration projects in the past two years, Guangdong provincial science and technology department has calculated the economic benefits and energy saving and emission reduction effects of LED street lamp renovation projects. According to the calculation of 2 million LED street lamps, before the renovation, the annual electricity charge for street lamps reached 2 billion yuan, and the annual lamp replacement fee reached 0. 5 billion yuan, thus the total annual cost reached 2. 5 billion yuan. After the renovation, the total annual cost savings are 1. 5 billion yuan, including 50 yuan of electricity and 0. 5 billion yuan of lamp replacement fees. The total investment for the transformation of 2 million LED street lamps is 48. 0. 9 billion yuan, plus the total cost of the loan interest rate, totaling 6. 1 billion yuan. During the 9-year life of LED street lamps, a total of 13. 5 billion yuan will be saved, and the local finance will receive an energy-saving income of 7. 4 billion yuan. In addition, it will save 10. 8 billion kWh of electricity, equivalent to saving 3. 79 million tons of standard coal, 70 thousand tons of sulfur dioxide emissions, 2. 68 million tons of carbon dioxide emissions and 70 thousand tons of soot emissions. It can be seen that extracting energy-saving benefits proportionally from the additional income of urban public utilities levied with electricity charges can fully pay for the investment in LED transformation, and can produce obvious economic benefits and energy-saving and emission-reduction effects.
