Solar power generation should be an alternative to thermal power

Statistics show that in 2013, fog affected 25 provinces and over 100 large and medium-sized cities; the average number of foggy days across the country was 29.9, the highest figure on record in 52 years. At the beginning of 2014, moderate to severe air pollution occurred in the central and eastern regions of our country due to foggy weather, which had a serious impact on the public’s health. This issue not only became a focus of societal attention but also turned into a serious social problem. Managing fog has become a top priority in work. Following the release of the \"Action Plan for Air Pollution Prevention and Control\" by the State Council, relevant departments have successively introduced measures for air pollution control.   To promote the rapid and healthy development of distributed photovoltaic power plants in China, a member of the National Committee of the Chinese People’s Political Consultative Conference and chairman of the board of Hanergy Holding Group proposed in a proposal submitted to the National Committee that the central government should further improve the subsidy policy per unit of electricity generated, exempt photovoltaic power generation enterprises from taxes and various administrative fees, and that local governments should actively cooperate with the central government to increase these subsidies.   Compared to traditional thermal power generation, photovoltaic power generation is a green, clean, and pollution-free energy source. Based on the conversion factor between electricity and standard coal, generating one kilowatt-hour of electricity via photovoltaics is equivalent to using 400 grams less of standard coal, resulting in a reduction of 997 grams of carbon dioxide emissions and 272 grams of dust emissions. Distributed photovoltaic power generation will be the trend of the future, and the \"home power stations\" that stem from this technology are gaining momentum in China.   Overall, **improving the subsidy policy per kilowatt-hour, increasing the amount of subsidies, and ensuring that these subsidy measures are implemented are the key ways to promote the sustainable development of distributed photovoltaic power plants.** Driven by **subsidy policies, if every family and enterprise in China were to establish photovoltaic power plants, China would become a huge photovoltaic power generation facility. It would be able to rid itself of its dependence on fossil fuels and achieve sustainable development, thereby perfectly resolving both energy security issues and air pollution problems.**

Large-scale replacement is not possible at the moment; investing there is not worthwhile

It is true that distribution is the trend of the future. Even according to Moore’s Law, it’s impossible for results to appear this quickly. China’s resource profile of abundant coal, scarce oil, and limited gas, together with the characteristics of distributed energy sources and the various requirements of electricity demand, mean that fossil fuels will remain the dominant source of electricity for a long time to come. Moreover, distributed energy requires a series of reforms, such as those in the power grid. The road ahead is long and arduous.

Current households can install systems with a resolution of 2K to 5K; the payback period for the investment is 3 to 5 years, and these systems can serve as a substitute for fossil fuels
