Prospects For Solar Power Generation

The Genesis Plan proposed by Japan. Prepare to utilize the desert and ocean areas on the ground for power generation, and connect global solar power stations into a unified grid through superconducting cables to provide global power. According to calculations, by 2000, 2050, and 2100, even if all solar power is used to supply global energy, the land area will only be 651100 square kilometers, 1867900 square kilometers, and 8.2919 million square kilometers. 8.2919 million square kilometers account for only 2.3% of the total ocean area or 51.4% of the total desert area, and even 91.5% of the Sahara Desert. Therefore, this plan is possible to achieve.
Sky power generation plan. As early as 1980, NASA and the Department of Energy proposed the idea of building a solar power station in space, preparing to place a large flat plate 10 kilometers long and 5 kilometers wide in synchronous orbit, covered with solar cells, which could provide 5 million kilowatts of electricity. But this needs to address the issue of wireless transmission to the ground. Various schemes have been proposed, such as using microwave beams and laser beams. Although model aircraft have been used to achieve short distance, short time, and low-power microwave wireless transmission, there is still a long way to go before it is truly practical.
From the energy-saving and emission reduction goals of various countries and the United Nations' Special Report on Renewable Energy, it can be seen that achieving a high proportion of renewable energy substitution by 2050 is a global trend, which will promote the development of China's solar photovoltaic power generation industry. On October 26, 2012, State Grid Corporation of China issued the "Opinions on Doing a Good Job in Distributed Photovoltaic Power Generation Grid Connection Services", significantly reducing the threshold for photovoltaic power generation to enter the grid; The National Energy Administration has clearly stated that the installed capacity target is 100 million kilowatts by 2020, and for the next few years, it will exceed 10 GW of domestic installed capacity. By 2030, the total energy demand will reach 5 billion tons of standard coal, and by 2050 it will reach 5.2 billion tons. Renewable energy will account for 40% of the total energy demand in 2050, and renewable energy will account for 60% of the electricity demand. Photovoltaic power generation may require an installed capacity of 1 billion kilowatts. The strong support of national policies will promote the rapid and healthy development of China's solar photovoltaic power generation industry.
On December 24th, the National Energy Administration issued a notice on the preparation of the 13th Five Year Plan for solar energy development from the Comprehensive Department of the National Energy Administration. Among them, solar thermal power generation was mentioned as an important content, which means that solar thermal power generation will become an important industry that China will focus on developing during the 13th Five Year Plan period. The main types of solar energy utilization, with a focus on solar photovoltaic power generation and solar thermal utilization, should also include the content of solar thermal power generation in areas with conditions for solar thermal power generation engineering construction. The planning period is from 2016 to 2020, and the development goal is expected to reach 2030. The planning and research content of solar thermal power generation includes: key areas and scales of solar thermal power generation, site selection and construction conditions of key projects, technical routes, and technical and economic research. The research content of solar thermal utilization planning includes: solar thermal utilization goals, key areas, development models, urban and rural building application promotion methods and measures, etc.
