Core Viewpoint - The articles highlight the advancements and significance of solar thermal power generation in China and Africa, particularly focusing on the 50 MW molten salt tower solar power plant in Hami, Xinjiang, and the 100 MW Redstone solar thermal power plant in South Africa, showcasing China's role in green energy cooperation and sustainable development [2][8]. Group 1: Hami Solar Power Plant - The Hami solar power plant utilizes tower-type concentrated solar power technology, featuring over 14,500 heliostats that track the sun to concentrate sunlight onto a central receiver [4][6]. - The plant has an annual electricity generation capacity of approximately 198 million kWh, sufficient to meet the annual electricity needs of 240,000 people, while saving 61,900 tons of standard coal and reducing CO2 emissions by 154,800 tons [6][7]. - Hami's geographical advantages include high solar radiation, with an annual sunshine duration of 3,380 hours, making it an ideal location for solar energy development [3][4]. Group 2: Redstone Solar Power Plant - The Redstone solar power plant, located in South Africa, is the first tower-type molten salt solar power plant in sub-Saharan Africa, featuring over 40,000 heliostats that heat molten salt to 565 degrees Celsius for energy storage and continuous power generation [8][10]. - Once fully operational, the plant is expected to contribute approximately 480 GWh of clean electricity annually to the South African grid, meeting the energy needs of over 200,000 households [10][12]. - The project has created around 1,800 jobs, with over 85% of the workforce being local South Africans, and has injected approximately 7.5 billion rand into the South African economy [12][10]. Group 3: China's Role in Global Green Energy - China's total installed capacity for wind and solar power reached 1,206 million kW by July 2024, more than double the capacity at the end of 2020, significantly contributing to global climate change efforts [7][19]. - The country has signed cooperation agreements with over 40 developing countries to address climate change, establishing a "Belt and Road" green development international alliance [20]. - China's investment in clean energy is projected to reach $625 billion in 2024, accounting for one-third of the global total, with a contribution rate of over 45% to the increase in global non-fossil energy consumption over the past decade [19][20].
