Solar Energy and Environmental Sustainability: Cost Benefit Analysis and Ecological Impact Assessment

Energy is one of the most significant research topics in today’s world. Solar energy, as a sustainable renewable energy source, has always been at the forefront of development and application, but it’s still facing challenges. This paper researches the sustainability of solar energy technology through three assessment methods, including its lifecycle, the environmental and economic impact, and analyzes and proposes optimization suggestions for the special situation of the Chinese. Studies have indicated that solar energy technology has shown positive influences in both aspects of economy and ecology, and has immeasurable value in achieving global energy transformation and environmental protection. However, at the same time, in the future, promoting conversion efficiency and reducing the costs of installation and maintenance are the key breakthroughs needed for further development and application of solar energy technology. With these efforts, solar energy will play a more significant role in the global energy structure and make a greater contribution to achieving carbon neutrality goals.
