With the increasing severity of global climate change, its negative impacts have become increasingly prominent. Urban areas, as the main source of energy consumption and carbon emissions, are facing unprecedented pressure to reduce emissions. In this context, it is particularly important and urgent to explore the potential application of renewable energy in urban areas and its impact on carbon emissions. This article focuses on this research, comprehensively analyzing various factors such as energy consumption structure, renewable energy resource endowment, and existing technology application in urban areas, and comprehensively evaluating the development potential of renewable energy in urban areas. The research results show that renewable energy, with its clean and renewable characteristics, has demonstrated significant effects in reducing the carbon footprint of urban areas. The large-scale application of renewable energy, such as solar and wind energy, can effectively replace traditional fossil fuels, reduce the carbon emission intensity during urban energy consumption, and provide strong support for cities to achieve low-carbon development. However, the promotion and application of renewable energy in urban areas have not been smooth sailing and still face many challenges. For example, the high cost of technology, inadequate energy storage facilities, and difficulties in connecting to the power grid have all to some extent constrained the large-scale application of renewable energy. In the future, it is necessary for the government, enterprises, and all sectors of society to work together and take effective measures to solve the problem, in order to promote the widespread application of renewable energy in urban areas and help cities achieve sustainable development goals.
