n order to make more extensive use of renewable energy, scientists have created the concept of alternative energy. Narrowly defined, alternative energy refers to energy sources that can replace oil; more broadly, alternative energy refers to energy sources that can replace all types of fossil fuels (fossil fuels include oil, gas and coal). Most new energy sources are alternative energy sources, including solar, nuclear, wind, and marine energy. The future development of alternative energy is a crucial strategic priority. From a broader perspective, this is actually a competition in scientific research, like an invisible war. Since advanced countries like the United States, Germany, and Japan started research and development in this field earlier, they have already achieved results in research on alternative fuels and the promotion of new energy sources.
