The analysis report shows that the increasing energy consumption, especially the significant use of fossil fuels such as coal and oil, poses a serious threat to the environment and global climate, posing a serious threat to the goal of sustainable human development. According to predictions, based on existing technologies for extracting non renewable energy and the continuous consumption rate of these fossil fuels day and night, the useful lives of coal, natural gas, and oil are estimated to be 100-120 years, 30-50 years, and 18-30 years, respectively. Obviously, the biggest challenge and dilemma facing the 21st century may not be war and food, but energy.
On January 19, 2016, the World Energy Agency stated that due to new solar cell technology and other technological advancements driving down prices, the cost of battery energy storage will decrease by 70% over the next 15 years.
