Global energy consumption growth in 2019 was the slowest in more than a decade. However，the energy structure has been further optimized，coal consumption has experienced negative growth，and renewable energy has become the biggest winner. The global per capita energy consumption is only 75.7 Gigajoule. The development of the world energy industry has a long way to go. As the world’s top three energy consumers，in 2019，China’s energy consumption slowed down and energy efficiency improveed；America was energy independent，with renewable energy overtaking coal for the first time in more than 130 years. India’s consumption continued to grow faster than the global rate and was poised to overtake the United States as the world’s second largest energy consumer. The COVID-19 pandemic in 2020 has led to the biggest impact on global energy demand since World War II. Negative oil prices appear for the first time in the 160-year history of the world oil industry. And it brings a historic decline in energy investment in 2020，which will lay a hidden danger to the stability of the world energy market in the future.
