Abstract
Energy has always been the cornerstone of the development of the world and even human society. Energy affects mankind in economy, life, culture and other aspects. Therefore, energy has always been one of the most important things in human society. As the world changes, energy security is always on the minds of world leaders. At the same time, as a very important investment product in the world, the price trend of energy has been affecting the attention of investors around the world. Therefore, this paper will take the European natural gas price as an analysis case, and help analyze the possible trend of the European natural gas price by analyzing the demand and supply and detailing the supply situation. In addition, this paper will analyze European energy supply sources in detail, and put forward constructive suggestions for European leaders to solve energy security problems with the goal of helping Europe achieve energy self-sufficiency.
