1. Economic development: Oil is an important part of the global energy market and plays an important role in economic development. The exploitation, refining and sales of oil have generated a large number of employment opportunities, and the oil industry has an important impact on the country's economic growth, fiscal revenue and international trade.
2. Energy supply: Oil is one of the most important energy sources in the world and is widely used in power generation, industrial production, transportation and other fields. The high energy density and convenient storage and transportation of petroleum make it an indispensable energy source in modern society.
3. Geopolitics: Because of the importance of oil, its supply and price have a far-reaching impact on international politics. Uneven distribution of oil resources has made some countries become big oil exporters, thus playing an important role in international relations. Interruption of oil supply or price fluctuation may trigger geopolitical tensions.
4. Environmental impact: Although oil is very important for economic and social development, its exploitation, refining and use also bring environmental problems. The consumption of oil has made an important contribution to global warming and air pollution, so it is an important issue to find alternative energy sources and environmentally friendly ways to use oil.
To sum up, the value of oil is social and historic, which has an important impact on economy, energy supply, geopolitics and environment.
