Oil is a vital energy resource that powers much of the modern world. It is extracted from the earth and refined into various products, including gasoline, diesel, and jet fuel, which are essential for transportation and industry. The production and consumption of oil have significant economic and environmental impacts. Countries rich in oil reserves, such as Saudi Arabia and Russia, play a crucial role in the global market. However, the reliance on oil also raises concerns about climate change and the need for sustainable energy alternatives.
