Energy is the ability to do work, and it comes in various forms, such as electricity, heat, and motion. One of the most significant sources of energy is oil, a fossil fuel formed from ancient plants and animals. Oil is extracted from the ground and refined into products like gasoline, diesel, and jet fuel, which power vehicles and machinery. The demand for oil has a major impact on the global economy and environment. As countries strive for energy security, they often rely on oil imports, leading to geopolitical tensions. Additionally, burning oil contributes to climate change, prompting a shift towards renewable energy sources like solar and wind.
