석유(petroleum)란?

석유(petroleum)는 고대 생물의 잔해가 수백만 년 동안 지구의 압력과 온도에 영향을 받아 형성된 자연 발생하는 유기 화합물로 구성된 액체입니다. 석유는 주로 지구의 지각 속 암석 층에서 발견되며, 이를 통해 원유(raw crude oil)를 추출하여 여러 가지 석유제품으로 정제됩니다.

석유는 현대 산업과 교통수단의 주요 에너지원으로 사용되며, 연료, 윤활유, 고무, 플라스틱, 화학 제품 등 다양한 제품을 생산하는 데 필수적인 원료입니다. 석유는 가솔린, 디젤, 석유 가스, 제트 연료 등 여러 가지 형태의 연료로 정제되어 사용됩니다.

그러나 석유 사용은 환경 문제를 야기하기도 합니다. 석유를 연료로 사용하면 대기 중 이산화탄소와 기타 온실가스가 발생하여 기후변화에 영향을 줄 수 있습니다. 또한 석유의 공급과 수요에 따른 가격 변동성과 지정학적 긴장감도 석유에 대한 의존성을 줄이고 대체 에너지원을 찾아야 하는 이유 중 하나입니다. 이에 따라 태양광, 풍력, 지열, 수력 등의 재생 가능 에너지원이 점점 더 중요해지고 있습니다.

 

Petroleum is a liquid composed of naturally occurring organic compounds formed by the remains of ancient organisms under the pressure and temperature of the Earth over millions of years. Petroleum is found primarily in rock layers within the Earth's crust, from which raw crude oil is extracted and refined into a variety of petroleum products.

Petroleum is used as the primary source of energy for modern industry and transportation, and is an essential raw material for producing a wide variety of products, including fuels, lubricants, rubber, plastics, and chemicals. Petroleum is refined and used in several forms of fuel, including gasoline, diesel, petroleum gas, and jet fuel.

However, the use of petroleum also creates environmental problems. The use of oil as a fuel produces carbon dioxide and other greenhouse gases in the atmosphere, which can contribute to climate change. In addition, price volatility and geopolitical tensions due to the supply and demand for oil are also reasons to reduce our dependence on oil and find alternative energy sources. In response, renewable energy sources such as solar, wind, geothermal, and hydroelectricity are becoming increasingly important.
