Answer: Oil.
Some extra relevant information:
One of the most commonly used fossil fuels for heating and cooking purposes is natural gas.
Natural gas is a fossil fuel formed from the remains of marine organisms that lived millions of years ago. It is typically found deep beneath the Earth’s surface, often trapped in folded or tilted layers of rock.
The process of natural gas formation begins when plants and tiny marine organisms die and sink to the bottom of oceans or lakes. Over time, these organic materials become buried under layers of sediment. As more and more sediment accumulates, the pressure and heat from the Earth’s crust transform the organic matter into fossil fuels, including natural gas.
Unlike other fossil fuels such as coal and oil, natural gas primarily consists of methane, a powerful greenhouse gas. It is a highly flammable substance that is odorless and colorless in its purest form. However, to detect any potential leaks, a distinct odorant called mercaptan is added to natural gas before it is distributed to consumers.
Due to its abundance and relatively low carbon dioxide emissions compared to other fossil fuels, natural gas has become an increasingly popular choice for heating homes and commercial buildings, as well as for cooking. It is widely used in stoves, ovens, and water heaters, providing a reliable and efficient source of energy.
Nevertheless, the extraction, production, and transportation of natural gas can have environmental impacts. Drilling techniques, such as hydraulic fracturing or “fracking,” have raised concerns about groundwater contamination and methane leaks. As the world seeks to transition towards cleaner and more sustainable energy sources, the role of natural gas in the global energy mix remains a topic of debate and scrutiny.
