fossil fuel

Thân thiện

Coal, oil, and natural gas are common types of fossil fuel.

Definition

Noun: A fossil fuel is a fuel that is formed naturally in the Earth's crust from the decomposed remains of ancient organisms (such as plants and animals) over millions of years. These fuels have a high carbon and hydrogen content and are extracted and burned to produce energy.

Usage

Fossil fuels are used as a primary source of energy for electricity generation, transportation, and heating. The term is typically used in singular or plural form to refer to the category of non-renewable energy sources. * Coal, oil, and natural gas are the three main types of fossil fuel. * The burning of fossil fuels releases carbon dioxide into the atmosphere. * Many countries are trying to reduce their dependence on fossil fuels.

Examples

• The power plant generates electricity by burning fossil fuel.
• Scientists warn that continued use of fossil fuels contributes significantly to climate change.
• A major challenge for the 21st century is finding alternatives to fossil fuels.

Advanced Usage
