ENG-3.C—Identify types of fuels and their uses

Identify types of fuels and their uses.

• Wood is commonly used as fuel in the forms of firewood and charcoal. It is often used in developing countries because it is easily accessible.
• Peat is partially decomposed organic material that can be burned for fuel.
• Three types of coal used for fuel are lignite, bituminous, and anthracite. Heat, pressure, and depth of burial contribute to the development of various coal types and their qualities.
• Natural gas, the cleanest of the fossil fuels, is mostly methane.
• Crude oil can be recovered from tar sands, which are a combination of clay, sand, water, and bitumen.
• Fossil fuels can be made into specific fuel types for specialized uses (e.g., in motor vehicles).
• Cogeneration occurs when a fuel source is used to generate both useful heat and electricity.
• Enduring understanding ENG-3: Humans use energy from a variety of sources, resulting in positive and negative consequences.
