Study Notes
Coal Types and Characteristics
- Anthracite is the highest rank of coal, characterized by a high percentage of fixed carbon.
- Bituminous coal is distinguished by its higher carbon content compared to sub-bituminous and lignite coals, making it more efficient for energy production.
- Lignite coal has the least concentration of carbon among coal types.
Coal Usage and Environmental Concerns
- Bituminous coal is the most common type used in electricity generation in the United States.
- The primary environmental concern associated with coal is its contribution to air pollution and greenhouse gas emissions.
Non-Renewable Energy Characteristics
- A main limitation of non-renewable energy sources like coal is their finite availability and the environmental degradation they cause during extraction and use.
- Coal is considered a non-renewable energy source because it takes millions of years to form and is being consumed at a faster rate than it can be replenished.
Geological Composition and Formation
- Coal is primarily composed of carbon-rich organic material that derives from ancient plant life.
- The plants that formed coal lived during the Carboniferous geological period, which occurred approximately 359 to 299 million years ago.
Coal Energy Generation Process
- In coal energy generation, water is converted into steam through a process of heating in a boiler, driven by burning coal.
- Coal is categorized as a fossil fuel because it originates from decayed plant material that has been subjected to heat and pressure over geological time periods.
Oil and Gas Characteristics
- The main product derived from oil is gasoline, used primarily as fuel in vehicles.
- Crude oil cannot be used immediately as an energy source after extraction due to the need for refining to separate it into various fuels and byproducts.
- Natural gas primarily consists of methane, which is crucial for combustion processes.
Fuel Processing and Use
- The refining process involves cleaning and separating crude oil into fuels like gasoline, diesel, and other byproducts.
- Propane is considered a hydrocarbon fuel and is commonly used in heating and cooking applications.
- Natural gas is mainly utilized in heating applications due to its efficiency and cleaner-burning properties compared to other fossil fuels.
