Study Notes
Fossil Fuels Definition
- Fossil fuels are ancient fuels formed from the remains of living organisms, typically mined from underground and hundreds of millions of years old.
- Examples include coal, oil, and natural gas.
Formation of Fossil Fuels
- Fossil fuels form when organic matter, often plants or algae, is buried in an environment without oxygen.
- The plants are pushed to depths of several miles within Earth's crust, where pressure and heat cause them to transform into hydrocarbons.
Characteristics of Fossil Fuels
- Fossil fuels offer cheap, highly-concentrated energy.
- They pollute the air and are destined to run out.
Types of Fossil Fuels
- There are three types of fossil fuels: liquid (oil), gas (natural gas), and solid (coal).
- Oil can be found all over the world and is often extracted from ancient sea beds.
- Natural gas can be found in various underground rock formations and is mostly used in power plants to produce electricity.
- Coal is a black, sedimentary rock formed from the remains of ancient river mouths and is often mined on every continent.
Advantages of Fossil Fuels
- High energy density: Fossil fuels release large amounts of energy when burned.
- Low cost: Fossil fuels have been historically inexpensive due to their ubiquity and easy extraction.
- Abundant: Fossil fuels are available in large deposits, some of which could last for hundreds of years.
- Dispatchable: Fossil fuels can be adjusted according to demand, unlike renewable energy.
Disadvantages of Fossil Fuels
- Air pollution: Fossil fuels produce air pollution when burned, including carbon dioxide, carbon monoxide, and others.
- Climate change: Fossil fuels produce carbon dioxide, a greenhouse gas, leading to an increase in global temperatures.
- Water pollution: Fossil fuels can lead to unintentional water pollution, including runoff from coal mines and leaks in oil pipelines.
- Acid rain: The burning of coal can lead to acid rain, damaging everything from trees to fish eggs.
- Transportation: Fossil fuels have transportation issues, including maritime oil spills and escaped methane from natural gas pipelines.
- Non-renewable: Fossil fuels are non-renewable, meaning they will not be renewed during human lifetimes and will eventually run out.
