Study Notes
Introduction to Fossil Fuels
- Fossil fuels are natural resources derived from the remains of ancient organisms buried under layers of earth.
- The primary types include coal, petroleum (crude oil), and natural gas.
Coal
- Forms from the remains of ancient plants due to heat and pressure over millions of years.
- Types of coal:
- Peat: The initial stage of coal, low in carbon.
- Lignite: Also known as brown coal, with low carbon content.
- Bituminous: Black coal with a higher carbon content, widely used for electricity generation.
- Anthracite: The highest grade of coal, possessing the highest carbon content and energy density.
- Main uses encompass electricity generation, steel production, and as fuel for various industries.
- Burning coal results in pollutants such as sulfur dioxide and carbon dioxide, contributing to air pollution and climate change.
Petroleum
- Forms from the remains of microscopic sea creatures and plants that become buried under sedimentary layers over millions of years.
- Composed primarily of hydrocarbons, which can be refined into multiple products.
- Applications include fuels like gasoline, diesel, and jet fuel, along with plastics, synthetic fibers, and lubricants.
- Environmental impacts include risks of oil spills, air pollution, and greenhouse gas emissions resulting from extraction and combustion.
Natural Gas
- Often found alongside petroleum, consisting mainly of methane.
- Recognized as a cleaner alternative to coal and oil.
- Uses extend to heating, electricity generation, and as feedstock in various industrial applications.
Alternative Energy Sources
- Renewable energy sources such as solar, wind, hydro, and geothermal energy are being explored to reduce fossil fuel dependence.
- Benefits of renewable sources include lower greenhouse gas emissions and enhanced sustainability over the long term.
Conservation and Future Outlook
- Conservation of fossil fuel usage is vital for environmental protection and combating climate change.
- Ongoing research aims to develop cleaner energy technologies and find more efficient methods to utilize fossil fuels.
