Study Notes
Energy Resources Overview
- Energy resources are materials utilized as energy sources.
- Categories include nuclear energy, fossil fuels (oil, coal, natural gas), and renewable sources (wind, solar, geothermal, hydropower).
Fossil Fuels
- Fossil fuels are derived from the fossilized remains of ancient plants and animals.
- Formed millions of years ago, they are found beneath the earth's surface and largely consist of hydrocarbons, which are compounds of carbon and hydrogen.
Types of Fossil Fuels
-
Coal
- Non-renewable solid fossil fuel with high carbon content.
- Originates from accumulated plant and animal matter over millions of years.
- Extracted through surface mining (removing rock and soil layers) and underground mining (using machinery to access deeper deposits).
-
Oil (Petroleum)
- Non-renewable liquid fossil fuel mainly composed of hydrocarbons.
- Formed from ancient marine organisms like algae and bacteria.
- Extracted through drilling on land or at sea; also from tar sands via strip mining.
- Refined into fuels such as gasoline, propane, and kerosene, and used in plastics and paints.
-
Natural Gas
- Odorless, colorless gas primarily made of methane (CH4).
- Originates from remains of plants and marine organisms, similar to other fossil fuels.
- Divided into conventional (easily extracted from rock beds) and unconventional (difficult to extract, requiring techniques like fracking).
Formation of Fossil Fuels
- All fossil fuels originated from living organisms that lived millions of years ago.
- Coal forms from terrestrial vegetation, while oil is formed from marine sources.
- Over time, these organisms are buried deeper, subjected to heat and pressure, leading to fossil fuel formation.
Uses of Fossil Fuels
- Coal is primarily used in power plants for electricity generation.
- Oil is converted into gasoline and diesel to fuel vehicles.
- Natural gas serves as a source of energy for heating and electricity generation.
Environmental Concerns
- Fossil fuels are non-renewable, leading to concerns about sustainability and long-term availability.
- Extraction and burning of fossil fuels contribute to environmental degradation and climate change.
