Study Notes

Energy Resources

  • Energy is crucial for various uses, including powering homes and industries.
  • Fossil fuels, such as coal, are non-renewable resources formed from ancient plant and animal remains over millions of years.
  • Fossil fuels are primarily hydrocarbons (compounds of carbon and hydrogen).
  • Coal is a solid form of fossil fuel created from compressed plant and animal matter.
  • Coal is composed of carbon and other elements like oxygen, hydrogen, nitrogen, and sulfur.
  • The process of coal formation is called coalification, a long process in which plant matter is buried and compressed in swampy environments.
  • Coal can be extracted using surface or underground mining techniques.
  • Coal's properties vary based on the level of compression during coalification (e.g., peat, lignite, bituminous, anthracite).
  • Crude oil, also known as petroleum, is a liquid fossil fuel formed from ancient marine organisms.
  • Crude oil can be extracted via surface mining (e.g., tar sands) or subsurface drilling.
  • Crude oil is refined to create usable fuels like gasoline, kerosene, and propane.
  • Natural gas is a fossil fuel derived from compressed organic matter. It exists as a gas, and is primarily composed of methane.
  • Conventional natural gas is extracted from porous rock formations or mixed oil reservoirs and accessed through drilling.
  • Unconventional natural gas may necessitate fracking (a stimulation technique) for extraction.
  • Solar energy derives from converting the sun's radiation into electricity using photovoltaic panels.
  • Biomass energy is obtained from organic matter, such as woody plants, grasses, agricultural residues, and algae.
  • Wind energy converts kinetic energy from wind into electricity using wind turbines.
  • Geothermal energy is generated from heat produced within the Earth.

Types of Resources

  • Renewable resources can be replenished within a human timeframe.
  • Non-renewable resources take millions of years to form and cannot be replenished.

Hydroelectric Power

  • Hydroelectric power uses water's kinetic energy to create electricity.
  • It is highly reliable and cost-effective.
  • Various hydroelectric plant types exist:
    • Pumped Storage: Stores energy by pumping water uphill during surplus periods for use when demand is high.
    • Run-of-River: Utilizes river flow without creating reservoirs.
    • Impoundment: Stores water in a reservoir behind a dam.

Hydropower Plant Classification

  • Micro Power Plant: Generates 1–100 kilowatts of power.
  • Small Power Plant: Generates 101–10 megawatts of power.
  • Large Power Plant: Generates over 30 megawatts of power.

Advantages of Hydroelectric Power

  • Minimal pollution due to no fuel combustion.
  • Renewable water resource as the primary energy source.
  • Relatively low operational and maintenance costs.

Disadvantages of Hydroelectric Power

  • High initial investment costs.
  • Reliance on precipitation for water supply.
  • Potential displacement of wildlife and human settlements.
