Study Notes
Energy Overview
- Energy is the capacity to do work, existing in various forms including thermal, electrical, mechanical, chemical, radiant, and kinetic.
- Conversion of energy allows it to change from one form to another during work processes.
Renewable Energy
- Renewable energy sources are inexhaustible and naturally replenished, e.g., solar, wind, tidal, wave, hydroelectric power, and biomass.
- These sources can be renewed by natural processes within approximately 100 years.
Nonrenewable Energy
- Nonrenewable energy sources cannot be replenished quickly; they take millions of years to form.
- These resources are typically extracted in solid, liquid, or gas forms.
Fossil Fuels
- Fossil fuels, including coal, oil, and natural gas, are derived from ancient organisms' remains subjected to heat and pressure.
- They are a significant nonrenewable energy source due to their long formation time.
Coal
- Coal is the most abundant fossil fuel, made up of at least 50% plant remains.
- Classified by carbon concentration levels into Peat, Lignite, Bituminous, and Anthracite.
Oil
- Oil is a viscous black liquid formed from marine organisms' remains, classified as a hydrocarbon.
Natural Gas
- Natural gas is a gaseous hydrocarbon that also originates from marine organisms' remains.
Energy Reserves
- Reserves denote the quantity of fossil fuel extractable at a profit with current technology.
Resources
- Resources serve as supply sources that can be utilized when necessary, offering support or assistance.
Conservation
- Conservation involves the wise management of natural resources to preserve and save them for future use.
Nuclear Energy
- Nuclear energy is generated through atomic reactions and serves as an alternative energy source.
Nuclear Fusion
- Nuclear fusion combines low-mass materials to create a substance of greater mass.
Nuclear Fission
- Nuclear fission involves splitting the heavy elements' nucleus (typically Uranium-235) to release energy, producing radioactive waste.
Solar Energy
- Solar energy harnesses heat and electricity directly from sunlight.
Wind Energy
- Wind energy is harvested from wind motion and can be used for transportation, electricity generation, and pumping water.
Hydro Energy
- Hydro energy utilizes flowing water to generate electricity.
Geothermal Energy
- Geothermal energy is derived from hot magma or dry rocks within the Earth's crust.
Biomass Energy
- Biomass energy comes from burning organic materials like wood, alcohol, and waste products.
