Study Notes
Hydroelectric Power Energy Source
- Energy originates from moving water (rivers or tides)
High-Energy Element
- Uranium-235 has significantly greater energy content than coal.
Fossil Fuel Electrical Production in the US
- Approximately 85% of US electricity comes from fossil fuels.
Fossil Fuel and Biomass Combustion Byproducts
- Burning fossil fuels and biomass produces carbon dioxide and water vapor.
Hydroelectric Dam Environmental Disadvantage
- Disruption of local ecosystems is a significant environmental concern with hydroelectric dams.
Nuclear Reactor Fuel
- Uranium is the primary fuel in nuclear reactors.
Petroleum Processing
- Refining petroleum is a process to obtain fuels like diesel and octane.
Nuclear Reaction Result
- Matter is converted into energy in both nuclear fusion and fission.
Wind Energy Advantages
- Advantages of wind energy include its clean nature and abundance.
Wind Energy Disadvantages
- Disadvantages of wind energy include intermittency (depending on wind) and potential visual impact.
Tidal Energy Description
- Tidal energy captures the energy of rising and falling tides, using the flowing water's movement.
- It is considered a renewable energy source.
Generator Function
- A generator converts mechanical energy into electrical energy.
Nuclear Fission vs. Fusion
- Fission: Heavy nuclei split, releasing energy.
- Fusion: Light nuclei combine, releasing energy.
Fossil Fuel Renewable Status
- Fossil fuels are non-renewable resources.
Hydrogen Fuel Cell Byproduct
- Hydrogen fuel cells primarily produce water as a byproduct.
Geothermal Energy Source
- Geothermal energy originates from Earth's internal heat.
