Study Notes
Electricity Production (Emerging Technologies)
- Microbial Fuel Cells (MFCs): Bacteria "breathing" a chemical reaction generates electrons, creating electricity.
- Betavoltaics: Nuclear waste particles capture electrons to generate electricity. Slow but long-lasting (up to 30 years), low energy output.
- Printable Organic Solar Cells: Semiconductor inks printed directly onto surfaces, even irregular ones. Paper-thin, better in low light than traditional cells.
- Vertical Wind Turbines: Roadside turbines capture wind from passing vehicles or natural wind to generate electricity.
- Floating Solar and Wind Power: Generates electricity on water, eliminating ground-based support structures. Allows for increased production by moving offshore.
Social and Health Considerations
- Renewable vs. Non-renewable Energy: Renewable sources (e.g., solar, wind) have less negative social and environmental impacts than non-renewable sources (e.g., fossil fuels, nuclear).
- Renewable Benefits: Renewable energy creates local employment opportunities, improves health, ensures energy security, gives consumer choice, enhances living standards, creates communities, and develops career paths.
- Energy for Public Services: Energy powers essential services like health, education, and household well-being. It boosts time efficiency, communication, and investments.
- Electromagnetic Fields (EMF): High-voltage power lines produce EMFs. Research indicates these can affect human cells and bodily processes.
Storing Energy Technologies
- Powerwalls: Tesla's energy storage system for later use. Monitors and meters power consumption.
- Ultracapacitors: Rapid energy storage and release in comparison to batteries. Smooths out power delivery during surges in demand.
- Gravity Storage: Pumps water to a reservoir to store energy (potential energy). Gravity releases the energy when needed.
- Storing Energy as Heat: Sunlight heats salt to store heat energy that can generate electricity at night.
- Solid State Batteries: Can store more energy than lithium ion batteries; these are a crucial advancement and future of vehicle technology. Solid-state batteries have vastly improved safety and energy density compared to traditional lithium-ion batteries since they do not use liquid electrolytes.
Energy and Sustainability
- Definition of Sustainable Energy: Energy that can be replenished indefinitely without harming the environment long term.
- Types of Sustainability:
- Environmental: The energy production causes no lasting damage to the environment.
- Social: The energy production allows healthy lives and decent wages.
- Economic: The energy production is worthwhile on a practical level (financially viable).
- Examples of Sustainable Practices: Using more efficient equipment and devices.
