Study Notes

Electricity Production

Microbial Fuel Cells (MFCs): Bacteria "breathe" causing a chemical reaction that produces a flow of electrons. This electron flow can be harnessed to generate electricity.
Betavoltaics: Nuclear waste can produce nuclear particles that can be captured to generate electricity. This process is slow but long-lasting; a single betavoltaic cell can last up to 30 years but produces a small amount of energy.
Printable Organic Solar Cells: Semiconductor inks can be printed on various surfaces to create very thin, flexible, and inexpensive solar cells. These perform better in low light compared to traditional solar cells.

Storing Energy Technologies

Powerwalls: Tesla developed Powerwalls to store energy for later use, providing monitoring and metering.
Ultracapacitors: Energy storage is faster than batteries using capacitors. They can quickly store and release energy, smoothing out power delivery during surges.
Gravity Storage: Elevating water in a reservoir stores energy as potential energy, which can be used to power devices when needed.
Storing Energy as Heat: Concentrating sunlight to heat and melt salt stores energy that can be released later to create electricity at night.
Solid State Batteries: Offer higher energy density and are safer alternatives to lithium-ion batteries. They use solid electrolytes rather than liquid ones, preventing overheating and fire hazards.

Energy and Sustainability

Sustainable Energy: Renewable energy sources that can be replenished indefinitely without harming the environment.
Environmental Sustainability: Practices that don't harm the environment.
Social Sustainability: Practices promoting healthy living and fair wages.
Economic Sustainability: Practices that are practical and financially beneficial.
