Study Notes
Chapter 12: Non-Renewable Energy Sources
- Global fossil fuel use: 81% of total energy, utilizing 570 exajoules annually.
- Renewable energy use: 14%.
- Leading energy consumers: China (highest annual), US (highest per capita).
- Commercial energy: purchased and sold, including fossil fuels, nuclear, and renewables.
- Subsistence energy: directly obtained from natural resources (firewood, foraging, etc.).
- US energy consumption patterns: Petroleum highest, followed by natural gas, then coal; with a trend towards less reliance on coal and oil for energy.
- Annual US energy consumption: 103 exajoules; similar fossil fuel dominance to global patterns.
- Transportation: consumes nearly 30% of US energy, primarily due to cars, trucks, etc.
- US fuel economy: declined from past levels, then later saw improvements to reduce consumption and emissions.
Electricity Generation and Efficiency
- Electricity generation: accounts for ~40% of US energy use.
- Energy carriers: move energy in usable forms (electricity).
- Thermal power plants: convert fuel potential energy into electricity using turbines and generators.
- Steam generation: water boils to create steam, driving turbines connected to generators.
- Coal-fired electricity: combustion transfers heat to water generating steam, driving turbines, generating electricity.
Cogeneration
- Cogeneration: generates electricity and useful heat from a single fuel source, maximizing efficiency.
- Combined cycle systems: utilize exhaust gases from gas turbines to generate additional steam and thus more electricity.
Fossil Fuels
-
Coal: solid fuel formed from ancient plant matter; major reserves in the US, Russia, China, and India.
- Advantages: energy-dense, plentiful, inexpensive, easy to extract by surface mining.
- Disadvantages: impurities, pollutant emissions (Hg, Pb, As), ash, CO2 release.
- Peat: precursor to coal; formed in bogs where decaying vegetation accumulates.
- Coal types: lignite < bituminous < anthracite (increasing energy density).
-
Petroleum: liquid mixture of hydrocarbons, water, and sulfur; cleaner than coal than coal and convenient for use and transport.
- Advantages: energy-dense, relatively clean burning.
- Disadvantages: CO2 release, potential leaks during extraction and transport, air and water pollution.
- ANWR: Arctic National Wildlife Refuge (ANWR); debate about oil extraction vs. environmental impact.
-
Natural gas: cleanest fossil fuel; mostly methane; used for electricity, industrial processes and in residences.
- Advantages: low emissions, fewer impurities.
- Disadvantages: still emits greenhouse gases (methane), potential groundwater contamination from extraction (fracking).
Other Fossil Fuels
- Oil sands and liquid coal: bitumen (degraded petroleum) and CTL (coal-to-liquids) technologies.
- Energy intensity: energy use per unit of GDP; decreasing energy use per capita is beneficial to the environment.
- Hubbert curve: graphical representation of a resource's production over time; used to predict oil production peaks.
- Peak oil: highest point of global oil production.
Nuclear Energy
- Nuclear fission: splitting atomic nuclei to release energy.
- Uranium-235: main fuel source for nuclear power plants.
-
Chain reaction: fission triggers a self-sustaining process.
- Advantages: no air pollution.
- Disadvantages: accidents (Chernobyl, Fukushima), waste disposal concerns, potential for misuse of material.
- Radioactive waste: high-level (spent fuel rods) and low-level (protective clothing, tools); safe disposal methods are crucial.
- Half-life: time required for half a substance to decay.
- Nuclear fusion: combining lighter nuclei to release energy (theoretical future energy source).
Chapter 13: Energy Conservation and Increasing Efficiency
- Energy conservation: reducing energy consumption.
- Energy efficiency: maximizing the output of useful energy.
- Tiered rate system: pricing electricity based on usage levels (higher rate for higher use) in order to encourage conservation.
- Peak demand: highest energy usage at a time.
- Sustainable design: improving building efficiency and use of renewable resources (Passive solar technology, thermal mass).
- Passive solar Design: utilizing natural sunlight for heating and cooling (overhangs, window placements, thermal mass).
Renewable Energy
- Renewable/Nondepletable Energy Sources: energy that can be regenerated (Potentially renewable) or is effectively limitless on Earth's time scale.
-
Biomass: energy from plant matter; modern carbon vs fossil carbon; sustainable use is essential
- Solid biomass (wood, charcoal, manure).
- Biofuels: liquid fuels from biomass (ethanol, biodiesel).
-
Hydroelectric power: electricity generated using moving water.
- Run-of-the-river: hydroelectricity using natural river flow without dam storage.
- Water impoundment (dams): storing water behind a dam to generate power; benefits and environmental impacts (ecosystem disruptions, flooding land).
- Tidal energy: energy from water movement caused by tides.
-
Solar power: harnessing sunlight energy.
- Active solar: photovoltaic panels, water heaters.
- Concentrating Solar Power (CSP): use of mirrors or lenses to concentrate sunlight for thermal energy production.
- Wind power: using wind turbines to generate electricity.
-
Geothermal energy: heat energy from within the Earth.
- Direct heat use.
- Electricity generation via steam turbines.
- Ground source heat pumps.
- Hydrogen fuel cells: converting hydrogen into electricity chemically.
- Smart Grid: a digital grid that optimizes energy distribution and consumption.
- Energy Future Consideration: balancing practicality requirements against environmental responsibility to achieve environmentally conscious energy strategies.
