8.2.6

8.2.6 Discuss the relative advantages and disadvantages of various energy sources.
**
 * **Energy Source** || **Advantages** || **Disadvantages

|| (Uranium Fission) || # High energy density (Plutonium Fission) || # High energy density (Photovoltaic) || # Clean (solar heating panel) || # Clean 2. Yields less energy 3. Turbines are [|costly] 4. Takes space 5. Creates noise pollution || Tim Kirk [|Solar (Photovoltaic)][|Solar (solar heating panel)] [|Hydroelectric][|Fusion] [|Fission] [|Wave] || [|Wind] [|Hydro. 1] [|Hydro. 2] [|Hydro. 3] [|Fossil Fuels] [|Fusion 1] [|Fusion 2] [|Fission] [|Uranium 1] , [|Uranium 2] [pt 4 for all nuclear] Uranium [pt 5] [|Wave] Help from Mr. W Tim Kirk Good site for [|review] ||
 * FOSSIL FUELS || # High energy density
 * 1) Easy to transport
 * 2) Cost effective || # Global Warming
 * 3) [|Acid rains]
 * 4) Quantity is scarce
 * 5) Prices ||
 * NUCLEAR
 * 1) Large reserves compared to oil
 * 2) No greenhouse gas waste || # Quantity is scarce
 * 3) Workers in danger
 * 4) H 2 O becomes radioactive
 * 5) Need place for wastes
 * 6) Non-renewable
 * 7) Ore is also radioactive
 * 8) Need to be careful when transporting U to power plant ||
 * NUCLEAR
 * 1) No greenhouse gas waste
 * 2) Uses by-product of Uranium Fission as fuel || # Need place for wastes
 * 3) Could lead to uncontrolled reaction.
 * 4) Readily usable, so this could be used as a weapon ||
 * NUCLEAR (Fusion) || # Readily available
 * 1) Inexhaustible (Deuterium and Tritium)
 * 2) No toxic gas emissions
 * 3) No dangerous by-products || # Many countries gave up
 * 4) Reaction not long enough
 * 5) Need place for wastes
 * 6) Some optimal reactors require rare fuel, like He-3. ||
 * SOLAR
 * 1) Take advantage of unused space (e.g. rooftops)
 * 2) Renewable
 * 3) Low/no maintenance || # Only used during day
 * 4) Cloudy day
 * 5) Need space
 * 6) More costly (compared to solar heating panel)
 * 7) Efficiency: ≈ 40% ||
 * SOLAR
 * 1) Cost effective (in the long run)
 * 2) Renewable
 * 3) Low/no maintenance || # Used only during the day
 * 4) Weather dependent
 * 5) Need space
 * 6) Inefficiency from converting solar energy ||
 * HYDROELECTRIC || # Cost effective (free source)
 * 1) Minimal pollution
 * 2) Renewable
 * 3) Inexhaustible || # Affect mobility of fish
 * 4) Formation of [|Scour holes]
 * 5) Lose land and people need to move
 * 6) Can be disastrous
 * 7) Only used in those areas
 * 8) Supersaturation of air into water ||
 * WIND || # Clean
 * 1) Renewable
 * 2) Sustainable
 * 3) Economical
 * 4) Ample || 1. May be too weak
 * WAVE (OWC) || # Predictable
 * 1) Strong in winter
 * 2) Cost effective || # May be too weak
 * 3) Suitable site needed
 * 4) OWC must be strong enough ||
 * Fission in general || # Little fuel needed
 * 1) Does not contribute to global warming || # Dangers of uncontrolled reaction
 * 2) Waste can be produced for weapons
 * 3) Costly ||
