  • CO2 emission from cement manufacture to build the impoundment
  • lowered siltation
  • methane released as organic matter decomposes once covered by water
  • loss of habitat

  • 6. 
    The most commonly used approach to solar energy collection is ________, in which buildings are designed and building materials chosen to maximize their direct absorption of sunlight in winter, even as they keep the interior cool in the heat of summer.

  • Active
  • Passive

  • 7. 
    Passive solar design includes all of the following except

  • large windows on the south side of the house
  • floor and walls that will store heat in the winter
  • overhang that blocks the sun in the summer, but allows it inside in the winter
  • trees that block the sun for the entire year

  • 8. 
    According to the second law of thermodynamics, whenever one form of energy is transformed into another,

  • all of the energy is put to work
  • all of the energy is converted into a less usable form, like heat
  • some of the energy is converted to a less usable form, like heat
  • 50% of the energy is put to work, the rest is lost as heat

  • 9. 
    How does biomass reduce our carbon footprint by producing less CO2 than fossil fuels?

  • Plants absorb the same amount of CO2 that is released when it is burned.
  • Plants remove CO2 from the atmosphere and put it permanently into the ground.
  • Biomass filters CO2 to make it more environmentally stable.
  • Biomass doesn't release any CO2 when burned.

  • 10. 
    Which is NOT an example of biomass?

  • wood
  • crop leftovers (the part of the plant that isn't consumed)
  • manure and/or trash
  • petroleum

  • 11. 
    Which of the following DOES NOT use a turbine?

  • Hydroelectric
  • Wind
  • Solar
  • Nuclear

    Most of the developing countries in the world depend on _______ for their main source of energy.

  • renewable sources
  • nuclear
  • biomass (including wood, manure, etc)
  • coal

  • 13. 
    Ultimately, all biofuels are ________, because they are the result of ________.

  • geological; sedimentation
  • solar; photosynthesis
  • inefficient; decomposition by microorganisms
  • synthetic; chemical manipulation of hydrocarbons

  • 14. 
    All of the following renewable resources are derived from the sun in some way EXCEPT

  • biomass
  • wind
  • hydroelectric

  • fossil fuels
  • biofuels
  • solar energy
  • geothermal energy

  • 16. 
    Put the items below in correct sequence for the generation of electricity using the wind 1 – generator converts mechanical energy into electrical energy 2 – wind turns the wind turbine blade 3 – the gear box transfers mechanical energy to the generator 4 – electricity is transferred to the grid
