APES Unit 10

• What emissions does hydrogen fuel release?


  None; it minimizes air pollution.
• Drawbacks of Geothermal Energy

  Reservoirs can be depleted; minerals can corrode equipment.
• How does a PV Cell work?

  Photovoltaic Cells (aka PV Cells) convert solar energy to electrical energy.
• Advantages of Passive Solar Energy

  Absorbs and stores heat from the sun directly within an insulated structure without pumps or fans.
• What types of energy come directly and indirectly from the sun?

  Direct: Solar

  Indirect: Wind, Biomass, Fossil Fuels, and Hydroelectric
• Drawbacks of Wind Power

  Some sites have intermittent wind (wind isn't there always), NIMBY (Not In My Back Yard), windmills can kill birds / bats.
• How do solar thermal power plants work?

  They concentrate and transform energy from the sun into heat.
• What is a fuel cell vehicle?


  Fuel cell cars would work by using hydrogen to power the motor and start. Hydrogen fuel cell cars can only emit vapor and heat instead of carbon monoxide and nitrogen oxides.
