Biology 104- Exam 5 with correct
Answers
Wind Turbines - Answer -are machines that use flowing air over oceans and land
masses to turn large blades that in turn power a generator and create electricity
Variable generation - Answer -a power source with generating capacity that changes
according to the time of day, weather conditions, and other factors
Photovoltaic Solar Panel - Answer -is made of silicon and produces an electric charge
when exposed to sunlight
Concentrated Solar Thermal Plant - Answer -another technology that captures heat
from the sun by using mirrors to focus sunlight toward liquid-filled pipes or a centrally
located "power tower"
Hydropower - Answer -generated when water is used to spin turbines and generate
electricity
Nuclear Power - Answer -where the nuclei of unstable Uranium atoms are split,
releasing large amounts of heat energy
Fission - Answer -The splitting of an atomic nucleus to release energy and more
neutrons that can in turn split the nuclei of additional atoms in a chain reaction
Geothermal Power - Answer -generated by heat from below the Earth's surface
Ethanol - Answer -an alcohol produced by fermenting sugars in plants such as corn or
sugarcane and then blended with gasoline
Electric Vehicle - Answer -is powered by an electric motor using a generate motion
Fuel cell - Answer -a device that creates an electric current by stripping electrons from
hydrogen molecules
Cogeneration - Answer -captures waste heat from power plants and uses it as an
additional source of heating and cooling
