Lesson 1.  Energy Sources
 
 
There are many types of energy sources that humans depend on. One is the wind turbine. How does the wind turbine actually work to create electricity?
a)It relies on lightening during a severe thunderstorm to spark the electricity.
b)It relies on rainfall and then sunshine to create the electrical current.
c)It relies on devices that convert kinetic energy from the wind to mechanical energy.
d)It relies on kinetic devices to take an electric current from an existing source.


Answer: c
What specific role does photovoltaics (PV) play in that of solar energy?
a)It allows for the solar source to be photographed during the time it is being checked.
b)It allows light to be converted into electric current using a specific effect.
c)It allows for solar sources to be measured in nanometers for accuracy.
d)It allows for the energy to be captured immediately after it has been created.


Answer: b
What does the Department of Energy (DOE) say about the newly developed "clean coal technology”?
a)The DOE says that clean coal is better for houses than that of the type of coal used prior to today.
b)The DOE says that this technology is not recommended for houses and should only be used in business buildings.
c)The DOE says that this sharply reduces air emissions and other pollutants from coal burning power plants.
d)The DOE says that all coal is the same and that it is never been called a clean alternative to the dirty coal.


Answer: c
What is the primary reason that nuclear power plants are used to generate heat and electricity?
a)It emits a low amount of carbon dioxide and is able to generate a high amount of electrical energy in a single plant.
b)It emits a large amount of carbon dioxide and oxygen and generates a moderate amount of electrical energy in a single plant.
c)It emits large doses of smoke in the atmosphere but does not contribute highly to air pollution.
d)It emits small amounts oxygen into the atmosphere and is not costly to operate the large facility.


Answer: a
What is unique about using the solar method that is called the passive solar technique?
a)It uses the sun’s energy but only in small amounts as needed in different situations.
b)It includes positioning a building toward the sun and designing spaces that circulate air.
c)It includes giving a building a solar lighting system so that it may never be dark inside.
d)It includes spacing out the solar panels so the sun may only hit the surface of the panels.
