HOME ENERGY AUDIT: ELECTRICAL PRODUCTION WORKSHEET

Directions: Answer the questions below in the space provided.

1.What is the difference between between renewable energy and nonrenewable energy?

 

 

 

2. Identify the type of energy or resource in the follow statements.

 _____________________  a. This type of energy is from ancient swamps and is mined to produce the largest amount of electricity.
 _____________________  b. This type of resource uses materials that were living (organic material) and changes it by fermentation, conversion of gas and bacterial decay.
 _____________________  c. This type of energy uses photovoltaic cells to produce electricity.
 _____________________  d. This type of energy uses the heated water from the earth's core.
 _____________________  e. This type of energy uses the air in motion from the uneven heating of the earth to heat or produce electricity.
 _____________________  f. This type of energy uses the kinetic energy of the water.
 _____________________  g. This type of energy is a fossil fuel and is refined from crude oil making types of fuel and thousands of products.
 _____________________  h. This type of energy is found by itself, or in petroleum or coal beds.
 _____________________  i. This type of energy involves the nucleus of a atom.

3. We think that global warming is a fact, and that carbon dioxide is a major contributor to global warming. For every kilowatt-hour (kWh) of electricity 1.6 pounds of carbon dioxide is produced. If you use less energy, you reduce the amount of carbon dioxide that goes into the atmosphere.

Here are figures for some appliances. Estimate the number of hours each appliance uses to determine the amount of carbon dioxide produced.

  Example Using the Copier: 1265W/1000W/kW x 1.6 lb/kWh x 3 h/day x 365 day/yr = 2216.28 lb/yr
