Answer the questions below regarding the heating of a house in the Midwestern United States. Assume the following.
• The house has 2,000 square feet of living space.
• 80,000 BTU's of heat per square foot are required to heat the house for the winter.
• Natural gas is available at a cost of $5.00 per thousand cubic feet.
• One cubic foot of natural gas supplies 1,000 BTUs of heat energy.
• The furnace is 80% efficient.
a. Calculate the following, showing all the steps of your calculations, including units.
i. The number of cubic feet of natural gas required to heat the house for one winter.
ii. The cost of heating the house for one winter.
b. Identify and describe three actions the residents of the house could take to conserve heat energy and lower the cost of heating the house.
c. The residents decide to supplement the heating of the house with a coal burning stove.
i. Identify 2 pollutants that may result from the burning of coal.
ii. Discuss one method that can be implemented to reduce the impact of the use of coal for energy.

a. The calculation of the requirements is as follows:

i. The cubic feet of natural gas required to heat the house for one winter is 160,000 (160,000,000/1,000).

ii. The cost of heating the house for one winter is $800 (160,000,000/1,000,000 x $5).

b. To conserve heat energy, lowering the cost of heating the house, the residents could take the following actions:

  • Turn off lights, computers, televisions, video games, and other electrical equipment when not in use.
  • Buy equipment with less energy consumption (that is, energy-saving appliances).
  • Adopt renewable energy sources.

c. i. Two pollutants resulting from burning coal are Sulfur dioxide (SO2) and Nitrogen oxides (NOx).

ii. One method to reduce the impact of coal energy is carbon capture. Carbon capture separates the CO2 and recovers it for underground permanent storage or sequestration.

Data and Calculations:

Square feet of the house's living space = 2,000

Heat per square foot = 80,000 BTU

Total heat required = 160,000,000 BTU (2,000 x 80,000)

Cost of natural gas per thousand cubic feet = $5

Cubit foot of natural gas = 1,000 BTUs of heat energy

Total cost of heating = $800 (160,000,000/1,000,000 x $5)
