CEM Energy Economics and Financial Analysis 3

Question 1

A Time-of-Use (TOU) electricity rate structure is beneficial for energy managers primarily because it:

Accepted Answer

Provides opportunities to shift loads to lower-cost off-peak periods

Answer

Eliminates all demand charges from the utility bill

Answer

Guarantees a fixed electricity rate regardless of consumption

Answer

Reduces the need for power factor correction

Question 2

In energy management, carbon credits (carbon offsets) are primarily used to:

Accepted Answer

Offset greenhouse gas emissions through verified emission reductions elsewhere

Answer

Directly reduce a facility's energy consumption

Answer

Increase the efficiency of combustion equipment

Answer

Reduce the peak demand charges on utility bills

Question 3

The ENERGY STAR Portfolio Manager tool is primarily used by energy managers for:

Accepted Answer

Tracking and benchmarking a building's energy performance against similar buildings

Answer

Designing energy-efficient HVAC systems

Answer

Generating utility bill payments automatically

Answer

Controlling building energy systems in real time

Question 4

The Levelized Cost of Energy (LCOE) is defined as:

Accepted Answer

The net present value of total lifecycle costs divided by total lifetime energy production

Answer

The current utility rate per kilowatt-hour

Answer

The annual energy cost escalation rate

Answer

The demand charge per kilowatt of peak demand

Question 5

Utility rebates for energy efficiency projects are typically classified as:

Accepted Answer

Non-recurring benefits that reduce the net capital cost of the project

Answer

Taxable income that increases project costs

Answer

Annual operating cost savings

Answer

Debt financing that must be repaid over time

Question 6

In energy project financial analysis, sensitivity analysis is used to:

Accepted Answer

Assess how changes in key variables such as energy price or project cost affect financial outcomes

Answer

Determine the exact payback period of a project

Answer

Calculate the precise internal rate of return

Answer

Measure actual energy savings after project implementation

Question 7

When comparing natural gas cost ($/MMBtu) to electricity cost ($/kWh) for energy analysis, the correct conversion factor is:

Accepted Answer

1 kWh = 3,412 Btu

Answer

1 kWh = 2,413 Btu

Answer

1 kWh = 1,000 Btu

Answer

1 kWh = 10,000 Btu
