FREE CEM Test Energy Accounting and Economics Questions and Answers

Question 1

An industrial facility is billed for both energy consumption (kWh) and peak demand (kW).
Which of the following strategies would be most effective in specifically reducing the demand charge component of the utility bill?

Accepted Answer

Shifting the operation of a large, non-critical process from mid-afternoon to late at night.

Answer

Replacing all standard motors with high-efficiency motors.

Answer

Installing a more efficient HVAC system with a higher SEER rating.

Answer

Upgrading the facility's lighting to LEDs.

Question 2

A company is evaluating an energy efficiency project with a high initial cost but significant annual savings. Which financial metric is defined as the discount rate at which the net present value (NPV) of all cash flows (both positive and negative) from the project equals zero?

Accepted Answer

Internal Rate of Return (IRR)

Answer

Simple Payback Period (SPP)

Answer

Return on Investment (ROI)

Answer

Life-Cycle Cost (LCC)

Question 3

When performing a Life-Cycle Cost Analysis (LCCA) for a new chiller system, which of the following costs would NOT be included?

Accepted Answer

The cost of a previously conducted energy audit that identified the need for a new chiller.

Answer

Initial purchase and installation cost.

Answer

Annual electricity and water consumption costs.

Answer

Disposal and decommissioning costs at the end of the chiller's useful life.

Question 4

An energy manager is comparing two lighting retrofit projects. Project A has a Simple Payback Period of 2.5 years. Project B has a Simple Payback Period of 3.0 years. Why might Project B still be the better long-term financial choice?

Accepted Answer

Because Project B's equipment has a much longer useful life and lower annual maintenance costs.

Answer

Because a longer payback period always indicates higher quality equipment.

Answer

Because Simple Payback Period is the most comprehensive financial metric.

Answer

Because Project A must have a lower initial investment.

Question 5

The concept of the 'time value of money' is fundamental to energy economics. It is based on which of the following core principles?

Accepted Answer

A dollar received today is worth more than a dollar received in the future.

Answer

The cost of energy will always increase over time due to inflation.

Answer

All energy conservation measures have a positive return on investment.

Answer

Depreciation of equipment must be calculated on a straight-line basis.

Question 6

A project's Net Present Value (NPV) is calculated to be greater than zero. What does this indicate about the investment?

Accepted Answer

The project is expected to be profitable and exceed the minimum required rate of return.

Answer

The project's rate of return is exactly equal to the discount rate.

Answer

The investment will not be profitable and should be rejected.

Answer

The present value of the expected cash savings is less than the initial investment.
