CEM Energy Economics and Financial Analysis

Question 1

A lighting retrofit costs $50,000 and saves $10,000 per year in energy costs. What is the simple payback period?

Accepted Answer

5 years

Answer

Simple payback period = Initial investment / Annual savings = $50,000 / $10,000 = 5 years.

Question 2

Which statement about Net Present Value (NPV) is correct when evaluating energy projects?

Accepted Answer

A positive NPV indicates the project generates more value than its cost of capital

Answer

A positive NPV means the present value of cash inflows exceeds the present value of costs, indicating the project creates value above the required return.

Question 3

In energy project financial analysis, the discount rate is used to:

Accepted Answer

Convert future cash flows to present value

Answer

The discount rate reflects the time value of money by converting future cash flows into their equivalent present-day value.

Question 4

Life Cycle Cost (LCC) analysis differs from simple payback analysis primarily because LCC:

Accepted Answer

Accounts for all costs over the entire life of the equipment

Answer

Life Cycle Cost analysis includes all costs over the equipment's lifetime: initial capital, operating, maintenance, energy, and disposal costs.

Question 5

The Internal Rate of Return (IRR) of an energy project is best defined as:

Accepted Answer

The discount rate at which the NPV equals zero

Answer

IRR is the discount rate that makes the NPV of all cash flows from a project equal to zero, representing the project's effective rate of return.
