CEP Sustainability & Energy Efficiency 2

Question 1

Which metric is most commonly used to measure the energy efficiency of a data center's infrastructure?

Accepted Answer

Power Usage Effectiveness (PUE)

Answer

PUE is the industry-standard ratio of total facility energy to IT equipment energy, with a perfect score of 1.0.

Question 2

A company sets a Science-Based Target (SBT) for emissions reductions. Which global temperature goal do SBTs typically align with?

Accepted Answer

1.5°C or well-below 2°C above pre-industrial levels

Answer

Science-Based Targets align with the Paris Agreement goals of limiting warming to 1.5°C or well-below 2°C above pre-industrial levels.

Question 3

What is a Renewable Energy Certificate (REC) in the context of US energy procurement?

Accepted Answer

A tradable certificate representing 1 MWh of electricity generated from renewable sources

Answer

A REC represents the environmental attributes of one megawatt-hour of electricity generated and delivered to the grid from a renewable source.

Question 4

Which demand-side management strategy involves shifting energy-intensive operations to periods of lower grid demand or lower electricity prices?

Accepted Answer

Load shifting

Answer

Load shifting moves energy consumption from peak periods to off-peak periods without reducing total consumption.

Question 5

An energy auditor classifies a facility as needing a Level II energy audit. What does this typically include beyond a Level I audit?

Accepted Answer

Energy use analysis with standard measures and savings potential calculations

Answer

A Level II audit adds detailed energy use analysis and identifies ECMs with estimated savings and costs beyond the walk-through of a Level I.
