Which metric is most commonly used to measure the energy efficiency of a data center's infrastructure?
Answer: Power Usage Effectiveness (PUE)
PUE is the industry-standard ratio of total facility energy to IT equipment energy, with a perfect score of 1.0.
A company sets a Science-Based Target (SBT) for emissions reductions. Which global temperature goal do SBTs typically align with?
Answer: 1.5°C or well-below 2°C above pre-industrial levels
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.
What is a Renewable Energy Certificate (REC) in the context of US energy procurement?
Answer: A tradable certificate representing 1 MWh of electricity generated from renewable sources
A REC represents the environmental attributes of one megawatt-hour of electricity generated and delivered to the grid from a renewable source.
Which demand-side management strategy involves shifting energy-intensive operations to periods of lower grid demand or lower electricity prices?
Answer: Load shifting
Load shifting moves energy consumption from peak periods to off-peak periods without reducing total consumption.
An energy auditor classifies a facility as needing a Level II energy audit. What does this typically include beyond a Level I audit?
Answer: Energy use analysis with standard measures and savings potential calculations
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.
What is the primary function of an ISO 50001 Energy Management System?
Answer: To provide a framework for organizations to improve energy performance through policies, objectives, and targets
ISO 50001 provides a systematic framework for continuously improving energy management practices, performance, and efficiency.
In energy procurement, what does 'additionality' mean in the context of corporate renewable energy purchasing?
Answer: The purchased renewable energy results in new capacity being built that wouldn't exist otherwise
Additionality means the corporate purchase causes new renewable generation capacity to be developed, maximizing environmental impact.
