The Energy Information Administration supplies energy usage data.

• A. The energy auditing firm provides usage data
• B. The industrial energy association provides usage data
• C. The energy supplier provides usage data
• D. The Energy Information Administration supplies energy usage data

Answer: (D)

The main idea here is recognizing the official source of energy usage statistics. The Energy Information Administration is the U.S. government’s primary agency for collecting, analyzing, and publishing energy data. It pulls together information from many sources, validates it, and releases comprehensive energy usage data across sectors and fuels on a regular schedule. This centralized, authoritative role makes it the standard reference for energy consumption figures, trends, and outlooks. Private auditing firms, industry associations, or individual energy suppliers may hold useful data, but they don’t provide the broad, official national statistics that EIA continually updates and publishes.
