ENERGY STAR products are independently certified to save energy without sacrificing features or functionality. Saving energy helps prevent climate change. Look for the ENERGY STAR label to save money on your energy bills and help protect our environment.
Improving your home's energy efficiency with ENERGY STAR can help to lower high energy bills, improve comfort and reduce greenhouse gas emissions. Learn about the many ways to save in your home and track your progress with "My ENERGY STAR" - your new dashboard to savings.
A new home or apartment that has earned the ENERGY STAR label has undergone a process of inspections, testing, and verification to meet strict requirements set by the US EPA. ENERGY STAR certified homes and apartments use significantly less energy than typical new homes and apartments while delivering better comfort, quality, and durability.
Learn and implement global industry standards for data center energy efficiency measurements, metrics, and reporting conventions here. The document also contains contact information for industry leaders participating in the global task force.
Global leaders within the data center industry developed a consistent set of global metrics for measuring energy efficiency and greenhouse gas emissions. This protocol provides the agreed-on measurement protocols for PUE, Green Energy Coefficient (GEC), Energy Reuse Factor (ERF), and Carbon Usage Effectiveness (CUE). This document, dated October 2, 2012, also discusses agreements that have been reached to date.
This document includes the established protocols for measuring Power Usage Effectiveness (PUE) at data centers, based on global industry guidance. The document establishes a standard set of metrics, indices, and measurement protocols which aim to improve data center energy efficiency globally.
In response to a 2007 Congressional request, EPA developed this 133-page report to assess current trends in energy use and energy costs of data centers and servers in the U.S., and to outline existing and emerging opportunities for improved energy efficiency. It provides particular information on the costs of data centers and servers to the federal government and opportunities for reducing those costs through improved efficiency.
