- An action designed to achieve efficiency. – plural noun: efficiencies“to increase efficiencies and improve earnings”
- TECHNICAL –The ratio of the useful work performed by a machine or in a process to the total energy expended or heat taken in. “the boiler has an efficiency of 45 percent”
Energy Efficiency simply means using less energy to perform the same task – that is, eliminating Energy Waste. Energy efficiency brings a variety of benefits: reducing greenhouse gas emissions, reducing demand for energy imports, and lowering our costs on a household and economy-wide level. While Renewable Energy Technologies
also help accomplish these objectives, improving Energy Efficiency is the Cheapest – and often the most immediate way to reduce the use of fossil fuels. There are Enormous Opportunities for Efficiency Improvements in every sector of the economy, whether it is buildings, transportation, industry, or Energy Generation.
The Useless Wasting of Energy is truly bad for the environment. Many of the energy sources we depend on, for over 70% of our power generation, like coal and natural gas, can not be replaced and once we use them all up, they are gone forever. However, there is a much bigger problem than just running out of fossil fuels and that is that most forms of fossil fuel energy are the leading cause of climate change, which is causing global warming. The more we waste the more the climate is affected. It is no easy task to solve these problems, but they are the most important ones we are facing and threaten our very existence on Earth. The Problem that data centers must address, is the amount of energy consumed.
A good example of an issue that’s continuing to grow is Big Data. In order for big data to be useful, the ability to process and analyze all the information that takes place in data centers must be fast and have a 99.999% up time. Unless DC’s become more energy-efficient and flexible, the big data trend of consuming more power will end up negating the innovation that’s currently taking place in the sector. Information that’s stored in DC’s is mostly dependent on using fossil fuel-based energy. Cloud-based data centers have a great potential for helping reduce wasted energy but need to put steps in place now to avoid any corresponding increase in energy waste that results from increases in storage.
The way energy efficiency is measured in the data center sector
The PUE Measurement
The PUE ratio indicates how much energy gets applied to computing tasks and information technology (IT) assets are measured by power usage effectiveness. (PUE) ratio. An ideal PUE, one where all the energy was applied to computing tasks, would be 1.0. Studies on the average PUE of data centers have varied, but we know that despite well-publicized PUE’s at a few data centers of barely above 1.0, the average is likely closer to 1.8, meaning that there is considerable room for improvement in data center energy efficiency. On average, with companies and individuals alike, users will access less than ten percent (10%) of the digital information that’s actively stored, in reality much less. When you give thought to the files you have saved over the past 5 years ask yourself how much of that information you saved will ever get re-opened? For the purpose of your discovery, it’s important to note that we refer to data that is being saved off-premises via The Cloud.
Data center electrical distribution equipment is the backbone of the data center, as it provides the power to all of its IT equipment and supporting infrastructure. Many existing data centers rely on power distribution architecture that was developed for previous generations of IT equipment, often exceeding 10 years in age and typically consisting of power cabling, transformers, panelboards, power distribution units (PDUs) and automatic transfer switches (ATS), etc.
Today’s electrical distribution designs are rapidly evolving, driven by needs such as increasing power densities, energy-efficiency, flexibility, and the benefits of minimizing maintenance while retaining reliability. Dramatic changes, such as DC distribution systems, have been explored, but there are some practical and affordable options to significantly improve a vintage data center.
How amigodata Energy Savings Are Determined
There are lots of great software solutions available to handle this measurement. The one item that needs to be addressed and standardized is how consumption is calculates. amigodata does not offer or provide any solution for monitoring since that would be a conflict of interest. The most prudent way to realize savings and get a clear picture of your savings is to determine the total kilowatts used by the entire data center divided by the total number of terabytes stored. This number is adjusted up or down dependent on whether more gear is added or eliminated.
