Energy 101: Energy Efficient Data Centers



Data centers provide mission-critical computing functions vital to the daily operation of top U.S. economic, scientific, and technological organizations. These data centers consume large amounts of energy to run and maintain their computer systems, servers, and associated high-performance components—up to 3% of all U.S. electricity powers data centers. And as more information comes online, data centers will consume even more energy.

The History of Automation

Mankind has always tried to use technologies in order to improve his life. The wheel, for instance, was invented in order to transport goods saving forces and to move more quickly. The discovery of fire helped to heat him and to defend himself from wild animals.

From the very beginning man has always looked for a better way of life. Time after time, he has continued to improve his environment, both at work and at home.

The first automations in fact were born in the factories, where at the end of the 19th century the first applications of electricity permitted to make some automated operations, without the intervention of a human being.

Slowly then there has been a shift from manual jobs to automated jobs, from simple tools relied to the ability of a person to process chains controlled by programmable controllers.
That's why many jobs disappeared and new ones were born,and others have completely been transformed.

So automation is whatever permit to make a sequence of automated activities, often in a faster way. And this idea was born in the world of industry. Here in fact there was the need of helping the worker taking him away from repetitive and depressing jobs: as a consequence automated machines and technologies have been developed, so that the way of working in a factory completely changed and the manual factory became automated.

Just think for example at the automobile industry: production times have been deeply reduced thanks to automated production chains, based on sophisticated machineries handled by programmable controllers which control all the production chains without any human intervention.

Calibration Service Keeps Your Machines in Top Notch Form

The importance of calibration service cannot be undermined when it comes to bringing your machines and equipments back to their original working form. This process helps you align your machines with the original manufacturer's specifications. By carrying our regular calibration checks, you can make sure that your machines remain in top notch working condition and you are able to derive a consistent output from them. To ensure this, it is also important to partner with a calibration services provider with a proven track record. Your chosen calibration firm should have all the latest gadgets, machines and know-how to carry out faultless calibration.

Typically, a firm would carry out calibration on-site or in a laboratory and once the machine is fully calibrated, the service provider will also present you with a certificate. These certificates hold a great value especially if you wish to get an ISO certificate or other such industry certifications.

A firm that has an advanced force lab should certainly be your chosen partner. If the company has a temperature-controlled laboratory, qualified personnel and sufficient equipment, you can expect high-quality service and fast turnaround. Alternatively, if you require on-site calibration, you could choose a company that has technicians and field engineers throughout the United States and Canada. These technicians and engineers can provide you accredited Calibration service at your facility.

Following are a few parameters to keep in mind while choosing a calibration service provider:

  • Firstly, take into account the experience of the calibration services provider. Give first preference to a firm that has several decades of experience in calibrating, repairing and certifying machines and other equipment.

  • The true mark of an industry leader is continuous improvement in technology and resources. So if a firm has constantly improved its equipment and procedures over the years to gain an edge over competitors, you can certainly expect satisfactory results that meet or exceed your expectations.

  • Also, it is important to check if the firm adheres to industry standards and certifications. This will ensure that the calibration and repairs carried out by the technicians are at par with global standards. There are certain reputable firms that offer such services all throughout North America.

For companies that need to strictly adhere to government and industry regulations, flawless calibration services have no alternative. Hence, it is very vital to choose a firm carefully. There are certain firms that stick to their commitment of providing continued and consistent training to their technicians and engineers. Imparting theoretical as well as practical training is important for a skilled calibration service technician as they need to know everything about the machines and accessories offered by the company.

Industrial Automation Technology

Industrial Automation Technology refers to the control of industrial machinery and its various processes thus reducing the need for human intervention. Industrial automation technology makes use of various control systems such as programmable logic control, industrial control and numerical control systems. These applications are usually used in concert with information technology systems such as computer technologies that control the automated machinery.

Automation is a step up from mechanization because it greatly reduces the human mental and sensory requirements, whereas mechanization assists human operators with the muscular requirements for the work.

Industrial automation plays a large part in the global economy, and engineers work hard to combine mathematical tools with automated devices to produce better and more complex systems for the expanding applications and range of human activities.

The automation of machines and other technologies has a big impact on a wide range of industries, for example; telephone operators have been mostly replaced by automated switchboards and answering machines, and automated teller machines now make money transactions much easier and help cut down visits to the bank.

Industrial automation is used in a wide range of industries for many different types of application and some of these can include:

o Mechanical engineering

o Industrial controls

o Electronic engineering

o Integrated circuit design
 
o Motion control and fluid control

o Data acquisition software

There are many advantages and disadvantages in the scope of industrialization and some of these advantages are:

o Economy improvement

o Can be used to carry out dangerous tasks

o Can replace tedious human tasks

Some of the main disadvantages are:

o Automation has its limits and at present is unable to replace all human tasks

o Development costs can be unpredictable

o Initial set-up costs are usually high

It is thought by some critics that automation will lead to higher unemployment, yet others argue that the opposite is true and that automation has led to higher employment.

The Growing Need for Renewable Energy

Energy is essential in just about every facet of life and the production of energy is a key factor in ensuring that a nation can thrive and support its self. Traditionally the majority of energy produced is generated through the burning of fossil fuels (coal, petroleum and natural gases). This became a solution for human culture with the advent of the industrial revolution however as the times have progressed the need for alternative forms of energy is become ever more apparent. Limited resources threaten to drive up costs in non renewable energy supplies while creating competition that could lead to warfare. Additionally an ever increasing carbon imprint is potentially leading to environmental instability with the emission of greenhouse gases from burning fossil fuels.

To combat these issues the task has fallen to scientists and technologists to devise and implement a solution that could reduce our reliance on fossil fuels (although losing the dependency of these energy sources all together is unlikely). Clean energy technology has been in development for decades however the implementation of these alternative solutions has not been accepted in the world community as a viable solution due to a variety of issues.

So what is a renewable resource and how does it differ from a non renewable resource?

Development of renewable energy resources utilizes some of the most basic elements of nature which occur across the planet to collect energy that can be reused for human needs. Currently the major areas of focus are in wind power, solar power, geothermal power, hydro power and biofuels. The sun, wind, earth, water and plants are present in just about every corner of the planet Earth making these viable solutions to generating electricity for almost any nation. Non renewable energy resources are those which cannot be replenished naturally (or in the example of petroleum ones which cannot be regenerated faster than consumption demands).

The struggle to attain an energy resource which is environmentally friendly, cost effective and efficient in energy production is the struggle that many individuals worldwide are trying to resolve and the business of the energy industry is in an ideal spot to take advantage of capital gains in this area. An excellent example of the need for environmentally friendly energy can be seen throughout China who has recently become an industrial powerhouse. The use of coal has driven the urban environment into an almost state of emergency in some major cities like Beijing and Shanghai. Air quality levels have plummeted in recent years and health concerns are rising dramatically due to the economic policies emphasized by the Chinese government.

When seeking an alternative energy resource it is essential to take into account the cost of production, efficiency, side effects and economic impact of energy programs. Not all side effects of producing electricity result in environmental catastrophes which can be witnessed in the development of biofuel technologies. While production methods from the wind, sun, water and earth have almost no negative side effects the creation of biofuels exposed an unexpected consequence in the past decade. Government incentives throughout the United States caused many farmers to switch from growing food crops to producing biofuels which led to a shortage of food supplies. Although the shortage did not result in famine or starvation it did drive up the prices of corn temporarily as it was more economically beneficial for farmers to use this in biofuel than for food resources.

The quest to attain the perfect energy resource is one which most likely can only be accomplished by harnessing the ability to gather energy from a multitude of natural renewable sources. Utilizing miniature wind turbines and solar panels on buildings in metropolitan cities is one alternative which looks to be something that may be implemented in large scale programs in the near future.

The need to discover renewable energy resources which can be sustained in a cost effective and environmentally friendly manner is become one of the forefront areas of focus in the energy industry. As energy information is collected into the reliability of production methods such as solar energy, geothermal energy, hydroelectricity and wind energy the implementation of energy technology and policies will most likely change dramatically in the coming decades.

Calibration Of Electrical Test Equipment

Maintaining and ensuring your test equipment is properly calibrated is essential if you are to obtain good and usable results from your experiments. Test equipment machines are only as good as the results they provide and if your machine is poorly maintained and inaccurate then obviously so will your conclusions be.

When you first purchase a brand new piece of testing equipment it should normally arrive with a certificate confirming that it was calibrated before leaving the manufacturers. Throughout the life of the apparatus it is important to have it regularly serviced and maintained and most importantly calibrated. The certificate that comes with re-calibration is your proof of a well-maintained machine and this will work in your favour when qualifying your test results.

A calibration certificate is also useful should you wish to sell any piece of machinery. You are more likely to get a good price if you are able to provide an audit trail, which proves that your equipment has been well looked after and cared for, and that its reliability can be confirmed.

Along with proof of calibration for quality audits and proof that your apparatus meets nationally accepted requirements it will also show the level and professionalism to which it has been calibrated.
When checking on the calibration certificate for a particular machine, especially if you are buying a used or second-hand model, make sure it has the following information: The correct instrument identification number, environmental conditions at the time of calibration, proof that the tests were conducted to a high standard and that there is an auditable, paper trail for the particular machine.

Quite often used models are sold as seen and you will have to pay an additional cost for calibration to be undertaken. Should you require this additional service, make sure you have the correct documentation afterwards.

You can also request a calibration certificate with data. While most certificates confirm the working parameters you may wish to have a copy of the actual data modes and ranges that the machine was tested against. Although tests conducted with data provided give you an accurate indication of the machine's capabilities, the extra information does also tend to cost that little bit extra.

Remember, whether you are buying a brand new test appliance or a second-hand one, or if you are perhaps leasing it, always check to make sure the equipment has been accurately calibrated to produce the desired information you are looking for.

As an engineer, Alex has re-calibrated used test equipment for years. Although his expertise is centred around electrical test equipment, he has been involved with project of many other natures.

Automation Robotics

The main purpose of automation robotics is to optimize the work that has to be done to effectively complete the tasks required to manufacture products. Automation robotics has special purposes, to minimize the amount of time, effort, and energy that is required to produce a product. It is also needed to reduce the amount of waste of raw materials and rework of products that are not completed to specification. Tasks of automation robotics also include the maximization of quality in products that are finished and the safety that is needed in producing them. The definition of automation robotics is not as important as is the understanding of how to apply it to operate in a manufacturing environment for the purpose of making products in the most cost effective and safe way as possible. An engineer who is responsible for creating an automation scenario for a manufacturing company will draw from his knowledge of how robotics are used to accomplish tasks and his ability to apply robotics in an economical way to build an automation solution.

Automation robotics can have the following characteristics:

- an arm that can be configured in different ways
- a number of degrees of freedom which allows movement in multiple directions
- load-bearing capability
- defined work area
- some control system
- a source of power
- repeatability of tasks performed
- accuracy of tasks performed
- reliability in tasks that are performed

Least complex of the robots in industrial applications are those that do lifting and placing. These devices are the ones that do loading and unloading, pick and place, material movements, and palletizing. The ability to move heavier loads and work in unseemly surroundings are characteristics of these machines. Sometimes these devices replace unskilled labor and usually require low maintenance.

The next level of complexity in robots is occupied by the industrial application devices. These do tasks like spray painting, spot and arc welding, tasks that are normally done by skilled labor. A lot of these tasks are harmful to humans because of dangerous exposures that are generated. This type of device requires the ability of servo or spherical control in order to do their assigned tasks. These robots can use training to get their work defined before they are put to the automation tasks. In some cases sensors are used to help give them consistency in their work. Robotics of this type are very good at cutting operating costs and improving the quality of products that come off the production line.

Looking at the top level of complexity in robotics you can see the devices that perform tasks like assembly of products. Consistency and repeatability are high virtues of these devices. Tooling that is at the end of the arm of this devices has the ability to be very precise in placement of pieces in their proper places. These can make minor adjustment in their work to meet the needs of putting products together correctly.

Since it is the job of robotics to optimize the work in the production environment, it is important to define what tasks can best be done by robotics and what task should be best left to human accomplishment. If two tasks in manufacturing are very similar in characteristic, it is much easier to let a robotic move into the new operation, if it similar to an operation that the robotics has performed earlier. The less similar two jobs are the more likely that a human could make an easier transition to the new task. Human abilities accumulate over a lifetime, while the robotic has to start a new task from zero experience and will require extensive training to accomplish it. Robotics do not have any inherent characteristics like humans do. Some humans will better at some tasks rather than other tasks, while different robotics begin a given task from the same starting point that has zero knowledge or ability.

In deciding whether a human or a robot should do a certain manufacturing task there are certain possibilities that might help to guide you to a decision. If the task is too complicated for a robot to perform within economic reason, then the task should be left to a human to do. A robot would win the chance to perform a task if the job was too dangerous for a human to do, or space or other special considerations come into play. If a robot can generate lower cost, better quality, better consistency, or other positives then the robot would win the job.

There are definite decisions that you must make when you are deciding to put a robotic to work in the place of a human. Even the possibility of labor shortage would be a reason for putting a robotic to work.
