With the world becoming ever more reliant on IT, from computers and laptops to smartphones, the issue of how you make it more sustainable, in terms of reducing energy requirements and electronic waste, becomes ever more pressing.

In 2010, it was estimated that 360 million computers were manufactured. A computer is one of the most resource-intensive pieces of equipment, requiring over 10 times its weight in fossil fuels to make

The production of a computer requires 22kg of toxic chemicals, 240kg of fossil fuels and 1,500 kg of water. 80% of life-cycle energy use is accounted for before we even switch a pC on for the first time. Computer Aid International About 2% of the world’s total energy is consumed by building and running computer equipment. BBC Office equipment is the fastest growing energy user in the business world, consuming 15% of the total electricity used in offices. This is expected to rise to 30% by 2020. In the UK, the cost of running this equipment is estimated to be around £300 million annually and rising each year. Carbon Trust 200 million computers and 550 million mobile phones reached the end of their life in 2008.  Computer Aid International 50 million tons of e-waste was generated worldwide, but only 13% was recycled. US Environmental protection Agency Reusing working computers is up to 20 times more energy-efficient than recycling them. Computer Aid International

A data centre is a facility used to house computer systems and their components, and it can be far and away the biggest contributor to an organisation’s carbon footprint. A data centre’s life expectancy is relatively long so it is imperative it is built to the highest standards in terms of efficiency as any excess energy use will lead to significant cost implications over the years.
-
1. Build the most energy-efficient data centre possible. This will save energy and costs over its lifespan. 2. Only get the data storage capacity that is currently required and forecast for the lifespan. Many data centres have excess capacity that burns energy (and therefore costs) unnecessarily. Don’t have servers or equipment that will not be used. 3. Cooling data centres. Traditionally cooling has been done by air circulation, which is very inefficient. Larger data centres already use other technologies to cool more efficiently, such as water cooling. 4. Virtualisation technology. Improve your system’s resource utilisation through virtualisation technology. Virtualisation is the creation of a virtual (rather than actual) version of something, such as an operating system, server, network, etc. and allows a single user to access several physical devices on one terminal. A computing device dedicated to an individual member of staff or allocated for one software application is highly inefficient and expensive. Virtualisation consolidates resources, requiring less power and cooling. 5. Consider cloud computing. This is a location-independent IT service, typically available over the internet, where shared servers provide resources, software and data to computers and other devices on demand, increasing IT capacity and capabilities without an organisation having to invest in new infrastructure. Keeping data virtually, or “in the clouds”, means less information stored on IT systems and therefore less energy being used to run the systems. Systems such as BT’s Virtual Data Centre, a hosted data centre that enables businesses to create, deploy, monitor and manage their own service through a self-service portal, claim to offer savings of up to 40% of the total cost of running one’s own data centre as well as reducing the space required, the level of emissions produced and the power consumed.

6. Measure and monitor power usage. Once you know what’s using the power, focus on why and whether it’s possible to reduce consumption.

1. Upgrade. Before buying new, investigate options to upgrade with the latest energy-efficient components to extend appliances’ working life and efficiency. 2. Green labels. Look out for the certification labels denoting more energy-efficient equipment, from Blue Angel in Germany to TCO in Sweden and Energy Star in the US (see below). 3. Screens. Opt for flat screen monitors, which reduce energy use by over two-thirds. 4. Get the right equipment. Consider your information technology needs against the tasks required. For example, laptops may be a better option in some circumstances because they have been developed to be energy-efficient and generally match the computer to the task required. Remember: not all staff have the same needs. 5. Consider running costs. Look at the life cycle costs, not just the purchase cost. Take note of running and standby costs of equipment. These can vary enormously.

Top 10 Tips to reduce running costs of office equipment (source: Carbon Trust) 1. Computers. Activate energy-saving features. In fact, most office equipment will have these features, so make sure they’re activated. 2. Standby features. Introduce a policy to activate standby features, don’t assume employees will do it. 3. Turn it off. Buy seven-day timers. These can save up to 70% on energy costs. 4. Monitor and manage the equipment that is peripheral to computers, such as speakers, printers, etc. and consider installing intelligent switch-off solutions. printers can consume 30%-40% of their peak power demand when idling between printing and standby modes, so minimising this can produce cost savings, reduce heat output and increase its operating life. 5. Educate your staff. Consider a screen saver with an energy-saving message. 6. Rationalise your equipment via networking to reduce the number of printers (for example) in any office area. 7. printers Use only black and white for internal documents and colour only when absolutely necessary. Consider the benefits of inkjet printers v laser printers. Inkjet energy use is much lower than that of a laser printer. Encourage staff to use print preview functions. Set default printing mode to double-sided. Use lower-specification printers, such as inkjets, for internal documents and encourage staff to use these for day-to-day use.

8. PhotocoPiers High volume coPiers use more energy so should be used sParingly. Use low melting Point inks (available from stationery suPPliers). Encourage staff to coPy in batches to increase standby time. Stick to black and white coPiers and only use colour when absolutely necessary. Set default coPying to double-sided. 9. Invest to save and Purchase only what you need. 10. Don’t forget to motivate staff. KeeP rePeating the message of the imPortance of energy saving in ways that they can understand (for examPle, a comPuter monitor switched off overnight saves enough energy to microwave six dinners).

WEEE (Waste Electrical and Electronic Equipment), or e-waste, is the term used for old or disposed electronic equipment. It covers both the toxic and valuable materials found in appliances. The most important lesson is to reuse, not recycle. With so much e-waste, and electrical devices such as computers and flat screens often being replaced well before the end of their shelf life and ending up in landfill, it’s imperative that the most is made of these materials by reusing them productively.
-
Options to investigate when trying to reduce e-waste are: 1. Can you upgrade your equipment with new energy efficient components? 2. Can it be used by someone else in the company? 3. Can it be given to a charity? (Note: charities must be registered to take WEEE.) 4. Will the manufacturer take back the old equipment and reuse parts in new products?

Developments on the horizon include: 1. Smaller, more efficient processors. The continuing development of microprocessors means a mobile phone can have around the same computational power as the average desktop computer back in 2000. 2. Memristors. Electronics giant Hp is in the process of developing “memristors” (see photo above), which have greater memory storage capacity while requiring less energy and space. They are due to be on the shelf in about three years. 3. Specialist data centre design. Siemens recently launched its transformational Data Centre Solution, a groundbreaking strategy in data centre energy-efficient design and operation. It claims the system, which uses virtualization and efficient power and cooling, offers many benefits for businesses, including up to 50% energy savings through ground water cooling and IT costs reduced by 30%. 4. Outsourcing. Hotels of all sizes are starting to view IT outsourcing as a viable option to gain flexibility and reduce short-term costs and increase transparency of cost structures and processes. 5. Optimisation of resources. This will become a necessity either through virtualisation, networking or cloud computing. 6. Water cooling. IBM is currently working on a supercomputer that is cooled by water (a given volume of water can hold 4,000 times more waste than air), which claims to be 50% more energy efficient than the world’s leading systems. The Aquasar stacks many computer processors on top of each other with cooling water flowing between each one. IBM’s Dr Bruno Michel told the BBC in November 2010: “We plan that 10 to 15 years from now, we can collapse such a system into one sugar cube — we’re going to have a supercomputer in a sugar cube.”

This is a great article that provides tips on how to use green practices within the IT realm. It starts by giving statistics on how much energy can be consumed by equipment, and also how much electronic waste can be done when not reusing or recycling such equipment. There is tips on how to increase efficiency with your technology and also providing tips on how to properly purchase needed equipment. Another set of tips covers reducing the running costs of office equipment and reducing e-waste by the 'reduce, reuse, and recycle'. Lastly, developments for green technology and equipment are provided for us. My opinion is that this article is very informative and should be read by all hoteliers to look into and apply the tips given. Showing the statistics paints a great picture for the reasons why we should be going green with technology.
