Environmental awareness is nothing new when it comes to air and water pollution. How do the computers we use every day in business factor into the environmental picture, and how can being a "green computing" company generate green for the business? While a company owns a computer they impact the environment in several ways. Computers consume electricity, generate heat, and ultimately have to be disposed of.

Going to Green Computing is not only good for the environment, it can save your company some $green$! DeckerWright Corporation helps New Jersey businesses uncover green computing opportunities.

Cloud Computing

Technology solutions are being developed at a rapid rate to provide services for small to medium size business where the processing is "in the clouds". Cloud computing services are available for a variety of software applications with servers residing remotely; email servers, backups and disaster recovery. The remote server management, software licensing and processing power provides a cost effective solution for companies that do not have the need for enterprise level software nor the manpower to support the hardware and software.

Green Computing

A typical computer consumes between 50 to 100 watts of power. With delivered electricity costs in New Jersey at about $0.15 per Kilo Watt Hour a computer can cost several hundred dollars a year if left on. The table below illustrates the cost for running computer equipment continuously for a year for different power consumption levels:

Annual Projected Costs for leaving a computer on

Cost/kWH 25 Watts 50 Watts 100 Watts 150 Watts 200 Watts
$0.15 $32.85 $65.70 $131.40 $197.10 $262.80
$0.20 $43.80 $87.60 $175.20 $262.80 $350.40
In order to determine the actual energy consumption of common computer equipment, DeckerWright Corporation tested the equipment below in its lab to determine power consumption. The power consumption listed is the power drawn while the device is running.
Equipment Description Power in Watts
SonicWall TZ170 Firewall 10
HP ProCurve 24 Port Switch 35
APC Smart UPS 750 (with nothing plugged in) 35
HP L1706 17" LCD Display 50
Viewsonic 17" CRT 100
Dell Optiplex 745 desktop computer 60
Proliant ML110 Server 100
Proliant 3000 Server 230
Proliant DL380 Server 260

Understanding that each device that is plugged in consumes power and having an idea of how much power those devices use is the first step to reducing energy consumption and saving money. Unplugging unused equipment with a total of 200 Watts of power consumption will save a company $262.80 per year. In the early days of computing when computer equipment was expensive, it was conventional knowledge that leaving a computer turned on all the time would be the best thing to do for the life of the computer. In today's world of reliable inexpensive equipment and increasing energy costs, turning off a computer at night and on the weekends can lead to significant savings with no impact on computer longevity. Just turning one PC and CRT off at night would yield over $100 in annual savings!

Another energy saving tip is to replace CRTs with LCD displays. An LCD uses one half the power of a CRT. There is no significant difference between the power consumption of today's computers versus four year old computers, except today's computers have more sophisticated power management features.

The heat generated by computer equipment is often unnoticed. Data centers and equipment closets are typically the places that companies will experience heat related issues. Proper ventilation is the key to minimizing the need for special air conditioning systems to cool data centers. In a recent facility we completed, air handling equipment was installed to distribute data center heat through the building reducing cooling costs by over 25% and providing a "no cost" method to heat the building. Proper design for rooms with high concentrations of equipment must include exhaust vents to remove heat from the space allowing cooler air to enter the space. The most common need for external air conditioning for equipment rooms is lack of adequate venting. Heat generated from a data center or equipment room needs to be planned for and included in the HVAC plan for a building. Intelligent HVAC designs can save thousands in annual costs.

At the end of a computer's life cycle a business must deal with the disposal of the old equipment. Under Monmouth County New Jersey disposal rules, you can not put computers or computer equipment into the garbage, t hey must be recycled. CRTs contain lead, and phosphorus in amounts that make them hazardous waste, so proper disposal is a must. If the computers are still in good working order, there are non-profit organizations that will take the equipment. DeckerWright Corporation facilitates these transactions by documenting the value of the donated equipment for tax purposes.

Here are some options for getting rid of old equipment:
