The Case for Greener Businesses

Introduction

While many people equate fossil fuel consumption primarily with automobile and other means of transportation, by far the greatest contributor of greenhouse gas emissions is gas, oil, and coal-fired electric generators.

meanwhile, the demand for electricitycontinues to grow, worldwide. Estimatesare that global demand will increase 2.3percent per year, on average, from 2010throughtheyear20501.Whilethisincreaseseemsmodest,itwillmeanafurther300%increase in greenhouse gas emissionsgiventhecurrenttechnologiesandpowergenerationtrends.

As a result of the dangerous increase ingreenhouse gas emissions, governments,corporations,anddevelopersareinvestingmoreandmoreresourcesintoshort-termcleaner energy solutions such as cleancoal,safernuclearpowerplants,andhigherefficiencynaturalgasalternatives.Longer-term clean energy solutions includerenewablepowerresourcessuchaswind,solar, geothermal, and tidal generation,all of which are also undergoing large-scale research, development, and initialdeployment. Regardless of whetherpower generation is provided by cleaner,short-term generators or by renewablepowertechnologies,thecostofelectricitywill continue to rise with demand.To keep prices low and supply plentiful,businesses and governments cannotsacrifice the environment for short-termeconomic gain, yet they also cannothamper their economies by eliminatingjobsthatrelyonabundantpower.forthesereasons, businesses are seeking waysto use energy more efficiently, therebyhelpingreduceoverallpowerconsumptionandcontainrisingenergyprices.

Companies worldwide are asking: How do we cut energy costs, reduce our carbon footprint, yet continue to grow our business?

Energy Efficiency Creates Competitive Advantages

The bottom line is threefold: Energy-efficient businesses save money and protect the environment, but are also strategically positioned to outperform their competition.

Besides the obvious environmentaladvantages to reducing fossil fuelconsumption,lowerexpendituresonanyenergy have an immediate effect on acompany’sbottomline.Infact,companiesshould view energy efficiency as acompetitive business advantage as wellasacost-savings:theCaliforniaEfficiencypartnership found that companies thatemployenergy-savingstrategiesintheircompaniesoutperformtheircompetitorsby 10 percent2. This higher productivitylevel goes beyond simple cost-cutting.Companies with proactive energypolicies are more motivated and betterstrategicallypositionedthancompetitors.

According to a report by industryanalysts, businesses must begin to lookat cost management in a far broadersense, incorporating comprehensiveenergy management. from the intenseelectricity demands of data centers tomanufacturing shop floors, businessescangainstrategicmarketplaceadvantagewithbetterenergymanagement.

Bottom line savings in energy are thedirect result of these comprehensiveenergy management plans, butcompanies that strategically streamlinetheir facilities and businesses to bemore energy efficient are also likelyto find additional infrastructuresavings. moreover, all these savings arecompounded every month and everyyear, making them exponentially moreprofitable than their competitors overtime.Inshort,smartenergymanagementleadstohigherprofits.

Companies that ignore their carbonfootprint and energy expenditures areless productive and less profitable. Oneof the first steps companies can maketo improve energy management andcan potentially save billions of tons incarbonemissionsworldwideisimprovedinformation technology services,accordingtoanalystsatpikeResearch.

Teleconferencing

The main objection to teleconferencing,however, is the lackofclear,crispvideoconnections between participants.

Data Centers


Cloud Computing

Inthemostefficientdatacenters,computingresourcescanremainhighlyunderutilized.for example, even in the busiest datacenterstypicalserversareonlyrunningat30percentcapacity.Diskdriveusageandrouter capabilities may also be far below50 percent utilization. In essence, thatmeansthateveryserver,computer,router,or peripheral is consuming energy whilesitting unused and idle. Cloud computingis specifically designed for higher andutilizationoftheseresources.

Cloud computing extends the energyand resource efficiencies of data centerseven further by sharing its resourceswith multiple companies or divisions atone time. The servers and storage are

then better utilized than when used byany one company. furthermore, cloudcomputing can time-shift its resources,accommodating companies and workersfromvarioustimezonesandhandingoffitsresourcesfromoneshiftofworkerstothenext. According to independent analystsat pike Research, widespread adoption ofcloudcomputingcouldreducedatacenterenergyconsumptionbyasmuchas38%by20205.

Although cloud computing is especiallyeffective in reducing energy consumptionand resources, it also has additionalsecurity, maintenance, and other inherentcost-savingsbenefits.

In the most efficient data centers, computing resources can remain highly underutilized.

Reduce your carbon footprint as well as your

equipment expenses.


Tata Communications’ Cloud Computing

Companies that deploy cloud computing as an alternative to traditional premises-based computing reduce energy consumption through the elimination of under-used computing resources and by helping to fully utilize cloud-based resources among many users.

• Lower energy costs and smaller carbon footprint

• Full utilization of resources, less waste

• Use when needed, not always on

By using a technique called virtualization, Tata Communications’ cloud computingallows multiple companies to securely share servers, storage, computer memory,andothernetworkservicessothatfewertotalcomputingresourcesarewasted.forexample,onsatelliteorcabletelevision,multipleprogramssharethesamedeliverysystemratherthanacableordishforeachbroadcaster.Similarly,cloudcomputingcustomersshareTataCommunications’cloudfacilitiesanditscomputingequipmenttomaximizeutilizationwithoutsacrificingperformanceorwastingenergy.
