Explainig Green Computing

Impact

• ICT 2% of CO2
• energy costs...
• P.C has 1.8 tons of chemicals

Energy Reduction Saved

• turn off idle P.C
• lower power
• server vertualization
• hardware as service
• energy efficient coding
• in U.S and U.K 20bn kWh a year wasted P.C
• 15 million tons

IBM Project Big Green

• 2900 servers
• 30 mainframes
• 80% savings

• small companies use other things like Amazon uses amazon elasting compute cloud

Electricity decreasing

• energy reduced
• energy efficient coding called cut by 30%

Solution?

• microprocessor = most energy efficient, emission reducing device
• increase business effiiency
• enable demat
• decrease need for travel
• computing saved more natural resources than consumned

Dematerialization

• replaced w/ digtal downloads
• video conferencing

audit of tech to planning after that :
Identify Purchasing Strategy

• buy laptops not P.Cs
• if PCs thin clients
• don't increase specify
• increase efficiency

Maintenance

• set monitor to decrease power mode
• off P.C
• replace CRT w/ LCDs
• extend life of equip?
• rationalize all equip?
• set printer to flip mode

Data Centers

• increase eff. servers
• recycling
