chapter seven Flashcards
greenhouse effect
build up of CO2 that slows the release of heat into space
green computing
practice of using computer resources efficiently, while reducing the use of hazardous materials, maximizing energy efficiency, promoting recyclability of defunct products and reducing factory waste during the computer’s manufacturing process
chief information officers (CIOs)
in charge of all of a business’s computer assets (millions of dollars in savings by reducing energy)
electronic product environmental assessment tool (EPEAT)
helps large institutions purchase, select, and compare computers based on their environmental attributes
who started EPEAT and who manages it?
granted by environmental protection agency (EPA) in 2006
managed by green electronics council (GEC)
how many criteria are in EPEAT and how many are required?
51 total
23 required
what criteria must you know?
reduction/elimination of environmentally sensitive materials materials selection design for end of life product longevity/life-cycle extension end of life management corporate performance packaging energy conservation
energy star
a voluntary labeling program designed to identify and promote energy-efficient products, like business computers, to reduce greenhouse gas emissions
when was energy star introduced?
1992 by EPA (joint program with US energy department)
what is the energy star’s goal?
to keep chips, motherboards, and other computer components that use far less electrical wattage than conventional computers
what is the most important criteria of a green pc?
energy-efficient power supplies
what is a green pc?
power supplies and processors that consume minimum amounts of electricity
attempting to do away with/minimize environmentally harmful components
make use of aluminum or plastic parts made from post-consumer recycled materials
what are the 3 PC modes?
active use
sleep mode
standby mode
active use
on and being used
sleep mode
low-power mode, certain things are off
standby mode
off
80plus
requirement of a PC to convert 80% of its AC power into DC current
how does Apple attempt to implement green computing plans?
extremely aggressive in reducing/eliminating toxic substances like polyvinyl chloride (PVCs) in manufacturing
how does Hewlett-Packard (HP) attempt to implement green computing plans?
reduce cooling energy by 15-30% and use 75% less energy in sleep mode
how does Lenovo attempt to implement green computing plans?
42 PC models that are EPEAT compliant, many with a a gold rating
how does Dell attempt to implement green computing plans?
25% less energy than just a few years ago
what are green computing business plans consider?
organizational policies and procedures best practice considerations long-term (sustainable) reduction of power usage and paper consumption recycling policies and procedures governmental guidelines
what are tangible benefits of green computing?
economic considerations telecommunicating reduction power usage and paper consumption recycling policies and procedures governmental guidelines
telecommunicating
work arrangement in that employees benefit from flexibility in working location and hours (reduces carbon footprint)
