national center for atmospheric research (NCAR)
global warming has gained ___ and acceptance as an acknowledged problem that will drive business for many years to come.
diffusion
4 watts for a PC and 1.5 watts for a laptop
sleep mode
easy-to-use online tool and helps large institutions purchase, select, and compare computing products.
electronic product environmental assessment tool (EPEAT)
implemented a comprehensive sustainability plan. this plan includes creative eco-friendly measures. one example is that for one week each spring, they fill their nearby fields of their Mountain View HQ with goats. these goats basically mow and fertilize the lawn. this eco-friendly plan has removed the need for noisy polluting lawn mowers and no chemical-ridden fertilizers.
uses 1.43 billion kWh of energy annually but 51% comes from renewable sources like solar, wind, geothermal and biomass.
intel
2 watts for a PC and 1 watt for a laptop
standby mode
tops the list of eco-friendly companies due to its extremely high percentage of employees who participate in telecommuting plans.
cisco
another eco-friendly company due to how they have chosen to acquire power.
intel
initiatives focus on waste and energy reduction. also has a partnership with the World Wildlife Fund which focuses on climate change research, continuing to reduce the use of toxic chemicals in its products.
HP
the person in charge of all business computing assets — he needs to be concerned with overall energy costs associated with computing systems.
chief information officers
50 watts for a PC and 14 watts for a laptop.
active use
started by the Environmental Protection Agency in 2006 and managed by the Green Electronics Council (GEC)
electronic product environmental assessment tool (EPEAT)
informs consumers about special handling needs for disposing of their product when it is no longer useful.
design for end of life
informs the consumer of the percentage of recycled plastic and offers a declaration of percentage of renewable/bio-based plastic material content.
materials selection
asks manufacturers to take their product back at the end of the product’s life, at no cost to the consumer.
end of life management
criteria requires manufacturers to reduce or eliminate intentionally added toxins in packaging.
packaging
encourages manufacturers to make extended warranties available so their product lasts longer or available to be upgraded.
life cycle extension
asks manufacturers to adopt the government’s Energy Star specifications.
energy conservation
means a manufacturer demonstrates a sound corporate environmental policy throughout their business.
corporate performance
started in 1992 as a voluntary labeling program to identify and promote energy efficient products.
energy star specifications
a personal computer that is environmentally friendly and includes the following: energy-efficient power supplies, includes processors that consume minimum amounts of electricity, attempts to do away with or minimize environmentally harmful components, makes use of aluminum or plastic parts from recycled material.
green PC
the most important factor in a Green PC is __.
efficiency
the computer is on and being used.
active use
turns off after a designated period of time.
standby mode
low power after a designated period of time.
sleep mode
converts AC power to DC power, which is typically very inefficient.
PC power supply
Energy Star® standards now require PC power conversion to be raised from 65% to 80%, called the ___. this standard means that less energy is wasted when it is converted.
80 plus standards
claims their computers create less heat and reduce cooling energy by 15%.
hewlett-packard
offers 42 PC models that are EPEAT compliant, all with a Gold Star rating.
