1.)Have have green computing efforts lowered the total cost of computer ownership?
Green Computing emphasizes the progress its making in removing toxic materials from all the computers. And for the competitors, green computing is a way to differentiate themselves to comsumers who have come to see green computing as an excellent opportunity to save money through reduced power consumption and to lessen their negative impact on the environment or in other words green computing is a tradition of environmentalism.
2.)Which approach can yield greater benefits - building greener computers or implementing programs that change users' behavior so that they operate their computers in a more responsible manner? Explain your response.
Implementing programs that change users' behavior so that they operate their computers in a more responsible manner. Because as a reliable and responsible computer user , we should already know that whenever we turn on our computers their is many impact to consume energy. To be responsible computer user, we should have time management when turning on the computer and when it should turn it off. We are just using energy and we should use it properly so that the impact to us is not so dangerous.
3.)Do research at the EPEAT Web site and determine which computer manufacturer currently has the best green computing ratings.
Historically, computers have posed a serious problem to the environment. Like other electronics, computers typically contain toxic chemicals such as arsenic, lead and mercury. Computers also typically use massive amounts of electricity, contributing to the energy crisis, carbon dioxide emissions and global warming. Many computers end up in landfills after their useful life cycles are over, despite laws prohibiting such disposal. Fortunately, there are several green technology makers that are making strides toward making greener computers. Even better, these companies are the ones that we all know and trust, such as Hewlett Packard, Dell, Apple and Lenovo. Their green computers and computer-related products are readily available, and they even provide recycling and buy-back programs to help you dispose of your unwanted computers, peripherals and other electronic devices.
In recent years, Hewlett Packard has introduced many Energy Star qualified computers onto the market, including several that have won high EPEAT ratings. For example, the HP EliteBook 2530p notebook computer is Energy Star 5.0 qualified and has earned EPEAT gold. Also, Hewlett Packard has qualified for the Environmental Protection Agency's SmartWay label, which is applied to products and services with reduced transportation emissions. HP is striving to use more recycled materials in its products and product packaging. HP has also instituted buy back and recycling programs for all brands of computers, monitors, printers, scanners and other computer technology. HP has its own huge recycling facility in Roseville, California which processes about 4 million pounds of electronics per month.
