Green computing, also known as green IT or ICT sustainability, is the use of computers and resources related to it responsibly in the environment. This includes avoiding disposal of electronic equipment and things used in their manufacture. Also, energy saving central processing units, servers and peripherals should be employed and resources used to the minimum. To reduce the undesirable effects of the computers on the global environment, the CPU and all peripherals should be powered down when not in use. The liquid crystal display should be used instead of the cathode ray tube. Paper should be rarely used and its wastes recycled (Gruber, Ralf, & Vincent, 47).
Computers are made of materials that are harmful and toxic. Due to this, companies strive to green their computers by constructing them to work with less power in their performance of essential tasks. This makes the carbon footprint in the planet minimal. Computers are usually constructed from dangerous materials like barominated flame retardant and mercury that are usually average in all computers. In this case, for a computer to be truly green, it not only has to save energy but ensure construction from eco-friendly materials. In 2001, lead free manufacturing of the computers was introduced to improve on greening the computers (Gopalakrishnan, Kasthurirangan, Siddhartha and Soteris, 97).
Computers should be made from less hazardous materials and eco-friendly. The green computers operate in ways that benefit the environment. The Waste and Electronic Equipment Directive ensures that the electrical components disposed are collected and recycled. This minimizes the amount of toxic e-wastes in the environment. The processor manufacturers ensure that the processors consume minimal energy compared to the previous processors. The motherboards also save sixty-eight percent of the energy. The preferred LCD monitors use just one third of the energy that the CRT monitors consume and emit low frequency radiations. These radiations cause harm to the environment and the eyes.
Carbon footprint is the green houses gas produced. This gas is measured in carbon dioxide units. These greenhouse gasses emitted in the environment cover the earth affecting the temperature. Increased concentration of the carbon dioxide, methane and the nitrous oxide contained in the green house gasses increases the temperature on earth. This causes droughts, floods and rise of the sea level. All these effects lead to a fall in the world’s economy. Computers that are carbon free are produced to reduce the amount of carbon dioxide emitted. The microprocessor manufacturers also aim at reducing energy consumption on their products. Companies also strive to green their computers by constructing them to work with less power reducing the carbon footprint in the environment (Velte, Toby, Anthony & Robert, 77).
The Energy Star program was created in 1992 by the United States Environmental Protection Agency. It saves the amount of power consumed by a devise by switching it in to sleep mode when not using it. The power of the devise can also be saved when it is in standby mode. However, the standby mode causes green house gas emission. Energy used by devises on standby are not of use. It is only needed to maintain the memory. Otherwise, this power is wasted power. Energy Star therefore helps the devices reduce this unnecessary waste (Gopalakrishnan, Kasthurirangan, Siddhartha & Soteris, 133).
The China Energy Conservation Program is an organization that administers, manages and guarantees energy conservation, water saving and production of products that are environmentally friendly. CECP encourages producers to produce environmentally friendly products. They also encourage the consumers to make wise decisions when purchasing a product. CECP involves itself in projects in the national and international level encouraging improvement in energy conservation and environment protection (Gruber, Ralf & Vincent, 93).
