2. History In 1992 the United States Environmental Protection Agency created Energy Star, a program designed to reduce energy emissions and greenhouse gases by power plants. Energy Star is a voluntary labeling program designed to promote more energy efficient products. This program is estimated to have saved $14 billion in energy costs in 2006 alone.
3. Road to Green Computing There are four main paths on the road to green computing. These paths intertwine and are all vital to help the environment. Green Use – Reducing the Energy Consumption of computers and use them in a environmental manner. Green Disposal – refurbish and reuse old computers as well as recycling them. Green Design – Designing Energy efficient components, computers, servers, and other electronic equipment. Green Manufacturing – manufacturing equipment while leaving a minimal footprint.
4. Approaches to Green Computing Algorithmic efficiency Virtualization Terminal Servers Power management & Power supply Storage Video Cards & Display Operating System Issues
5. Algorithmic efficiency The Efficiency of algorithms is used to describe properties of an algorithm relating to how much resources it consumes. Algorithms are the base of any computing system or electronic device, each and every computer chip has a certain algorithm that allows it to complete its function. Even though these chips are small, they use a lot of power.

7. Power Supply & Management The ACPI allows control of all a computers components through the OS. This allows your computer direct control of all its systems, turning off components whenever your computer goes to sleep or hibernates. Knowledge and use of identifying power-hungry components and reducing their power usage when not needed, can help the environment significantly.
8. Video Card & Display Video cards alone take up a lot of power. They need to because they processes huge amounts of data in seconds, converting electrical impulses into other electrical impulses that a display can use.
