These two words sounded like oxymoron to me till a few days back. However, with technology, these are possible and sustainable source of convenient living while retaining our Green environment.
Green Plastic is biodegradable and made from renewable resources. Latest technology in this field can also make their production lot more environment friendly compared to current plastic production. These plastics like others are made of polymers, difference however is the kind of polymers used to product such plastic. All these polymers do not have standard renewability index. Since they vary on degree of renewability, there are degrees of green in green plastics.

GREEN Computer Laboratory
While everyone today is focusing on contributing to Green environment, a few are ahead of time and invested time, efforts and money towards supporting this global cause.
I recently stumbled upon a computer laboratory site in Philippines. They have created a solar powered computer laboratory which acts as a computer lab for school children in day time and revenue earning place after school hours. In my honest opinion it is a great idea and a true reflection of the fact that these initiatives cannot be left on governments to follow. Each one of us has to stand up and start contributing to a Greener environment for us and next generations.
Cabilo Island website can provide the details that you may want to see for this project.
Let's all vow towards a greener environment.

Disk Idle Detection
To help achieve maximum system energy efficiency, the Windows power manager cooperates with various software drivers to automatically power down devices when they are not in use. This mechanism called "device idle detection"- allows devices to change their power state automatically based on system environment, power policy, and current device usage.
Although any device can participate in device idle detection, several devices are more tightly integrated with the Windows power manager to help ensure maximum system power savings. The hard disk drive device in a desktop or mobile PC is one device that is tightly integrated with the Windows power manager. On online Microsoft Support fundamentals are given how Device idle detection for hard disk devices involves changing the state of the rotational media within the disk device.
Powering down the rotational media in a hard disk drive is called a "spin-down," and powering up the rotational media in a hard disk drive is called a "spin-up." Disk idle detection is key in achieving maximum mobile PC battery life because the difference in power consumption between the spin-up and spin-down states can be up to 500 milliwatt (mW) on mobile PC form-factor disk devices. The difference in power consumption between the spin-up and spin-down states is larger on full-size desktop PC form-factor hard disk devices.
The Windows power manager uses disk activity, power policy, and system power source (AC/DC) to determine when to spin down and when to spin up the disk device. Microsoft help or windows help contents explain how Power policy configures the time interval between the last disk access and spin-down of the device, as well as any amount of disk activity that should be ignored to be more aggressive in entering the spin-down state.
In addition to power policy, Windows Vista with Service Pack 1 and later Windows operating systems include diagnostic events that allow the system administrator to observe the mechanics of disk idle detection and ensure correct operation. These diagnostic events are displayed and logged by the Power Test utility, which supports various Windows power management test scenarios.
In online Microsoft help that System manufacturers have to configure the disk idle detection policies for maximum power savings or performance accordingly. Also in windows help Support Center or on Microsoft help websites we can see how Power Test utility can be used to validate correct operation of disk idle detection in their pre-installation images.
Disk idle detection is a cooperative arrangement between the Windows power manager and the disk software driver stack. This arrangement helps enable rich configuration of disk idle detection policies and helps achieve maximum mobile PC battery life. The configuration parameters for disk idle detection are stored as discrete power policy values, which change based on system power source (AC or battery power) and the user’s selection of power plan.
OEMs and system integrators can customize the disk idle detection policies to favor power savings or performance. In Windows Help and Support Center and in Microsoft help Center it is explained that how Disk idle detection policies are configured by using the PowerCfg utility and operation of disk idle detection can be observed by using the Power Test utility.

What is Green Computing?
Technology has covered every aspect of our lives. While we are trying to focus on our environment, it will be unfair and unintelligent of us to exclude the device that touches our lives so closely and can contribute to a Greener environment: The Personal Computer.
There are 2 focus areas of computers with respect to envirnment friendliness.:
1. Power Consumption
2. Post disposal utility
There are multiple tools and internet efforts towards educating users about importance of reducing power consumption of computers and contributing towards a greener environment. There are multiple steps that an average computer user can take to save electricity, electricity bills and do thier efforts to make our surroundings greaner. One should use sleep and hibernate modes available through Microsoft Windows operating systems to utilize energy optimally. There are various utilities like ecobutton™, which can help us save energy at the flick of a button. There are other software utilities which can provide help. Edison from Verdiem is a free utility for home users to save energy and evaluate how much they have saved. It also has built in settings to adjust the savings depending on usage.
Another aspect of Green PC is with the recycleability of computers. These computers are refurbished machines, repackaged for use. These are currently meant for low income group individuals. This is another great way of saving our environment. This become more critical as technology enhances and products are outdated very fast. Such recyclability assists in supporting our Green Environment cause.
