Build an Environmentally-Friendly PC
ThinSkin writes "While gas-guzzling cars are greatly to blame for releasing carbon dioxide into the atmosphere, computers play their role in warming up the Earth too. ExtremeTech has an informative how-to article on building a green PC that will not only help save the planet, but will also slim down that energy bill. An important component, or culprit, to consider is the power supply, so investing in an 80 PLUS PSU is a step in the right direction. The article also discusses how to configure Windows Vista to utilize its power-saving options."
1. The monitor uses a lot of energy, so a laptop is better as it uses a flatscreen panel - or a PC with a flat LCD panel.
2. The power supply on most PCs is designed for a full draw, so it is far better to get a laptop which has a power supply for a smaller draw than a giant 300W PC power supply.
3. Memory is cheaper than CPU, so it is far more efficient to buy a PC with a decent AMD chip that has low power consumption and then cram it full of as much RAM as it can address, than it is to buy an Intel quad core chip you don't really use with minimal RAM. And remember your graphics card has it's own power draw. Basically, RAM is usually 1000 times faster than a hard drive, and can be used for swap files, and to speed processes, so cram it more full of RAM if you want to extend the life of your system and avoid power-intensive disk access. Consider a flash USB drive as well - very low consumption. And use rechargeable batteries for your optical cordless mouse and other devices - ignore the warnings, they work fine.

Several times he said something like, "It's lead free and RoHS so you can throw it away guilt-free!" That's just not true!
RoHS does not equal guilt-free trashing. It attempts to equal a full cycle approach.
RoHS stuff is low lead, true, BUT it is marked with a little trashcan that has a line through it. That icon is telling you DO NOT THROW THIS IN THE TRASH. Have it properly disposed of or return it to the manufacturer. While it contains no lead, it may contain OTHER hazardous materials (eat some no-lead resistors and a slice of PCB, tell me how that makes you feel). It needs to be reclaimed, and NOT end up in a landfill. That's what RoHS is ALSO about.
I'm not a super greenie (I *am* wearing a green shirt) but even I know that trash is a part of the green picture. He had a shred of info about low power and efficient power supplies, but green does not equal guilt-free trashing. Ever.
I'm thinking about it, therefore I might be.
