Computer power consumption, while receiving increasing attention, is still a confusing beast. One of the biggest potential power drains in a system could be the video card. This is easiest to explain with this fantastic writeup and chart:
If you have a laptop or desktop with integrated graphics, it is usually fairly low on the wattage and likewise lower on performance, but certainly enough to do all common tasks. Unfortunately, HD video playback can still be a burden for aging systems. With Flash now hardware-accelerated, instead of upgrading a whole system, you very often need not upgrade anything but a video card to keep your system tolerable on the internet.

80PLUS1– This is a rating system for power supplies (PSUs) based on efficiency. In order to meet basic 80+, a power supply must be able to provide greater than 80% efficiency at a number of power loads. However, this does not say anything about efficiency when the system is idling. There are different levels, too (standard, bronze, silver, gold, platinum). Leading to...
Wattage – Unless you're building a “performance” or “enthusiast” type system, your needs are minimal. That said...
Anyone interested in Great Lakes wetland research has gotta check out http://greatlakeswetlands.ca/
This is where the Coastal Wetland Research Group at McMaster University (Hamilton, Ontario) share research on the ecological functions of the Laurentian Great Lakes' coastal wetlands. You can find a variety of publications here - not just McMaster research.
Our own Mary Muter, Chair of Sierra Club's Great Lakes Section has a piece posted there - tho a couple years old it is still relevant. Down the Drain: Georgian Baykeeper battles to save the Middle Lakes
