$this->bbcode_second_pass_quote('MattSavinar', '')$this->bbcode_second_pass_quote('oilfreeandhappy', 'O')verall, I think computers actually save us energy. Examples:
- Use of Internet instead of running to the library.
- Use of disk space instead of paper.
- In-home entertainment instead of going out.
- Shopping on-line instead of the malls (assuming the route-oriented shipping is more efficient than the independent use of the automobile).
There's probably others I didn't think of...

http://home.comcast.net/~oil_free_and_happy/If computers help us save energy, why hasn't energy demand been abated in the last few years as computers have become widespread?
Exactly.
The Internet as it exists today is the product of many decades of technological development, going back to the Z3 and Colossus in the 1940s, the vacuum-tube-based UNIVAC and ENIAC in the 1950s, the development of the graphical user interface at Xerox-PARC in the late 1960s, the invention and development of the modern CPU in the 1970s, culminating in the election of Al Gore to public office which allowed him to create the Internet

, and so on, and thousands of other developments, all of which required hundreds of millions if not billions of man-hours and all the energy use that ensues.
The components of the computer's CPU, sound card, hard drive, modem, network card, the cabling, the monitor, the PLASTIC, all have to be mined, shipped, refined, shipped, processed, built, shipped, assembled, packaged, shipped, and then you finally drive to the store to pick it up, take it home, and plug it in, where it consumes power during the 95% of the time you're not actively engaging the computer's capabilities.
You'd think that I hate computers. Not quite, my relationship with them is more ambivalent. I'm reminded of an old Dilbert:
Dilbert: You dinosaurs have never seen this before.
Dinosaur: What is it? What does it do?
Dilbert: It's a computer. It allows us people to do complex tasks efficiently, and saves us a lot of time.
Dinosaur: What do you do with all the time you save?
Dilbert: We spend it on the computer.
Dinosaur: Wow! Then you save even more time!
