An interesting question environmentally! - I must change to get more views on the control panel.
A couple of weeks back there was something in the papers about the amount of energy used with each click - apparently changing a page is so fast because Google have numerous sites around the world which all pick up the "click" and the fastest to do it is the one you get. Thereby using a lot of power when multiplied by the number of people surfing the net.
Here's a quote I found on a site -
"We concluded that the average page request occupied about 315,000 bytes of data. That’s 2.52 x 10^6 bits. The total energy required for the transaction was 4.6 x 10^-6 Joules per bit. Multiplying these two numbers result in 11.52 Joules. We add in the server energy of 0.02 Joules for a total of 11.61 watt-seconds (Joules) for each page view. Again, this is not streaming video (I’ll look at that in a future blog post), but a static web page access from a server. If you now multiply that single access by 1 million every second (a medium city’s population browsing the web), you get an energy consumption number of around 11.610 kilowatts an hour to keep the data moving... enough energy to power roughly 13 US households for a month! For you viewing 100 pages in a day, that would be about 323 milliwatt-hours of energy - or the equivalent of watching TV for about 10 minutes - an interesting thought."
Now wasn't that interesting? LOL - but still every little bit we can do for the planet helps!!
