“ICF International”, now why does that sound familiar?

IT World

^That sounds bad, but what does it mean? McAfee's report didn't provide an estimate for the daily energy usage of a PC or server, or the energy consumed by other applications. Without these numbers, it's difficult to put the spam energy numbers into context and understand their significance.^
.
^The report also failed to detail the methodology and assumptions that ICF used to arrive at these numbers. For example, the report doesn't say what researchers expect computers to be doing if not being used to filter and read spam e-mails or how this energy could be used for alternative applications. Depending on assumptions like this, it's possible that computers could be used for tasks that consume more power than applications that fight spam^

And you have wonder if they took into account that 25% of our electricity comes from non fossil fuel sources.

The “report” is very much like the example of the annual carbon footprint of 100w light bulb…… left on 24hrs a day for 365 days
