A desktop or laptop will typically draw far less power than a single 60W
incandescent bulb. I bet you have quite a lot of those. Even if not, the
CFLs you'll have to give you light at night still draw much much more
than a computer.

If saving energy is your personal driver, then you should be looking at
water heaters, central heaters, aircon and stove as the main culprits.
Everything else, whilst measurable, is a small drop in the bucket and
probably not worth worrying about.

Assuming of course that your computer is a desktop/laptop, and not a 42U
cabinet jam packed full of Dell 2950s
