Green Search Engines?

A recent newsletter from Ideal Bite discussed ways of saving energy online.

Some engines have a dark background color instead of white, which when viewed on older, CRT monitors consumes 20% less energy than typical engines. Who knew?

Their advice...

Blackle - an unofficial black version of Google that uses less energy than the white version on some screens (for a more colorful option, try The Green Spider).

Green Maven - this Google-based search engine yields results from green-related websites only.
