You may recall several months ago the media frenzy around the carbon footprint of a Google search
. One scientist performed a calculation allocating about 3.5 grams of CO2 per search, a figure which Google hotly contested.
One search engine, Blackle
, reduces this impact by simply making the screen all black with white letters, a simple feature which (according to their counter) has saved over 1.2 million of watt-hours of electricity to date.
Now a bevy of new green search engines is pushing the carbon-free searching envelope by contributing directly to the environment each time you search. A great top 10 list of green search engines
was put together by Saikat Besu of MakeUseOf. Some of my favorites:
saves 1/10th of a meter of rainforest (about 4" x 4") per search, so in about 40,468 searches you could plant a whole acre. I probably do about 20 Google searches per day (7,200 per year) so in about 5 1/2 years I would save a whole acre of rainforest. Forestle does their rainforest protecting through a partnership with The Nature Conservancy.
is from the same company but uses Google instead of Yahoo, and instead of rainforests they carbon-offset their IT energy consumption by using ad revenue to pay for REC's (or Renewable Energy Credits).
Green Planet Search
is less functional but more slick. The website custom aggregates a wide variety of content including news, blogs and products.
curates the top content sources specifically targeting content for the eco-friendly. It has mapped over 10,000 sites and includes 4,000 business listings.
There are a bunch more. Check out the full post
