According to studies, one « click » for searching the web using traditional search engines (whatever the time needed for this research) consumes the power needed for lighting a low power consumption lamp for one hour. For more information, you may read the conclusions of the IZT Berliner Institute and also to this article on « La Vie Numerique ».
We started on the premise that each internet activity has a cost and an impact on the environment. We, as users, are not aware of our power consumption, and therefore our carbon footprint, when we simply « click » on some hypertext links.
And this is precisely the purpose of that Internet site. We wish to help Internet users become a force to count on when the big companies of the web think about their environmental policy, and, for those being trully concerned, we will bring them our search traffic.
Our website is a « meta search engine » with the objective to give you access to the major search engines. We propose to launch your search automatically on the engine which seems to be the most concerned about carbon footprint and earthcare and yet efficient and reliable.
The awareness of the environmental impact of our internet activity makes us try to have a carbon neutral philosophy for 
.
We have decided to be hosted by a carbon neutral company. It was not easy to find, either because of the poor clarity about carbon footprint of the different offers, or because of the costs which can vary by as much as 200 per cent.
Finally, we've choosen to be hosted by ThinkHost inc.ement which has clearly adopted a carbon neutral policy :
« By purchasing the green certificates (90% wind/10% solar), the electricity generated by these sources isn't routed directly into our various premises. We still pay all our bills as per usual to our regular providers - but for every X kilowatts worth of green energy tags purchased, X kilowatts less electricity is fed into the grid via non-renewable means. The solar/wind generated electricity we purchased simply goes into the grid, in our case, Portland's. Still, the result is the same - carbon neutral web hosting. »
From the very beginning of our adventure, we integrated a power saving philosophy.
The design of our « meta search engine » was done in order to lower the power consumption of our screens (CRT). For such a monitor, the darker it is, the less power it needs.
This could seem insignificant, but we hope to draw millions of visitors through our website !
For this reason, instead of simply redirecting the traffic from the original search engine, we display the results using our « low consumption » webdesign
For those having LCD display, the power saving was not measured, but we think that our graphic design is resting for our eyes.
Another important difference between us and the majority of other « metasearch engines » is that we only make one research on one engine at a time. This is based on the fact that the first pages of the different general search engines contain more or less the same results. Doing like that, we don't duplicate the power consumption needed for a search by the number of search engines. And the efficiency is much the same.
NexusClean : Clean Link
The logo :
redirects your search request automatically through one of the search engines which we have rated among the most concerned about environmental care.
Thanks to you, hopes to become a key partner of the major search engines companies as regards environmental issues and their own environmental policy.
In order to achieve this goal, we are creating a process that we'll call the « green ring ».
as your favorite search engine, YOU will give us the means to make it increasingly reliable and powerful. We need YOU to get everything started. Without YOU, our action is pointless.
We want to promote individual awareness and create a collective force.
NexusClean is a tool for everyone, even the more skeptical. Therefore, we've created a «members area» where you can customize your prefs.
Each registered user can set up their preferred search engines for each kind of request (web pages, images, ...). Once recorded, 
will do the search using your preferred engine, but we will display the « green level » of your choice in order to keep you informed.
Environmental care should be a choice, not an obligation.
Here are some of the importants criterias for .
