Use Ekoru to Reduce Your CO2 Footprint

Ekoru.org is powered by run-of-river hydro-electricity and housed in a datacenter that uses natural convection cooling instead of air-conditioning. This means that our servers don't generate any CO2 emissions. On top of that we have the smallest search pages which means that when the Internet transports the page to your device it generates the least amount of CO2 as well.

A search on Ekoru generates 4.4g less CO2 than other search engines

Comparison between Google and Ekoru based on combination of one search and a results page for datacenter and transport estimated emissions.

2 CO2 emissions of 0.000388g per kilobyte from a 1200KWh server (Tech Republic: Calculating server power usage) processing 0.5Tb of data per month and calculated with US Energy Information Administration CO2 per KWh

3 CO2 emissions of 2.25Kg per gigabyte or 0.00225g per kilobyte for Internet data transport as measured by ACEEE for KWh cost of Internet transport and US Energy Information Administration CO2 per KWh

4 The total combines the CO2 cost of the server in the datacenter with the cost of transporting the page to the user.

5 Only Finland datacentre uses renewable energy

6 Datacenters with mixed power sources or carbon offset programmes are still included in the total as it is not possible to segment mixed power and even if carbon is offset it is still emitted into the atmosphere.
