Energy Mix

Global energy consumption is not stagnant, but growing. And in the past years, it has been growing too quickly for renewables and nuclear to keep up. In the chart here we see primary energy consumption in absolute terms for each source. We continue to produce more energy from fossil fuels – particularly oil and gas – each year.

IT energy management

OverviewServer and data center power managementPC power managementEnergy Efficient EthernetOrganisations and resources for IT energy managementSee also

IT energy management or Green IT is the analysis and management of energy demand within the Information Technology department in any organization. IT energy demand accounts for approximately 2% of global CO2 emissions, approximately the same level as aviation, and represents over 10% of all the global energy consumption (over 50% of aviation''s energy consumption). IT can account for 25% of a modern office building''s energy cost.
