DefinitionGreen IT (グリーンIT) aims both to cut the power consumed by IT equipment itself and to use IT to reduce the environmental impact of business and society.

ExplanationThe former is sometimes called Green of IT and the latter Green by IT. In a data center, cooling uses a lot of power on top of the equipment itself, so the starting point is to measure how power is used and find the waste.

AnalogyIt is like replacing home appliances with energy-saving models to lower your electricity bill, while also ordering online to cut down on shopping trips by car. You reduce both your own consumption and that of your daily life as a whole.

Memory hookGreen is the color of the environment. Remember the direction by the preposition: "making IT green" (of) versus "making society green with IT" (by).

DefinitionGreen IT (グリーンIT) is the idea of reducing environmental impact from two sides: making IT equipment itself save energy and resources, and using IT to save energy and resources across society as a whole.

ExplanationThe first side cuts the power that equipment consumes and the resources that go into its parts, while the second uses IT to cut the travel of people and goods and the use of paper and similar materials. It can be seen as putting the environmental part of CSR into practice in the field of IT.

AnalogyIt covers both replacing home appliances with energy-saving models and using appliances wisely to cut the whole household's electricity and gas use.

Memory hookGreen is the color of environmental protection, so the term reads as IT with an environmental viewpoint added.
