問 5
Incorrectア
An eco-farm is a term from agriculture. It refers to environmentally conscious farming, such as reducing chemical fertilizers and chemical pesticides, or a farm that practices it (a different word from “eco-farmer”, the nickname for farmers certified by the prefectural governor under the Sustainable Agriculture Act). What it covers is farming methods, so it has nothing to do with saving energy in information and communication equipment such as PCs, servers, and networks, or with promoting energy conservation in society through IT.
Incorrectイ
Environmental assessment (environmental impact assessment) is a procedure carried out before a large-scale development project such as a road, a dam, or a power plant. The effects the project would have on air, water quality, noise, ecosystems and so on are surveyed, predicted, and evaluated in advance, the results are published, and the opinions of residents and local governments are reflected. It is purely a system for assessing a project's impact beforehand, not a concept of promoting energy conservation by using IT equipment.
- ウ
正解 The correct answer is (ウ) Green IT. Green IT is the idea of using IT to reduce environmental impact, and it has two main aspects. The first is Green of IT, which means making the IT equipment itself environmentally friendly: lowering the power consumption of PCs, servers, and network devices, improving air-conditioning efficiency in data centers, cutting the number of servers through virtualization, and using resource-saving design and recycling. The second is Green by IT, which means using IT to lower the environmental impact of society as a whole: reducing how much people travel, and the fuel that transport burns, through telework and web conferencing, reducing paper use by going digital, and cutting wasteful transport and inventory through demand forecasting and logistics optimization. The question says not only energy saving and effective use of resources in information and communication equipment, but also promoting energy conservation in society by using such equipment, and this pairing of the two aspects is exactly what decides the answer.
Incorrectエ
Zero emission is the idea of bringing the amount of waste that finally goes to landfill close to zero, for example by using the waste from one industry as raw material for another. Its focus is on turning waste back into resources and circulating it, so it is not the term that explains the two aspects in the question: saving energy in information and communication equipment, and saving energy across society through the use of IT.
ここがポイント
- Green IT = Green of IT (saving energy and resources in the IT equipment itself: lower power consumption, consolidating servers through virtualization, more efficient data center air conditioning, and so on) plus Green by IT (using IT to lower the environmental impact of society as a whole: less travel thanks to telework and web conferencing, going paperless, optimizing logistics, and so on). When a question lists these two aspects side by side, the answer is Green IT.
- Tell confusingly similar environmental terms apart by the area they apply to: environmental assessment = evaluating the environmental impact of a development project in advance (a procedure); zero emission = bringing final disposal to zero by turning waste back into resources (circulation); eco-farm = environmentally conscious farming or farms (agriculture). Green IT is the only one whose subject is IT equipment.
