Brazilian plans to encourage lower energy use amid an ongoing drought include a mandate to federal data centres to moderate their power use.
This came after news a few days ago that Brazil was looking at measures to encourage less energy use as the country struggles with its worst drought in nearly a century.
Reuters reported that the measures would aim to lower the country's electrical load and reduce demands on the system. The alternative could be energy rationing.
Among the measures announced in recent days has been a government mandate that federal data centres should use less energy. The decree says data centres should only cool data rooms “to the limit of what is technically necessary”.
According to the Data Centre Dynamics website, the mandate also suggests, among other things, that air conditioning equipment should be dimensioned according to the size of the environment; lighting in places not used must be switched off; and electronic equipment – including computers, monitors and printers – should be set to consume the least amount of electricity possible when not in use after a few minutes.
The decree also requires agencies to buy the most energy-efficient equipment, follow energy efficiency standards for new or renovated buildings, and perform preventive and predictive maintenance on equipment.
Of course, this decree focuses only on federal data centres, but it does highlight the energy demands of data centres in general. Most data centres now at the planning stage have some level of energy efficiency planned in. But with so many now being built, could their energy demands be a long-term problem?
