June 29, according to the latest report from the US Department of Energy Lawrence Berkeley National Laboratory, thanks to better cooling and power supply strategies, better power management and cloud computing, data center energy consumption has been brought under control.
After 10 years of rapid growth in energy consumption in the U.S. data center, it began to stabilize in 2010. The report found that since the beginning of its stabilization, only 2% of overall energy consumption in the United States has fallen short of. Expected growth rate of energy consumption will be maintained, is expected from 2010 to 2020, the overall server installed capacity will grow 40%.
According to this trend line, the U.S. data center expects to consume about 73 million kWh by 2020 - about half what the U.S. Natural Resources Defense Council expected last year.
Concerns about the peak energy demand may not come as a surprise, considering the Berkeley Labs report is the first comprehensive data center energy consumption analysis in nearly a decade. A recent report by the Berkeley Lab for the U.S. Congress in 2008 found that data centers use about half of their electricity every five years.
"Our thinking is that in the current year, it is not uncommon for electricity to double every five years," said Arman Shehabi, a Berkeley Laboratory Research Institute. "In fact, tremendous progress has been made in terms of efficiency, but there are still significant opportunities in the short term."
Public concerns about energy consumption are tied to business interests, and public and private entities have embarked on major projects that have made data centers more efficient in recent years - like Facebook's Open Compute Project. Governments and businesses are also exploring the efficient operation of data centers in warmer climates, investing in innovative storage solutions that use renewable energy.
Taking into account the current situation, the United States estimates that energy savings will be about 6,200 billion kilowatt hours by 2010 or 2020, or more than 60 billion U.S. dollars, the report said.
Berkeley Lab's team found that larger data centers have made significant progress toward efficient operations. , They are not relying on air-conditioning equipment to cool their equipment. They rely on "energy equalization" to reduce the server's power consumption when the server does not process as much task. The increase in the use of cloud services is also a factor.
"Data centers were formerly seen as a fixed cost, but which provider won the lowest cost in a cloud environment was one of the easiest to optimize," Dale Sartor at the Institute said in a statement Said.
Although the overall trend is positive, the smaller data centers - which are projected to account for 60% of all data center consumption by 2020 - remain inefficient.
"The growth in this industry is primarily in very large data centers, but there are opportunities for general-purpose or institutional data centers," Sator said. "There are millions of cabinets or cubicles in these data centers, which are inefficient."
