How your iPhone guzzles more energy than your fridge
Your iPhone guzzles more energy than your refrigerator.
iPhones burn through significantly more energy than a new mid-sized refrigerator, according to a new study. The average new mid-sized refrigerator uses about 322 kilowatt hours a year while your iPhone uses about 361 kilowatt hours annually. The majority of that energy isn’t used to charge your battery, it’s used to power data centers responsible for the wireless connections and data streaming that bring your device to life.
This revelation was made in ‘The Cloud Begins with Coal: Big Data, Big networks, Big Infrastructure and Big Power,’ a paper published by the technology investment advisory Digital Power Group.
The world’s communications systems use 1,500 terawatt hours – 10 per cent of global energy and as much as Germany and Japan combined, according to the paper. The usage is equal to total global electricity usage in 1985.
Just one terawatt hour is enough to power roughly 90,000 homes for an entire year.
With more and more devices being ‘smart’ or ‘connected’ each day, hourly internet traffic is expected to exceed annual internet traffic in the year 2000, the paper says.
A lot of energy is needed to power the world’s communications backbone, and a lot more is going to be needed in the future as more and more server farms are fired up to stream Netflix to whatever is in your pocket, backpack or purse.
By 2035, only slightly less energy will be needed to power ‘the cloud’ than for lights, the paper estimates.
It takes more energy to stream a few episodes of Breaking Bad to your iPhone than it does to stamp them onto a DVD and ship them to you, according to the paper.
One of the world’s largest consumers of cloud data, not surprisingly, is Apple, and it takes a lot of juice to handle all those iPhones and iPads.
Unfortunately, the bulk of this energy comes from coal, over 55 percent in Apple’s case, according to Greenpeace.
‘Coal’s dominance arises from the importance of keeping costs down while providing ever-greater quantities of energy to the growing economies, and as the IEA recently noted, the absence of cost-effective alternatives at the scales the world needs,’ says the paper.
As long as coal continues to be the world’s cheapest source of energy, it likely will also be the most used, further contributing to global warming. Since global data usage isn’t going to drop, Apple might have the answer.
Apple is working towards using 100 per cent renewable energy, and is already 75 per cent of the way there, according to its website.
Using solar, wind, hydroelectric and geothermal power sources, Apple has its sights on becoming as close to carbon neutral as possible – other companies should take note.
據(jù)英國《每日郵報》報道,最新研究表明蘋果iPhone手機的用電量大大高于一臺中等體積的冰箱。
數(shù)字能量研究公司(Digital Power Group)的報告顯示,一臺嶄新的中等體積的冰箱一年耗電量約為322千瓦時,而一部iPhone手機的年耗電量高達361千瓦時。
iPhone大部分用電量并不是用于給手機充電,而是用來支持手機無線網(wǎng)絡(luò)連接和數(shù)據(jù)傳輸服務(wù),否則iPhone手機就無法正常工作。
全球通訊系統(tǒng)每年大約耗電1500太瓦時(1太瓦時=10億千瓦時,約等于9萬個家庭一年的用電量)。這一數(shù)字相當于全球總能耗的10%,幾乎與德國和日本兩個國家的總能耗不相上下,與1985年全球耗電量持平。
目前,煤炭仍然是世界上的能量來源,但是大量使用煤炭卻導(dǎo)致了全球變暖。
