I knew what you all guys out there thinking. How we going to save huge $ 2.8 billion a year? The answer is just simple. Just shut off your laptop when you are not using it.In total, the total saving in electricity would be the $ 2.8 billion.
According to article titled "Leaving computers on overnight = $2.8 billion a year ", it says 'But all the power wasted while computers are sitting idle overnight adds up, and one study has finally tried to measure it. The tally: An estimated $2.8 billion wasted on excess energy costs each year in the U.S. alone.
On a CO2 basis, that's 20 million tons of carbon dioxide, about the amount produced by 4 million cars on the road.'
Admittedly I don't think much about it at all although I shut off my laptop after i use it. Many people running overnight because I know it'll take five minutes or more to get things going in the morning. The article also stated that if you run a company with 1,000 PCs left on overnight, you can save about $28,000 a year if they are turned off after hours. That's not chump change.
In my opinion, i think that laptop or PC will function better if you restart it regularly, and nightly shutdowns can help you avoid having to suddenly reboot in the middle of the day when you'd otherwise be productive. So even though this is very little, maybe it's a smart idea and ultimately a time-saver too to shut it down after hours after all.
