Apple's new iPad estimated to cost $1.36 per year to charge

post #1 of 35
Thread Starter 
It costs less to recharge a fully-drained Retina Display-toting iPad every other day for a year than it does to run a 60-watt-equivalent (13W) compact fluorescent light bulb continuously over the same period, a new study finds.

According to a study from the Electric Power Research Institute (EPRI), an independent non-profit organization focusing on electricity research and development, Apple's new iPad and devices like it could help lower the high power consumption seen as a result of the Information Age, reports the Associated Press.

As smartphones and tablets become more popular and accessible, the EPRI wondered if the flood of new devices was having a negative impact on power consumption. What the group found was that charging a device once every other day from full discharge costs mere pennies per day, a dramatic reduction from large electronics like HDTVs and PCs.

Testing pitted a variety of Apple's mobile products including the overwhelmingly popular iPad, which has sold over 67 million copies as of April, against other household appliances to project energy use in a "post-PC" era.

?As information technologies continue to change rapidly we see important implications for energy consumption,? said EPRI Vice President of Power Delivery and Utilization Mark McGranaghan. ?These results raise important questions about how the shifting reliance from desktop to laptop to mobile devices will change energy use and electricity requirements for the information age. "

Calculations show that the average energy load of all iPads in the market comes to about 590 gigawatt hours per year and if the number of iPads tripled over the next two years the electricity needed could be handled by two 250-megawatt power stations running at 50 percent.

The third-generation iPad, which sports a high-capacity 42.5-watt-hour battery, uses less 11.86 kilowatt hours of electricity over a one year period, a stark contrast to 42? plasma television which consumes 358 kWh. An average laptop consumes 72.3 kWh while a 60-watt CFL light bulb eats about 14 kWh, costing an average $8.31 and $1.61 a year, respectively. Cost will obviously vary by location but for reference the EPRI experiment was conducted in Knoxville, Tenn.

With a weak economy driving more people to energy-efficient devices, the U.S. government expects residential power demand to fall for the third straight year. As devices get smaller and the components more efficient, energy costs are likely to decrease in the coming years especially with more users moving away from PCs to more portable options like the iPad.

That's outrageous!

 

I'll be returning mine immediately and contacting my solicitor.

My car keeps crashing whenever I do 150mph. It's a design flaw. People tell me to slow down and drive normally but I should be able to use it as I wish.

That's great, but even PCs use hardly any power. It's things like Clothes Dryers that put your power bill up.

And it takes a study to find that out?

 

All I need is to read: iPad power adapter, rated 10W. 60W equivalent CFL, rated 13W. Charging an iPad some of the time takes less power than running the other all the time? No shit, Sherlock!

 

Next up: iPad display smaller than 42" TV, study finds.

That were my thoughts, too. How should a device that is charged with a maximum of 10W need more power than a device constantly needing more?

"the EPRI wondered if the flood of new devices was having a negative impact on power consumption."

 

Talk about saying something that means nothing.  Anytime you "add" something to the power grid that consumes energy versus making electricity there is a negative impact.  Windmills included.  I think they better focus their concerns on all these electric cars the green weenies want every one to drive.  I think that'll have a considerably larger impact than a bunch of 10W iPads getting charged every few days...

Just say no to MacMall.  They don't honor their promotions and won't respond to customer inquiries.  There are better retailers out there.

So, my first reaction was "duh, of course the iPad doesn't draw anywhere near 60 watts". And then I realised the "60 W CFL light bulb" in reality was a 60 W incandescent-equivalent CFL lamp. Misusing the SI units in this way is probably way worse than the ridiculousness of the "horse power".

Wow. I did not expect that. I've been being cheap and charging mine at the office, thinking I was getting away with something.

When you're driving one in 20 years, that's what I'll call you. :)

 

BTW, a 60 watt equivalent CFL draws about 14 watts. I don't know why they don't just call them 14 watt bulbs.  ???

An african or european plasma?

 

Seriously, my 42" plasma is on for about 4 hours a week. It's not using 360kWh per year. What a useless factoid to include.

If my math is right, they are assuming 60% average depletion and you unplug the charger when not in use.

Because the average consumer thinks of 'watts' as a measure of light output, not power consumption. If they advertised them as 14 W, very few people would buy them.

The industry is trying to educate people to look at lumens for light output, but it's a slow process.

How long before the environmentalists catch on to this and start condemning people for using a Kindle + house lights instead of using a backlit device in the dark?

Math

60w CFL uses 13w or 113.8kwh of energy per year at 100% use. (13x 365 x 24)

An iPad 3 used 5hrs per day and charged with 85% efficiency uses 8.9 kwhrs per year.

But who leaves a light bulb on all day, every day? Compare it to your tv or desktop or something else.

For the same reason 6mm to 70mm lens on a small sensor camera is marketed as being equivalent to a 36mm to 432mm lens on a 135/Full Frame camera.

They do that because the average consumer doesn't understand the math and the whole equivalent stuff naturally. In their minds they were using 60W bulbs and you want them to use 14W and that means less light etc. So they mark them as 60W equivalent to get across that it's the same light output.

They said from full discharge, every other day.

I believe this is also due to the fact that the iPad doesn't do a whole lot compared to what your typical laptop does.  Think about all those unnecessary applications that are loaded in the background on some PCs and you wonder why people think their machines get slower with age.

 

But it would make sense to me if they made it twice as thin to give me 4 days of continuous operation.  I mean, come on, yes it's shiny and sleek, but I still can't fold it up and put it in my pocket.

I just looked at Best Buy and the 42" LG plasma they have listed is rated at 140kwh/year.  I don't know how many hours a day they are assuming use on that.  Still, it has a power draw just by being plugged in, same as a computer.  My Mac Mini uses significantly less power at max load and at rest than my old PC did.

Thing with 10 watt power supply costs less to charge than thing with 13 watt power input. Revolutionary!

That's the first thing I thought... "Estimated"?? What genius had to "estimate" that 10W is less than 13W??

Or rate them by light output then by how much energy is consumed.
