edit: I guess what I'm wondering is if anyone switched from a desktop to a laptop and noticed a difference in their electric bill.
Posted 30 September 2012 - 01:17 AM
Googling around a bit I found people reporting 25-100 W for a desktop PC idling, depending on hardware loadout. For laptops it seems to be more like 10-15 W. If it's on for 8 hours a day every day, that's around 3 kWh/month for a laptop and anywhere from 6 to 24 kWh/month for a desktop. I don't know about you, but that's only a few percent of my electricity bill (total usage last month: 360 kWh).
My guess is appliances like your fridge, hot water heater, etc. make up a lot more of the power bill than the PC. Switching to a laptop could make a measurable difference, but not a large one.

I have just been bought a new mac book, dual booted with os X and win7
One of my builds is a really big project and takes 15 minutes to build, five minutes of that is really heavy work, both cores hit 100% usage.
When I first got the machine it kicked into power save mode after 10 minutes, totally screwing up the build and causing all sorts of damaged files to be created.
Took me a few hours to fix, and a few more hours to find the right setting to turn this "feature" off.

I would be power conscientious for environmental reasons before my wallet, but often the two go hand in hand. Notebooks are good on power, but the lack of hardware diversity and ease of replacing parts is what turns me off. Had the laptop industry evolved like the desktop industry, I would have stopped buying PCs over a decade ago. Alas, such as it is, cheap hardware and cheap quality at expensive prices is a major turn off. For mobility and even doing Linux builds, I rely on my netbook. Like 5 watts on standby and with Linux console, there's virtually no power draw even under use. I sometimes do long train rides (4-5 hours) and can almost coast the whole way without recharge. It's not for everyone, but I love these little guys.
I wouldn't bother to much on solar power. Most portable packages are gimmicks built with low quality. Better to spend $100 on another lithium battery to extend your use then spend $100+ on a portable solar unit with materials bought and constructed from the lowest bidder. A more versatile setup is to invest in portable battery chargers. They generally come with a high capacitance lithium battery that you precharge. You then plug your devices into it and it acts just like a normal power source until the battery runs dry. About the same in price as a laptop battery, but with more utility.

I was talking about solar for my whole home. It's really come down in price if a person uses a small amount of electricity like I do. I figure I can start out with a 300 watt system with 4 batteries (lead/acid). I plan on using propane for cooking. I burn wood and don't use an air conditioner. I have a passive solar house which somewhat cools in the summer by storing night air and I live in Wisconsin. It wouldn't be actually practical, but I would either break even or only lose a small amount in the long run.

On the other hand, those last six months did include summer. I don't know how much power he'll pick up in winter, but it'll probably be at least a factor of 3 less than in summer, given our latitude. And if you heat your home with electricity then you of course need more power (my electricity usage is over 2x higher in winter). Overall, with his setup I think I could just barely pick up enough power to serve all my electricity needs throughout the year - if I had a way to store the excess energy from summer and use it the following winter. I don't know if batteries can keep a charge for that long, though.

Install wood burning stoves for heating, water heating, and cooking.
I grew up without central heating, a coal fire with a back boiler provided heat and water. An arga burned wood and coal for cooking,
Ok I got used to breaking the ice in the toilet bowl on winter mornings, and we had so many blankets on the bed movement was impossible, but the bills were cheap

In my case, I have three monitors and a big vidcard, so my carbon footprint is relatively-speaking "off the chizzain".

I was totally going to recommend measuring what your power consumption like that, I've done so in a Science class at a vocational school I used to attend. I'd recommend not worrying about what people think about solar powering your house and do it, also look into the haswell cpu next year if your interested in lowering your electric bill, just upgrade your cpu / mobo/ ram, and use the igp. You would be set and it would eat next to nothing. Upgrading from 939 to 1155 cost me $130 but I have 8gb of ddr3 and that was included in the price, your chipset dosen't matter buy a really cheap one, and same with a budget cpu, my Celeron only eats 15 watts when I try to max it out. Also 32 nm is incredible even in a celeron I love knowing it costs next to nothing to have my computer on all the time.
