Green computing. Why should you care?
Quote
Green computing
From Wikipedia, the free encyclopedia
.... San Murugesan defines the field of green computing as "the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment. ...

Why should you care? Don't you want the newest, fester, cheaper amazing new thing with no concern about 'green tech' stuff?
Quote
EPEAT® is the definitive global registry for greener electronics, covering the most products from the broadest range of manufacturers. Only EPEAT combines comprehensive, objective criteria for design, production, energy and materials use and recycling with ongoing independent verification of manufacturer claims after registration. With more than 3,200 products from 45 manufacturers registered in 41 countries, EPEAT has rapidly become the most comprehensive green electronics registry in existence.

everyone upgrades their pc etc through time , but in britain most people recycle them and they are taken apart and disposed of safely but a lot of them go to charities that refurbish them and send them to poor schools in and around Africa. is this done in the countries that fellow members come from

I don't care...

Green movement is just another money grabbing advertising concept and isn't gonna save 1 inbound fresh-water Lake...much less the Planet.

I've noticed your propensity lately to Posting hotly debated political issues and disguising them as news...

Not sure what to make of that...are you just tryin to stir the pot ? ?
Or are you genuinely concerned about "Green Computing" ? ?

If so what machine did you upgrade to recently in your crusade ? ?

Is far as 'Green Computing' goes, i dont think it really matters if you have a green computer.

How much electricity does it take to run the internet?

Google "electricity usage monitor" and you will find a number of gadgets that are designed to monitor individual appliances, including computers.  But since the units cost from $20 to $60 US I'm not sure you will really save anything in the long run.

Much like the "Carbon footprint" nonsense, where companies can throw money at these alleged regulation companies and buy "carbon offsets". What a load of crap. What are they buying exactly? The emissions still go into the air. Giving some organization any amount of money won't "offset" that, and that nonsense where "well, they use the money to plant trees" I don't know about anybody else, but around here, we have too many bloody trees. Everywhere I look. Trees. We don't need more here. Elsewhere? maybe. But what good does planting trees do? Sure, plants consume CO2, but do people seriously think we need to "nurture" poor mother nature back to health? Where do you think the forests came from originally? They developed naturally. leave that clearcut hillside alone for a few years and it will have more trees. planting some trees yourself for any amount doesn't help, because you see them use tons of potting soil, which uses all sorts of machines to sort and grade the soil using machines which themselves give off greenhouse gasses. And do they take into account the water vapour we all exhale when we breathe? Water Vapour is the worst Greenhouse gas of all.

I wonder if I can pay somebody off to get water vapour offsets?

charities that refurbish them and send them to poor schools in and around Africa.

And what do you think happens to the PC's once they die in Africa? Having worked in a few African countries I can guarantee you they don't fix them up and ship to some other poor continent.

You are better off taking a PC to a place that will tear it down and turn its parts into recycled goods that could then get recycled again. If you want to send PC's to Africa buy some new ones and send them.

Agreed, there is to much corruption going on in some African countries. I've seen News stories where food aid has been hijacked by 'bandits', then sold to people. To think this is not going to happen with electronics is daft. I'm not saying that all things get hijacked. I did some work at an RAF base, quite a few years ago, when there was were tens of thousands (maybe millions, i cant remember the details) of Rwandan refugees starving. I've seen the way our 'donatations' get treated. I wouldn't think anything would work if they went through these channels.

This bring to mind all the people that want to use either hybrid or totally electric cars. Yes if we switch to electric cars we won't be using fossil fuels in them as much but on the other hand you have to stop and think about where all the electricity is going to come from to power these cars?

Hydro electric power isn't sufficient enough as the availability to hydro electric power is no where near what it needs to be.

Most people complain when they see big windmills being put up as they either mess up the view that no one noticed until the windmill was put there or they are a hazard to birds.

Just mention putting a nuclear power plant any where with in 1,000 miles of a city and watch how many people complain or threaten to sue some one.

Solar energy just isn't feasible for a multitude of reason. If it was feasible right now there would already be totally electric cars that run off of nothing but solar enegery

That just leaves us with good ole fossil fuels. So go ahead and have every one drive an electric car that way we can pump all the fossil fuels we were using into the additional power plants that we will need to have.

Actually, now t hat I think about it, I truly don't understand the drive to "conserve power" or how,say, your computer using less power will cut down emissions.

It will undoubtedly cut a few dollars off your electric bill every year, but the thing a lot of the penchants don't understand is that no electric power plant "stores" the energy it generates; it generates the power, it goes into the grid, and it either get's used, or not. Wether your computer is taking 650 watts or 1000 Watts doesn't make a difference; for a coal power plant, the same amount of coal will still be burned, and the same amount of emissions will still go into the atmosphere. In fact it's utterly ridiculous to think that using less power directly translates into reduced emissions because First, a lot of power plants don't even HAVE emissions, and second, the aforementioned fact that the power is either used or wasted.

The power that isn't used because of people "going green" isn't "saved", it's wasted. And isn't the entire point of the "green" initiative to reduce waste?

The only incentive to use less power is to reduce your electric bill. Anything else is just superfluous "feel-good" nonsense that gives people a false sense of fulfilling some ecological responsibility.

What makes this most curious for me is that there are in fact people who think that "conserved" power is literally conserved- that it somehow "prevents more emissions" from going into the atmosphere. This is no different then the nonsense about "buying books kills trees". Cutting down the trees kills them. The fact that the tree is then used to create pulp and then paper and then that paper is used to create books doesn't make the purchase of the end-product in any way an acceptance of responsibility for any ecological fallout from the first few; and I might point out also that most of the people that have a problem with paper books seem to have no similar issues with their parent's heirloom dresser or china cabinet. They don't say "sorry father, I cannot accept this; I just cannot stand the guilt of the fine cherry tree that was cut down to make this table". It's nonsense. The tree(s) is/are already dead. Not buying a book doesn't magically save a tree. It just makes you look stupid for not understanding basic logic. Besides, the industries themselves are not evil clearcutting chainsaw weilding maniacal lumberjacks who fell a mountain worth of trees in a single day on their own; trees are this thing known as a "renewable resource". The magic of a "renewable resource" is that they grow back. They aren't gone forever.

I was under the impression that power stations can reduce their output. That they can turn this output up when, say, more people get home from work and turn on TVs etc etc. That they keep the output at a certain level so everybody has enough and they know how much is being used. If the useage goes up then the output goes up. If this is correct (and i'm not saying it is, it is just my understanding of it) the surely if people use less energy then the output will be less and they can burn less fuel to create said electricity.

Hydro plants can control the output. Coal burner plants with strong emissions  can not readily control output levels.  Or the emissions can be worse if you try to improve efficiency. You try to make it better and it gets worse.

Depends on design.

As to solar power, there have major improvements i the past twenty years. Maybe we should all switch to solar pored computers. If you have a panel that can deliver over 300 watts on a sunny day, you could surf in the sunshine and not use a bit of CO2 fuel.

I would use a solar panel installation to charge a battery and use an inverter to get AC, and sell back the excess to the power company. If a 2.2 kW system is eligible to receive the Feed In Tariff it could generate savings and income of around £900 per year, at a cost of about 12 grand. That's a pretty good return at the moment.

The map shows the amount of energy, in kilowatt hours (kWh - the unit that mains electricity is sold in), that a 1 kW array of solar panels angled at the optimum angle will generate over an average year in the UK and Ireland.

Further north, the sun is a little lower in the sky, which means that it takes a longer path through the atmosphere so that less energy reaches the ground. So, in the Shetlands, as you can see, you're going to get less energy than average from your solar array - around 750 kWh per kW per year. But in Cornwall you should be able to generate approx 1000 kWh per kW per year.

Cloudiness also makes a difference, so the east coast of Scotland is a little better than the west coast.

these pc's are refurbished and sent out to a charity with workers from britain , america and elsewhere they also have people who volenteer to go out twice a year for 2 or 3 weeks to fix any pc's that are not working. there are also doctors , teachers , engineers , etc go out as well.

That £900 is averaged out over the year, cloudy days and sunny days. If you know some other way of getting 7.5% tax free on 12 grand I'd like to know about it. Every kilowatt hour of power from a photovoltaic solar panel installation adds £5,000 to the resale value of a home. So you'd get around 10 grand back when you sell. And leccy prices are only likely to go one way... up.

That still did answer the question of what happens to the PC once it dies and can't be fixed. Do these volunteers bring it back home with them to dispose of properly? I highly doubt they do and there are a few reasons for that.

1. Cost - I doubt these people want to pay the cost to ship these back and then pay the cost to dispose of them.
2. Customs - In some African countries it can take any where from 6 to 9 months to get items cleared thru customs so they can be shipped back. Of course this is if you do things the legal way. I can support this time frame as I currently work in supply chain for a major offshore drilling contractor and am based in Angola but also get involved in our operations in Congo, Gabon, Equatorial Guinea, Nigeria, and any where else along the West coast of Africa that we have operations going.

Where did you get this statistic from? The value that would be added to the resale value of your home is going to be totally dependent on the person buying your home. If you sale it to some one that is into solar power great they will love it but if you try to sale it some one that could care less all they are going to see is the extra maintenance cost associated with the solar power system so they aren't going to want it.

How much would the maintenance cost be for a system like you are talking about? This is something that no one ever bothers to mention as people like to make it sound like you just install the system and forget it but you can't do that or it won't belong before you find yourself with a really ugly roof ornament that cost you £12k

2. Customs - In some African countries it can take any where from 6 to 9 months to get items cleared thru customs so they can be shipped back. Of course this is if you do things the legal way.

Off the main topic, but this statement brings back memories of years ago when I did some work in and around Mexico City.  I frequently had to ship, and receive, materials from the US.  Normal time to clear customs was 6 to 8 weeks, but for a few dollars, it cleared in a day.

Where did you get this statistic from?

Admittedly that sort of figure is what you hear from solar energy companies, but it is fairly well known that solar panels, whether PV or thermal, do add value to a house.

Quote
The value that would be added to the resale value of your home is going to be totally dependent on the person buying your home. If you sale it to some one that is into solar power great they will love it but if you try to sale it some one that could care less all they are going to see is the extra maintenance cost associated with the solar power system so they aren't going to want it.

There isn't really any maintenance cost. You fit the panels, wire them to the inverter, which you wire to a meter connected to the electricity grid, and that's it. There are no moving parts and the system should last 30 years at least, accelerated aging tests have shown. You seem to think that solar energy is some kind of minority thing, but surveys have shown that many people think of it as raising the value of a property, especially in the US.

Quote
How much would the maintenance cost be for a system like you are talking about? This is something that no one ever bothers to mention as people like to make it sound like you just install the system and forget it but you can't do that or it won't belong before you find yourself with a really ugly roof ornament that cost you £12k

See above. Nobody bothers to mention it because you do just install the system and forget about it. Well, you don't forget about it really because you see the huge savings on your bills.

For solar energy to be cost effective you would have to be able to take advantage of it any time you need electricity. Now if you just wire in the panels to the inverter and then into the meter you would only get a benefit on sunny days and if you used more electricity then you were producing you would still have to rely on the power company. Sure this would probably reduce your bill a little bit but so would turning off electrical items that aren't being used at the time.

If you really want to make it cost effective you need to have a battery system in place that can store the energy you are making so it will be available at night and on days when the sun isn't brightly shining. These battery systems do require maintenance.

If you did just wire the panels in and not worry about actually storing any electricity they will still require maintenance. You have to keep them clean as the dirtier they get the less sun light actually gets thru to the cells. To get continuous optimal performance out of them they need to be adjusted to different angles at different times of the year due to the position of the sun. Now I am sure you can climb on your roof and clean them yourself and maybe even adjust them but how many people would be willing to do that as I am sure the company that you buy them from will offer to do all this for you for a small fee.

Now don't get me wrong I am not against solar energy and would love to see it used more often but I really hate to hear people talk about how easy and simple it is use but never mention the work that is involved and the other hidden cost that goes along with it.

This bring to mind my next questions.

How many solar panels do you have on your house and how much has it saved you during the year?

Photovoltaics generate more power when the sun is shining strongly than when the sky is cloudy or overcast, sure, but even on dull days they do produce some output. It rains enough here that dust or dirt deposits are not a problem. Where I live they are subsidized by the government. If your PV installation qualifies for the "Feed-in" tariff then you are paid (at the moment) £0.41 per kWH produced. This will be paid even if you use the energy yourself. The cost of importing grid power is around £0.12 per kWH. So that is why a 2 kW installation would save/pay you £900 per year. The feed-in rate is tied to the stadard rate so the return will rise if electricity prices rise. The inverter is connected to the electricity company's cables coming into the house via a bi-directional meter so while you are at work or on vacation all of the power you generate is exported and measured.

My employer's new office building has PVs and also a solar water heating system and the power bills are around 20%-30% of the old building of a similar floor area.

This bring to mind all the people that want to use either hybrid or totally electric cars. Yes if we switch to electric cars we won't be using fossil fuels in them as much but on the other hand you have to stop and think about where all the electricity is going to come from to power these cars?

Hydro electric power isn't sufficient enough as the availability to hydro electric power is no where near what it needs to be.

Most people complain when they see big windmills being put up as they either mess up the view that no one noticed until the windmill was put there or they are a hazard to birds.

Just mention putting a nuclear power plant any where with in 1,000 miles of a city and watch how many people complain or threaten to sue some one.

Solar energy just isn't feasible for a multitude of reason. If it was feasible right now there would already be totally electric cars that run off of nothing but solar enegery

That just leaves us with good ole fossil fuels. So go ahead and have every one drive an electric car that way we can pump all the fossil fuels we were using into the additional power plants that we will need to have.

Green ways of generating power has become lot popular in recent times..Even I have been using solar energy for charging my phone battery..

Hydroelectric power provides almost one-fifth of the world's electricity. China, Canada, Brazil, the United States, and Russia were the five largest producers of hydropower in 2004. One of the world's largest hydro plants is at Three Gorges on China's Yangtze River. The reservoir for this facility started filling in 2003...
...
The biggest hydro plant in the United States is located at the Grand Coulee Dam on the Columbia River in northern Washington. More than 70 percent of the electricity made in Washington State is produced by hydroelectric facilities.

Hydropower is the cheapest way to generate electricity today. That's because once a dam has been built and the equipment installed, the energy source—flowing water—is free. It's a clean fuel source that is renewable yearly by snow and rainfall.
