back to article Apple's new data center to be solar powered, 100% green

Apple has announced that it will partner with Nevada's largest power company to build a solar farm to juice its data center in Reno, Nevada. The new photovoltaic power source, to be built in partnership with NV Energy, will pump 43.5 million kilowatt hours per year into the grid that will power the data center, Reuters reports …

    No way will they be able to run it purely on solar.

      I disagree...

      Night not withstanding, they get an awful lot of sunlight over there.

      They wont.

      The electricity generated by the solar arrays gets fed into the power grid and Apple draw their electricity from the power grid. The gimmick is that the solar array is supposed to put more into the grid than Apple take out. That way they can claim they are powered by it.

        Re: Stunt

        And presumably they get to sell to the grid at 5x the price they pay to extract. So their data center gets paid for by the poor people trying to heat their homes

        That's not a gimmick. If their solar systems more than offsets the energy requirenments, that's a viable green energy strategy.

          "That's not a gimmick. If their solar systems more than offsets the energy requirenments, that's a viable green energy strategy."

          Not really. An energy strategy has two components. Firstly, that it generates enough energy in total for the requirement. Tick for Apple. Secondly, that the energy is available when people need it. Fail for Apple. You can generate as much power as you like, using any means you like, but if it isn't available at the right times, you've failed. That's why there is work/investment going into batteries, pumped storage etc. Basically any means of being able to store the energy to cover darkness (solar) or calms (wind) etc.

          So, without the fossil (and other) generating assets in the background, Apple don't have a VIABLE green energy strategy. They could run their datacentres during the day to their hearts content, but would have to switch off overnight!!

            Re: Stunt

            Of course it's viable. As long as only a few % of the nation's (or state's if they don't have a national grid?) energy is produced this way, it is perfectly viable. The problem only comes if a large proportion of energy generation is done this way.

            However, while old-fashioned power stations can't be dialled up/down at the flick of a switch, at least SOME of them must be able to run on a 24-cycle where they ramp up for dark hours. Gas and Nuclear for example,

            And, if more power is needed during the day than at night, stuff like this helps existing power stations run at a more level output.

              And this is precisely the problem. Firstly, Apple is ignoring all that fossil fueled generation plant that makes it's 'strategy' viable when they do their ecological assessment. So, if they want to ignore it for the assessment, their policy isn't viable. If they wish to have a viable policy, they must take it into account when working out the ecological impact and oh dear; suddenly they're nowhere near as green. You can't have it both ways. It either isn't viable or the ecological assessment they're done and their claims are actually wrong.

              However, you have hit the nail on the head around generation capacity on a national scale. Problem is, politicians seem to think that 30% wind generation, or 20% solar (both targets spouted by politicians) can ever be met!! Percentages this high either require some sort of large scale storage, or cannot be met by any generation method that isn't reliable (meaing always sunny of always blowing). So, politicians are spouting off for soundbites without really understanding the underlying issues and requirements.

          Re: Stunt

          No it isn't. If the addition of their solar energy has no effect on the burning of fossil fuels as a result.

          And there are increasing signs that that is exactly what happens with intermittent renewables. All or nearly all the gains are offset by increased losses in balancing the massive and rapid fluctuations in renewable power. This is especially so in the case of solar, which is 'hero to zero' every single day.

          Unless they can offset with another zero carbon technology, like hydro, intermittent renewables do almost nothing to lower fossil fuel burn at all.

    Neon power

    Are we to assume the solar power system will be run using the light from Las Vegas neon signs at night?

    1. jonathanb Silver badge

      Re: Neon power

      There is a solar power station in Spain that works at night. It uses the sun's rays to heat molten salt, and the heat from that is used to power a traditional thermal generator. So if they use one of those, it can be genuinely 100% solar. However, I suspect the capacity of the solar installation is higher than what they need for the data centre, and the surplus is sold off to the grid during the day and bought back at night.

    Wonderful idea this solar stuff. Works nicely during the day and in the summer the days are nice and long. They even have a festival there (Burning Man).

    Geothermal is nice too, until old faithful isn't very. Why not use the geothermal 100% of the time, as it has the ability to power the data center, and just eliminate the expense of the solar plant.

    Oh, wait, there are tax incentives, ask Solyndra!

    So, all us taxpayers will end up paying for a "part time" chunk of power. I can't wait! Winter nights are coming (5-6 months away!).

      Re: Dark?

      Geothermal is a slight inconvenient technology to use... there are probably huge areas where it wouldn't be appropriate at all, and yet more areas where the expense of building such a thing would far outweigh the benefits. If you're in a sunny desert on the other hand, the amount of technical expertise and construction equipment required will be vastly lower.

      I Am Not A Geologist, however. The Nevada site may be a perfect hotspot for all I know, but I rather suspect that a 20MW geothermal installation would have cost a few more pennies than the equivalent solar cells, taxbreaks or no.

    Swings and roundabouts

    The Chocolate Factory is building a solar power station which will connect into Nevada's grid and generate a variable amount of electricity when the sun shines. The total amount generated each year and pumped into the grid will match or exceed what they pull out of the grid 24/7/365 to power their data centre, assuming the design and operation works out. The power station isn't being built to provide electricity just for the data centre.

    Is it really 100% green

    If they have to rely on electricity from other sources overnight?

    Surely the only way this could be 100% green is if they stay off grid and have a shedload of batteries for the overnight?

    Although batteries are hardly green given what it takes to make them.

      Re: Is it really 100% green

      100% offset is a better term perhaps but it's still an achievement. Note that in places like Nevada, they probably need more electricity during the day than at night, since they use A/C in the sun rather than heating in the dark.

      Think past the press release

      Perhaps many of the commentards are like me... we do see some potential upside, but we baulk at the claim it is 100% green because there are still huge downsides. It all depends on how you set the risk-o-meter.

      In this case, there are still huge environmental impacts. Covering hundreds of acres of desert is wiping out part of an ecosystem. It might "only" be a desert and not emotionally charged rain forest, but deserts are far more sensitive to disturbance than rain forests. If Apple chopped down hundreds of acres of rain forest to build their eco-indulgence what would people be saying?

        Ok so they are covering a few hundred acres with a PV array. There are hundreds if not thousands of square miles of this sort of terrain in Nevada. Lots of Nevada is pretty sparsely populated and land is pretty cheap.

        I bought 17,000 acres NW of Ely in 2004 It is empty wilderness for the most part. About 500 acres is tree covered. I've turned it into trust with covenants attached so that no one can build anything more than a log cabin anywhere on it.

        About 400 acres is a derelict silver mine. No one complained when that was in operation now did they? That was far more polluting (IMHO) than either the Google or Apple sites.

          Silver mines can be quite polluting in their immediate environs, but Apples datacentres will be hugely polluting over a much bigger area and to a much larger extent. What about all the pollutants being produced to create all the material used to build the datacentre? What about all the pollutants used to create all the machinery (and operate said) building it? What about all the pollutants created building all the servers etc. inside the datacentre? What about all the pollutants created when swapping the servers etc. every x years?

          I think you'll find the silver mine would have produced far less pollution than Apples datacentre.

Of course, the fact they still require the fossil fueled power stations in the background to cover when their solar farm isn't generating is completely by many!!

      Re: Why the negativity?

      I've got nothing against them using solar power. If they want to be "green" because they think it's the right thing to do and spend only their own massive stockpile of cash then fine. I just think it's disingenuous to say, "Oh look how green we are!" when they are doing it for the tax breaks which I don't think should be subsidized by everyone else.

      Consider both Uncle Sam and Nevada are going to give them tax breaks with Nevada's going on top of the taxes they won't pay on the utility bill. How many of the same people who rail against Apple and Google not paying their "fair share" of taxes think it's fine to get a tax break when doing solar because it's the "right thing to do"? My problem is that taxes is a zero sum game so in order for someone to win (pay less) someone else has to lose (pay more) because we know as sure as the sun is coming up tomorrow that the government isn't going to spend less because Apple got a tax break.

      I'm against it because I don't believe in the government redistributing wealth especially when that flow is toward the rich multinationals like Apple. Don't get me wrong, I know it probably won't be me who has to pay extra because the government has this nasty habit of spending now and paying later by way of deficit spending to pass the buck to the next generation. In short, Apple and their government lackeys aren't picking your pocket they're picking your children's pocket and "won't someone think of the children!"

Sometimes when you hear about a data center going "green" it really means that they've maxed out the regional wiring. Solar cells, code cleanup, hotter servers, and fancy cooling systems aren't so expensive compared to asking the power company to upgrade a few miles of high tension wires.

      Is possible and does work at what cost? This has nothing to do with whether it can be done and be made to work. Everyone knows you could power an entire city on photo voltaic if you wanted to. However, at what cost? All this project proves is it works and is possible if you throw enough subsidies at it. Nothing more. It doesn't prove the technology, simple proves someone is stupid enough to throw a lot of money at Apple to make it financially possible.

  13. Mad Mike

    I think a lot of previous commentators are missing the point here and entering a pointless green/anti-green debate. When any large corporation does this sort of thing, you need to understand why. Bearing in mind Apple are showing themselves to be all about the money (tax avoidance etc.), you can bet this has something to do with reducing costs. Any good publicity you can get out of it at the same time, result.

    Green energy isn't a problem for anyone. I think everyone wants green energy, but the issue is cost. Almost all forms of green energy are hugely more expensive to run than coal and gas. That doesn't mean we shouldn't try and head that way, but that we need to be mindful of costs. In order to drive green energy, just about every country on earth is offering incentives to build green generation. Essentially, they are artificially reducing the cost of the green energy with these subsidies.

    So, why is Apple doing it? They're simply taking advantage of all the incentives and getting the tax breaks, subsidies etc. to lower their bills. Nothing more than that. They're getting good publicity at the same time, which is another result. Who's paying for it? All the other electricity users/taxpayers. They're effectively subsidizing Apple to run this and save themselves money. Additionally, the datacentre actually needs another source of power overnight and this is provided by normal coal/gas etc. generation. Apple should really be paying for part of this, but isn't. Otherwise, their green solar power wouldn't actually be able to power the datacentre!!

    To see how stupid the situation is, you only have to look at solar PV installations in the UK. Any householder who puts solar PV on their roof and got in early (the rate has now dropped) will receive 45p per kWh generated, plus be able to use the electricity themselves. Finally, they can also sell back to the grid at something like 3p a kWh. Interestingly, I know of people who get this 3p on half of what they generate as the power company can't actually work out how much they're exporting!! Given that the kWh price of electricity is somewhere between 10 and 15p (depending on tarrif, standing charge etc.), this is simply printing money!! And who pays for it? All the other electricity users......

    1. MrGoggle

      Every new source if energy needs tax breaks. People are forgetting fossil fuels at one point had tax breaks or government incentives to get these projects off the ground. In countries like the UK coal power stations were owned by the state. Here is an example if one that is private now, but state owned http://en.m.wikipedia.org/wiki/Drax_power_station.

      Most if these state owned power stations were flogged off cheaply so investment can be made and profits generated. As green energy technology improves, whether it be solar or any other source, it would become considerably cheaper than generating energy from fossil fuels in the long run. They are already contributing in reducing carbon emissions. Here us an example if what a green energy company is trying to achieve http://www.ecotricity.co.uk/our-green-energy/energy-independence/our-fuel-mix .

      Yes we do have to pay for the investment through tax breaks or charging users if electricity more to invest back into the infrastructure.

      If you have better alternatives please let us know or should we continue using fossil fuels?

      1. Mad Mike

        "If you have better alternatives please let us know or should we continue using fossil fuels?"

        Mr Goggle.

        I never said we shouldn't do it or we should continue with fossil fuels. I merely said that it's a question of understanding just how large the subsidies are and what biasing effect they're having on the market. Subsidies normally have an effect beyond the limited scope imagined by the people who created them.

        You're quite right in that all energy sources need some help initially, but you have to remember that the subsidy alone for installing solar PV in the UK (private household) was once three times the cost of the electricity provided!! That is huge.

        It's also interesting that you quote Drax as an example. That was built where it was to make use of the local coal. Then, when prices of imported coal changed, it used foreign coal brought in by rail. Now, it is being converted to run on wood pellets brought in from North America. How can that make sense? The argument is that the wood pellets are environment friendly as the trees growing counteract the CO2 generated. However, it fails to take into account all the CO2 produced during transportation, which is ignored!! It also ignores the fact that wood prices are shooting up for building etc. as a direct result of burning wood. As soon as generators started doing this on any appreciable scale, the price of wood for any other purpose started rocketing.

        "As green energy technology improves, whether it be solar or any other source, it would become considerably cheaper than generating energy from fossil fuels in the long run. "

        This has yet to be seen. They've been at it for quite a while now and whilst the costs are dropping, they are still far, far higher than fossil fuels. This is largely because most environmentally friendly means of generation are significantly less efficient. Just look at the efficiency levels of your average solar PV panel. In the long run, I doubt if the costs will ever be less than fossil fuels. However, that doesn't mean we shouldn't be heading in this direction. Interestingly, the technology which most makes sense for the UK and receives the least investment and subsidies is wave/tidal.

        1. itzman

          power engineering is not about generating power

          Its about access to subsidies.

          Coal: Being forced out of business by punitive regulation.

          Nuclear: See above,

          Hydro: Deliberately down-rated in the UK to qualify for higher subsidies.

          Biomass: What to do to get subsidies on an old coal station. Burn wood instead.

          Wind: Hopelessly uneconomic without massive subsidies and by forcing the cost of managing its fluctuations (financial and in terms of emission increases) onto someone else

          Solar: see wind x 5

          Tidal and wave: see solar.

          Gas: uneconomic because its being forced to run in balance mode. So needs subsidies (capacity allowance). Also expensive, but greens like that cos it makes renewables look cheaper, hence anti-fracking which might make gas cheap again.

          There is not one single power source on the UK grid that isn't there ( or no longer there) because of government regulation subsidy and legislation of one sort or another. Its nationalised de facto, in terms of command and control, without actually having to pay to nationalise it.

          Never in the field of human economics has the free market been distorted to such an extent by so few people for so much profit with so little understanding of technology and so little consideration for 'bono publico'

          It is a total utter and complete disgrace.

          And its pathetic of Apple to go along with the essential fraud of renewable energy, simply because the fanbois who buy their massively polluting kit (but that happens in CHINA, so it all OK) have been fooled not only by Apple, but by the Al Gore and gas propaganda machine.

            Re: power engineering is not about generating power

            All this does show that we are not paying the true cost of energy production. Some of the money has to come from the state and some if it from private investment. It is the only way to keep energy prices down for us consumers.

            Renewable energy production is newish if you take out hydro power. Getting efficiencies out if it will take time as technology improves. At the same time we should not be relying on one particular source.

            We need to invest now and think long term. Otherwise we will be in a similar situation to countries like Pakistan where everyone wants cheap affordable energy, yet consumers are unwilling to pay for true cost of energy production. This has resulted in loadshedding and blackouts across the country with lack if investment in the grid and energy production.

          Thanks for your reply.

          Energy production is never cheap or 100% "Green" and we consumers are not paying the true cost if energy.

          It will take time for us to know how much of an impact green energy has made. But, as technology develops with improvements on the grid, energy storage, energy efficient devices, etc, we should see reliance in fossils dwindle.

          Once most if these green projects move from investment phase to "sweating the assets", we should have more stable energy costs and less prone to speculation by investors.

          "As soon as generators started doing this on any appreciable scale, the price of wood for any other purpose started rocketing."

          Rather like when people decided it was a good idea to turn agricultural food into alcohol to burn in vehicles. Whoops, food prices sky rocketed.

          Supply & demand and basic economics is ignored at your peril.

        well since windmills have been around for thousands of years, no more tax breaks for windmills.

        Nuclear on the other hand is relatively new.

      "Apple should really be paying for part of this, but isn't."

      I suspect that Apple will be presented with a bill for electricity usage like every other user on the grid.

      If you meant that Apple should be funding base power generating systems, then, here is a clue, that's what utilities do and they fund it from the punters that buy the energy they produce.

        I'm afraid you're making a basic mistake here. The price you pay for electricity rarely has anything to do with what it actually costs. This is due to the subsidies etc. that bias the market hugely. Some of these subsidies are paid by the electricity markets themselves, whilst some come out of general taxation. It all depends on where you are etc. and the exact regulatory framework there.

        A good example is if you look at companies/tarrifs that claim to be 100% 'green'. Even if this is true (and there's plenty of companies that have sold more 'green' electricity than they've purchased!!), look at the unit price and tell me its real. This sort of green electricity is charged at a little more than 'normal' electricity, but not much. However, in reality, if you remove all the subsidies etc.etc., it actually costs maybe 3-4 times (at least) as much.

        The whole market is so skewed by subsidies and state interference, that nothing is actually what it seems. I don't know what the exact framework is in the US, but in the UK, you could easily be getting a higher unit price in subsides for the electricity you generate than you pay for purchasing off the grid!! This is madness.

        If someone in the UK gets the subsidy rate of 45p a kWh for solar PV generation, you could actually purchase electricity from your supplier (at around 5p a kWh) on the economy 7 tarrif and use that to power a light to shine on your solar PV. As long as the solar PV is at least 15% (roughly) efficient, you would be making money!! And solar PV is anywhere from about 17-27% efficient. Stupid. Really, really stupid.
