Apple Building Solar Farm In North Carolina 172

jfruhlinger writes "Apple's North Carolina data center will, it appears, be turning greener: the company is building a dedicated solar farm to power it. That would be a welcome turnaround for proponents of green energy, as Apple was lured to North Carolina in part by the promise of cheap electricity from coal-fired plants."

Apple Building Solar Farm In North Carolina

  • Yes but it will produce Apple electricity, which will only work with Apple products (such as the "licensed only" chargers for the iPhone). Sure it's possible to adapt the electricity to work with non-Apple products, but then they'll sue you for it.

      • For a datacenter, I imagine they'll be using grid and solar together. What the solar can't supply, the grid does instead. That way you get the solar plant running continually at capacity, but aren't held back by the irregularity of weather.

      Not to be outdone, I heard MicroSoft purchased the land next to Apple's and are planning on building a wind farm. But because the wind doesn't blow there all the time, they've decided to forgo installing generators and instead put in motors so the fan blades move constantly. Do to this cost increase, they are offering sticker placement all over the structures for their preferred OEM's. Also, to get the public excited and to generate buzz, they've decided to use some of the land to hold weekly or monthly concerts. Ticket's go on sale one day before each event.

      Google, in the meantime, has come up with their own solution. They have built their own solar farm, which looks strikingly similar to Apple's, except the materials used are slightly cheaper quality. Anyone visiting the site will tracked throughout the complex (and some have even suggested they were tracked after leaving) and then blasted with offer's to buy cheap Viagra and tons of information regarding solar flares, the solar system, Solaris and the Southern Organization of Live Action Reenactments.

            I agree that borrowing money is probably a poor choice for this stuff, but that's true in general for depreciating assets in general IMO.

            As for "bad investment" -- not so fast. We do not have to convert solar to electric for all applications; there is a real possibility to make solar energy cost-effective when you use it to heat your home.

            But those two don't match up. If 12% of the price is subsidised, then without the subsidy it would cost 14% more. If the break even point is 10 years with the subsidy, then it would be 11.4 years without. For a small-scale home installation, the break even point is closer to seven years without subsidy, for a larger plant it can be anywhere from 2-5 years. Without the subsidy it would be a few months longer, not decades, unless the subsidies are closer to 80% of th

Even if carbon taxes are never enacted, the fossil fuels have greater externalized costs especially related to air quality, radioactivity ( for coal ) and other toxic emissions. Solar (PV, not thermal ) has some from the extraction processes for the raw materials but appear to be much less than coal and are getting better as the tech matures.

Most of these were created up to 100 years ago for creating aluminum, which is no longer being manufactured here, so the power goes to the main grid. And hydro is as clean and 'on demand' as you can get. These aren't the only hydro-dams around here even. NC isn't the worst when it comes to pollution from power generation.

      The flaw there is that (1) photovoltaic cells are actually less efficient at higher temperatures -- an I know how much hotter Texas is than Ontario, and (2) down around Lake Erie you're as far south as (northern) California anyway; a few hundred miles won't make that much difference.

But the environuts don't want that, it might hurt the fish or something.

    Typical high-density data center power consumption: 500w/m^2 for entire building, per floor.

    Max solar flux in NC about 1000w/m^2. But only for 6 hours a day on average. At 12% efficiency, that's 30 watts per square meter average. So the solar farm has to be 16x the size of the data center.

      They'll just stack them 16 layers thick.

    • Did you take into account the effect the solar panels (on the roof) will have on the temperature in the data center?
      If the panels are 15% efficient, the amount of energy reaching the roof decreases by 15% which should lead to a temperature drop.
      If the panels are mounted on frames above the roof, some additional energy will leak away as heat radiating from the panels will heat up the ambient air rather than the roof.
      This won't make much of a dent in the 16x figure, but dropping that to 13x (assuming a 20% lo
