Apple Building Solar Farm In North Carolina 172

Posted by samzenpus from the working-on-sunshine dept.
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."

      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.

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.
