Apple seeks to build a solar farm to power data center in Reno, Nevada

Apple is planning on utilizing a new type of technology for the solar array. The system will use panels in conjunction with mirrors that will concentrate the sun’s energy buy up to seven times into the panels, resulting in greater power generation. The final set up will generate between 18 and 20 mega-watts of power.
"All of Apple’s data centers use 100 percent renewable energy, and we are on track to meet that goal in our new Reno data center using the latest in high-efficiency concentrating solar panels. This project will not only supply renewable energy for our data center but also provide clean energy to the local power grid, through a first-of-its-kind partnership with NV Energy. When completed, the 137 acre solar array will generate approximately 43.5 million kilowatt hours of clean energy, equivalent to taking 6,400 passenger vehicles off the road per year."
