NEW YORK (

TheStreet

) -- The hottest trend in manufacturing these days may be the solar farm.

A factory at a greenfield site with ample land around it contracts with a solar-panel maker and a utility to erect a large number of panels near the site, which help power the factory and keep everything green. Lots of companies now have them, even

notes Energy.Gov.

Putting a solar farm next to a factory also means that the power doesn't have far to go. Having a power source hundreds of miles away means energy is lost during transmission, because power lines aren't perfect conductors. Check the inverter box that sits between your laptop and the wall sometime. That warmth you feel is energy being lost in the form of heat.

Solar farms are quickly becoming routine projects. As of last September, California alone had more than a dozen large solar projects

underway.

Apple

is now funding construction of its second such facility, which will power a new data center outside Reno, Nev.

Apple is contracting directly with the local utility,

NV Energy

(NVE)

, to place panels on 137 acres, according to a story first reported by

Katie Fehrenbacher at GigaOm.

NV Energy is in the process of being acquired by

Mid-American Energy

, which in turn is owned by

.

Mid-American, in turn, was among the utilities which pioneered in this area, buying turnkey plants built by

First Solar

and

SunPower

(SPWR) - Get Report

, then using its financial strength to sell notes against them through its

Solar Star Funding

unit,

according to a Business Wire press release.

Apple did a similar deal for its data center in Maiden, N.C., with SunPower providing panels backed by fuel cells from

Duke Energy

(DUK) - Get Report

and privately held

Bloom Energy

doing the heavy lifting. In Nevada, NV Energy plans to combine photovoltaics with concentrated solar-power mirrors, meaning the facility will supply energy at night as well as during the day. Until the array is complete, Apple will power its center with geothermal power from the local electrical grid.

Google

(GOOG) - Get Report

says it has put $1 billion

into solar and wind projects that will generate 2 Gwatts watts of energy. The Apple Nevada project is rated at 20 Mwatts.

Solar farms aren't always wildly popular. Environmentalists sued to stop one in California recently,

KQED reported recently

, citing risks to endangered species. Companies such as First Solar that install many solar farms now track risks to species on their Web sites. (

Here's First Solar's.

All of which means that the biggest story in Apple's solar-farm announcement is that it's not a big story.
