A wind farm is a collection of wind turbines in the same location and used for the generation of wind power electricity.
Wind farms present an economy of scale along with an efficiency factor that enable them to produce electricity in the price range of conventional energy sources, and hence compete with conventional grid power.
Note: "Conventional Grid Power" is currently produced by burning coal.

Note: Coal costs a lot of something to mine, ship, and consume in the process of generating electricity. Wind is farmed into electricity with windmills. How long does wind last?
How long does a wind turbine last?

Bypassing Peak Energy (http://alfin2100.blogspot.com/2006/06/silicon-free-solar-cells-bypassing.html) - Daystar Technologies' unique metal foil design is not vulnerable to silicon shortages. At a price approaching grid, production of this thin film design is being ramped up to 20 MW per year. (Al Fin BlogSpot; June 18, 2006)
Note: Farming Sunlight? When does sunlight run out? How many years will a Solar Cell continue to turn sunlight into electricity?

" Our Phase II system will cost (us)
- 18 cents / Watt for materials
- 29 cents / Watt installed in a large solar farm
Compared with $5 / W for conventional solar installations."
Note: That appears to be an 'installation' cost. If the duration of the power output is not factored into cost, then, the cost/benefit analysis is incomplete.
Example:
Suppose a person spent 30,000 units (dollars, euros, Yen, Yaun, ounces of gold, ounces of silver, etc.) to install a generator for his home. If the generator lasts 100 years, then, his children's children continue to get POWER after the 'loan' or the investment (including INTEREST) is long ago PAID IN FULL.

International Automated Systems, Inc. (IAUS)
IAUS has brought forward several technologies, including a solar technology. In addition to their fresnel lens and turbine solar technology, they are presently developing a waste-to-energy technology line.
In their solar array, fresnel lenses focus sun's rays to heat water to run a patented high-efficiency turbine. A utility-scale application is in process of being built in Nevada which will compete with grid electricity.
