Rooftop Wind Turbines: Throw Caution to the Wind
Rooftop wind turbines offer a relatively inexpensive way to participate in the rush to renewable energy. The principle allure is low installation cost. Typically, tower installations for larger turbines add 50-80% to the cost of the system. With a rooftop turbine, an $800 tower is replaced by a $39 roof mounted tripod, or a length of pipe attached to the side of the house.
According to Ron Stimmel of the American Wind Energy Association, "…rooftop turbines still account for only 1 percent or so of the 10,000 small wind turbines that are sold each year in the country." For this reason, few performance statistics are available from actual owners.
It's possible, however, to get an idea of the estimated power output of a rooftop turbine from the manufacturer's website. For example, the Energy Performance chart for Southwest Wind power's 200W Air Breeze predicts 20-30 kWh (kilowatt hours) per month from 10-12 mph winds occurring 6 hours per day.
To put this in perspective, 30 kWh is less than 5% of the power consumed each month by the average household. Overall, the payback from a single, roof mounted turbine in tangible financial terms leaves a lot to be desired; especially in light of the fact that unlike solar, there is no Federal tax credit for residential wind power.
But anyone thinking about installing a rooftop turbine(s) is probably aware of this already. The rooftop wind enthusiast is not motivated by financial relief, but rather the intangible rewards of pride of ownership, walking the walk, or simple satisfaction as a hobbyist.
Motivation aside, it doesn't make sense on any level to proceed with a wind powered project unless the three following requirements are met:
1. Higher than average cost per kWh. The more you pay per kWh for electricity, the more economical wind power becomes. A rule of thumb in the wind turbine industry states a residential wind powered system shouldn't be considered unless you pay $0.10 or more per kWh for electricity.
The easiest way to determine your cost per kWh is divide the current monthly balance on your electric bill by kWh usage (also plainly stated on your bill).
2. Building codes. Visit your building department to find out if there are any zoning restrictions for roof top turbines. Don't build your rooftop system first and ask questions later - only to be told it violates zoning laws and must come down.
3. Minimum wind speed. Wind speed of 7 mph, or 3 m/s (meters per second) is the start up speed for just about every wind turbine. However, in order to get any "juice" out of the turbine, minimum wind speeds of 10-12 mph for 6 hours per day are necessary.
Although wind speed charts for the United States and Canada are available to help site larger turbines, they're of little use for rooftop systems because the data is collected at a minimum altitude of 30 meters (98.4 feet).
However, you can get a good idea of the wind speed at proposed turbine locations by purchasing an anemometer (wind speed meter) for around $150. The kit comes with a rooftop sensor, 60' of cable and mounting hardware for the read out display. These are not data logging meters, so you'll have to keep notes on your observations.
If you're really serious about wind speed data collection, you can purchase a data logging anemometer kit with tracking software for $400.
Depending on where you live, wind speeds generally fluctuate with the seasons. Readings taken during the hot summer months of July and August, when you're begging for a breeze, are not usually a reliable indicator of average yearly wind speed.
Also, rooftop turbines located at the edge of a long flat roof experience much more wind than those located on roof peaks.
If, after a month or two of collecting data you determine there just isn't enough wind for a rooftop wind turbine, you can always resell the anemometer and turn your attention towards solar.

soil moisture is measured by?
(A) Psychrometer (B) Lux-meter (c) Anemometer (D) Tensiometer
Well your answer is TENSIOMETER.
A tensiometer is a moisture measurement tool
that measures how hard the plant is working to
extract water from the soil.
And the below is for your information, if necessary read it or ignore.
An anemometer is a device for measuring the wind speed, and is one instrument used in a weather station. The term is derived from the Greek word anemos, meaning wind. The first known description of an anemometer was given by Leon Battista Alberti in around 1450
The lux (symbol: lx) is the SI unit of luminance and luminous remittance. It is used in photometry as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception. In English, "lux" is used in both singular and plural.
A psychrometer is an instrument commonly used in laboratories to measure relative humidity. It is also referred to as a wet- and dry-bulb thermometer.
