Windspire is a low-cost, easy-to-install wind power appliance that provides a safe and attractive method for harnessing power from the wind. At only 30 feet tall and 2 feet wide, Windspire is safe for birds and people, and is distinguished by its sleek propeller-free design, silent operation, rugged construction, simple installation and affordable pricing. Designed for operation where we live and work, it sells for $3,995.00 and comes complete with the inverter, poles, and an installation kit.
Power from Advanced Technology - Mariah Power’s patented technology includes a rotor, generator, and inverter designed as a complete system to optimize the conversion of wind energy into electricity. The 1kW (1 kilowatt, or 1,000 watts) Windspire will produce approximately 1900* kilowatt hours per year in 12 mile per hour average winds. The Windspire also includes an internal wireless modem that can continuously transmit power production information directly to your computer so you can check your power production at any time.
What does that mean?
How about another search to see the average montly rate of electric power consumption.
Power is measured as kilowatts.

Energy, Power, and Force are all based upon mass, displacment (movement from one place to another place), and time. The standard unit of time is one second. Energy, Power, and Force can be converted when TIME is understood.
This time I'm going to focus on one MONTH as the time factor.
Keep in mind: How much does it cost and how much does it produce.
So...google for Average Electric Power Consumption
How about this one:
http://hypertextbook.com/facts/2003/BoiLu.shtml
"A kilowatt-hour is the electrical energy consumed in one hour at the constant rate of one kilowatt. The average household in the United States uses about 8,900 kilowatt-hours of electricity each year."
Power is defined as the rate at which work is done or energy is consumed. The formula for average power is acquired by dividing work by the time needed to perform work: P = W/t. Power has units of newton-meters per second or joules per second or watts.
The electric power produced for our residences come from power plants through a power distribution grid. The electric power derives from a power site within the power plant. The power site of a power system consists of a central mover like a turbine that is then pushed by water or steam to run a system of generators.
The amount of power that a household consumes depends on how many appliances there areand the amount of time they are in use. Some appliances or machineries take a lot of energy to operate, so it will result in more use of power.
Those are a lot of words and life it short.
Numbers:
$3,995.00
That is the Price (the cost to produce the generator is not the same thing as the price) and that is the cost to you the consumer.
Output for $3,995.00 is:
1900* kilowatt hours per year (stick with YEAR for now instead of MONTH)
4 thousand buys 1900 kilowatt hours
Average demand or rate of consumption is:
8,900 kilowatt-hours per year.
You can do whatever math you want while I am going to calculate how much it would cost to more than double the production of electricity and sell the excess electricity.
Producing more than double the average home rate of consumption:
20,000 kilowatt-hours per year.
I need the number of wind generators needed to produce 20,000 kilowatt-hours per year:
20,000 divided by 2000 (rounding up) = 10
See how easy this is?
It cost $4,000 for each wind generator so I spend $40,000 (4 times 10) to produce twice (rounding) my annual consumption of electricity.
We pay about 100 dollars a month average and electricity is about .13 cents per kilowatt-hour.
This is, of course, very rough estimating; however - I turn my house into a 50 dollar a month electricity farm for the cost of $40,000 dollars.
I use the 50 dollar a month income figure because I sell my excess electricity at half price to my neighbor (the electric company does not buy electricity from individual home producers currently).
50 dollars divides into 40,000 to find how much time it takes to pay off my investment. 800 months or 67 years.
You can look at this another way. I save my own 100 dollars per month that would be sent to the electric company and suppose I soak my neighbor and charge him the full 100 dollars?
200 dollars divides into 40,000 to find how much time it takes to pay off my investment.
That is 200.
200 months is 17 years.
That is another way of looking at this power independence stuff.
Instead of selling the excess production to your neighbor what happens if you buy an electric car instead and will the car use up all of your excess electricity and/or will you no longer have a gasoline bill and no longer have an electric bill and pay off your loan (to yourself) after 17 years?
In my view the market has yet to realize a need to produce more because more is better.
Rather than buy 10 low output producers there is economy in producing more with less. Does that make sense. There is also a need to diversify and split the investment between Solar Panels and Wind Generators.
