A is the most important. The advantage of both is that sun comes in the daytime and wind tends to come at night. The best way to solve the variability problem is to either tie into the grid or use batteries to store the electricity you are not using for a later time.
Here are some good tutorials on how to do this and also understand the variability issue:

Yes there are many benefits.
Using the wind to generate energy will permit you to be less dependent on fossil fuels, which are non renewable. So you will actually be helping our environment.
Also, there is the economic factor, you will save hundreds each month in electricity.
If you are going to buy a wind turbine for the home, be prepared, because they are costly. A solution for this would be to build the wind turbine yourself. Here I provide you with a link that has more information about that subject.

If you are talking about the wind turbines that are installed on the roof for ventilation then yes they are very beneficial and not costly.
If you are talking about wind mills that generate electricity that is another story.
It will depend on how much electricity you use and the volume of wind in your area.
The wind mills come in several sizes and prices.
The smaller ones produce 50 amps and hour and requires about a 10 to 15 mph wind for max out put. The cost is around $500. However a battery bank and an inverter is need to convert the DC current from the batteries to AC volts.
Most good solar systems have a wind mill as a back up for cloudy and raining days simply because when it is cloudy it's usually windy.
-------------------------------------------------------------
If you have an average annual wind speed of at least 10mph, have at least an acre of land (varies according to local regulations), and are able to have a tower at least 30' above any obsticle within 300' (that means 30' higher than your house and the trees), and are able to spend at least $10k for installation, then owning a wind turbine may be a viable option. If you answered 'no' to any of those questions, then you'll end up with a very expensive lawn ornament.

I will agree with another answer that "wind turbines" can refer to a wind powered ventilation system: http://www.google.com/products?rls=com.m… My experience is that although useful they are not always a strong enough or constant enough when needed.
They can also refer to an electrical generation system. Physics dictate that the longer the blades on the turbine the more efficient they can be. So while a home wind turbine can provide additional electricity it typically will not give the return on an investment that a 205 meters tall structure will give. Wind speeds must be a relatively constant 20 to 40 mph but too high a speed is likely to damage the windmill. There are several different types of windmills/turbines: http://en.wikipedia.org/wiki/Wind_turbin… Below is a listing of available small wind turbines.
As with any electrical power generation you have to measure your needs against the costs of equipment and its life expectancy. You would also have to measure it against alternatives like photovoltaic cells, parabolic dish and stirling electrical production, ground source heat pump geothermal and stirling electrical production. Geothermal or a grid connection does not need storage but for the other types a hydrogen electrolysis/fuel cell, battery, or capacitor method may be used for storage and the cost of this would have to be factored in.

personal wind turbines are not that expensive
you can go to www.homepower.com
they are as cheap as five grand.

There are lots of companies that make small turbines.
here is a list
http://www.awea.org/smallwind/smsyslst.h…
The problems these face are:
local zoning laws, which usually won't let you put one up.
Integration with utility power, which is only allowed in some areas and with some companies.
Expense, you can pay quite a few thousand dollars, when you include the electronics to integrate the output with the AC mains.
Wind, most locations do not have a steady enough wind to justify the use of a wind turbine.

A windturbine would actually store energy onto a powerful battery, following which a converter would cough up AC 110 or 220
10 months ago
-----------------------------------------------------------
Most solar panels output 12VDC. You then need some sort of charging circuit, to deliver maximum power to charge a battery bank. Then you need an inverter to convert battery power to 110/120/220/240 VAC. Also, if you are on the grid, you'll need an interconnect switch, to protect linemen from shock if they are working nearby.
You can buy turbines and solar panels here: www.canadiantire.ca

You will need to do some homework research.
The rude answer is that it is $$$$$
There are several options
PV photo voltaic
Thermal systems and as you mentioned wind turbines.
Any of those don’t provide civilized energy! You will need to provide for the regulation (uniformity) of the energy. Thais is where the $$$$ comes in.
The reason they usually are 12V is because they are extremely small in power levels compared tu what we are used to in the city.
Hope this answers your question
