Answer:
To start with, there are 165,000 wind turbines producing clean, safe, carbon-free electricity world-wide, with hundreds and thousands in most jurisdictions today. Wind energy is on track to have greater generating capacity than nuclear by 2015 or 2016.
At present, wind energy produces 20% of Holland's needs and is becoming a significant contributor in many other jurisdictions world wide, including Ontario and Texas.
Wind is widely used by societies world-wide.
That said, the primary barrier to wider-spread adoption was greater cost per kilowatt hour for wind energy than for other forms of generation such as nuclear, fossil fuel and hydro. The long-standing subsidies and the lack of full-cost-accounting typically made wind appear uneconomic.
With world-wide investment in wind power through various forms of tax credits and guaranteed rate contracts, the wind industry has increased to achieve significant economies of scale which reduced the actual price substantially. Where there is a level playing field either through matching support as with Ontario's Feed-in-Tariff or the USA's current (but threatened) PTC, or where there is no support for any form of generation such as in Brazil, wind is currently very competitive on a pure price basis.
A:One of the reasons wind energy is not used more is that political and other interest groups have lobbied against its use.Mainly because there are several other options.
Wind energy is comparatively clean energy, but requires a large capital investment to build turbines and transmission lines. It is most effective where there is a regular and energetic airflow, such as seashores and valleys. Even with massive development, wind energy alone could not provide the current energy needs of most areas of the country, or of the world.
Several things. Not all places have the type of winds needed, property right of ways and ownership, money and investors, the belief by some there isn't a need, politics, and energy companies trying to stop progress.
It does use wind power. There are areas where you can see what we call Wind Farms - rows and rows of windmills.
But we don't get much energy from wind. Partly it's because we don't have many available areas with sufficient wind to make it economic. Partly it's because we haven't got round to doing it yet.
all nonrenewable fuels can be traced back to the sun as a primary energy source
The Sun.
the ultimate source of energy for all living organisms is the sun
Carbohydrates
Electricity , as a secondary source of energy, is easy to transport and easy to be converted at end energy use point to energy the form needed (as in lighting, heating, industry, transportation, etc.). Electricity by itself as secondary energy source is environmentally clean secondary energy source. Pollution caused by its production depends on the type of the used primary source (coal, oil, gas, nuclear energy, wind, etc.) However, electricity is usually produced in thermal power plants at efficiency less than 50%. So, it is expensive high grade secondary energy source.
Hydro electric ,thermal and nuclear energy
Over half of the electric power generated in the U.S. is being generated by coal fired electric power plants.
primary
Carbohydrates are the body's primary and immediate source of energy.

The term clean source of energy refers to only primary energy sources as wind or solar energy. Electricity, by definition, is not a primary energy source. It is a secondary energy source that is could be produced by a clean energy source as wind or any renewable primary energy source or produced by fossil energy source as oil, natural gas, or coal.
The Sun is the primary source of all energy on Earth.
Carbohydrates are the primary energy source for herbivores (cows, horses, etc.). Proteins are the primary energy source for carnivores (dogs, cats, etc.).
The sun is the initial (primary) energy source for life. Ingestion and digestion of a food source is an animal's primary source of energy.
The primary is the sun
Glucose is considered a simple sugar. It is a primary energy source for the brain.
