Wind Energy

Interested in using wind to develop electricity?  It has been done for years. Wind energy was used by farmers and factories and today, windmills are growing at an alarming rate.

What Has Gone Before?

Windmills were first used to pump water for agriculture and domestic use. As time went on, windmills began to be used for grinding grain and other farm products.  Even up to the middle of the 20^th century, windmills were still used to pump water for livestock and other farming needs.

Today, the windmill has taken on a new look and a new purpose. To use the wind to generate electricity, not just for a single residency, but for an entire town, city or state.

Where Are They Now?

If you take Interstate 10 in California, you can see a large farm of windmills as you approach Los Angeles from the east. Texas has several large farms of windmills and is currently the largest producer of wind energy. Even with this spurt of growth, the United States is still producing only one per cent of its electrical needs from wind energy.

How Big Is It?

Is Wind Energy truly a good energy source?  A windmill, with today’s criteria, is expensive to build.  The tall structure has to be built with the right foundation. You have to get the parts for the turbine and rotor blades. To build, you need the specific construction crew to put it up.

Windmills are getting bigger. The larger the windmill, the wind energy generated goes up exponentially.  In 1981, rotors were ten meters long with a rating of 25 kilowatts.  In 2000, rotors are over seventy feet long with a rating of over 1,600 kilowatts.  Over the last ten years, these windmills are getting bigger and generating more wind energy.

What about Residential Areas?

For homes, one megawatt of wind energy can supply electricity for 225 to 300 homes. With a large windmill, you can supply enough electricity for a small town or factory. With fuel costs going up, windmills supply a nice clean alternative.

Where Are They Being Built?

Large families of windmills are being developed along farmlands, lakes and oceans. Oceans can provide the room to build record setting rotor spans. Flat areas and oceans provide easy access to build the units and supply record amounts of wind energy.

Windmills are not developed in urban areas. The close proximity to tall buildings, along with the roads and freeways, may cause a potential hazard and catastrophe. There are fewer problems to deal with off shore.

How Effective Are They?

Wind energy does not run all the time. There may be days, when it is not windy. Your typical windmill has about a 20% to 30% capacity to develop the wind energy.  If you do get surplus wind power, it can be sold to the local utility companies. These additional funds can help pay some of the capital costs.

What is the Largest System?

The use of wind energy is still being developed. Norway has proposed the world’s largest wind turbine at 533 feet. An energy grid has been proposed for off shore windmill units. Denmark is trying to capitalize on the wind energy off the North Sea. The study includes the efficiency of the wind mill system. 

What About Home Use?

For home use, you need to size the type of windmill you need. Then, check you local codes and the availability of your right of way. Your windmill may be a much smaller unit, but, it may do the job for you.

The Time Is Now!

Wind Energy Systems are growing at an alarming rate. Even though the construction cost is high, the return on electrical energy helps to pay for these costs. Is wind energy right for you? Check out this program!
