the carbon emission of the United State had grown 0.8% year by year for the last quarter century. As a percent this might not seem a lot. However this would total to millions of tons of carbon discharges and it is due to this reason that American wind energy was put in with the hope of reducing pollution caused by power generation in the country.

In the year of 2008, the total of wind energy in total exceeded 8,500 MW in the United States. Therefore american wind energy has gone from strength to strength. However most green radicals claim that this rate of development in american wind energy is dissatisfactory and lobbies for greater use of sustainable green energy.

In the road to gain wind energy, the government had to face many obstacles. First of course is the matter affecting the expenses. Establishing wind energy is relatively expensive. Therefore american wind energy tends to be quite expensive and this has been one of the greatest obstructions. Another problem is caused by the birds when they directly fly towards the rotor blades. Transporting the needed equipment has also been an matter as the suitable areas tends to be quite remote. The equipment also takes up a significant area. If american wind energy is to flourish further solutions would have to be found to these problems. At least for some of these problems, technological developments and advancements can offer answers.

One of the added advantages of american wind energy is that it has lead to gain in employment chances in rural remote areas where employment is hard to find. Farmers can gain their incomes leasing the land and crops could be grown around the turbine, up to its very base. Therefore american wind energy may have been a god sent opportunity to develop and transfer rural America.

Use of wind energy does not necessarily have to be at the national or state level. You can now enjoy the gains of american wind energy through the use of a small wind machine which could provide adequate electricity to meet the needs of a house. Since use of wind energy has increased within the country many firms are now involved in the industry. The potential for american wind energy does look quite good.

Some scientists have expressed that wind power is far more beneficial to that of the solar power as its still available even after the sun sets. Wind power is a free energy source and it eleminates the use of any material for generating energy. However wind power energy has its disfavours, there s a high price needed in setting up these wind turbines adding onto that the need for the right placement to be set up needs to be considered. Wind energy is not that simple when it comes to installing and can be quite complex.

Most of the systems require maintenance on a regular basis and as well as the replacing particular parts. These parts such as battery packs are quite expensive. One of the disfavours of wind energy is that depending on the unpredictable nature of making energy. The potential of wind energy relies on the speed of wind, if the wind slows down the entire system will not work towards its capacity. Only particular areas in the United States will there be continuous wind energy available. In terms of the other areas, it s not viable to switch to wind energy even if it s cost effective. Backup energy resources needs to be available if the wind is not steady.

The other disadvantage of wind energy is that it s often located in remote areas; this increases the costs of transporting the energy that s produced in these farms. Wind energy needs to be received by a large number of people if it were to be useful. Adding onto the transporting this energy may not be that simple. Wind resource development may be a contest for other uses of land. Instead of apportioning the land for wind energy it can be used for generate something more critical to the country.

Although wind energy plants are less hazardous to the surrounding environment when compared to other plants, they contribute to a particular level of pollution. The noise that s produced by the rotor blades can create aesthetic visible impacts and sometimes birds get killed by flying into these rotor blades. Wind farms take up a lot of space in order to be setup, in nations where space is limited this is not favorable. For a wind energy generator to start work, it requires the assistance of an external power source. These are the few disfavours that wind energy which could impact its use.

Simple Instructions To Build A Windmill For The Handyman In You

Posted on timeAugust 22nd, 2009 by userGrace     flagComments Off


With oil prices moving higher and higher, power costs tend to follow the same trend. Given that our daily life relies very much on the consumption of electricity, getting your power from alternative sources is an attractive option.

The sun, water, and even wind are viable sources of power. What’s more, they are renewable sources of energy as they are constantly present in our environment. More and more people now want to set-up their own windmill at their homes. With the many instructions to build a windmill available out there, it is up to you to find the one that is easy to comprehend.

Here are some helpful instructions to build a windmill:

Basically, there are several distinct types of windmills, based on the direction their blades spin:

1. The Horizontal upwind, where the shaft stands horizontally and the wind hits the blade before the tower;

2. The Horizontal downwind where the wind hits the tower prior to the blade; and

3. The Vertical Axis, mounted on short towers and its blades are pointing upwards.

Essentially, a windmill has four componants that must be given extra attention:

- base
- tower
- blades
- nacelle

In building this structure, the main objective is to maximize the conversion of the wind’s power into electricity. Therefore, it should be high enough to take advantage of the wind’s action in obstructed terrains – a customary tower usually stands at 5 feet.

The base must be strong and heavy compared with other parts, to assure a sturdy structure because it is the main foundation. It is advisable to use materials like sandbags or concrete, and in the case of a five-foot windmill, the base must be at least 18 inches square thick and 20 pounds heavy.

The tower supports the blade in gathering wind energy. There are many approaches when building it. You can either use guyed lattice or steel and pipe tubings or erect them using a jin pole or crane.

The nacelle connects the blade to the tower and contains copper wires and magnets that run the blade and help change the wind’s energy to electricity.

The blade is the propeller used to capture the wind’s energy, so it is necessary that the blades are able to catch the flow of the wind easily, rotating with the least potential resistance.

Materials to be used for these parts must be lightweight, so you can carve them from plastic or PVC pipes. Note that in strong winds and storms, the blades can become a danger if separated from the structure, so be sure to lock in the blades tightly, keeping safety precautions in mind.

Considering that a simple windmill could cost at least $40,000, building one for personal use can be quite expensive, but utilizing what is around you can help you save some expenses.

It is thus recommended to recycle parts in order to reduce your expenses. Following these simple instructions to build a windmill will enable you to build one from scratch.

Windmills are just the beginning. To learn more about solar and wind power, go to Solar and Wind Power For Residential Homes or if you are looking for a simple way of building your own residential wind generator, see our Energy4Green Review.

How Do Windmills Work What You Need To Know

Posted on timeJune 20th, 2009 by userGrace     flagComments Off


Windmills were previously used in early times to pump water out of the ground to irrigate systems and to grind wheat. Through progressive technology, they soon found other useful purposes for these windmills. With a little human ingenuity, they have been made to produce electricity. But how do windmills works?

Wind power is a renewable kind of energy and it is a powerful source as well. It is considered as one of the most sensible and ideal sources because it produces zero emission and it is abundantly free. The best thing about the structure is that it can reduce the energy bill of any home by 50 to 80 percent.

Basically this structure consists of 2 to 3 blades that are linked to a shaft. These blades are used to collect the wind energy that flows over them. The shaft meanwhile is wired into a generator, which then is connected to a battery. The generator is also referred to as the heart of such a mechanism, as it is the one that converts the energy collected.

Upon gathering and converting, a battery is needed for storing all the collected energy, which then can be connected or linked into a home’s electrical system.

How Do Windmills Work – The progression:

- First of all, it reduces the speed of the wind using the blades, which work in the same way as airplane’s propellers.

- When the wind flows over the blades, these blades collect kinetic energy.

- Then the blades, which are connected to a drive shaft, revolve slowly and send a lot of the turning force into the gearbox.

- The gearbox then modifies this turning force, and instead of revolving slowly with a lot of force in every revolution, it goes faster with less force in every revolution.

- At that moment, the generator, which is linked to the gearbox, creates electricity through the many magnets and copper wires inside of it.

An important factor that plays a vital role on the way this machine works is the size of the structure itself, as the amount of electricity produced depends upon it. The bigger it is, the more powerfully it can drive the shaft, which means the greater electricity it can produce.

You might also notice that some windmills are situated on top of valleys and mountains. This is because the blend of hot and cold air can create moving air. Sometimes they are placed near bodies of water, because this also generates wind due to the change in temperature brought about by the sea and the sun.

One important fact on how windmills work is that a single turbine can produce 100 megawatts of electricity. Imagine then how much electricity a wind farm with large turbines grouped together can produce to provide bulk power to an electrical grid.

Can A Residential Wind Generator Work In Your Neighborhood?

Posted on timeJune 19th, 2009 by userGrace     flagComments Off


The residential wind generator idea is gaining popularity worldwide, as living in this day and age has become quite expensive, with even the basic necessities becoming too costly to acquire. One of these necessities is our need for electricity. With fuel prices going up, everyone is looking for ways to economize their expenses to be able to afford electric bills.

Many are choosing to either buy or build their own wind turbines, but are having some doubts and concerns. So here are some pieces of information that may be able to help satisfy the information needs of most people when thinking of getting a wind turbine.

- This device is usually installed above a high tower where it can gather kinetic energy from the wind’s motion and convert it into electricity through a generator.

- Normally, a home that has installed a wind turbine is constantly served by the turbine itself and by their local utility. If the wind speed doesn’t fall into the cut-in rate, which is 7-10 mph, electricity would then be supplied by the electric utility.

- The basic rule of wind turbines is that “as the wind increases, output for the turbine also increases while the current supplied by the utility is lowered.

- If there is excess electricity collected, it is automatically sold back to the utility, because residential wind generators normally have no battery packs.

- Small wind turbines could in fact lower power bills by 50 to 80 percent. The amount of money it can save depends upon the consumption of electricity, the average wind speed on site, and other factors.

- A residential wind generator is rather large and may not be suitable for urban or small-lot housings, as wind systems are sensitive to the speed of the wind within the area it is situated.

- Wind turbines are pollution-free, and a small type can actually offset nearly 1.2 tons of air pollutants and tons of greenhouse gases that cause global warming.

- A typical wind turbine system makes less noise than the average washing machine, and it also does not interfere with the television’s reception in spite of what others think, as their blades are made from wood, plastic, and fiberglass.

- Upon installing the turbine, there is no need to rewire the appliances in a home since wind turbines are retrofitted to any home without altering the wiring or appliances.

- With regard to towers, tall towers are necessary to stop any hindrances that could prevent it from freely gathering wind energy. The most economical type of tower would be the guyed lattice tower, while a hinged tower can be easier to install and maintain. Most small turbines are not high maintenance, since they have very few moving parts, and can operate and last up to 20 years.

A residential wind generator can be a good investment, although the return through your power bill savings would only be visible after 6 months to 15 years. Another advantage is that a well-working turbine would increase in property value.

Windmills are just the beginning. To learn more about wind and solar energy, read Advantages and Disadvantages of Wind Energy or if you are thinking of building your own residential wind generator, see our Earth4Energy Review.
