With the burden on the earth’s natural resources becoming more onerous, alternative electric energy is becoming less of an option and more of a necessity. The toll on the environment also requires us to explore realistic solutions to preserve dwindling resources.

Since the industrial revolution, we have placed heavy demand on non renewable resources such as coal, oil, and gas. In some countries deforestation is compounded by people who still use wood for charcoal. This trend cannot continue and massive investment into alternative electric energy is imperative.

Proponents of alternative electric energy tell us that we can preserve the world’s resources by adopting renewable energy systems. They say that instead of continuing to rely on non renewable fuels we should employ new sustainable technology. Such technology works by generating electricity from abundant sources that can be harnessed quite easily. Most alternative electric energy systems are simple to understand and utilize.

There is nothing new about using renewable sources for energy. Many alternative electric energy systems are simply an updated version of old fashioned technology. Sources of energy can be generated using the power of the wind, sun or water.

The old windmills that were used by farmers to grind wheat can still be seen as historic artifacts gracing many European landscapes. Modern alternative electric energy windmills now turn to produce electricity instead of mill grain. The basic principles behind the old and the new windmills is essentially the same. Both trap the wind’s energy in great vanes which turn a shaft. Old mill shafts were connected to millstones while their modern counterparts spin turbines that produce electricity.

Hydro electric power is an alternative electric energy system that is not new in concept. Hydro power stations are the preferred choice in some areas for providing electricity to a large population. Their main benefits are that they are not expensive to run and they do not pollute the environment. This type of alternative electric energy system is often worked by the force of water in a dam which passes over turbine blades to generate electricity. Prototypes of the modern hydro turbine were huge wheels that turned millstones in the past.

The most popular alternative electricity system for homes, schools and businesses is solar power. The technology used is the most groundbreaking because it harnesses the sun’s energy with tiny components called photo voltaic cells. These cells convert the energy into electricity which is able to charge batteries for consumers to make use of as needed. Solar energy is a slightly more complex technology than other alternative electricity systems but it also the most adaptable.

The need for alternative fuel sources has been a topic of hot debate and dire concern for decades. It is only as we reach points of energy catastrophe and economic peril that the issue is taken seriously. Researchers and scientists in many countries have been planning for this time with research and practice in wind farms. The United States, the European Union and the United Kingdom have all begun investing in wind technology.

Wind farms exist in rural areas across America. These are on shore wind farms and have been in use since the 1970’s. Offshore wind farms mimic the same pattern of onshore wind farms on the ocean floor close to the coast. The limiting factor in offshore wind farms is the topography of the ocean floor. Shallow waters are required for financially feasible offshore wind farm. Onshore wind farms might be a better solution for areas with large plains and flat lands. Wind farms have stood in California’s Central Valley for nearly 3 decades. California uses the power generated by its central valley wind farms to add to the state’s supply of fossil fuels.

The United Kingdom has taken steps to map a future powered by off shore wind farms. The shelved sea floor off the coast of Great Britain is ideal for the placement of turbines. Massive off shore wind farms have not been built in the U.S. yet. However, the topography of the ocean floor surrounding the United States might be a limiting factor. Gigantic underwater canyons and steep drops will be keeping wind farms off of the U.S. pacific coast.

Off shore wind power generation is more consistent than onshore wind turbines because winds at sea are more consistent, stronger, and the turbines can be much larger. However, offshore wind generated power is only one piece of the wind power puzzle. Benefits of onshore power farms are sources of income for landowners, tax benefits, and job creation.

Wind power has the capacity to produce more than 100 billion kilowatt hours worldwide yearly. The main hindrance to this wind generated power technologies lies in the cost of the turbines. The rate at which the turbines pay themselves off however is faster than any other power producing mechanism.

Denmark has led the way in wind generated power and encouraged participation from countries like the U.S. and the U.K. There is great hope that wind generated power can create energy independence for developing nations Like Africa and Nicaragua.

Funding for wind generating power projects come from a number of sources including, government, research groups, foundations and power companies. The outlook for wind farms is good in the United States. In a time of economic crisis it is estimated that government sponsored initiatives in alternative energy will produce jobs at a rate of 4.8 jobs for every mega watt of power installed.

The amount of money that wind power can save you depends on many factors. It can be significantly a large amount of money for you if you have a good sized system and what the system is for. Many of the factors that determine the amount of money you can save includes the amount of wind you have, the type of system, the amount of energy you use, and much more.

If you are wanting to lower your monthly energy bill, as most of us do, then wind powered systems are definitely a smart choice. Wind turbines rely solely on the wind and they create and store the energy that is generated from the wind. Whatever the amount of energy you use, generally speaking, wind turbines will provide around twenty percent of that amount.

Your generator will be full most of the time if you live in area that experiences a lot of wind. However, if you live in an area where the wind is minimal, this will mean that the generator will not be able to store much electricity.

What you will need is fast and strong wind and this is what will cause your system to operate to its maximum capacity. If all you get is a light breeze most of the time then you will not be able to enjoy much of a benefit.

The type of system you have for wind energy makes a big difference on the amount of money you can save when you have a wind electricity system. A home system can be an excellent supplement and even provide electricity that may give you the majority of your electricity while you are at home.

Some people choose to have a solar system as well as a wind powered system and, because they produce an abundance of electricity, they are usually pleasantly surprised when they are credited on their electricity bill. The electricity company will credit you or even give you cash back if you have more energy than what you have used through their services. Your bill can decrease by between twenty and seventy-five percent if you have both a solar system and a wind powered system.

Some watches use wind powered systems. They are called Kinetic watches and rely on the wind that is generated from the movement of your arm. They contain a very small generator and the amount of savings are minimal. Although you will not have to buy batteries and will therefore save on that expense it will not add up to more than a few dollars over a few years. On the other hand, you have the advantage of knowing that you are not negatively impacting on the environment because you are not discarding batteries every so often.

The amount of energy you use is a big factor when you have a wind powered system and want to save a lot of money. If you run big appliances on a constant basis then the savings may not be very big. If you are very energy conscious and you pay attention to the appliances that you have in your home that consume energy then you can save more money. The goal for most homeowners is to use wind power entirely rather than pay an electricity bill at all.

Back in the day if you thought about a home wind turbine, what would have come to mind is a large tower with enormous white blades spinning rather slowly. But, with the development in technology and the need for more and more people to become energy efficient, small residential wind turbines can now be erected at home. Even better news for green enthusiasts is the ability to make their home wind turbine, without spending thousands of dollars on contractors.

So, how does a home wind turbine make power?

A home wind turbine produces power by moving a small turbine. This turbine is attached to a hub, where 3 or 5 blades are fixed, which in turn is placed at the top a tall tower. To keep the blades spinning, a guidance system or tail is attached to the hub, to keep it facing the wind.

If you do not know what a turbine/motor is or how it works, let me explain. Copper coils spin past magnets, and create an electromagnetic charge. This charge is then sent through wires to the batteries where it is stored. To use that charge in your home it needs to be passed through an inverter that changes the current from direct to alternating current. The reason wind power has become more popular on a small scale, is because of the improvement and efficiency in the design of the turbine.

The tower is usually quite tall to help the blades catch as much wind as possible. But in open, windy areas, such as near the ocean, the tower can be a little lower.

With more money being put into research, the blades have changed drastically over the years. The rotors generally have 3 instead in of 5 blades now, since the blades have become lighter, stronger, and able to spin in very light breezes. The blades also come an assortment of diameters, according to the average wind speeds and energy needs.

Up until now I have been talking about your average horizontal axis home wind turbine. But there is also another design taking off. It is a wind turbine that spins on the vertical axis. Also know as a VAWT (vertical axis wind turbine), this generator’s blades resemble some type of water-wheel on its side. The problem with the VAWT is that it spins rather close to the ground, making it unable to catch the stronger, higher up winds, so it is not a good option for residential home-owners. Also when erected in open areas, the blades are large and spin so fast birds do not see them and fly straight into them - which is not very eco-friendly.

What you need to know before you buy a home wind turbine:

How big is the property?

Wind turbines generally operate better in large areas that cover an acre. This is because wind flow is not deflected by any nearby buildings.

How windy is it where you live?

The recommended wind speed should be at least eleven miles per hour, but if that isn’t the case then you may have to use a taller tower and larger blades to catch higher altitude winds.

What else can I use the wind turbine for?

The more uses you can think of for your wind power, the more attractive it will be to get one. Windmills have been used for centuries to pump water through irrigation systems, and farmers still use them today.

Do you rely on an uninterrupted power supply?

This is why so many people want to get a small wind turbine in the first place - to keep the house powered during blackouts, and prevent economic losses. Although the wind turbine may not power the house all the time, it’s stored power can be used in emergencies, when the utilities are just not enough.

Taking the above points into consideration will help you determine how much power you require, the length of tower needed, the diameter of the blades, and the benefits and costs of using a home wind turbine.

The nice thing about technological developments is that the motor are becoming small and lighter. This make it possible to install to a few smaller wind turbine right on the roof, and make a similar amount of power to one larger home wind turbine.

Though expert installations can be anything up to $100,000, it is possible to learn how to make your own home wind turbine for a small fraction of the cost. What’s more is America and other countries offer tax rebates to energy efficient homeowners, so not only will you save on utility bills, but also pay less tax.

One of the main contributors to the level of carbon dioxide in the environment is the production of energy. We pretty much take electricity for granted in developed/developing countries. We will casually flick a switch and on go the lights, the television and the microwave. But have you ever wondered where your energy is coming from?  If you haven’t, then it might surprise you that most of our current energy needs are mostly being met by fossil fuels like coal and oil. Both of these energy sources are responsible for a lot of the toxic carbon dioxide that is currently in our atmosphere and it is because of these carbon dioxide emissions that scientists are growing increasingly concerned with its impact on our environment.

Because people do not realize how their normal electrical usage can affect the climate in such a strong way, they are not as concerned about trying to find alternatives.  However, the importance for finding clean, renewable, sustainable forms of energy has never been more important.  Apart from the fact that the energy sources we use now could harm the atmosphere, the fact is that they are not renewable and eventually at the rate at which we are consuming the energy, we will soon run out.  This is probably the most pressing reason behind our need to find alternative sources of energy.

Right now energy companies have been exploring the options for using solar and wind energy on a wider basis than is currently being used.  Dams are also a great source for hydro power but are only good in areas with lakes and rivers that can be confined and used as a source of energy.  Likewise, wind energy can only be harnessed in areas where there are consistently moderate wind gusts, so a lot of areas which do not fall into this category might not have access to enough wind energy to sustain their power needs.

Right now researchers all over the globe are trying to find alternative energy sources.  The most common yet controversial form of energy that does not release carbon dioxide into the atmosphere is nuclear power, but concerns over the dangers of contamination and melt downs have kept nuclear power from developing on a larger scale.  Nuclear power may be a clean form of energy but is not without its share of downfalls, it produces harmful nuclear waste which takes millions of years to break down which can only be stored.  This is problematic considering we only have so much land for storage and being contained in this way, the nuclear byproducts could eventually leach into the environment.

Until something is discovered that can provide enough sustainable and reliable energy without releasing large amounts of carbon dioxide into the air, the best alternative is to try to cut back on  energy usage on a consistent basis.  Research has shown that if everyone just took the time to turn off the lights in their homes when they were not in use, that it would help to cut back the amount of energy being used by up to twenty five percent. Even simple things can make a huge difference.
