A wind turbine uses its rotor blades to generate power by converting the wind’s natural kinetic energy to a usable form i.e. mainly electrical energy and at times mechanical energy. A large group of turbines set up at a given location constitute a wind farm. These wind farms are aimed to produce energy in a way that is environmentally friendly and economically viable. Major utilities, as well as, individual owned energy suppliers, home owners, farmers, and ranch owners are now taking advantage of this technology. Issues to be analyzed are the space required for the installations of these wind turbines and the feasibility and usage of the amount of power generated.

Amount of energy generated by a wind turbine

The unit of measurement used to quantify the energy generated and supplied by wind turbines or other power generators is the watt. Most modern day, utility size wind turbines offer a range of around 700 kilowatts to 5 megawatts (5,000 kilowatts) of capacity, also known as the turbine’s nameplate capacity. A one megawatt wind turbine typically generates anywhere from 25 to 35 percent of its nameplate capacity in output, depending on the location where it is erected. This is due to the fact that wind characteristics and speeds vary by location, and the natural downtime associated when no wind is present. The actual amount of power generated by a turbine at a given location versus its nameplate capacity, when measured as a percentage, is known as the capacity factor. Therefore, a 1MW turbine sited on a section of land that yields a 30% capacity factor would generate 1,000kW * 365 days/ year * 24 hours/ day * 0.30 = 2,628,000 kWh of electricity. An average household in the United States consumes approximately 10,655 kilowatt hours of electricity annually. Therefore, as many as 250 households (dividing 2,628,000 kWh by 10,655 kWh) can be powered in a year with just 1MW of wind energy.

Space required for a wind plant / farm

The amount of land required for a wind farm depends on the kind of geographical location it is installed at. A large scale wind farm on a wide, flat piece of land would require approximately fifty acres of space per installed megawatt of capacity. However, the positive aspect is that less than five percent of this land is used for the actual operation i.e. connecting roads, wind turbine towers, equipment, and machinery. Thus more than 90% could be used for multiple ancillary activities, such as farming and other agricultural purposes, due to the spacing between the turbines. This makes a wind energy project financially beneficial and multi-functional to land owners. Consequently, farmers, ranchers, and land owners in many states have leased their land to energy providers for a royalty premium; making it a great way to earn additional income. The area required for a wind farm in windier locations such as rugged, hilly areas and offshore wind farms requires less land; sometimes as low as five to ten acres per megawatt.

Using homemade solar cells which you can make yourself on a budget for around $100, you can easily harness renewable energy to power your home with. But that’s not all that you can gain from using renewable energy. Here are four ways to save and make money using renewable energy.

Power bills-I just mention this in opening, but when you consider that the average American household spends $200 on average each month on utility bills alone, this is a figure which should not be overlooked. Imagine having an extra $2500 in your annual budget because you generate your own electricity without having to do a thing. That’s money that could undoubtedly be better spent elsewhere.

Tax breaks-the government is very generous when it comes to those who rely on renewable energy. These people are helping to save the government money in the long-run because there is less need for finite energy sources, not to mention that these people are helping to alleviate the greater energy crisis and concerns which our nation faces. The IRS issues these people tax breaks, so remember this come tax season.

Home value-other homeowners are interested in saving and making money just as you are. Having solar cells attach to your home when you sell it significantly adds to its value. So keep this in mind when it comes time to sell and ask your realtor about it.

Extra energy-using DIY energy guides, you can easily build your own solar cells. Many homeowners who do this go on to construct multiple solar cells. Why do this? Because for every bit of energy which you produce but do not consume in any given month, you can sell all that energy back to the power company for profit. Imagine making an exit $2500 each year without having to do anything beyond constructing a few extra solar cells one afternoon?

Many companies and homeowners with extra land to devote to it line their land with solar cells with the sole purpose of creating moneymaking energy and bring in a very attractive secondary or even primary income this way. The best part about it is that it’s entirely automated and it’s income for life, not to mention that it’s entirely up to you as to how much energy which you produce

It could be "all the rage" today to jump on the bandwagon and need to use replenish-able energy to help save the planet, but in reality, how do you use the earth’s renewable resources and save cash on our own energy costs? How does one basically get to employ a renewable energy like the sun or wind to power your home? Do you get a professional installer to put up some solar energy panels or a wind energy generator? Will you take the leap and try to do it yourself and hope you actually finish the project and end up with a usable system? There are many questions about this topic but we will try to give you some answers.

Good stories is, green energy is rising and that makes it simpler for the typical person to setup and install your own clean energy system.

The truth is that it isn’t hard not hard to build wind turbines and many homeowners are taking the challenge to build their own wind turbines as an inexpensive means to using renewable energies. It isn’t exactly snap-your-fingers straightforward to build wind turbines either, but with the proper plans and a galvanized builder you can be building air turbines in no time.

When the wind dies down (or doesn’t exist at all) then solar energy panels are a great option and frequently solar energy panels and wind energy generators are used together to generate a home’s power. Solar electricity is an example of the finest and most trustworthy replenish-able energy sources available. The difficulty most amateur environmental soldiers find is that the cost of professionally installed solar power systems is way outside their budget and it could take well over ten years to see a return on their investment.

You might be thinking that building wind turbines and/or solar cells on your own will cost thousands of dollars much like a professional system. You would be stunned just how inexpensive building your own solar or wind energy system can be. With the right plans, you can build your own wind energy generator for between $180-200 and less if you can find some pieces to recycle from other used apparatus, as an example. The key is to discover a plan that works for your goals.

There are numerous different DIY plans available online today. You need to make sure that you get complete plans that include

? Complete instructions and diagrams

? resources to get certain parts you can need ( best to avoid plans that require purchasing parts from specialised internet sites since this can cost extra money )

The key to keeping costs down and completing any project lies in good planning, and the right manual will help you do just that. Look for proven, experienced and moderately priced replenish-able energy manuals. You do not have to spend hundreds, and some of the finest manuals available are terribly creative in their use of materials found at your local hardware store or by employing recycled materials.

So, for a little bit of elbow grease, you can make your own electricity for years ahead, help the environment and save money with a " renewable energy system.
.

The most popular forms of rural electric renewable energy in the world today are both wind and solar power. You can build your own electric generators out of materials found in your local hardware store.

Solar and wind rural electric renewable energy are uncomplicated and can be set up in just a weekend. If saving money while setting up your own renewable power system is important to you, you will definitely want to consider building your own system.

If you look at what retail solar panels cost it’s around $4(USD) per watt. Now, if I can build my own 100 watt panel with deep-cycle battery, charge controller and inverter for around $200 – $250 in parts… Is it not worth researching?

The whole rural electric renewable energy project can be completed in a weekend if you have the time to devote to it. If you have a semi busy schedule you could finish it in a week. But, no matter how long it takes, you will get a much better watt per dollar ratio with a panel you build yourself.

Homemade power systems can supply rural electric renewable energy for an affordable price. The high quality solar panels and windmills you produce can generate as much power as you wish. It all depends on how big you want to build your system.

In a world where electricity costs are on a consistent uptrend, rural electric renewable energy is only gaining value. In this day and age the know how to building your own energy systems for homes is extremely valuable knowledge.

What is a wind turbine?

A wind turbine is also referred to as a windmill or wind generator. Though the terms are used interchangeably, there is a minor difference. The wind turbine is the device that makes use of the wind energy to produce mechanical energy. This mechanical energy is then used as is or converted into electrical energy. A windmill uses the mechanical energy as is for pumping out water or for grinding purposes whereas the wind generator is the one that produces electrical energy.

What are the different types of wind turbines?

Wind turbines are classified into two kinds based on their orientation:

• Horizontal axis turbines – The blades in these wind turbines rotate along a horizontal axis.

• Vertical axis turbines – The blades in these turbines rotate along a vertical axis.

The horizontal axis wind turbines are more commonly used. They are more efficient that vertical axis turbines.

What are the advantages of installing a wind turbine?

Let’s look at the major advantages of a wind turbine:

• Power-saving: Since the wind turbines use a free energy, the wind energy, they prove to be a very cost-effective mechanism for generating electricity, thus helping not only save power but also generate power for the world.

• Cost-effective: The only cost involved in installing a wind turbine is the initial cost and the cost of maintenance. The energy comes free and there is no other fuel.

• Environment-friendly: The wind turbines are environment friendly in a way that they do emit harmful gases or affect the environment in any way.

• Uninterrupted power supply: A wind generator helps you become independent of government’s electricity supply. Moreover, you overcome the hurdles of power outages.

What are the factors you should consider for installing a wind turbine?
While installing a wind turbine is extremely beneficial for you and for the rest of the world, you must take care not to implement the solution in an incorrect way. You should take into consideration the following when installing a wind turbine.

Make sure the following two pre-requisites are met:

• The site for installation is at least of one acre area.

• The average wind speed is around 11 miles per hour.

• Make sure the tower and the base are sturdy. It is important to foresee the turbulence in the wind before you invest in the wind turbine.

• Make sure the tower’s height and the distance between the wind generator and the cells are optimum.

As political and commercial facets of fossil fuels grow more harrowing, renewable energy is becoming more popular. Here?s an helicopter view of renewable energy.

Renewable Energy Overview

Renewable energy is tougher to outline than you may imagine. Since it is a catchall phrase for a number of power sources, any definition needs to be broad. With this under consideration, let?s define green energy as any power source that naturally occurs and is extraordinarily abundant.

Ironically, just about all clean energy sources rely on nuclear power. Fortunately, the nuclear power is in the shape of the sun at the center of our solar system. One giant nuclear reaction, the sun produces solar energy and sunlight that is converted on our planet into energy thru natural resources. In one form or another, sunlight is the base for solar power, wind energy, biomass power, and so on. Carbon-based fuels, on the other hand, are a kind of biomass energy, but a traditional one with resource boundaries and brutal side effects in the shape of pollutants.

Solar Energy is the most elementary and direct form of replenish-able energy. Relying on the kind of platform used, sunlight is converted right into electricity or heat. years. Once the sun burns out, we are going to have much larger problems than energy!

Wind energy is another form of solar energy. You intrinsically are mindful of this if you concentrate on the temperature differences when standing on a black carpark vs grass in a park. Air above a hot surface will rise and less warm air from surrounding areas will dive into to fill the gap. This temperature-induced movement creates wind in its most simple form.

Modern wind turbines are between 25 and 35 % efficient at changing wind power into electricity. Wind energy into electricity.

When water moves, it tends to carry a lot of inertia and stored energy. On a less disastrous learned to use the power of moving water to produce electricity. Often seen on big projects, hydropower generally is employed in the shape of dams. A dam is placed in a brook, making a reservoir. Using gravity, water is then released thru pipes in the dam.

This is starting to change. The basic concept is very similar to to hydropower. Although the tides move comparatively slowly, the contain massive amounts of energy. Once thought an odd energy concept, tidal energy is coming on powerful as an energy platform in Europe.

By exchanging liquids between above and below ground areas, temperature regulation can be done. This is typically seen in residential situations.

Biomass energy is a clean energy source, but not always a clean one. The concept behind biomass energy is to convert the chemical energy in the biomass into usable power. This regularly happens by burning it, which is cryptic since doing so causes pollution. It also needs to be grown, cropped and converted into power. Of all the clean energy sources, biomass is the least attractive.

We have lots of options when it comes to kicking the fossil fuel habit. Although there’s a chance one of these options will become dominant, it is more likely that a combination of all the above green energy platforms will be the answer.

The Sun and Wind Your Only Choices

There are legitimate reasons to go off grid. Anyone who lives in very rural or remote areas, knows to well about the advantages and disadvantages of going off grid. The costs of local utilities are so high, in most cases it is not a question of going green but rather a purely financial one. Whatever your reason for researching off grid power, your options have now turned green. Solar and/or wind energy are the only options available in this case. Your best bet is solar, unless the area you are looking into is a windy one. Even in that case, I still recommend that solar power be your main source of off grid energy.  Did you know that the small amount that hits your roof, greatly surpasses all the energy that is transported through the utility company electric wires? That is the reason many people who have  switched over to solar power, either go off grid, or sell back to the utility companies for a profit. It is for that reason, installation of a proper system can more than handle all your electricity needs.

There is a reason I prefer solar to wind, when it comes to household energy requirements. Both solar panels and wind turbine rotors are considered to be a form of a collector. Naturally one can see that the area of just one solar panel is much greater than the surface of a small wind rotor with a number of blades  that rotate to turn the electrical generator. While both offer a renewable non- polluting source of energy, it should be noted that solar  has no moving parts to break down, and requires very little maintenance. To properly access  wind flow and generate enough electricity, wind turbines are installed on high towers that rise above any trees or surrounding buildings. It is advisable to get your neighbors permission before installing such a structure. For whatever reason you chose not to have a high enough tower, it won’t matter when it comes to generating adequate energy. It is better not to install a wind turbine in the first place, rather than to not have it high enough. There is simply little energy in low winds that you can convert into usable electricity.

The Sun Will Always Shine

Off Grid Solar Is the Future
Today we are finally realizing that the future of the Earth depends on weaning mankind off of petroleum and other fossil fuels. Here is another fact that will astound you. The entire total of  fossil fuels on Earth can be matched by the solar energy output of the sun on Earth, in less than three days. It is not politics and greed alone that has kept us from pursuing solar energy until recent times. The technology for home solar has greatly improved.  It started in the mid 1970′s, with the advancements in Photovoltaic applications. Photovoltaic, also referred to as PV, is according to  Wikipedia, the field of technology and research related to the application of solar cells for energy by converting solar energy (sunlight, including ultra violet radiation) directly into electricity. The development of transistor and accompanying semiconductor technology, has drastically  increased photovoltaic power and efficiency.  Today, commonly available solar panels are 12% efficient, which is four times greater than only a few years ago.

Another very important aspect is that contrary to most contractors’ misconception it is not a difficult installation. An average home has more than enough roof area to produce enough solar electricity to supply all of its power needs. All that is needed is an inverter,  which converts direct current (DC) power from the solar cells to alternating current (AC), which are what most home appliances run on. A solar home, except for the obvious changes to the roof, will look and operate just like any home does when it was connected to the power line.

Let the Sun Free You From the Grid

Do-It- Yourself and Save
There is another misconception that needs clearing up. You should know is that contrary to popular belief, residential solar installation is very affordable. You don’t need to hire a builder or solar contractor, which could run you tens of thousands of dollars. With the correct instruction and guidance you can do-it-yourself. You must be careful however, because many instructional books and guides are  confusing and have complicated diagrams. So before getting started you must find the correct step-by-step instructions. You don’t need to be a builder.  Anybody can make solar panels. It’s really quite easy to make solar panels once you know a few industry secrets. You must make sure that the guide you chose has step by step instruction, detailed diagrams, plenty of pictures and video teaching aids.

So how much will it actually cost to make your own solar panels?  You can, with the right instruction, build your solar panels for less than $200 each. I suggest that if you don’t have the time or you’re just not willing to put in the effort, you can hire a couple of competent handy men to implement the project, and still save thousands. Real people, not corporations, have come up with efficient and extremely affordable programs that walk you through step by step instructions, on how to build and install renewable energy for your home.

My own extensive research has helped me narrow down the best of the best instructional guides, complete with blueprints, photos, and in the case of my number one choice, video for that do-it-yourself solar power and/or wind turbine project you might be considering. Obviously, I can’t go into great detail in this article, but if I have piqued your interest, you can get all the facts of this or many other ideas on how to go green at my site  Possibly GREEN. There you’ll find the right ways to live a greener life, including information on how to convert your car inexpensively, and even find green jobs in your area.

Currently, there is a bad economic crisis all over the world. Therefore, it would be wise to think of ways to save your money especially in the end. Using renewable energy sources for electricity production is one such way.

For those who are not familiar with the term renewable energy source, well, it refers to natural energy sources like the Sun, wind and water. What is great about using such sources? Apart from the possibility of saving your money as time goes on, you also help save the environment.

In order to supply the demand of electricity by people, power supply plants generate more electricity. This means more consumption of petrol and release of by-products that are not environmentally friendly. As it is, it has been noted that the ozone layer of the world has depleted.

Therefore, it is important for everyone to play a role in saving the environment. You have two main options of using renewable energy for electricity production. You can use the energy from the Sun called the solar energy or the energy from the wind called the wind energy.

There will be some expenditure when you initially set up the necessary equipment like solar energy panels for solar energy or wind energy turbine systems for wind energy. However, you do not spend much money for maintenance as is in the case of electricity cables and wiring for your home. Therefore, in the end, you do save some amount of money.

If you generate excess electricity or more than you need for your home, then, you can sell it to others. In such a case, you may even get back your capital or the amount of money you spent for buying and setting up the necessary renewable energy equipment. Perhaps, you can even make a small side income for you and your family.

Research into renewable energy has been getting a lot of attention recently due to the confluence of a few factors. One is the unmistakable rise in global temperatures brought about man’s activities, mainly through the burning of fossil fuels. Second is the pollution caused that is harming both environment and human health. Last, a significant factor is economics and politics. No longer is the world willing to be beholden to a few states holding the key to most of the world’s reserves of oil. The ever-increasing price of oil makes the economic feasibility of renewables work.

There are a few types of renewable sources of energy that are under the process of development and commercialization.

These include:

1. Solar
2. Wind
3. Hydropower
4. Nuclear
5. Tidal
6. Geothermal
7. Biomass

Although it is good to develop sources of renewables, the current trend is towards the “aesthetics of green” where solar panels and wind turbines carelessly applied onto a project and are labeled as green. This is not only self-congratulatory but also self-deluding.

The technology behind renewable energy is important, but the application of such technology is what is primarily missing right now. The application of renewable technology has to answer three basic questions:

1. Does the technology require any special environmental condition or resource? Does the site possess such a condition for the technology to function to it’s designed intent?
2. If so, can that condition or resource be provided ay little or no cost?
3. Does the technology have scalability?

For example, geothermal would require regions with active volcanic activity. Without this condition, the technology will fail. This may look simple, but it’s often overlooked. This is especially the case for wind and tidal technologies. At some locations, there is simply not enough wind or differences between tidal conditions for the technology to be feasible, but people still go ahead by implementing them anyway.

The 2nd question is sounds like a no-brainer, but often it is also overlooked. Solar power is produced by the sun. Hence it can be considered free. But again, problems arise with regards to unstable sources like wind. To address that issue, some inventors have proposed placing wind turbines to tap the winds of passing cars or from the exhaust of air-conditioning units. They neglect the fact that the energy of the cars and to run the exhaust fans come from the burning of fossil fuels, and the cars and fans have to work so much more harder just to counter that extra air resistance and run the turbines. What they are doing is just vampirism. More energy would be spent creating that condition than is recovered.

The final question is with regards to applicability. Some renewables are more suited for large scales, but some have the flexibility of scale. Comparing a hydropower dam to solar panels, the differences are obvious. Hence, there is need to match the type of technology to the type of building.

What is a wind generator?

A wind generator is a machine that uses wind energy to produce electrical energy. It captures wind energy and converts it into mechanical energy that moves the blades of a motor to produce electrical energy. Wind generators help produce thousands of megawatts of electricity. They are also a very popular power solution for individual farms. They are ideal for large areas with good wind speed.

Setting up a home wind generator does not need professional help; individuals can easily set it up with the help of numerous guides available in the market. The components of a wind generator are also easily available in the market.

How does a wind generator differ from a windmill or wind turbine?

Wind generators have been in use for a long time in the form of windmills or wind turbines. Years ago, when electricity was not invented, wind turbines were used to pull boats and pump out water.

Even now, the terms, wind generator, windmill, and wind turbine are used to refer to the same device.

What are the advantages of using a wind generator?
The advantages of a wind generator are many. Let’s look at a few of them.

Environment-friendly: Wind generators prove to be environment-friendly in two ways:

• They do not emit harmful gases in the atmosphere nor do they leave any harmful residual component.

• They do not use any fuel to produce electricity, thereby helping the cause of the environment.

Power-saver: Wind generators are an alternative power solution. They do not use any non-renewable sources of energy, thus helping in times of energy crisis.

Economical: Though the initial cost of setting up a wind generator seems high, the cost of generating electricity in the long run becomes nil. So, you will be getting electricity absolutely free after a few years.

Independent option: Wind generators do away with the dependence on power plants and the government for electricity. With a wind generator in your land, you have your own power plant for life.

24/7 power: With wind generators, you can say bye to power outages forever. You will get continuous, uninterrupted power supply for your entire house and land.

Power storage: A wind generator also allows you to store power for use later. This feature makes it an amazingly lucrative power solution.

If you want to help the world and fight the current energy crisis, invest in a wind generator.
