Understanding How You Can Help With Wind Power

February 6th, 2010

It seems that more and more people are really starting to take notice on ways that they cannot only save money but also save the environment. Many people have for years fought against drastic action against such ideas stating that they were simply too costly to make it a reality.

The cost of installing a wind generator is a lot less than you may think and it quickly pays for itself by saving you a lot of money on your electricity bill. There are also a variety of incentive programs to encourage people to switch to alternative energies. These programs may allow you to be reimbursed for part of the cost of installing your wind generator.

We’re all interested in preserving our environment, so there are plenty of programs in place to encourage people to start using wind power. You’ll save money over time by installing a wind generator too. You’ll save on energy costs, as well as being able to sell power which you don’t use to your local utility company.

Electric companies are required to buy surplus electricity which their customers generate by means of alternative energy technologies. You’ll not only be powering your home, but also supplying clean, renewable energy to other homes in your city!

You can even make a little bit of money by using wind power, so everyone wins here. Wind generators are easy to install as well. You can find instructions which take you step by step through the process on installation, so there’s no need to worry. It’s easy enough for anyone to do and if you’re installing your generators in your roof, you should be able to generate enough energy to meet your home’s energy needs.

What about a back up plan? If you live somewhere where they can be times of very little wind, you can fall back on the utility company. Simply do not disconnect your hook up to the electric company just in case you ever need to fall back on them. This will ensure that you are never left without the electricity you need to run your home in a safe and pleasurable way.

This does not mean that you are not truly making a difference though. Every day that you are able to run your home off of wind power, that is one day you are not using the energy produced by the electric company. Of course, the large the wind turbine you install, the more wind you will be able to capture and turn into usable energy within your home.

This does not mean that you have to go with the largest that is out there though if that is not something you can afford at this time. Over time, you can add more and more generators, or larger ones, and you will be able to see that you are bringing in much more renewable energy.

See how you can build residential wind turbines for your own house and save cash on your electric bill. Making your own wind power generators may save you hundreds on the cost of buying one at the store as well and still make lots of power.

What Is Wind Power

December 19th, 2009

Since the importance of protecting our environment is now well known, a lot of people are interested in using alternative sources of energy, especially wind power. What a lot of us don’t know is how wind power works. Wind power works very simply; the movement of the wind is used to turn the rotors of wind turbines and this kinetic energy is then turned into electricity.

Even though wind power is a great source of unlimited clean energy, it is used to produce a mere 1.5% of the world’s electricity. With every year, though, it is becoming more widely used.

The more people know about the danger posed by continuing to produce electricity by conventional means and the benefits of wind power, the more people are interested in making the transition. There are some countries which have made great advances in the use of this alternative energy technology; Denmark already uses wind power to meet 20% of its electrical energy needs.

Portugal and Spain have able eleven percent wind power usage. And it is seven percent in the Republic of Ireland and Germany. Even though it would seem like a natural transition being wind power has historically been used for pumping water, grinding grain and propelling sailing ships, it has only been until the recent years that it was being used for the production of energy that can be used as electricity.

It is true that some people say that wind farms are less than attractive – but given all of the benefits they have to offer, it’s easy to come to terms with the aesthetics of wind power. Wind power does not produce pollution and provides clean and renewable energy.

There is even more that wind power may be able to do besides powering our homes and businesses. A car has been built which uses wind power and can reach speeds of more than 100 mph! While these cars won’t be on the consumer market for at least a few years yet, this is a very exciting application for wind power.

These cars use a solar-charged battery to start, but once they’re on the road, they run on the kinetic energy of air circulation! Wind power could be the answer to many different energy problems faced by the world. It can power our homes and someday may even run our vehicles; there are few, if any downsides to using wind power.

Of course, some who live near a wind farm do have some complaints about the noise, but other neighbors of wind farms shrug it off, saying that these wind power plants produce less noise than a herd of sheep or cows would.

Whether wind farms or regular farms are noisier is a matter of debate. However, it is hoped that adopting this alternative energy will be done in the interests of society and protecting the environment, rather than on the basis of what the neighbors will think.

Looking to learn how to build a wind generator? It’s simple and you can build a strong turbine that is cheap to build. Learning how to build a home wind turbine can eliminate your hydro bill and help the environment, too.

Wind Power: Good For The Environment, Great For Your Wallet

October 22nd, 2009

There are a lot of good arguments for using wind power to meet our needs for electricity. Since producing this energy from fossil fuels is so harmful to our environment, it only makes sense to start exploring the possibility of using other means to provide the electrical power we need.

There is a growing awareness of the importance of conserving nonrenewable resources and protecting the environment; and with it, an increasing interest in the use of wind power. Installing wind generators allows you to power your home without using as much (or in some cases, any) energy from fossil fuel burning power plants.

Of course, while you should have no problem generating a lot of power, you will not want to cut off your connection to the electric company. The electric company can serve as a back up source should your wind generators not provide enough power for you during some non-windy times.

When there are good winds, you’ll make more power than you need; this excess can be sold to your electric company. You won’t become a millionaire this way, but it’s one way that your wind generators will more than pay for themselves (and you can watch your electric meter turn backwards – how cool is that?).

Wind power is a great way to do your part to preserve the environment. While there is an expense involved in installing wind generators, they will more than pay for themselves over time with the savings they’ll give you on your energy bills.

Some states have programs to reimburse you for a lot of your expenses with the installation of the wind generators. Even if there are not any programs that you are able to get, the shear fact that your electric bill will decrease by a lot of money means that over time, the expense of installation will have paid for itself. After that, you are truly looking at free energy.

They’re easy to install and there’s no need to hire a contractor for the job – this is something you can do yourself! Hiring a contractor is expensive and it’s really not necessary. This is easier than a lot of the DIY projects you’ve probably already done, in fact.

You’ll just need some standard tools and some well written instructions. There is plenty of material available in the web which can help you get started, including step by step instructions which take all of the guesswork out of installing a wind generator. You can have your wind generator installed and producing clean, renewable electrical energy for your home in no time!

Looking for something that can show you to build residential wind power fast and cheaply? This is a great place to start. You’ll see how you can build wind generators in your yard to save your hard earned dollars.

DIY Wind Turbines – Cheap Energy

October 20th, 2009

The cost of maintaining your household can be staggering. One of the larger expenses for any home is of course the cost of electricity. Many people find themselves budgeting carefully for this expense and trying as hard as possible to conserve energy to keep pace with the increasing cost of energy.

There are some bills which you really can’t do too much about; your mortgage or rent aren’t going to decrease and you most likely need your cell phone and internet access too much to cut back on these bills. You can save in a lot of ways, but many expenses are simply unavoidable.

One of the important utility bills that most people fail to lessen are the electric bills. Even if you spend additional time unplugging unused devices to save electricity or force yourself to switch of the lights when you don’t need them, you can still get tired with the efforts that need to be done. It also becomes tough to follow if you live with other people who may not be as interested to conserve electricity.

The answer isn’t necessarily to use less electricity, but to get it from clean, renewable alternative energy technologies. You can reduce the amount of power you buy from your local utility company and you may even be able to replace all of this electricity with power you can generate yourself!

Solar and wind are the most popular alternative energy technologies. You probably know the basics about solar power already. It’s a great non-polluting energy source. Wind power is something you’ve probably not really considered for your home, thinking you’d need a huge wind farm in order to get the electrical power your home needs.

It’s actually a lot simpler than all that. With just a couple of wind turbines installed on your rooftop, you can save a lot of money on your energy costs. Wind turbines are easy to build and you can get the materials cheaply online or locally at junkyards and other sources.

Properly installed wind turbines on your rooftop can work extremely well during windy days and can power a number of devices giving you some independence to your normal source or electricity. This should significantly reduce your electric bills when used every day. The results are even better if you create many wind turbines as the power generation can be much greater in groups.

The way that a wind turbine works is simple – the kinetic energy generated by the rotors moving in the wind is converted into electrical energy which you can use in your home. Best of all, your wind turbines generate power day and night; unlike a solar panel. Excess energy can be stored in batteries and used later.

These wind turbines aren’t suitable for all households most specifically the homes in urban areas, but for other people, they remain as more cost effective alternatives since the materials that are required are cheap and accessible making wind electricity more reliable for people on tight budgets.

See how you can build diy wind power for your own house and save money on your power bill. Building your own wind power generators can save you thousands on the cost of buying one at the store as well and still make lots of power.

How to Build A Wind Generator At Home

October 9th, 2009

Fossil fuels and non-renewable energy sources cannot last forever. We are simply running out of them, and prices are skyrocketing. We need to change the way we use energy and the way we generate energy in order to make sure our lifestyle remains sustainable over the long-term.

There are some people who have already started thinking this way. New scientific breakthroughs in renewable energy are allowing us to create sustainable energy at lower and lower costs.

With the right plans, even homeowners who currently don’t know a thing about producing their own energy can make energy by installing their own renewable energy sources, like wind power generators.

Wind turbines can be made to reduce the average home’s electricity bill by as much as 70%. They can be built, using economical plans, for as little as $200 using pre-used parts. The most expensive part might be a DC motor which can cost as little as $30.

They can also be built with materials from a local hardware store and basic tools. An easy way to estimate how much power your wind generator can create:

Power(Watts) = (Wind Speed)^3 * (Blade Diameter)^2 * 0.00478

The speed of the wind makes the most difference, because it’s value is to the power of 3 in the formula. An example calculation for a wind power generator using a good wind speed (10mph) and blade diameter (8ft):

W = (10*10*10) * (8*8) * 0.00478 = 305 watts/hour – x 24 hours and you can calculate 7.3 kWh generated per day by a wind power generator.

An average home uses about 12-20 kWh/day. Of course if you conserve your power you can reduce that to much less – even down to 5 kWh per day. So if you don’t have a great average wind speed in your area, a wind power generator can significantly reduce your power bill, and it may only cost you $200.

Wind Power Generators – Inexpensive Power Alternative

October 6th, 2009

Power and fuel costs are rising, and many people are looking to stop depending on energy companies. Wind power generators are a source of free power and are becoming much more readily available. They are expensive to buy, but luckily there is another option.

Building your own wind generator into your home is easy. The rule of thumb is to find a place that is about 200-300ft from another obstacle or at least 20 ft higher. In North America the average wind speed is around 9m/s, which can give you a lot of power.

Wind power is a great source of renewable energy. It is much cheaper than solar power per Watt, as a wind turbine can generate 1000W while a single solar panel generates around 100 in daylight.

To turn the rotational energy of the turbine into electricity, the actual power generator is the DC motor. You will have to pick one up or order one – they can cost $50 on up depending on size.

You will also need to buy a tower, or improvise one. Recycling towers is a good idea – people that have old TV towers they don’t use any more may actually pay you to take them away. You will also need some great engineering blueprints to get you started on your project.

Some individuals have build their own 500 watt systems, using homemade wind blades from large PVC, (5 foot wind generator, so blades about 30 inches in length for 500 watts), DC Motor, Recycling TV Antenna towers, and the batteries for the bank to hold the generated power. These homemade systems can be made for under $400. You can buy kits that run around $3500-$4000, up to around $15,000 depending on the watts output.

The basics of wind power generators have been around ever since the old windmills you still see at farms across the plains and prairies. Now you can find plans on the Internet for building your own system, or buy components or kits that contain what you need to know.

Anybody that has over a half acre of land, some PVC, a motor, some batteries, and either a tall TV Antenna, or some 2 or 3 inch steel to build a tower, can put together their own wind power generator, with basic tools.

How To Start With Residential Wind Power

October 3rd, 2009

Whether you want to get set up to live off the grid or just want to experiment with getting some extra power to keep down your energy bills, building your own residential wind power system is something you need to look into.

So why don’t you and your neighbors go out and buy some turbines? Because commercial ones can retail for exorbitant prices – $2000 to $6000, even. They are still worth the money because they last for a long time and in a year or two they have paid for themselves, but there is an alternative.

If you have the right plans you can build your own, in fact. And it’s not complicated, and it’s not expensive. you can do it for around $150-$300 depending on the amount of power you want to produce.

What will you need to make your own wind generator?

First you will need a good set of plans, an area to work in such as a garage, common tools, and about four days to complete the job.

The components of a wind generator:

There are four main parts – the blades and hub, the body and DC motor, the tail and the tower. It takes the longest to build the blades and the hub of the system, though it is still fairly simple.

You will have to order the motor for the wind generator. Your plans will tell you where to get the motor, what size you need and all the technical stuff you need to know to be sure you get what you need. It is the most important part as it is what converts the wind power into electric to power your home.

For the body it is best to use double walled stainless steel like that from a chimney pipe or wood stove. It is very cheap and easy to get and will last a long time.

The tail is simple and can be made almost any way you like and decorated anyway you choose.

For the tower, you can either build it from scratch too out of piping or recycle something like an old TV tower. People who have them in their yards may actually pay you to take them away.

Now that you know some of the basics, you can see that it’s not that complicated or expensive to have your own residential wind power system to run your household. All you need now are the plans to get started.

Wind Power Solution – For Your Backyard

October 1st, 2009

Power and fuel costs are just starting to skyrocket, and they are only going to get higher as the shortage of oil gets worse and demand goes up. Conserving energy is our next priority as a nation, but we can also go one step further to ensure that we never face an energy crisis again – start to create our own renewable energy. Solar power and wind power at home is becoming a common thing and it is becoming very cheap, especially if you create your own solar and wind power generators.

These solutions can help you combat power outages, reduce your electricity bills, and also help the environment.

Wind power solutions work best when the following conditions are met:

- Your property is about an acre in size or bigger, or building around your property aren’t very tall.

- The average wind speed in your area is around 11 miles per hour. If you stay in a place that has little wind flow, your system will not work. Consult an expert before installing the wind power solution at home.

- Your house needs a lot of uninterrupted power supply. Combating those power outages is easy with the pollution-free wind power systems. You need no longer worry about a break in your work because of a power uncertainty.

A typical wind power system comprises of a tower and wind blades to churn out wind energy. The length of the wind tower varies depending on the location of your house. You may need a longer tower if you are in low-wind zone; you can work with a shorter tower if you live by the beach.

The spinning energy of the blades is converted into useful electricity by a motor inside the wind turbine. This electricity can be used to power your household appliances. If you use batteries, you can get off the grid completely or just store energy for later in case of a power blackout. If you stay on the grid, your power company will pay you for energy generated that you didn’t use!
