Small Wind Generators You Build Yourself

As our society matures and we begin to understand and appreciate that everything we do will have an impact on our environment, we are starting to look for better ways of suppling our energy needs. Using wind turbines might just be one of those alternative sources of energy. Harnessing the power of the wind is nothing new, and now both countries around the world and the typical homeowner can produce electricity using the wind and household wind turbines.

Converting wind energy into electricity is done with a wind turbine. You’ve probably seen these behemoths in fields across the country. Recent advances in the technology have made it possible to downsize the turbines and make them viable for home use. If you’ve been noticing funny looking ‘wind mill’ things popping up in your neighborhood, you may have wondered if your neighbors have lost their minds or if they just know something you don’t. The truth is that there are wind turbines made especially for home use which are small enough to be mounted in the backyard or on a roof.

For those interested in purchasing a wind turbine and having it installed, it will cost you between $600 and $12,000. That’s a big expenditure for most people. And with a projected energy savings of about 80% it would take quite a long time to recoup your investment. However, it is now possible to build a wind turbine yourself for just a few hundred dollars.

More and more homeowners have decided to build a wind turbine. It is far easier than you might have imagined. The supplies you need to build a wind turbine can be found in any hardware store and will cost about $200, and the whole building process won’t take more than a few days. A good instruction manual with easy to follow directions will guide you every step of the way.

Since one turbine can be enough to generate almost 60% of the electricity you’ll need for your home, you can start to realize significant savings. Every day your wind turbine is working means another day of savings.

So if you’ve been thinking about ways to cut your utility bill and are intrigued by the idea of using energy windmills to harness wind energy and save some money, you are not alone. Give it a try. You will be pleasantly surprised at how much you can save.

Solar Energy is a Form of Green Energy Source

Solar energy is a green energy source because it is a renewable and it does not cause any harm to the environment. This is achieved by converting the sun’s rays into electricity with the help of solar cells.

There are three basic approaches how we can use this form of green energy source namely passive, active and by using photovoltaic cells.

When we refer to passive solar energy, nothing is converted. What happens is the building’s design helps avoid heat loss and gets the most out of day lighting.

Such a technique can also be used in homes because studies have shown that this can reduce the heating requirements by as much as 80% with minimal cost. This means you don’t have to turn on the air condition or heater that often and if everyone does that, we don’t consume that much electricity which we get from non-renewable resources.

The second approach which is active solar energy is the first way of converting sunlight into heat. You should know that there are certain limits to this one and all it can do is make sure you have hot water.

The third approach is the big scale version and it can power an office or an entire home. This is done with the help of solar cells that convert sunlight into electricity. The smallest ones around can be seen in calculators and watches with large ones planted over huge acres of land.

The only limitation to this green energy source is the fact that it can only generate power when the weather is good and the sun is out. Should it rain, then nothing is collected and converted. When this happens, the auxiliary system is turned on until the weather improves.

Despite that, scientists and students themselves have made solar powered cars. NASA or the National Aeronautical Space Administration has sent satellites into space that are powered by solar panels. A fully functional airport can function on its own thanks to solar power even if it is situated in the middle of the frozen desert.

So people can see the awesome power of solar energy, did you know a kilowatt of solar energy can produce 5.5 hours of electricity per day. If you have more solar cells in place, naturally you will be able to produce enough power to last several days.

Solar energy is just one form of green energy source around. Through the years, we have learned to tap other resources and these examples include wind power, geothermal energy, hydroelectricity and biogas. These are all safe and by using these more often, we don’t need to depend on oil which is a nonrenewable resource.

To make this happen, we have to persuade our law makers to promote the use of such resources. Although you hear speeches left and right about their concern for the environment, it is all talk and not that much action. It is something that has to change.

Two countries that have increased solar usage happen to be Germany and Japan. Spain, France, Italy and South Korea are next in the list and where is the United States? Well, one thing is for certain and that it is not in the top 10 despite the fact that it is an industrialized nation.

How to Make Your Own Green Energy Source

May 23rd, 2010

Wouldn’t it be great if we can produce our own green energy source? If we can do that, we don’t have to pay electrical bills or gasoline anymore for our cars. While we can buy some of the equipment, the rest will have to be done on our own.

Take solar or wind energy for example. We already know how to harness and make it. If you want to make one, do some research online and then set up the system yourself.

To have solar energy, you will need to buy an inverter, battery, charge controller, solar panels, some wires and support structure. The only difference with wind energy is that you need a fan. Once you have everything you need, you can put it all together.

If you are not skillful, you will be happy to know that some companies sell the entire system. By buying it from them and having it installed by their experts, you are sure that there won’t be any problems the moment you switch it on.

There is one more thing you need before you can use one or the two green energy sources. Before you buy the materials or the system, make sure you have a flat area that is about a hundred square feet or so because it occupies a lot of space.

For those who don’t have the space or the budget to use these two energy sources, another option is to create your own biofuels.

Biofuels are used in many countries and they get it from harvesting corn, sugar and other crops. Luckily, you don’t need a farm to produce it because you can also make your own using some recycled waste.

A good example of this is vegetable oil which we use for cooking. To turn this into a biofuel, we first filter it by warming up the liquid and then filtering this with a coffee filter. The next step is to remove the water also by boiling it again at 100 degrees for a short period of time.

We need to know the amount of lye present in the vegetable oil and we do this by a process known as titration. When we are done with that, we now mix sodium hydroxide to produce sodium methoxide.

The process of converting used vegetable oil before it becomes a biofuel takes quite awhile and it must be heated the entire time. This is done so the fuel we produce is pure and only when this is achieved that we give it time to cool.

Just how much biofuel we make after all the work varies but you will have an idea of how much you have produced since this is the one you see floating at the top. If there is still some glycerin present, filter it again. From there, you already have your own backyard biofuel which you can use and even sell to those who are just as concerned with the environment as you are.

By making our own green energy sources, we make ourselves less dependent on gasoline in its various forms to power our heater, home or car. Why don’t a lot of people do it? Well simply because they don’t have the time to make it and would rather rely on someone else to do it for them.

Benefits of Green Energy Sources

For a very long time, we have relied on fossil fuels. It provides heat to our homes, gas for our cars and electricity. Since we are now using it more than ever, there is a consequence. We are depleting our resources and slowly killing our planet. Fortunately, we can change our ways and then shift our attention to green energy sources.

But why green energy sources? Well because there are advantages to using them which we will never be able to get if we don’t change our ways. This is also even if some will argue that the problem with green energy is that it is sometimes difficult to generate the power we need. While that may be true, that is why there are other green energy sources available and we just to know which ones are viable given the geographic location.

The various green energy sources such as solar, wind, wave, hydropower and geothermal do not produce anything harmful which may have a negative effect on the environment. This is the exact opposite of what you get when you continue to operate a coal or nuclear power plant.

Coal you have to remember releases carbon dioxide into the air. On its own, it may not cause that much damage but there are currently 50,000 coal plants around the world and that number is expected to grow.

Nuclear plants may not release anything harmful into the air. The issue is how we dispose of the spend rods and if another nuclear accident should occur. We remember Chernobyl and Three Mile Island. We have probably learned better ways to prevent another incident from happening. Through the years, a few minor accidents have occurred and although the leak was contained, just imagine if it wasn’t?

Green energy sources may not be maintenance free but at least it does not require that much to maintain them compared to conventional means. In the end, we save money because such facilities don’t cost that much to operate.

The next advantage of using green energy sources is that we will never run out of them. For centuries, the sun’s rays have reached so has the wind which is blown from the sea. By using it, we decrease our dependence on oil which is a nonrenewable resource.

If you think about it, many of us have taken these green energy sources for granted. If we do the right thing now, future generations will not have to face the mess that we could have handled on our own years before.

In short, the power is in our hands. We have the technology and we know what to do with it. The only thing we need is to do is to put our money where our mouth is because despite the number of conferences on global warming and climate change, little has happened.

It is easy to talk about how concerned we are about the environment but you have to ask yourself when will more solar panels or wind turbines will be erected? When will the number of coal or nuclear power plants be reduced?

Green energy sources is the solution to the environmental, political and social problems of this lifetime. By spending more on these technologies, no country will have to depend on another or even a corporation for their power needs because they are self dependent and free.

Understanding The Beginning Stages Of Wind Energy

May 23rd, 2010

For several hundred years people have used wind for an energy source. From the windmills that can still be seen in Holland to the American farmlands, the wind has been utilized to help grind the grain or to pump water. Wind energy is not a new idea! It is just getting more attention today due to our energy crisis. Today there are wind turbines to change the wind’s energy into useable electricity.

Similar to windmills the wind turbine get attached to a tower, so it can capture the right amount of the wind’s energy. A good elevation for these turbines to be the most effective is about 100 feet or higher. This way they can draw energy from the fastest winds that are not as turbulent as they are on the surface.

These are almost like the propellers you see in airplanes. However, it all revolves around having 2 to 3 blades and attaching them to a rotor. When the pockets are caught up in the propellers, it allows the rotor to turn and start the generator. This in turn creates electricity for many of the areas that are hooked up to the source.

While most of the versions you see are large, they can also be used in smaller scales. Whether it’s just to pump water, or lower power bills, all the farmers, ranchers, and homeowners out there take advantage of them. If not, they should.

Now, if you need a larger application, then more than one turbine will need to be utilized. Normally these are just combined with solar power applications. You often see these as part of a utility grid power system or working together in a wind plant somewhere. While this may sound like a far way off, many power companies today are purchasing excess energy from their customers that use wind energy. So not only will they save money, but you will as well.

It’s safe to say that we are depleting the fossil fuels out there at an astonishing rate. This is why you need to find alternative power, which in this case is wind energy. If it’s not wind energy, then it’s solar energy. In fact, you can even use the two of them together for more savings in businesses and homes.

Wind energy is 100% renewable an causes no harm to the environment. This is the type of energy that you need to be using these days worldwide. You could ultimately save 100% on your energy costs, through using this power along with other forms of renewable energies. You will also being doing something good for your environment.

So look into getting a wind energy system setup for you home or business today. You will not be sorry that you did and for more information on this topic, there is plenty of information available through the Internet, local home building supply stores, and your local power company.

Something You Should Really Know Before You Begin To Develop A Wind Generator At Your Home

By: Gregory Gray

Wind generator is a device that used to gather the kinetic power from the wind and change it into a form of energy to run your place appliances. This strategy is widely use for most of the house owners who have the wish to cut down their household bills costs or absolutely living off grid.

How much the home energy you can generate for your house is heavily depending on your wind turbine quantity and your geographic location? If you are not living in areas with a lot of strong winds, then it is wise for you to totally scrap down your idea to use wind powers as your source of your home energy.

As for the quantity, you need to be realistic. You do not expect that your one wind turbine would help you utterly cut down your electrical charges by fifty percent or totally remove it. You have to take the account that wind is spasmodic and very unpredictable. The result of the wind power can be produced on each day are vary. Therefore keep it in your mind’s eye that counting on one wind turbine to gather all of the winds and convert it to run your whole house for each day is just mad. There’s a limit for one wind generator to produce the energy.

Just as the old people used to claimed, many hands make light work and quicker. Hence if you are serious about to cut back your utility costs, put more effort and build more of your wind generators. You may spend more than $200 or even more but the end justifies all since you going to save a lot of money in the long term.

Building a turbine doesn’t unscramble your home energy problem at once . You should aware that if you’re an enormous energy customer, you still have to pay more for your electricity charges. Don’t go nut to let your home appliances to run for whole days because you’ve got the wind turbine outside your house manufacturing electricity for you.
