Homemade Solar Panels – 3 Reasons Why You Need Them
Our planet is currently experiencing a global deficiency of natural resources and is rapidly headed for a major meltdown. It is not like it used to be, where we had a limitless supply of resources to tap into and use as we pleased. We were extremely wasteful and failed to take care of that which was placed in our charge. Now through our own faults, we must come up with ways to safeguard what is left, as well as alternatives to their use.
Solar energy represents one of these successful means by which we can withdraw from the demands set forth on our natural resources. This brings us to reason number one for needing solar panels – to preserve what is left of our natural resources.
Along with this, we can also boast our eco plans greatly and make our planet a greener place to reside. By the use of solar panels, we drastically cut the harmful emissions generation that is destroying our ozone layer. With appropriate management, we could commit to heal this layer for our grandchildren’s benefit.
The third major reason for escalating the use of solar panels is due to our poor economy. We are presently in a downward trend and our economic recovery does not look great at this time. By using solar panels whenever we can, there is a likely prospect that we will save a substantial sum of money that could be used for other purposes.
As you can see, there really are several very good reasons that one would want to employ the use of solar energy over our current conventional means. So, why not take action and make you own solar panels?

Things You Need To Know To Build Your Own Wind Turbine
When it comes to ecological matters, there are many options to power your home with environmental friendly energy resources. One of them is the power that you can obtain from the wind. However, these ecological gadgets may be a little expensive and too large for domestic use. That is why homemade wind turbines are becoming more and more popular these days. Plenty of easy-to-build wind turbines systems are available on the market. Besides, they are quite affordable, as you only need to purchase the blades and the shaft. For less than $150 and a little time and effort you are ready to build your own wind turbine and reduce your impact on the earth’s ecosystems.
Before starting to build your own wind turbine, you need to become familiar with the components of a wind turbine. Three mains parts are necessary to get this windmill to work: Rotor blades, a shaft and a generator or a transformer. Rotor blades are usually made of plastic or wood, and the most expensive can be made of aluminum. They are intended to be very lightweight, so the wind can stir them easily. The rotation of these blades is quite important because more movement leads to more rotational energy and more power to be used. A rotor holds the blades and absorbs the rotation dynamics generated by the blades. This rotor is attached to the wind turbine shaft, so they can spin together and power can be transferred to the generator. An electric generator or transformed is required when you build your own wind turbine. As power is directed through the shaft, the generator captures it and turns it into electricity. Some wind turbine systems provide batteries to save extra power. Electrical wires feed into a battery, where the energy can be stored. This way you can supply your home with renewable resource energy anytime and reduce you impact on the environment.
It is strongly recommended that you check the wind patterns in your area with a little online research before installing your wind turbine. You should be able to determine the average strength and speed of the winds that blows over your place.
It should be placed in order get a considerable amount of wind, so it can work properly. The blades should be facing the right direction, so they can take as many winds as possible. You should take into account that 45 degrees or more will stop any possibility of power generation.
To get to build your own wind turbine will mean a reduction in your ecological footprint. It will also save you a lot of money, as you will not buy a commercial turbine and will do it yourself. Besides, the electric power company bill will be highly reduced, as many of your home appliances will be supplied by your homemade turbine. You can have major savings in your domestic budget and a environmentally friendly house with your small scale homemade wind turbine.

Everything you need to know if you are planning to have a residential wind turbine
Lately, advertisements about residential wind turbines, articles about advantages of wind energy, government grants announced for utilising wind energy, opponents of wind turbines, and many more things are flowing into our minds increasingly day by day. Whether you have some basic knowledge about it or you know nothing about it, in this article you will have the chance to know about key facts about wind energy.
We will start from very basics and proceed to more detailed information about wind energy, particularly residential use of wind energy.
What is a wind turbine? How does it work?
A wind turbine is a machine that converts the energy in the wind to electrical energy by means of rotating blades and a generator. Of course the working principles of a wind turbine are much more complicated. They include transmission elements, safety units, controllers etc. The blades rotate by the blowing wind and the rotation is transferred to the generator within the turbine. And this generator is the source of electricity. Then from the generator depending on the configuration of the turbine electricity is fed to the grid or directly to the point of use.
What is the difference between a commercial and a residential wind turbine?
Just their capacities! While a commercial wind turbine can have a capacity of up to 5MW residential wind turbines are generally much smaller, i.e. a few hundred kilowatts maximum.
Why do people consider purchasing them? Isn’t buying electricity from the grid cheaper?
Actually, at the beginning yes. When the investment costs of a wind turbine is considered and reflected over years, for the first couple of years buying the electricity from the grid can be cheaper. However, the aim of using residential wind turbines is not only cheaper electricity. First of all they can be used at places where there is no grid connection. For example, farm houses far from grid connection or special small electrical appliances located in places where no grid exists can make use of small wind turbines for their electricity needs. In addition to these, wind turbines generate “clean energy”. This means that for generating electricity by wind turbines you don’t cause carbon dioxide emission like in many generation processes. Furthermore, in Ireland use of wind turbines for residential needs is also supported by the government and there are grants available for the initial investment. As a final remark, having a wind turbine for part of electricity needs of your house will result in a better Building Energy Rating (BER) report which will eventually increase the market value of your house.
Can wind turbines be used for any house?
No. First of all you have to make sure that there are not much obstacles (other houses, high towers etc.) that block the wind of the turbine. Second, you need to learn how windy your area is. For commercial installations generally measurements are made 6 months-1 year in advance of installation at the exact turbine location but for a small scale turbine you can use the wind statistics published generally by the government offices. Be sure to choose the measurement location closest to your area. For relatively less needs, such as a single appliance, roof-top wind turbines can be also used. Prior to installing a turbine always take the necessary permits that are required in your area.
What if a turbine generates more electricity than required?
Residential wind turbines can be either standalone systems or grid connected systems. If you have enough space to build a larger wind turbine then you can have it grid connected and you can get paid for the electricity you supply to the national grid.
How much can someone save with a residential wind turbine?
Actually, this all depends on your consumption and the capacity of your wind turbine as well as the wind conditions in your site. To give a rough estimation; some studies show that you can decrease your electricity bills up to 80 percent with a residential wind turbine of appropriate size.
What about maintenance of turbines?
Many small wind turbines have a small number of moving parts which make them suitable to use without maintenance for a long time. A wind turbine is expected to have an economic life of 20 years.
Where can I get detailed consultancy about residential wind turbines?
Windturbines is the largest retailer of micro turbines in Ireland, selling and installing over 100 turbines nationwide in 2008. You can visit their website or contact them to get more information about their products and your needs.
