The factory made wind mills can cost around three thousand dollars for just an entry level one. But you can make a wind mill of your own by just spending a little more than two hundred dollars. The things you should do in order to attain this includes making a plan and doing some home work. The things you should set up in order to make a wind mill are:

1) Generator blades: The finest materials to use in the making these blades are ABS or PVC pipes. They are strong but light, and are easily available.

2) Generator: We can make use of a simple DC motor with small RPM. A DC motor usually takes in electricity and in turn rotates its shaft. But when you are rotating the shaft in the opposite direction you can produce electricity.

3) Generator housing: We can make very efficient generator housing by using painted PVC pipe as the pipe will help protect the generator against the weather.

4) Tail vane: This is the part of the wind generator which is used to rotate the blades to make them face the wind. We can use any type of scrap material which suits the purpose to make this.

5) Tower: A few pipes can be easily used to make a stable and efficient tower for the wind generator.

All this can e done with ease and the main factor is that you will save two thousand eight hundred dollars by doing this.

At some point of time, you would have surely wondered as to how much do solar panels cost? Certainly the most obvious answer would be that they are quite expensive initially. A great deal of specialised material and engineering goes into the manufacturing of these solar panels. But there are a large number of companies today which sell at a lesser price.

The cost of the solar panel will greatly depend upon what are interested in getting. The cost of the solar panel will also depend upon to a great extent upon the watts of power that will be generated. The second thing that can make a difference in the price of the solar panel will be the material used for making the entire system.

But how much do the solar panel costs? Both the crystalline and amorphous silicon solar panels can cost approximately $5 per Watt and can go up to $10 to $15.

The concept of renewable energy has now come up when the conservation of resources have become such a global concern. Scientists have come up with different methods and strategies claming to save the non – renewable energy resources. However, since the pre historic times our ancestors have been using the renewable energy resources in many ways. Technically speaking, use of renewable energy resources an option has been explored and used long back. The pre historic people burned the bio mass for light and heat; the water mills and windmills were used for agricultural purposes way before we could understood the potential energy that water could provide.

The uses of non- renewable resources have created a problem throughout. The burning of such resources have always added to the problem of pollution and there by triggering the terror of global warning. It’s understandable that there are certain places where it’s just indispensable to give up the use of the non – renewable energy resources, leaving those the others could start using the renewable energy resources to save the environment. Not only saving the environment is crucial theses days, but the possibility of exhausting all the non- renewable resources is another concern. The renewable energy rescores are there and would be there. They have the capacity to be used over and over again without any kind of depletion which is not the case in the case of non renewable resources. For example, if you burn a piece of wood, it would turn into ashes. We can’t use ashes again as we could use wood- this is a non renewable resource. Another example -electricity is created by running water. Now the same water could be used over and over again. Electricity is not a component or ingredient making the water, that once electricity is extracted the water can’t be used again to produce electricity. However, on the other hand the non – renewable resources is the result of million of years of chemical reaction beneath the surface of the earth. This process is a very slow and natural process. This was never initiated by human beings now could it be initiated when we have exhausted all the natural resources. The urgency and the need of starting to use renewable energy resources are evident by this small fact. But still the companies are being a little reluctant to understand and implement the use of renewable energy resources over the non renewable resources.

There are so many environmentalist and social activist trying to make people and big companies understand the depletion that these non renewable energy resources are causing to the environment. Today we are looking at the non – renewable resources as a cheaper alternative as compared to the renewable energy resources, but this is only a micro view of the picture. They are not realizing today that our generations would be paying the cost for this carelessness. Not only that for the coming generations there would be either no or not enough non renewable resources left but would also be gifted with umpteen numbers of diseases. The environment would deplete in a way that no one could have imagined, giving birth to problems and diseases that the medical sciences would fail to cure.

Renewable energy as the name suggests is the energy that could be created by renewable resources. The resources that have a never ending supply on earth. Like the solar energy, the water current, the wind energy etc. Energies as such would always be there. They have always been in the past and not even an iota of it has been depleted. Making renewable energy with these resources is what the modern world is looking at. Currently the source of energy is the non renewable resource that comes after burning the fossil fuels. As we burn them we are not only exhausting the non- renewable resources but producing lots of carbon dioxide and gases that are dangerous and that pollute the environment.  This is primarily responsible for the global warming depleting the ozone layer. Thereby letting us exposed to the ultra violate radiation of the sun. In a scenario like this, making renewable energy not only becomes important but indispensable.

There are various kinds of renewable energy. We have the solar energy from the sun; wind energy from the movement of wind turbines; biomass energy; hydropower; burning waste and geothermal energy. Making renewable energy from any one or a combination of ant of them is what we are striving for.

Making renewable energy is important, it doesn’t matter which one you are using to create energy as long as it’s renewable. The best one to making renewable energy would depend upon the kind of life style the place has and the geographical area the place were the installation is intended to be has. As for example, the near the shore areas would prefer to making renewable energy by the use of windmills. Setting up such installations would also help provide new job opportunities.

If we consider the cost of making renewable energy as compared to the use of non –renewable resources – to start with it’s a little to the higher side. The reason it being on the higher side is that as if now we don’t have infrastructure that could support the renewable resources as we have for the non- renewable resources. Now when we strive to calculate the cost of burning the fossil fuels we are only considering the acquiring cost of them. What we forget to add is the cost that we would be paying once we use up all of them. We are not incorporating the cost of the damage that it’s doing to the environment by producing carbon dioxide and other harming gases. We are neglecting the cost of the global warming that it’s increasing for us and the depletion of ozone layer. It’s not even possible to add that cost to the acquisition cost of the non-renewable resources, as all of them are simply price less. Now, if we add all that cost we would see that making renewable energy is relatively an inexpensive proposition.
That would not only save the non – renewable resources from getting exhausted but would also help creating a better environment for our coming generations.
