DIY Windmills - An Alternate Source Of Energy
November 12, 2009 by Go Green Tips · Leave a Comment
It’s not a secret that there are various energy source elements out there today. To the best of our knowledge and this aspect is of fundamental importance for us that this is so because people who are looking for an alternate source of energy are growing.
As far as my personal experience can be taken into account, there are now many options for the placing of an alternate source of energy. And, in short, what is more important that among the other this includes hydro, solar, and windmills. Beyond any doubt you have to pay serious attention to the fact that the only problem is that, the initial cost of constructing your own power generator is rather high. But, if we are making a closer investigation of this problem, with the constant rise in price of products producing energy, there is now, as a matter of fact, a growing feeling to make one’s own energy source. And it is obvious that when you take a closer look at this issue you would notice that while there are many alternate sources of energy out there, the most advisable would be, without any doubt, homemade windmills. What matters here is that as a matter of fact, you may know that solar and hydro energy sources are also desirable but these particular energy sources need specialized equipments so that they can be built.
In this wise, the other thing that needs to be added is that the price in its construction might be staggering taking into consideration not just the specialized parts thereof but also your precious time and energy not to mention the money that you will be spending in the construction of said energy sources.
On the other hand, as it may be observed we can safely assume that windmills might be constructed without the price required in putting up that solar or hydro energy source. So, in addition it should be also mentioned that it is no great surprise that if you’re constructing that energy source for economical reasons, then homemade windmills is the energy source for you.
Moreover, this problem has to do with the fact that while still shelling out some money, it is nevertheless low-priced than that required of other sources of energy. And, according to my personal experience, while having your own windmill is great, it nevertheless has some disadvantages to it. An example is that, we have every reason to believe that it requires a larger area compared to other sources of energy. But, in conclusion, it’s important to keep in mind that with the ever growing need of alternate energy, having your own might prove advantageous for you. So, don’t be afraid, go ahead and make that windmill.

Dams - A Source Of Sustainable Power
November 5, 2009 by Go Green Tips · Leave a Comment
Dams have been around for a century now. Beavers used it, although not for energy and now humans employ it as source for that ingredient in survival: power.
Hydroelectricity
Hydropower generates hydroelectricity. It produces power with the help of gravity. It is the most common alternate source of energy. After the dam (called the hydroelectric complex) is built the complex it produces no waste whatsoever. Hydroelectric power comes from waters potential energy.
Imagine a glass bubble, and you’re in it. When the walls crack water exerts pressure on that one whole until water comes through that tiny gap. It’s the same thing with a dam. The engineers collect the dam’s power by harnessing it with the use of a turbine which then connected to a generator. In this matter the power extracted from the rushing water depends on the amount of force the water exerts on the turbine and on the difference of the water’s average gravitational pull. The difference between the height and the outflow is called the head
The amount of the water’s potential energy depends on how high the dam is from its outflow. Dams help cities by supplying energy during extremely high demand times and during off peak the turbines pump water into higher reservoirs so that when electricity consumption is high again.
Where Is The Power Supplied
Most hydroelectric power plants supply public entities; there are some which are funded by industrial companies for their specific use. Such industries like aluminum electrolytic plants build there own hydroelectric power plants due to their high energy consumption. In fact the world’s largest dam the Coulee Dam, located in Bellingham Washington was switched to support Alcoa Aluminum plant, which at the time was the largest supplier of materials for war planes; afterwards though it was used for public electricity and as a source for irrigation.
There are also small scale hydroelectric power plants, most of them are located in north America. A plant is classified as small scale when it only produces 10- 30 megawatts. These power sources are usually connected to power grids to supply energy to small isolated communities or even to a single family home. In China small hydro schemes are very popular due to a high number of factories wishing to have their own supply of electricity.
Other Common Water Energy Sources
Other common hydro resources are rivers, the ocean, waterfalls and even ponds or lakes. Rivers power plants where in no reservoir can be built are called run-of-the-river-, while the ocean is put into good use because of the tides. A tidal power plant harnesses the energy of the coming and the going of the tides. Uncommon but never the less employed are kinetic energy water plants.
Why It Makes Sense
Economically the use of hydropower is cost effective because our primary source the fossil fuel is expensive and slowly getting used up. Water is of the abundance and most of the time it is free. Granted that dams and other hydroelectric power plants are quite expensive to build, but the pros far out weigh the cons. The operating and maintenance cost of a hydroplant is considerably cheaper than looking for fossil fuel, drilling for it, and refining it to become oil. What’s more a hydroelectric power plant cannot be affected and is not subject to the rise and fall of fuel prices.

Life Without Sustainable Power

What happens when the oil prices and production costs get too high? What if our fossil fuel supply runs out? What will happen then? Actually, to fully appreciate sustainable power, these aren’t the only questions we should ask. Perhaps we should inquire: Where does 20% of our electricity supply come from? How are far off towns furnished with power? You see sustainable energy is not just for the future, it is here, it is now.
The Real Deal
The thing about sustainable energy is that it arouses debates from politicians, NGO’s, advocates and opponents all have certain grounds for saying that sustainable works or is a bad thing after all. Perhaps we should begin by defining what sustainable power is. When we say sustain it means to support, uphold, to keep from falling. So when we say sustainable power it means energy with unending resources. In the case of today sustainable energy means endless resources fro power supply without the harmful effects on the environment.
Its Not Sustainable It’s the Alternate
In all reality it is not sustainable energy that precipitates the conflict. It is the “alternate source” of energy that is the root of all things that create conflict. A lot of people argue that alternate energy resources are simply too new a resource fuelled by technology for it to be really said that it is indeed safe.
What is more, some authorized people on the matter of energy say that alternate energy resources are simply not powerful enough to cope with the demands of the world. No matter which way we argue alternate energy resources are part of sustainable power and sustainable power means we live the humans live on as a species; were not supposed to die or else it is useless for use to look for ways to improve ourselves. After all isn’t future the reason for our continued quest to be better and more environmentally aware?
Its Here, There, Everywhere
Alternate energy resources derived naturally have been employed as early as the time of the pharaohs. Today alternate energy resources are scattered all around the world. From the richest countries to the third world nations. In northwester Europe wind farms are abundant. The Philippines, New Zealand, Kenya, Iceland, Germany, Canada, Turkey, Mexico, and even the states make use of geothermal plants to supply a portion of their electricity. Hydropower so popular in the US and in china are used to generate enough electricity to power small towns and help power the enormous electrical consumption of a city like Las Vegas.
Its Now and It Can’t Be Denied
If you think that earth is already polluted and in peril, then imagine what if thousands of years ago our ancestors all used fossil fuels and burned coals for every energy need they have? History says that with every development and discovery man makes, the earth gets polluted every day. So there must have been that one thing that slowed it down a bit.
Remember the great smog of London where over 8,000 people died? Well that happened because they were experiencing unusually cold weather so they in turn consumed and lit up more coals, thereby fogging the air with smog. If alternate energy resources were never used we wouldn’t even be here today. So be thankful and be a supporter not only in words but in action as well.
