How Does Wind Energy Work? - Facts About Wind Energy

Image via Wikipedia

How does wind energy work? In this article, I will give a simplified explanation of how the turbine turns the wind energy into electricity. I will also briefly explain the structure of a wind turbine.
How Wind Turbines Generate Electricity

1. Wind blows onto the turbine's blades, causing them to rotate.
2. The turbine's blades rotate a shaft inside the box situated at the top (where all the blades converge).
3. This shaft is connected to a gearbox. This increases the speed of the rotation.
4. Magnetic fields in the generator use the increased speed from the gearbox to transform the rotational energy into electricity.
5. This electricity then gets fed to a transformer. This converts the electricity from the generator from about 700 volts to the level of voltage needed for distribution (usually 33,000 volts).
6. This electricity is then transmitted around the country via the National Grid.

Structure of a Wind Turbine
On top of the nacelle (the box at the top at the turbine), there are instruments that measure the speed and direction of the wind. Whenever the wind direction changes, the nacelle is turned by direction motors so that the blades can face into the wind. There are also brakes fitted into the nacelle so that if there is a storm the turbine can be turned off. This is an importance feature because otherwise the turbine may become damaged in severe weather conditions.
Computers record all this information and transmit it all to a control centre. This means that engineers don't need to visit the turbine too often. But they still need to visit occasionally to carry out mechanical checks.

Have you ever thought about having your own wind turbine? Most people pay far too much for their electricity, and the truth is, generating your own power is much easier than most people realize. Don't be one of the many people who spend too much on their energy bills.

A Guide To Using Solar Energy To Produce Power

Image via Wikipedia

Did you know that solar power is a renewable, clean and cheap source of energy?
Are you frustrated with understanding the how and why associated with alternative enegry fuels? Once the mystique is removed from the idea of using solar energy to produce power people will began to understand how it all works. This will lead to people seeing how using solar energy can be looked at as a viable alternative source of energy. In fact in this choice of alternative energy the largest component is the sun. Scientist and those in the private sector are even now looking for ways to make using solar energy to produce power in homes and businesses more economically feasible
HOW DOES IT WORK?
When considering the choice of using solar energy to produce power you should understand how it works right? Well if you can imagine that it works much the same way that leaving your garden hose laying in the sun all day on a hot sunny day. When you go to use it the first thing that comes out is hot water having been heated by the sun all day.
This is a simplified version of one way to utilize solar energy. There is usually a water container that collects the sun's rays in the form of heat. After this is heated to a pre-determined temperature it is then properly utilized elsewhere.
Some common applications of this have been to heat water in swimming pools and ponds with water moved into large containers that are basked in the sun all day. The mechanism will then move the water back into the pool or pond once the water reaches a preset temperature which in turn helps heat the rest of the water. This of course has been utilized in more commercial applications as well.
DID YOU KNOW?
Approximately more than ten thousand homes in the United States are entirely powered by solar energy.
Another way that is properly thought of when considering using solar energy to produce power gathering solar power through photovoltaic cells that in turn convert energy obtained from the sun DIRECTLY into electricity. This electricity produced is in Direct Current or (DC) format. This (DC) can then be stored directly into storage batteries. After this (DC) is converted to Alternating Current (AC) it can be used to operate lights and any other common appliance.
INTERESTING FACT:
Silicon from just one ton of sand used in photovoltaic cells could produce as much electricity as burning five hundred thousand tons of coal.
CONCLUSION
Your goal? To start utilizing these alternative fuels whenever and wherever possible. However, there are areas that have a lot more average days of sunshine, like the southwestern part of the United States, where using solar energy to produce power can be a good source of power. When you couple this with the fact that you are dealing with solar power which is clean, cheap and renewable it just makes sense. However, with a proper understanding how it works , you can see how using solar energy may not be a good solution in areas of the country with several days of overcast skies and insufficient sunlight.

Different Principals of Solar Energy

Image by bsterling via Flickr

One of the most successful energy technologies used today is solar energy created by photovoltaic solar-cells. PV-based solar energy is what most people refer to when discussing solar power mainly because it is the most commonly marketed. While there are two separate operable solar cell types, photovoltaic and thin-film solar cells, the thin film choice is far less efficient and is not used as often.
PV solar cells take the direct approach by converting sunshine into electricity without any detours. Crystalline silicon solar cells create different types of reactions from the sun's rays Either reflected, being absorbed or passing through without any commitment, only the absorbed photons from the sun count. Only 20% of the available source is ever captured, the same place it was ten years ago. In comparison, a fossil fuel generator converts at 28%. The record held by the National Renewable Energy Laboratory is 40.8% in August 2008. Performance is at the mercy of climate and environmental conditions.
Progressing to the point where a larger percentage of solar energy is captured and turned into energy is the direction that many of our scientists are moving in.
Concentrating solar power (CSP) is a term that many may not yet be familiar with. Using an optical lens, the sun's heat is amplified, high temperatures are reached and water is turned into steam that can be used to power a turbine and generate electricity.
Concentrating solar power may be one of the best ideas yet and has already been tried out on a large commercial scale. The overall principal of CSP has more variables than the PV-based solar system because the power generated can be stored to meet spikes in demand and can be used in relation to other types of fuels because of the ability to share the steam turbines. There are two other different kinds of CSPs now being tested and monitored for use in large utility operations, parabolic-trough systems and dish-shaped receivers.
5-10 acres of land are demanded for each megawatt of electric capacity in the parabolic-trough system that draws the sun's energy through long curved mirrors. As the mirrors tilt toward the sun, attached pipes carry the boiling oil to water in a conventional steam generator. But these cannot be built everywhere. Flat, dry areas work best for this solar type concept.
The dish system resembles a large TV satellite dish and tracks the sun the same way a dish will track a TV signal to a receiver. But instead of finding a signal, this dish converts heat into mechanical energy, turning a turbine. Right now there is an experimental dish set up in New Mexico that is rating the amount of energy provided.
New ideas and scientific principals are being discovered and tested every day that use the resource of the sun as a base. Practical solutions together with existing methods will continue to advance our goal of independent energy means, hopefully sooner than later.

Permanent Magnetic Generator - Free Energy For Life

Permanent Magnetic Generators
A permanent magnetic generator is actually a very simple piece of technology, it is a lot like your standard generator except it runs off of magnets rather than gasoline. This makes it a very cheap and eco friendly source of electricity. Also because magnets are the power source it has the ability to run for years without stopping or the need of any additional help, this is why thousands of people have been hooking them up to their homes.
People from all over have started using these generators as a source of electricity for their houses, people that have done this report a savings between 50%-100% on their energy bills every month.
Science Behind Them
Every generator is trying to do one thing and that is turn its turbine, when the turbine spins electricity is made, a standard generator does this by burning gasoline, a water wheel would use the flow of a stream to turn a turbine and a magnetic generator uses magnets that are placed on and around the turbine, they are placed in such a way that one side is constantly being pushed down and the other is being pulled up creating a constant spinning of the turbine, this will allow it to run for years without ever stopping.
How can I get my own Generator?
There are some being built and sold to the public but they are very hard to get and run for about 700 dollars, this is why I recommend to most people that they just get a guide that will show them how to build one themselves, Guides are a great option because they contain pictures as well as step by step instructions that are very simple to follow, even people that have no experience working with their hands are building these without trouble. A home-built generator usually costs between 60-90 dollars to make.

Wind and Solar Power As Sources of Electricity

It is a well known fact that wind and solar power are alternatives means of energy. People understand that these two forms of energies can be utilized in generating electricity that will power our homes. Before, people only acknowledge the fact that the sun is just the alternative means but nowadays, people recognize that wind too can provide and can be a source of energy. This is why a number of households resort to both wind and solar power as options to the electricity which they get from utility companies.
 
With the continuous advancement in technology also comes the availability and accessibility of wind and solar power to be utilized in powering homes and households. The methods or ways on how these energies can be generated as well have improved and developed a lot that it makes the process of wind and solar power generation reliable.
 
Wind and Solar power comes with its advantages and disadvantages. However, there are more reasons to actually resort to this forms of renewable energy than not to get them at all. Some of the disadvantages include the fact that solar cells or panels can be quite costly and that wind and solar power can't be stable when the source of energy is not there - meaning if the sun is not shining or if the wind is not blowing.
 
The advantageous are truly beneficial. One good advantage is the fact that this type of energy is unlimited meaning the sun will always shine every day just the same as the wind will continue to blow. Thus, source will always be available and it will not deplete. Another good reason to resort to wind and solar power is the fact that it does not harm the environment. These forms of energy do not cause any pollution and thus are means of energy which are environmental friendly and help preserve the planet. Wind turbines are very inexpensive and simple to build and solar panels do not require much maintenance. A good thing too is that excess power that you are able to store can then be sold to suppliers of electricity.
 
As you can see, the benefits that come with wind and solar power truly outweigh the disadvantages. What it ultimately means to you is that you no longer will have to do with monthly bills on electricity with is very costly. This translates to hundreds of dollars worth of savings in months and thousands in a year.

How to Build a Solar Powered Water Heater - Cheap, Easy, and Green

Have you ever left a bottle of water in the sun or in the car and when you go to drink it it's disgustingly warm? Well imagine if you had left that water in a black water bottle, think that the water in it would be hotter? Of course!
Learning how to build a solar powered water heater is not hard, in fact it is about 90% common sense and 10% good directions. And a quick note that solar powered water heaters work better in warmer conditions and climates so either in the summer or year round in some of the warmer states and countries in this world. But it won't work too well in really cold conditions..duh.
With that out of the way let's go over the basic things we will need to build a solar powered water heater. First we will need black PVC piping. This is where the water will be heated before being stored in the hot water tank. Secondly, if you hadn't guessed we will need a place to store the newly created hot water. I would say that anybody reading this will already have a water tank in their house so there is no need to buy anything more, we will use what we have.
You are also going to need insulating material to insulate the pipes that carry the hot water from the solar powered water heater to the hot water tank. And lastly we will need a light source..any takers??? The SUN perhaps? Ok so the materials can all be purchased at a local hardware store for pretty well less than $100 dollars, give or take a few bucks. I don't know what you all pay for your monthly hot water bill but mine used to be around $40-$50 bucks depending on the month.
Nowadays I pay max $10, I have paid off my solar powered water heater so many times it ain't funny, and it keeps on producing more for me everyday. Is a solar powered water heater perfect? Well pretty darn near, obviously it won't make your water boil, but it gets it dang hot and who wants to have a shower in scalding water anyways?

If you are keen to learn more about building your own make a solar powered water heater and making a difference to the environment then you oughta check out this website at http://www.squidoo.com/solarpoweredwaterheater. It has a lot of good information and teaches you to make a renewable energy source yourself. Feel good about doing your part for the environment and providing your house with free energy.

Cheap Solar Panels For Your Home Energy

Solar energy is the wave of the future in energy procurement: solar is free, easy to obtain, and provides more than enough energy for most typical households. For these very reasons, building your own cheap solar panels is a great way to reduce utility costs and "Go Green" at the same time!
Why Go Solar?
Solar panels, also known as photovoltaic cells capture the energy from sunlight and store it in a battery bank. You then run your appliances and other electrical items from the battery bank. In essence, this completely erases the carbon footprint of your home for electricity costs. Solar energy is renewable, easy to obtain, and very cheap to capture once your system is set up. Building cheap solar panels is a great way to further reduce the cost of implementing a solar system. Initial installation for pre-manufactured solar power systems ranges from $10,000-16,000 per home and can be quite expensive. Building your own cheap solar panels from readily available materials not only helps you capitalize on a renewable energy source, but also cuts down even further on your impact on the environment as your panels will not have required any manufacturing processes.
Its Easy!
Numerous kits are available for download from various vendors that teach you how to make cheap solar panels at home with materials commonly found in your local hardware store. The information that you will download contains instructions on calculating your actual electricity needs based on your current utility bills. Once you have that information, you can then begin building the cheap solar panels, each of which should take you about a day to construct. Once you have your battery bank and a few of the solar panels built, you can begin switching your power reliance away from the electric company a bit at a time until finally you are able to live completely "off-grid." Most municipalities will require a site inspection to make sure your solar power system is up to code, but after that you should be free to use your new solar power home exclusively.
Save Money!
Your new solar power home will pay for itself many times over in the course of its useful life. Many utility companies will even allow a resident connection to the grid and can pull some of your excess energy units from the cheap solar panels you built, netting you a small energy credit or even a bit of a profit from your solar installation. The kit or download that you obtain to build the cheap solar panels will include instructions on not only construction, but on how best to capitalize on your solar investment. There are a variety of tax credits and cash incentives available to consumers who are now interested in building or retrofitting a solar power home, and the building kit or how to video on building a solar power home should explain how best to utilize these incentives.
Solar energy is a great alternative to paying a large utility conglomerate each month. Use the information readily available from a variety of sources to capture and utilize your own energy and make a difference for our planet today!
