Solar Cells: The Way Of America’s Energy Security
September 2, 2010 | Leave a Comment
The sun has had an impact on humankind since its beginning. The sun has had a significant influence in Greek mythology as well as religions. The English Druids, Buddhists, Hindus, Incas and Aztecs, and many native American tribes are just a sampling of the many peoples who held the sun and its solar energy, in high regard in their religious beliefs.
The prominence of the sun is due to its nearness to our planet. Actually a star, the suns closeness to us, allows for brilliance of the light and the intense heat that can be transferred into energy. One minute sampling of the suns heating ability would be the drying of our clothes. Plant life also relies on the suns light for its growth and food production. Food that is uneaten decays and over a tremendously long period of time becomes fossil fuel. These fuels known as oil, coal, and gas are then produced. Even the production of nuclear energy becomes possible when exploding stars called nova’s release uranium atoms.
The uses for the suns energy are infinite. Humankind has long made use of its properties. The 1890’s found people heating their hot water with solar energy. Cheaper than wood and coal, it was also a cleaner alternative. In the U. S. The states having the sunniest and warmest number of days emerged as the first ones to use solar energy for heating water. Solar panels to heat water were installed in thousands of homes by the 1920’s. When greater amounts of oil and gas were found and prices plummeted for these fuels, many reverted back to their use. Presently, there is concern that the demand is beginning to exceed the supply and solar energy has moved again to the forefront.
Experimental power plants continue to focus on the production of electricity, while others have found ways to produce it. The state of California is presently using the Mojave Desert to collect solar energy using parabolic troughs or ’solar mirrors.’ The special curve of the mirrors directs the energy to a pipe that can intensify the heat to cause water to boil. The boiling water causes steam and that steam will turn a turbine and make electricity.
A way has also been discovered to turn solar energy directly into electricity. This is accomplished by the use of photovoltaic cells. When struck by the sun, the PV’s or solar cells, cause the loosening of electrons. The loosened electrons move to the front of the panel creating an imbalance within the front and back surfaces. Acting as a connector, these surfaces allow the flow of electricity from positive to negative. Special devices located on these panels allow for the tracking of the suns rays and sunlight can be collected for longer periods.
This direct form of energy, from solar cell to electricity, is immediately available for use. In our homes, it can tun on our lights and run our appliances. Businesses can even store electricity in batteries for use in illuminating billboards during hours of darkness. Roadside emergency cell phones can also be ran with an energy stored battery.
There is still much to be discovered with the ongoing research of solar technologists. One of the latest frontiers is the electric powered automobile. The capability of PV cells in turning the suns energy directly into electricity will enable the motor s use of the electricity to keep it running smoothly, efficiently, and cleanly. The pollution created by older methods of power will disappear with the use of the suns energy. Technology that at one time was located miles above the Earth is now literally at our fingertips.
Harnessing the power of wind is now being used for the purpose of making electricity. Windy conditions are ideal for placement of wind turbines. Home Wind Generators The power of the wind has worked for mankind for many centuries.
Wind Power Will Bring Energy Liberty For North America
August 30, 2010 | Leave a Comment
Wind energy holds the key to the production of electricity. A winters gust of air or the warm gentle breezes of summer are all contributors to making wind energy a reality. It is not inconceivable to predict entire cities lit up using wind alone.
The benefits of wind power have been known to man for centuries. Sail boating would be impossible without the strength of the wind in her sails to propel here forward in the water. Farmers of old would make use of a single windmill to bring forth water from beneath the ground to aid in his crop growth. Wheat was once ground into flour as the wind alone would propel a large grindstone.
In present days, the wind is being used for an important purpose and that is in the production of electricity. Have you ever taken note of how the wind will make a pinwheel turn? The same premise is used in the propulsion of a device named a wind turbine. A turbine has enormous blades that are turned on a hub by the winds energy. The hub is attached to a shaft that turns and in doing so it enters a gear transmission box that increases the speed of the turning. Electricity is produced by this transmissions attachment to a high speed shaft that causes a generator to turn. In high wind conditions, the turbine has an installed brake that is used to prevent damage that could be cause by the blades moving too fast.
Controversy abounds with this modern day technology. The lack of knowledge on the part of the public has been the cause of many unconfirmed fears. Even the whirring sound made by the blades as they rotate has made for demonstrative outcry’s. Still, it is not at all unusual to see small single turbines located on properties for personal home use. Though a good idea for many, it is impractical for most, so wind farms containing thousand of turbines have been implemented and are beginning to take their place in today’s society.
Windy conditions are ideal for placement of wind turbines. The more wind there is, the more electricity can be made. One turbine has the minimum capacity to produce a 100 watts, or one kilowatt of power. This is enough to light ten 100 watt bulbs. When production is increased to 300 kilowatts, three thousand bulbs will glow. Using that as a base of multiplication for the number of turbines producing electricity now and the end result borders on staggering.
By 1999, California was home to over 11,000 turbines. Three large wind farms are located in places such as Palm Springs, Altamont Pass, and San Gorgonio Pass. The amount of power produced here is enough to illuminate the entire city of San Francisco giving California the honor of producing the most electrical power. Denmark and Germany have joined us in the use of wind turbines to produce electric power.
The distribution of this amassed power is carried out with the use of transformers. Electricity can be sent to far away sites through power lines. The arguments in regard to turbine use of wind energy continues today. Regardless of this controversy, more and more of these turbines can be seen as we travel though the countryside. An immense amount of progress has been made with the provision of electric power.
The more wind there is, the more electricity can be made. Global Wind Patterns Windy conditions are ideal for placement of wind turbines. The future of electricity is in wind power.
Use Solar Energy For Lighting Your Business

It was actually the use of a conventional approach or the use of batteries that electricity can be generated. With the advent of modern technology, solar energy can now be harnessed and channeled into useful purposes by mankind.
This form of energy is so important that it affects everything here on earth. Our plants for instance use this form of energy to create their own food through a process called photosynthesis. They have the ability to trap the chemical or radiant energy of the sun to produce water and carbon (iv) oxide which is the end product of the reaction undergone by the plants and which is also what we call, again, photosynthesis.
This form of power has been used since ancient time by human with a wide range of ever evolving technologies. The heat emanated or generated by solar power and with some secondary power resources such as wind and wave power, electricity made with water called hydroelectricity and biomass really account for most of the available renewable energy here on earth. It is only a small fraction of this source of power that is being utilized.
Some of the applications to which this form of energy can be used for include: space heating and cooling through the use of solar architecture, suitable or portable water via the process of distillation and disinfection, day lighting, solar hot water, solar cooking and also a high temperature process of heat for industrial use. To actually utilize this form of energy effectively, solar panel are built to bring this process into action.
Solar power is on the rise of becoming more and more popular than it has ever been in the past years.
Yes we can actually generate some forms of energy and harness them into useful purposes. So, the energy generated from the sun has some of advantages and disadvantages which are as follows:
The advantages of this form of energy are that it is free to produce and that it does not require fuel and does not produce waste in the form of pollution. Also, where the sun can be collected continuously, it can be used to generate electricity from the heat that is produced from the sun. It also finds its use in solar power garden light and battery chargers or for helping in paying home energy bills.
One of the disadvantages of this form of energy is that it does not work at night. It is very expensive to actually built solar panels or stations but it is coming down due to improvement on solar technology. Also, it can be unreliable unless you are located in a sunny climate. But notwithstanding, solar energy has gone so far to actually bring an end to light failure that most countries normally invest in this form of energy.

Build Your Own Affordable, Cheap Solar Panels
August 16, 2010 | Leave a Comment
Solar energy is without a doubt today’s number one alternative energy choice. It is no wonder then that one of the most searched for terms on the internet is cheap solar panels.
With the environmental disaster we are seeing unfold off the gulf of Mexico (The BP oil spill) more and more as a society we are finding our consciousness pricked into looking for cleaner and greener ways to help the environment.
For most people the idea of having their own solar system is indeed desirable, but there has always been the major stumbling block of the enormous cost of the solar panels.
Having a solar system installed can cost many thousands of dollars, money that many households simply do not have to spare, no matter how much they stand to save in the long run or how much they want to help the reduce their carbon footprints.
This alternative comes in the form of a DIY (do it yourself) kit. Now I’m sure some of you just tuned out at the thought of building your own solar panels, sounds complicated doesn’t it? Well surprisingly it isn’t, in fact it’s all most child play.
The kits come in the form of an easy to follow video series and instruction manual which you can downloaded in a matter of seconds online
All the materials you need to build your own panels are available from most hardware stores (tip: save even more money by sourcing the parts from your local salvage or junkyard). Armed with the most basic handyman skills, you can assemble your panels in just a couple of days (I recommend freeing up a weekend to give yourself ample time).
It’s a great project to get your children in on, provides them with an alternative to playing computer games all day, gives them a lesson in environmental issues and energy conservation. You won’t believe the buzz they will get when they realize the solar panel they built is powering a laptop etc.
Not only will you stand to save a lot of cash by building your own cheap solar panels as opposed to purchasing them pre built, you will also cut (depending on the number of panels you build and your homes energy needs) anywhere up to 80% (in some cases above this) off your traditional power usage, this can translate to hundreds of dollars saved on every power bill.
So whether you are looking to help reduce your carbon footprint or simply want to save a few dollars, take a look at the following link for side by side reviews of the leading Solar Power Kits and build your own solar panels today.
3 Reasons You Might Want To Avoid Certain Makes Of Wood Pellet Stoves
August 13, 2010 | Leave a Comment
What could make you want to avoid certain makes of wood pellet stoves ? There are a lot of positive things in favour of that idea, few against. The usual reason for NOT seriously considering is inertia. At times it is a lack of good information. Other times it’s fear of the unknown. Sometimes it’s because they don’t know exactly how to. Still other times ignorance of the possible benefits holds people back.
The key here is knowing enough about it. That’s logical. So let’s get more info. Let’s look at the three most important reasons that influenced others to avoid certain makes of wood pellet stoves.
First, poor quality parts. Yes, I hear your objections that some pellet stoves are made from low quality parts. For example the auger feed system on the pellets needs to be heavy duty. Poor quality parts can burn out or even bend and buckle. I concede your point, but not all wood pellet stoves are build using such poor quality parts, its just about knowing what to look for.
Second, quality pellet stoves can withstand the corrosion. Plus, all types of pellet fuel are corrosive. And you need pellet stoves to be able to reply the corrosion for as long as possible, to get the most life out of the stove.
Third and last, pellet stoves that can effectively deal with ash. This will most likely mean that you need pellet stoves, which can deal with ash produced effectively. This may seem obvious, but you would be surprised how many pellet stoves struggle with this core task. Once again, you need to be able to deal with possible clinker formations, which is where the ash melts under high temperatures to form a solid mass!
Think about those 3 reasons. Consider them. Evaluate them. When you think about it, you can see that there are compelling reasons to consider trying to avoid certain makes of wood pellet stoves. Do they really apply to you also?
Seriously now, just think about it for a moment. Don’t those reasons apply to you? Perhaps you really should avoid certain makes of wood pellet stoves.

Fun Photovoltaic Energy Facts: Anyone May Not Have Known…
August 9, 2010 | Leave a Comment
You pretty much can’t escape the dependency on solar energy here on Earth Nobody would be alive, not me or you or any plant or animal, if the sun suddenly stopped burning. Plankton, one of the smallest, most simple forms of life on this planet, must have solar energy to develop and live. Obviously, without any solar energy, you could say goodbye to all plant life on this planet. And if the plants were all gone, all the animals who depend on plants will soon die, and that moves on up the food chain, all the way to us, humans. So while we may not absorb light energy directly like the plants on our planet, we are still indirectly dependent on solar energy from the sun.
Another interesting fact is that solar energy is 100% environmentally safe because it has no carbon emissions. It also is 100% renewable, it is not going anywhere! Solar energy is used to produce electricity and heat all over the globe. At the present time, solar energy is widely used in solar energy water heating systems, which use the heat from the sun to heat water.
Photovoltaic cells can “magically” turn sunlight into electricity by somewhat complicated scientific processes that I won’t get into. The PV panels actually are pretty easy to install. Did you know you can even construct your own set of solar panels?
Also, another neat fact about solar energy is that solar powered cars and trucks are being researched and developed, and NASA even made a plane that travels solely on energy from the sun!
Interestingly, thousands of people have chosen to make their own solar panels. It really isn’t as difficult as most individuals would assume. With DIY solar panels, homeowners can reduce their dependence on the electric company by a great deal!
The DIY solar panels construction guide has shown thousands of homeowners how to build their own solar panels. Its the top-rated DIY solar panel construction manual available today. Visit the Green DIY Energy review to get the full scoop on current promotional price of the guide.
Why Photo Voltaic Energy Is Actually A Smart Option Within The Current Economic Climate
August 7, 2010 | Leave a Comment
For quite a few years, solar energy was basically a form of electric power that many folks failed to contemplate for a considerable power method for his or her household. Standard fuels dominated the energy economy.
But, nowadays, solar power is becoming a viable option for a continually growing number of homeowners, even though fossil fuels still power most of the homes across the world. So why would someone choose to use solar energy instead of coal or natural gas? I’ll lay out three great reasons why people make the smart choice of using solar energy for their homes
One reason people prefer to use solar power to power their home is that it is Absolutely FREE! Indeed, if you failed to know, the sun does not charge a bill every month for us to suck up the energy manufactured by its heat. Coal and gas energy plants send a monthly bill to your front doorstep each and every 30 days, however you will never receive a bill for using solar technology.
Another good rationale individuals decide on solar power over fossil fuel is actually on account of the optimistic results it has on the environment. There is absolutely no damage done to the environment, no harmful gases spewn into the atmosphere and no destruction of natural habitats (each one of these mentioned negative effects are just part of what we have done to the earth by harvesting fossil fuels, like coal and natural gas for many years). It is a great feeling to be running your home with energy that you know is not causing negative effects on our world.
The last reason why individuals may choose to utilize PV energy rather than fossil fuel to power their house is because they can generate and install it themselves for barely any money at all. Bet you would not have guessed you could potentially build your personal solar powered energy system at home, did you? Indeed, it really isn’t difficult for someone with restricted building experience to produce his own photo voltaic panels for under $400, and then get pleasure in experiencing less and less paid to the electric business each month. Since this has become quite popular, there are lots of do-it-yourself guides that show you all you need to understand to make your personal solar panel technology system. Obtain one of those and you’ll have your house driven with cheap, green solar energy very quickly!
Zach Angelo is a DIY expert who loves to show people how much money they can save by installing green energy in their home. He recommends the #1 selling DIY solar panel construction guide, the Green DIY Energy guide. Get the Green DIY Energy Guide at the Green DIY Energy review.

When you know what to do and what things to stay away from, it’s less of a challenge to achieve your goals. You’ll find 3 important ideas to help you which are shown in the following paragraphs. Try these tips and you will be confident of getting a lot better final results.
While you go to look a pellet stoves and wood pellet boilers, it is always important that you do things right. If you don’t, the consequences might possibly be devastating. You may end up been drawn to the stoves and boilers which look the most attractive, or possibly the lowest cost pellet stoves and boilers, which you will regret in the long run. Here are a trio of ways to protect against that from developing.
1. Don’t choose a pellet stove or boiler on looks alone, or even on the maintenance saving features
One must always not choose a pellet stove or boiler on looks alone, or even the maintenance saving features since it helps prevent looking at what you really need the heating appliance to do, which is provide heat reliably. Failing to get this done could mean you end up purchasing a pellet stove or boiler which looks very nice, however lacks the core functions to burn a wide range of fuel successfully. So take care to do this effectively and never make the mistake of neglecting this essential step!
2. Ask the salesman the right questions
Practically as important as not choosing a pellet stove or boiler on looks alone, or even the maintenance saving features when dealing with pellet stoves and wood pellet boilers is ask the salesman the right questions. I am telling you, this is not something to neglect. It will help to get down to the real capabilities of the heat system to be able to provide you with heat at a reasonable price, and that is something everyone involved in choosing a quality wood pellet heating systems needs.
3. Try to purchase a pellet heating system, which can use lower grade pellet fuel
Last of all, when you go to look a pellet stoves and wood pellet boilers you have to make certain and try to purchase a pellet heating system which can use lower grade pellet fuel. This can help with keeping annual running costs down, which is an indispensable part of your choice of quality wood pellet heating systems. If you do not, you might end up with a system, which can only use premium grade pellet fuel, the most expensive pellet fuel — and I presume we are able to agree this will not be the best thing!
As I pointed out from the outset, on the subject of going to look at pellet stoves and wood pellet boilers, you desperately want to make certain that you do not make blunders which end up with you been drawn to the stoves and boilers which look the most attractive, or even the lowest cost pellet stoves and boilers, which you will regret in the long run. What you would like is a middle of the range pellet stove or boiler, which will last decades and can run on lower grade wood and biomass pellets to keep fuel costs down, and you can achieve that by using the strategies presented.
