MODERN LESSONS FROM ANCIENT TIMES

The earliest known uses of solar energy date from way back in the 7th Century BC. 
In ancient Egypt, bricks for construction were made from shaping a mixture of mud and straw into blocks and baking it in the sun.Passive solar design was first used by the ancient Romans and Greeks – who designed buildings that made optimum use of the sun’s rays for heat and light. 
In order to get the maximum benefit from the winter sun, they made sure their buildings were orientated towards the sun.In doing so, they were able to reduce their dependence on firewood which wasn’t always plentiful, using renewable energy instead of fossil fuels.The Romans took solar design seriously, making it illegal to obscure a neighbour’s access to sunlight and using glass for windows.
Energy from the sun was also used by the Ancient Greeks who used bronze shields to focus the sun’s rays onto the wooden ships of the Roman army, setting them on fire.Some native cultures used the natural storage of heat by rocks to good effect by building their homes into the sides of rocky cliffs.
It was not until 1839, nearly 80 years after a solar collector is said to have been built by Swiss scientist, Horace de Saussure, that the platform for modern solar energy development was established with the discovery of the photovoltaic effect by French physicist, Edmond Becquerel.  He discovered that electric current in certain materials could be increased when exposed to light.
French scientists continued to experiment with solar power, with a notable achievement by Auguste Mouchout in developing the first active solar motor as well as a solar-powered steam engine.  Both inventions failed due to high production costs.
Over the years around the world, scientists experimented with solar power.  In 1876, William Grylls Adams discovered that selenium produced electricity when exposed to light, without the need for heat or moving parts. 
In 1921, Albert Einstein who is better known for his Theory of Relativity, was awarded the Nobel Prize in Physics for his theories on the photoelectric effect.
In the 1950s, Bell Laboratories (now known as AT & T Laboratories) developed the first silicon solar cell which could generate a measurable electric current.  It was the first cell capable of converting enough of the sun’s energy into power to run everyday electrical appliances.
The first practical application of photovoltaic silicon solar cells also came in the 1950s with the launch of the satellite, Vanguard 1.The first solar powered aircraft flew across the channel from France to England in 1981 under power from its sixteen thousand solar cells which gave off 3 000W of power.
The Arab Oil Embargo in 1973/4 forced western economies to rethink solar energy research as a means of reducing their dependence on oil.In the 1970s, Dr Elliot Berman designed a less expensive solar cell, which enabled a large number of new uses to be considered, such as railroads, navigation warning lights and homes in remote areas. 
Concern for the environment has galvanised research into finding viable alternatives to fossil fuels, such as wind power, geothermal and solar power.And whilst technologies today are a far cry from baked mud and straw bricks, the basic idea of using solar energy as a viable source of renewable energy remains.

WARMING TO NEW ENERGY

The world’s demand for all energy forms is anticipated to increase by fifty four per cent over the next two decades, according to forecasts by the US Energy Information Administration.   The EIA long-term energy forecast also predicts that world electricity demand will nearly double by 2025. 
The bulk of the world’s energy comes from fossil fuels, such as coal, oil and natural gas.They release energy during burning, but also simultaneously release carbon dioxide into the air.  These conventional energy resources are finite and the emissions harmful to the environment, hence the growing urgency to develop renewable energy sources, such as  wind, water, biomass, wood, geothermal, photovoltaic and sunlight.   
The amount of solar energy that reaches the Earth’s surface is six thousand times the amount of energy that we use on Earth.Humans have used energy from sun since ancient times, but with environmental issues becoming more prominent, solar energy is growing in scale and scope.
Energy from the sun is a workable alternative to the traditional energy sources of fossil fuels, and is mainly used for generating electricity and heating water.  
From enormous sports stadiums and towering skyscrapers to isolated farmhouses and ordinary suburban households, solar power is increasingly becoming the cost-effective energy solution of choice.   For example, the recently completed 55 000-seater stadium in Kaohsiung, Taiwan is the first stadium in the world to provide power using solar energy technology.The 19-hectare stadium was built for the World Games in 2009 and will generate enough energy for its 3 300 lights and two gigantic TV screens through the 8 844 solar panels on its roof.  
That is solar power of gigantic proportion.On a far smaller – but no less important – scale, solar energy provides a cost-effective and low maintenance option for domestic households.
Installing solar panels on a domestic property, homeowners will ultimately reduce their power costs, add value to their property and reduce their carbon footprint, say solar power specialists, Solar My World in Perth.For Perth homeowners looking for solar power, there are two systems available, grid connect and off-grid.
A grid connect system will supply solar power to the household via an inverter, and is generally used in more densely populated areas.And in the likely event of the solar system providing more energy than is required, the property owner may be able to ’sell’ the surplus back to the electricity grid if applicable.A standalone system uses a battery bank to store energy until required.  This system is generally used in remote areas where conventional power supply is unavailable or unreliable.  
A benefit of solar power systems is their versatility – they can be AC or DC designed and can be expanded when needs change.
Energy is the single largest contributor to the world’s greenhouse gas emissions, and as environmental concerns grow, the call for people to reduce their own CO2 emissions is growing louder.  The new stadium in Taiwan that was mentioned earlier in the article is expected to prevent 660 tons of carbon dioxide emissions a year through the power generated from its solar panels.  By making a simple decision to install Perth solar power in our domestic locations, we could all have the energy to save the world.

Planning Your Electric Future

Home owners are correct being concerned about how their energy costs will increase.  They are expected to rise every year with no end in sight.  How high might electricity be ten or twenty years from now?Not only are our energy needs increasing at an unsustainable pace, but supplying the current level of national energy needs is increasingly difficult.  Simply look at China, India, and other large users of energy.  There are slightly over 300 million people in the United States, but there are nearly 2.5 billion people in China & India alone, about eight times as many as in the US. Electricity use is going to increase, so one way to protect your family financially is to install a solar power generating system for your home.

Its A Matter of Finances

A home solar power system may make sense for many reasons.  For some it may be the future financial stability. Because once this source of energy is installed, you will not have to pay for it again, you will reduce or eliminate your dependence on the existing power grid and you can sell excess electricity back to the power company for a profit.Some folks may want a home solar power system to the help the environment.  Solar power is clean. It’s clean because there it produces absolutely no pollution.  At its very cleanest natural gas, oil, and coal are still very dirty and bad for the environment especially when compared to solar energy.  The only way you could call any coal power plant ‘clean’ is by comparing the new technologies to the old.Compared to solar power it is far from being ‘clean’.Also, our supply of all fossil fuels (coal, oil and natural gas) are limited and will eventually run out if we keep on using them.A good decision my be to make the renewable energy switch sooner than later, when those fossile fuel resources do disappear.  And you know as they become more scarce they will increase in price.  Switch now and avoid a catastrophe as billions go without power.You may protect your family from this scary possability by installing your own home solar power generating system. There are many types of renewable energy solutions you may want to look at.

Financially, you will save lots of money (possibly tens of thousands of dollars) over the expected life of your home solar power system. In about ten years your system will have paid for itself and you’ll start seeing your savings add up. Some current benefits include tax credits, to help defray the upfront installation costs of your solar power electric systems.Many potential home buyers may find it an attractive option in the purchase of a new home.  They could simply pay for the solar power system in the cost of the home.  Their savings alone from the solar power system would more than pay for the additional mortgage costs and interest on the loan. You could begin small now and keep growing over time, you may save money by building it yourself.

 

Green Energy from Solar Panels

A solar panel is a surface that can produce energy. This is a type of green energy, that needs to feeding, that can never pollute the earth and which is free. If we care to detail, the solar panels are ways of capturing and using solar energy. There are two major types of solar panels:

- Solar panels used for heating. These panels mainly heat up houses and water sources.

- Electrical solar panels.

Solar panels that are used for heating purposes are generally used for home heating. The mechanism behind these panels is simple, as it is just a matter of transferring heat to a stream of water. So, the water that gets heated can be used immediately or stocked into thermal recipients for later use. There systems are especially useful in areas that are situated far away from civilization, where regular water heating is unavailable, but the owner must be ready to make a small investment at first.

The panels from the second category are the ones that are truly interesting, because they produce free electric power. This whole process is based on the photovoltaic cell. The panels have the capacity of producing electricity in the very moment of contact with sunrays. The base cells of solar panels are grouped into matrixes.

It’s quite clear why these systems are beneficial: they produce free power, which can be used in your everyday needs. Unfortunately, they are not an easy investment, because the initial money they require are quite a few. In time, the costs will be ameliorated. And let’s not forget that solar panels are ecologic, and since out natural reserves are already almost finished, we should take a moment and think about our future.

A current disadvantage of solar panels is that they are not very efficient if they are too small. For the complete powering of an average to small home, you need almost a hundred square meters of solar panels. Reading things like a forex autopilot review can really give you a good idea about placed to look for new money making methods so you can afford all those panels. The fact that they depend on sunlight to function is currently solved with storage systems that allow us to keep the energy and use it during winter days.

Finally, the conclusions are quite simple here. Natural resources will someday be over. Under these circumstances, what will humanity do? Humans will then be forced to use solar power to produce electricity. It’s quite obvious that we will eventual have to install the panels, so why not think ahead and plan the future right now?

Your system you will be able to produce Wattage. How much is up to you and it is mainly depend on the room that can be used for that. You can even build it in a way that the quantity of energy that will be generated will be more than your needs and the surplus electricity can be sold to your power company.

There are many ways to save energy at home from looking at your illumination behavior, using less consuming energy electrical devices BUT the best and most amazing secret is that you can earn money from that and contribute directly to fight the global warming.

Wind or solar energy are one of the less used energy sources. These sources can manufacture sufficient power that can be stored and then used for many things at home from heating to lighting and the additional energy can be sold

Saving power at home is built like a course in which you begin from looking on what you spend, find ways to save this spending or remove it totally while the last and most major activitiy is create a home solar power system or wind power system to provide the electricity needs for your place of linving. 

But before we start we need to ask what are major common functions for energy? 

Here is the short list of things you most likely also guessed alone:   home heating, water heating, lighting, home cooling, refrigeration, electronics in your home, cooking, clothes washing and drying and computers. 

If you want to know more about home energy saving take a look at freepower4home.com site

From looking at this examples you can do genuine savings by taking some small steps to take conrol of them. Below are few guidelines on some tasks you can perform:

Make sure your house heat at cold time or in cold climate when heating does not go over 66°F (19°C).

Take shorter showers or you might want to install water constrictor.

Closing lights is vital when you leave a room.

Buy lower power consuming light bulbs.

Cooling your house at warm time should not be below 77°F (25°C). Other ways of cooling can be use of fan instead of using the air conditioner.

Close your television when not watching (this is one of the biggest electricity consumers in your home) 

When using your dryer or washing machine insert the exact quantity of clothes and pick the right program.

Small toaster oven is much more recommended than the big kitchen oven when heating small bakery or simply warming food.

Homemade Solar Panels

The working principle behind the technical structure of solar panels is the production of electricity by using only certain light wavelengths with the help of photo-voltaic cells. Sun exposure and low or moderate temperature are the only requirements for the panels to work. Though they are usually manufactured by many businesses in the field, a homade solar power panel are also a choice, and many home owners choose to do their own alternative power sources. The kits available on the market as well as the many guides that provide technical details provide the most comprehensive assistance for one who simply wants to cut the electricity bill.

First of all, if the energy produced by a solar system covers around 80% of a the needs in a household, and you did install a very good model, then you will get all your money back through the savings you make from the electricity bill monthly. We could talk about free solar panels in term of a “re-funding” that the system works on your budget. The real return on investment on building your own solar system is obvious within maximum two years in case of a very sophisticated and ultra modern solar system, or up to five years if you’ve purchased an average one.

One major advantage of using an alternate energy power method by building homemade solar panels is that they are environment-friendly, producing what is usually called “green energy”. Unlike other energy source that create electricity, homemade solar panels don’t create any smog or hazardous emissions. If the homemade panels you have already installed prove insufficient for the house needs, you can always add some more to the system. In some states tax reduction laws have been passed so as to be applied for people who choose green energy systems like homemade solar panels. Talk to a tax consultant to learn about the advantages of such governmental policies.

Even with the homemade solar panels you can create two types of utilities: some that are used to generate heat only, and others that produce electricity. The normal panels absorb the sun energy and heat and use it to cover the household needs, whereas the second model relies on the use of photo-voltaic cells for the generation of electricity. Therefore, together with the homemade solar panels you’ll also need a battery as the main storage device, and it is on this latter element that the electricity supply relies. And last but not least the other items required for the installation of the homemade solar panels are the tracking solar mounts.

Exciting Solar Energy Advantages

The many solar power advantages for our world will last for generations. In order comprehend all the solar energy advantages available it is essential to learn how to utilize it.

With solar energy there are two divisions: thermal and light. Building designers utilize thermal energy by incorporating certain energy efficient materials into the design. Light energy used as an green energy source can be harnessed through the use of homemade solar panels or manufactured panels that store up the energy to create a source for power, heating and water heating.

The sun, which is made of hydrogen gas, is a seemingly unending supply of power. We should be encouraged to generate solar energy simply because it is a natural source energy for providing heat and electricity.

There are tons of different benefits to make solar power your main energy source. The main benefit and most enticing of the solar energy advantages is the financial savings. After you have paid for and installed your manufactured or homemade solar panels you will no longer receive that monthly bill from your friendly power company. A variety of financial incentives are available to those who make solar power from the government which will help even further to reduce your overall cost, and solar energy does not require any fuel and in no way contributes to global warming, acid rain and smog.

Solar energy is really all the rage these days, and for good reason. We can all see the damaging effects of global warming which should further encourage us all to make solar power.

If you make solar power you will be helping with the fight against global warming you will also discover that it is definitely worth it to consider switching all your electricity needs to be able to experience all the solar power advantages. Be a hero, make solar power and you will be saving the earth from certain destruction from global warming and saving money as well.

Facts About Solar Energy

The first thing to learn about solar power is light.  Expressly sunlight which is an unending available source of power that can be captured and transformed into electricity and heat.  Second, the electricity produced is an environmental friendly way to get energy and unlike other sources of power, it doesn’t pollute the air.

Solar Thermal Conversion Or Photo-Voltaic

There are two ways of making solar power energy.  One is called thermal conversion which the heat collected from the sun turned into electricity.  The second type called photo-voltaic conversion consists of thin sheets that are made of special material that collect sunlight and generate electricity directly from the sun.

The major advantages to using an alternative green power energy source are that it is very cheap as compared to oil based and other systems of energy production and it is also easily transported from one place to another, which means that even when a person is out backpacking in remote places or lives far from a power grid, by using solar panels he or she can generate electricity to power up electronic equipment.

There are many different benefits that are offered to us by solar energy, and which we should all be taking advantage of rather than letting them pass us by. One of the greatest benefits of a solar energy system involves the economic benefits. Solar home systems provide the least-cost means of receiving high quality home lighting and when low-cost financing is available, monthly payments for a solar home system are often below what a family is currently paying.

The only stumbling block with regard to learning about solar energy is that many times you will be confronted with facts that are really not facts. However, by turning to using photo-voltaic cells to produce electricity, we are moving in the right direction and the good news is that man is constantly striving to make more efficient solar cells so that in the future we can put all that we have learnt about solar energy to good use and save the planet from global warming and other threats.

How About Your Own Solar Electricity System

 Imagine being energy conscious along with millions of people all over the world.  Think about getting a solar electricity system for your home or business.    Solar electricity systems give you reliable and pollution-free energy direct from the sun – meaning it is a renewable resource as long as the sun shines.    Because of more interest in alternative energies, advances have been made in photovoltaic designs and the construction of solar electricity systems are becoming more affordable to the common person.

“Net metering” is another benefit made available in many states.  ” Net metering” is this.  Your home is connected to your utility company through a meter.    With your solar electricity system hooked up, when you generate more solar power than you are using, your meter runs backwards and builds a bank of power that you can withdraw when your solar electricity system needs help.

 

Although relatively easy, it is best that you understand the workings of your solar electricity system before you begin.  The prime element at present is the photovoltaic cell.  Modules are made up from multiple cells wired together.  An inverter takes the electricity produced by the cell from the sun’s energy and changes it from DC (direct current) to AC (alternating current), ready for your use and utility grid hookup.  For backup, batteries can be integrated into your solar electricity system for use on low/no sun days and power outages.

 

Speaking of low/no sun days – very few places have the sun shining every day – you have to realize that fact – your solar electricity system does need sunlight.  That is a good reason for the backup batteries talked about above.  

 

You should also know that some purchased systems can be expensive – up to $10,000+ (which can take some years to pay with the savings on utilities you generate).  But remember net metering paybacks.  Further, grants and rebates are available from the government to help with costs.

 

You definitely don’t need to be an engineer or know the physics of solar electricity systems to understand the appeal.  A  solar electricity system will never run out of fuel,  If it does, none of us will have to worry about anything.  It can decrease our dependency on foreign oil.  Stop just thinking about a solar electricity system for your home or business and make the move to get free by starting your research of  solar electricity systems today.
