HOME ENERGY Generation Systems

Creating Home Energy Generation Systems

When you are tired of paying for your high home energy bill month after month and would like see some changes and feel some savings, then, there is a right thing to do: invest on one or more home energy generation systems.

The home energy generation system is the solution if you want to cut those bills down and utilize alternative energy around you just waiting to be tapped anytime. The home energy generation system provides you with the best way to get the maximum financial freedom on home energy. Sure, you have to invest first but it is all worth every penny. You can spare yourself from the present cost of home energy and the future increases that may occur. And most of all, investing on the home energy generation system will definitely help the environment for it only uses a harmless and clean source of energy.

Among all types of alternative energy that can be used, wind energy and solar energy are the most common.

Wind energy

Wind is very abundant in many parts of the country, thus, many households can capitalize on the use of wind as a source of home energy. It is also said the future’s main source of energy would be the air. As the cost energy production through fuel and oil grows increasingly high for the last years, the clean, safe and free air would be the better choice for the future.

As a main source of power for your home, it provides the financial freedom on the use of energy sourced from the expensive oil. However, wind speed varies on a daily basis. One day, the wind will blow strong. The next day, the wind may not be able to keep your turbine spin. And even on the breeziest places in America, you can never tell when will be the next strong wind blow occurs. This is one disadvantage of using wind power but wind patterns do exist. It is said that summer brings less wind while the winter brings a strong gust of wind.

If you are planning to install wind turbines on your home, make sure that the local zoning allows wind turbine. You must also ensure that there is a good source of wind on most days. A wide and open space, at least 1 acre, would be ideal for wind turbines. And, if you are paying more than $150 on the monthly electric bill, then it may be a good option for you.

There are 5 main components of wind power.

The rotor is the set of rotating blades designed to capture air. The rotation brings power to the generator.

The turbine or the generation is the one attached to the rotor. It stores energy that the house will use.

The tail is located opposite of the rotor. It tracks the direction of the wind.

The tower raises the turbine, rotor, and tail up to the air to receive the most amount of wind possible.

The governor is the mechanism that controls the production of energy. This is like the transformer you can see on electric posts.




Solar power

Houses that are built under the sun will compensate on the free solar energy.

There are 6 main advantages of installing solar panels on your roof.

1. Solar panels are lightweight, safe and most of all, easy to install. These are essential in order to place them above your roof.

2. The roof is also susceptible to UV exposure. The solar panel eliminates this. Your roof will also be protected from the weather.

3. Solar panel contributes to keeping your house well insulated. They provide extra covering and enable you to save as much as 30% on heating expenses.

4. Drilling holes in your roof is very risky. The interlocking solar panels eliminate this risk.

5. Solar panel design is perfect on any roof type and size. In other words, you can get the perfect solar panel no matter what the size and shape of your roof is.

6. Solar panels are installed without requiring you to modify your roof. It will adapt instantly.

Solar power will tremendously help you cut down the cost of your electric bill. If you think you are in for this investment and if you think your location is most suited to have this, then the choice is fully yours.

SOLAR HOME ENERGY: What is it for?

Solar energy—this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple. Everyone knows what is meant by solar energy, and that is, the energy that comes from the sun. In its most basic sense, solar energy and other solar home equipment are nonetheless environment-friendly and not risky at all. But then you need not become one fine environmentalist first before you will be able to come across with whatever advantageous benefit solar home energy has.

Why is the solar home energy said to be environment-friendly? What are its general benefits? Practically speaking, when solar home energy is used, the electrical bills tremendously go down as compared to the other type of home energy available for all people. Why would you pay for such expensive bills when all you need to do is to employ solar home energy? 

Another major advantage of the solar home energy is the absence of the very complicated and dangerous wiring. Solar energy lights in the garden path or any other solar energy-powered items used in your home are ready to be installed less the wiring to be dealt with. In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned on to give off the light and they need not be turned off as well when they are no longer needed. 

As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes, installed, and then presto! You just have to situate them where you want them to be and never worry about them ever again.

A List of the Benefits of Solar home Energy

Why is the solar home energy equally beneficial? Why is it more recommended for use? Here are some of its benefits which are truly worth the attention to be graced by anyone:

Solar home energy is environmentally friendly. As mentioned a while ago, solar home energy will not harm the environmental features. It is specifically clean and renewable as well. More so, it does not cause pollution just like what the rest of the traditional electrical forms do.

Solar home energy systems need the least maintenance. They are not fuel-powered so no need to buy the refills. 

Solar home energy makes you save a lot of money. The energy that is derived from the sun can be accessed for free as you make use of solar lights, solar panels, and the likes. The federal government most of the time gives out financial incentives. You don’t get affected by the rise of the fuel rates since you are using solar home energy.

Making use of the solar home energy makes you entirely independent from the foreign and centralized energy sources. Power outages will not likely affect you in any manner.

Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems. 

Some Common Disadvantages of the Solar Home Energy

Of course, the disadvantages will not be taken aside. Here are some of the most common disadvantages of the solar home energy:

The employment of a solar home energy can be expensive at first. But as time passes by, it becomes a light to the pocket.

The strength of the solar home energy will relatively depend on the location of your home in relation with its facing to the sun. Also, the area of your home is another point to consider. You will need large areas to install the solar panels.



The Various Solar Energy Items

There are lots of solar energy devices that you may opt to buy. Included are the solar flashlights, solar heaters, car ventilators, solar video cameras, solar radios, solar pool purifier, solar mosquito inhibitor, solar lighting, and solar fountain pumps.

What You Must Do

Back in the earlier years, solar energy powered devices were very costly that very few homeowners made use of the solar home energy. But these days, small volumes of solar energy devices are put up for sale, therefore, making it affordable for all. If you don’t have enough money to fund these items you can always start small.

Is SOLAR POWER Really Worth the Cost and Trouble to Save Money on Your Power Bill?

Want to generate your own home electricity? The first solution that comes to mind for many people is solar power. Use the sun to make your own electricity. Sounds easy, right? What some people fail to stop and think about are the actual returns you'll get from setting up your own home solar power solution. 

There are countries around the world that actually encourage home owners to install some kind of solar setup and they do this by offering grants or cash backs. It sounds good so far until you actually take a look at the costs involved and what it means for your house. Is it worth installing and setting up solar power in your own home? This is a tricky question, because there answer is both a yes and a no.



Solar panels are definitely worth installing in your home if doing your little bit to save the planet is high on your list. The reason for this is because the setup costs are high and you will need a lot of disposable cash to setup any kind of solar solution to see a significant drop in your home power bill. Why is this? The high costs come from the photovoltaic cells which are the heart of any solar power setup. This PV cells make it possible to convert the sun's energy into electricity. While prices have come down over the years they are still extremely costly and the majority of home owners just won't be able to justify the high cost considering the small savings you get in return.

While it would be nice to be able to do our little bit to help save the planet, the truth is that everything in life has some cost associated with it. Because of the high price of PV cells, many home owners just can't afford to install solar power. Another problem with solar power is that the amount you spend on it does not necessarily translate into an investment in the value of your house. Spending 10,000 USD on solar power does not mean your house will rise in value by that amount. This can be said for installing a pool, as the high cost of the pool does not equate to an equal rise in value of your home. The amount of money governments give you is very little compared to the cost of solar panels and the small savings you will get in return. Solar power is great in theory, but sadly that is as far as it goes.



Another alternative to solar power are magnetic generators. A magnetic generator is a generator that is able to create clean home electricity but does so using much cheaper parts. They run off magnets alone and this translates into an extremely low cost alternative power solution. Their small size and low price means that almost anyone in the world can install a magnetic generator, make home power and see savings of anywhere from 30 - 50% off their power bill.

Storing ENERGY

We have come to rely completely on energy.  We use it in almost everything we do; we live in it, use it for all our modern conveniences and more.  Without energy we wouldn't know what to do.  In the past, before energy, there were lanterns for light and matches and wood for heat.  That was the only options people had.  When power was accessible to everyone by running power lines through cities, towns, residential areas to allow everyone to tap into the new generation, people were skeptical as to how this would affect everyone in the future.

Alternative Energy - Photo by the russians are here 
Over the years, appliances became energy friendly, which made for less manual labor and more free time.  Wash machines, dryers, dishwashers and the latest in cooking stoves that no longer needed wood.  These were all great inventions and although people were skeptical they still took advantage of these appliances.  Today we have the worry of saving the energy that we know and love so well.  Our energy is fueled by non-renewable resources which will allow the depletion of these resources slowly and over time where we won't realize it until it is gone. We need to find an alternative to the way we power our energy but we also need to store the energy that we already have.

Solar energy has been tested and experimented with as we learn more and more about how to conserve and store the natural heat from the sunlight.  We all know how effective it is and why it is something that we should work very hard at conserving.  Storing the solar energy can mean endless usage of water and other necessities by using conservative methods of saving energy.

Thermal mass systems are the process of using natural resources to make material that will store solar energy.  This type of storage uses renewable resources from the earth, such as dirt, water and man made resources such as concrete to help store energy if only for a short period of time.  Thermal mass can help heat water at night or heat your home long after the sun goes down or on cloudy days when the sun doesn't peak through the clouds at all.  These need to be worked on because there is no extensive long storage capability using solar power just yet.

Then you have the thermo-chemically phase which uses types of devices to store heat.  Some examples of this type of storage includes

Paraffin wax inside of a storage tank.  When the paraffin wax is cold it is solid but when it is heated it is a liquid that can help hold heat for a very long time without cooling it down. As the paraffin wax cools it becomes hard which can hold the heat in longer.

Eutectic Salts are inexpensive and can store heat in a heating system which will distribute the heat evenly and lasting hotter longer.

Molten Salts are an effective way to store solar energy because it allows the heat to remain hot without being non-flammable and cost effective.  During the time that the storage tank is heating up, the salt mixture is heated and then used to make steam.



Rechargeable batteries can be a great way to store energy.  This type of storage allows the power source connected to the battery maintain its power.  Lead acid batteries are the more common battery used for this type of storage.

As you see there are several ways that we can store natural energy we just need to learn how to make these methods more practical and efficient.  When we figure it out we will have an unlimited supply of natural heat.

Essentials of a SOLAR GREENHOUSE

Plant breeding and plant production is a very productive hobby and livelihood. It is good way to earn some living by producing high-valued crops. It is also a good way of contributing to the environment. The best way to sustain this endeavor is to get a solar greenhouse. Read on to learn the basics of the solar greenhouse.

SOLAR GREENHOUSE OWNED AND BUILT BY PETER HOWE...
 (Photo credit: Wikipedia)

What Is a Solar Greenhouse?

The very purpose of any greenhouse is to collect solar energy whenever the sun shining high. However, solar greenhouses serve a more specific purpose. It is able to do more than collect the solar energy. The solar greenhouse is able to store heat that can be used during nighttime, cloudy days or the cold season. It provides adequate heat that the plants will need for their growth even during the night time or the cold seasons.

The good thing about solar greenhouses is that there are choices to choose from and to suit the needs of the owner.

They can stand alone. This is very ideal for big production greenhouses.  The freestanding ones are ideal for commercial production. These are used to produce ornamentals or vegetables. They have two primary designs, the shed type and the Quonset type.

The shed-type has a long axis running from the east to the west. It has a south-facing wall glazed to collect maximum amount of the energy from the sun. The north-facing wall on the other hand is very much insulated to avoid heat loss. These features are what contrast a solar greenhouse from the ordinary ones.

The Quonset type can sometimes look like an underground pit. This is a low-cost greenhouse. It has a Quonset-shaped frame and looks like a tunnel. It has a layer or two of plastic film. This can save as much as 40% of the heating fuel.

They can also be merely attached to the greenhouses, very ideal for backyard use. The attached solar greenhouses are structures that form some sort of a room protruding from a house. This is a good space for transplants or herbs.

Passive or Active

The solar greenhouse is classified into two. It can be the passive solar greenhouse or the active. These two makes use of different resources, but still serve a same purpose.

The Passive Solar Greenhouse

In some places, where colder seasons tend to endure longer, there may be a need to resort to passive solar greenhouse, using gas or electric heating system. This is the only way to protect the plants from getting too much cold.
This is very ideal for growers as it can still give way to so much productivity despite the conditions. The use of heating systems for greenhouses to be cost-effective is best utilized if there are high-value crops to be produced.

The Active Solar Greenhouse

The active solar greenhouse makes use of supplemental energy. It transfers the solar heated air from the storage area to the other parts of the greenhouse.




Designing a Solar Greenhouse

Most would claim that managing and maintaining an ordinary greenhouse does not differ much with the solar greenhouse. However, there are a number of ways that they differ. These are significant distinctions.

Solar greenhouses, unlike the ordinary ones, have oriented glazing to get utmost solar heat, even during winter. Its materials are designed to minimize loss of heat. It uses heat storing materials. It also has insulation especially useful when there is no sunlight. The solar greenhouse also depends heavily on natural ventilation for cooling during summer.

Solar Heat Storage

This is one main feature in designing a solar greenhouse. To remain warm even during cool nights, there must be sufficient amount of solar heat stored. One common method used to store this energy is to put rocks or concrete directly receiving the sunlight to absorb the heat.

Cinder block walls at the north side of a greenhouse are also used as good heat storage. Dark-colored ceramic floorings can also be used to store the heat. Any wall or flooring not used for heat absorption is supposed to be colored light. This should be designed to reflect the heat and light and distribute it to the plants.

The management of a greenhouse can also determine the amount of heat stored. A greenhouse that is full of plants and structures can store heat easier compared to an empty one. Composts can also complement the heat storage goal as they help produce carbon dioxide in the atmosphere. Furthermore, the microorganisms in the compost also contribute to the increase in plant production.

Some would rely on any structure that would resemble a greenhouse to accommodate the plants. However, to be efficient and cost-effective, aim for the optimum setting in your solar greenhouse.

Harnessing the SUN for Your Home – Key Components

Using the power of the sun is becoming increasingly attractive from an economic and environmental aspect. If you’re going solar, you need to know the components.

Solar Components

While generally considered electric platforms, solar systems definitely have unique components. Here’s some of the jargon you are going to need to be familiar with before buying.

A photovoltaic (PV) module that is composed of...

1. Photovoltaic Cell – This is the key piece of any solar platform. Known as a PV cell, it is typically a small cell containing a silicon substance under glass. When the sun hits the cell, the silicon undergoes an electrical reaction that creates a charge. The charge is collected by small wires. Depending on the nature of the cell, each should produce roughly half a volt.

2. Solar Panel – A collection of solar cells joined as a unit in a frame. A single panel typically is insufficient to produce enough energy to power anything of significance in your home.

3. Solar System – Also known as a photovoltaic system, a solar system is an interconnected set of solar panels. This is what you see on the roofs of home or other areas around homes and buildings. A solar system converts enough sunlight into electricity to provide most or all of the power required by a home.

4. Orientation – Before installing a panel system, one has to give some thought regarding where to put it. The sun tracks across a structure in a particular way. To maximize the energy production, the panels have to be oriented to receive the maximum amount of sunlight. This, of course, results in the maximum amount of electricity.

5. Direct Current – A type of electricity that flows in only one direction. Solar cells produce direct current electricity.

6. Alternating Current – Electricity that flows in both directions. AC power is used by utilities and in practically all appliances and machines in a home.

7. Inverter – A key component in a solar panel system. The inverter converts the direct current produced by the solar panels into AC power that can be used in the home or fed back into a utility power grid system.

Obviously, there are a wide variety of systems for converting sunlight into power. Making yourself familiar with the above components is a good place to start.

Global Warming and BUILDING GREEN

Building green is one of the solutions to global warming that many people do not think about. 

Building green is designing and constructing buildings with the environment in mind.  It is these practices that can have an impact on stopping global warming.

Houses give off a high percentage of a country's total carbon dioxide emissions.  In the United States, the figure is about 38%.  Since carbon dioxide is one of the greenhouse gases, houses contribute strongly to global warming.

Scientific studies on climate helped establish...

One way to cut the greenhouse emissions of houses, and therefore help stop global warming, is to minimize the energy use needed to sustain comfortable living in a house.  There are several ways to do this.

One way is to be careful about what building materials are used.  Some building materials can be from quickly renewable sources.  These include bamboo and straw.  Also, building materials can be used that originates near the building site.  This cuts down on transportation, and so cuts down on emissions of greenhouse gases and global warming.  One example is stone houses built with local stone.

Buildings are also often built using recycled materials.  Wood can be used from an older home that has been torn down.  This will prevent the need to cut down other trees.  Since the deforestation of the land contributes to global warming, this will help the situation.

Heating and cooling have a big effect on the amount of global warming caused by a house.  Some ways to help this are very simple.  One is to design the house to sit on the lot so that sunlight will come in through the windows and warm the house.  It can also be oriented so that breezes will blow through the windows more naturally for cooling.


In this way, passive solar energy can be used to heat and cool the house.  This will cut down on the greenhouse emissions from a house.  Global warming will be lessened.  Insulation is important to maximize on the cool or heat that is in the house.  With good insulation, you will need a less intense heat or cooling source.

The main heating and cooling source in most green houses will be solar panels, wind power, or hydropower.  Any of these sources will power a house with minimal effects on global warming.  At the same time, these sources of energy will sustain a household in a comfortable style.

There are several organizations in the US that aid in the cause of stopping global warming by encouraging green building.  One non-profit organization makes it their business to foster green building methods in both houses and commercial buildings.  This group of people from the building industry is a part of the Green Building Initiative.

The state of Washington has required builders of buildings larger than 5000 square feet to use green building practices.  Their law was enacted in 2005.  It should help to keep a cap on global warming.

Green building is important for a number of reasons. One just happens to be that it can reduce the emissions of greenhouse gases.  If green building can help stop global warming, perhaps it is time for everyone to build green.

Build Your Own Homemade SOLAR PANEL to Use Free Energy in Your House

Now is a great time to think again your spending plan. The economy is in a hard shape and the majority of people have little or no savings left, and no admission to credit. So, one of the greatest things to do is seek out ways to reduce your financial outlay. You can without doubt make a big dent in your power budget by knowing how to build your own home made solar panels with items you can acquire in virtually any hardware store.
English: Solar Panel
(Photo credit: Wikipedia)

Solar electrical energy is not as complicated as it sounds and not at all as difficult or costly as it used to be. As a consequence of our dependence on foreign oil and domestic coal, it has been essential for our government and industry to put money into solar power systems. The change in the way solar technology is harnessed is wonderful and nothing like what it was once. You no longer have to have your entire roof covered in photovoltaic cells to build enough electricity to electrify your property! You can do it with a much less investment and even produce enough electric power to trade back to the electrical company.

In order to build your own homemade solar panel, you must be in a position to follow instructions to generate the panels that will soak in all of that solar energy. Even if you reside in a family house or condominium, or run a company, you can locate a smaller sized solar panel on your home and begin producing electricity the identical day. At the finish of the month, you will notice the main difference in your utility bill.



If you are thinking of how to make homemade solar panels work for you, the are numerous online resources that are available. With a small investment, you can lower your costs on your utility bill, create a nice tax deduction, and even boost the value of your house!

ENERGY-SAVING DAYLIGHT For Dark Spaces

There's light at the end of the utility bill tunnel, thanks to an easy-to-install skylight that not only brings light to dark spaces, but also helps cut energy costs. That savings is not insignificant, as Americans spend 20 percent of their electricity bills on lighting their home.

English: Shows benefits of collimating tubular...
Shows benefits of collimating tubular skylight. (Photo credit: Wikipedia)
Called tubular skylights, they are ideal for situations where there just is not enough light and the homeowner doesn't want to install a more traditional lighting system, explains a spokesman for ODL, the Michigan company that makes the skylights. They're perfect for bathrooms, hallways, closets, laundry rooms and just about any room in the house.

Easy To Install

In addition to being Energy-Star qualified, the skylight is also easy for homeowners and contractors to install. A new two-piece installation kit makes installing the skylight simple because the bottom adjustable tube overlaps the top adjustable tube. Just cut a hole in the ceiling and a corresponding one on the roof. Slide in the dome flashing under the roof shingles and attach the reflective tubes. Cap them with the ceiling covering. You may download detailed instructions and watch video clips at www.odl.com/sky lights.

The skylight features a patented Solar Lens Dome, which increases light through the tube. During the full midday sun, a 10-inch tubular skylight lights up 150 square feet of space with a solar throughput equal to about three 100-watt bulbs. The 14-inch tubular skylight is designed to light up 300 square feet-an output equal to about five 100-watt bulbs.

ODL also offers a 10-inch and 14-inch Severe Weather Tubular Skylight, for areas where hail or hurricanes are common.

Heating Water using SOLAR POWER

When you decide to convert your main power source over to solar power you will need to make some adjustments to the appliances that carry the power source.  When you use solar power to heat your water you may find that you will need to purchase a solar powered water heater in order to do that. You may be able to make adjustments to your existing one but what ever steps you take to turn it into solar power it will be worth it.

Photo  by WalterPro4755 

There are several different ways to heat your water using solar power. You can even make your own solar power source.  The water runs through pipes before it enters your home. Heating water using solar power will occur before the water gets into your home as it passes by the solar source that attracted the light. You may also have a tank to store the water in that can heat the water up. In order to heat your water successfully you will need to have both a solar collector and a storage tank.

A flat plate collector is the most common collector. It is designed to be a thin, flat rectangular box that has a see through cover and it can carry fluid to be heated.  This fluid could be the water or it may be a solution, such as antifreeze that will prevent the water from freezing. Next the water moves through the tubes to an absorber plate.  This plate is painted black to attract and absorb the heat from the sun.  When the collector gets hot, it will heat the fluid that passes through the tubes. As the water passes through the tubes it goes into the storage tank. The storage tank holds the heated water.  It is usually well insulated so the water will stay warm longer.  Then the water flows into the home on demand.


Solar water heating systems are divided into two groups: Active and passive.  When the heating systems are active, that means that they rely on the pumps or other mechanical device that can move the water between the flat plate collector and the storage tank.  Active is the most common because it is quicker and more efficient.  The passive system relies on gravity to feed the water from the flat plate collector to the storage tank.  This may be slow at times and may not be sufficient enough to keep up with the demand.  Both ways are logical and may be more of a choice of preference for you.  Another thought that you need to consider is that if your flat plate collector and your storage tank is not angled right it may be hard for the gravity to feed the liquid through.

Heating water using solar power is very affordable and can be installed with minimal effort.  Choosing to heat your water using solar power is a wise choice and a first step in making a choice to help preserve our environment.  We know how easy it is to use solar power to do a lot of things, including heating our water.

Sustaining Life: SUSTAINABLE POWER

BioEthanol for Sustainable Transport
BioEthanol for Sustainable Transport (Photo credit: Wikipedia)
When we speak of energy, power, and development, we all think development, industrialization, advancement; all these leads to pollution and degradation of the environment. You hear advocates say that our environment was a lot purer in long gone ages because people do not use energy.

Who’s Liable?

That is not necessarily true; you see ancient man used fire to cook things, and then the sun to warm them up. Even humanity itself uses energy to be able to move and go about life each day. We cannot survive without energy and yet we blame it for the destruction of our planet. It is us who use energy to no ends, it is us who abuse its use therefore we are liable to find the solution to pollution. It is our responsibility to our selves and the future generation to seek ways of supporting our way of life without harming the environment.

The Scope and Definition of Sustainable Power

Generally sustainable power is thought to be any renewable kind of energy. Meaning it is any puissance whose source cannot be depleted and does not contaminate the environment on a long term basis.

Although sustainable power maybe confused with alternate or green energy the two are distinctly different. Sustainable power is conducive to nature but it is set apart from green or alternate energy because its source is unending, it cannot be exhausted.


Power Source

Sources of sustainable energy vary. It can be as simple as hydrogen to as complex as nuclear energy. When we speak of sustainable development we must consider the basics before heading of to the complex, after all we haven’t used the newly scientifically discovered energy long enough to know its possible effects. The first things to consider are those that nature itself supplies; like the air, wind, solar, tidal, and water resources.

Techno Speak

With all the media hype surrounding this idealism you’d think that we aren’t already using sustainable energy! Yes, we already are using alternate energy resources. We have water dams, the waterfall power plants, wind mills, geothermal plants, and the nuclear power plants.

There are three technological classifications for the technologies that help us attain sustainable power; these include biomass combustion, hydropower, and geothermal plants. First generation power automatons arose during the industrial revolution. This is the time where people discovered that manufacturing will become faster thru the use of machines, and faster output means larger sales. In a way sustainable power was researched and invented not for the future but for the moment; to improve lives, industry and the economy.

Second Generation energy resources comprise wind power, various forms of modern bioenergy, solar photovoltaics, and solar energy. These technologies emerged from the need to depend on oil so much. Research and Development was massively funded during the 1980’s and we are now reaping the benefits.

Third Generation sustainable energy resources are those that relatively new; biorefinery technologies, ocean energy, hot dry rock energy, biomass gasification, concentrating solar thermal power and even nanotechnology may make future appearances that will hopefully end our quest for continuous energy sources. On the stage of research and experimentation these resources are still under development but raise the hopes of those who continually seek sustainable power.

All that have been mentioned are technological advances and discoveries of everlasting energy source, but in the end like everything in our lives, the future is in our hands. Even when we are provided with more nature friendly energy resources if we don’t conserve and use it wisely we will still end up damaging the very planet on whose existence and well being we very much depend on.

From SOLAR POWERED Homes to SOLAR POWERED Boats?

Green technology is currently on the rise, especially after the new stimulus plan in which the government is using it's resources to enhance the use of renewable energy. With the effect of many conventional technology uses, the environment has been on planet Earth's radar, with many individuals taking action either installing green technology to their homes, or spreading awareness of the positive effects of renewable energy. One of those individuals are Raphael Domjan a former ambulance driver who started a Swiss company PlanetSolar has created the worlds largest solar-powered boat to travel over 34,000 mile journey.

Solar power technology is truly limitless, this is a hopeful story of the many uses of renewable energy being implemented in other area's of technology besides creating solar powered homes. The solar powered boat is named the Turanor, a word taken from J.R.R. Tolkein's "The Lord of the Rings." It means "power of the sun." The boat was constructed by engineers and scientists from PlanetSolar, financed by private funds. Raphael has started this project to encourage other's to produce solar powered transpiration machines, and to create a growing awareness of renewable energy.

Solar power is the technology for the future. This powerful technology brings you many advantages such as free energy, zero release of pollution or harmful chemicals, light weight, and reliable. Generators can always go bust, but solar power is here to stay. However with the many pro's of renewable energy, it has it's share of cons as well such as expense, production, and implementation. Solar or renewable energy is very expensive to produce, also since it's such a new technology it is very complicated to implement and produce. But these are only barriers that will be overcome by our new research facilities all around the world, and new scientists spending their time developing and enhancing solar technology for the betterment of mother earth.

An Untapped Source Of Eternal Energy: What Is SOLAR ENERGY?

The most exact definition of Solar Energy is plainly – “the energy from the sun”. It is a term used to classify the electromagnetic radiation emitted by the sun and intercepted by the Earth. It is the world’s most permanent and reliable source of energy and the most copious.

The uses of solar energy on earth include solar heating for buildings, solar heat for manufacturing or industry and electricity production. So what is solar energy? How does it affect us?

Solar energy is responsible for weather systems and ocean currents. It provides light, heat, and energy to all living things on Earth. It has many uses. It supplies electricity; it can be used to power cars.

Solar energy is also used as a power for satellites in space and in space shuttles. It could also power boats, generators during emergencies, toys, and even security systems.

The amount of solar energy that the earth receives is about 770 trillion kilowatts (kW), an amount 5,000 times bigger than the sum of all other energy, may it be terrestrial nuclear energy, geothermal energy or gravitational energy.

There are two types of solar energy. These are:

1. Thermal Energy
2. Electric Energy

What is the difference between the two types energy?

Thermal energy is kinetic energy. It is everywhere. It makes the earth hot and even heats up our homes. It helps us to dry our clothes. It is used as well to heat up water for household use or even pools. That is why thermal energy is called the heat energy because it is stored in the center of the earth as well.

Electric energy is widely known to us as the electricity. It is an essential part of nature and it is one of our most widely used forms of energy. This uses sunlight to power ordinary electrical equipment, such as household appliances, computers, and lighting.

Most applications of solar energy depend on systems including collectors, storage and controls. Storage is needed for a reason that solar energy is only available at daylight hours, but the demand for energy is needed both day and night. Controls are used to guarantee that the storage system works safely and efficiently.



The accessibility of solar energy is determined by three factors:

• The location is usually measured by latitude, longitude and altitude.
• The time.
• The weather.

Aside from knowing that solar energy is a free energy still, you have to realize that it also has advantages and disadvantages.

The advantages are:

• Solar energy is almost limitless; it will be available for as long as there are still humans in the earth.
• It is abundant. You will not worry of running out of it.
• It could provide more power than all known fossil fuel reserves.
• Solar energy is available during the day when electricity usage is really important.
• It is the most inexhaustible, renewable source of energy known to man.
• Solar energy can be absorbed, reflected, transmitted, and insulated.
• It can be collected and stored in batteries.

The disadvantages are:

• It is not suitable in cloudy areas.
• It is not available at night time.
• And it may require large land areas.

As a reminder, solar energy levels are lesser the farther north the site. Considering geography, season is an important determinant of solar energy levels because the Sun’s position and the weather vary greatly from summer to winter.

A Key Element In SOLAR PANELS - Efficiency

While solar energy is most often associated with the production of electricity, heating is also a major platform. While heating isn’t particularly difficult, efficiency in doing so is the key to saving wear and tear on your system.

The sun produces a ton of energy, but solar panel systems have historically been very inefficient at converting it. With improving technology, efficiency has improved to the point where most panel systems can easily produce enough energy to heat water for the home and pools. There are efficient and inefficient ways to go about this process.

To save wear and tear on your panels, you need to consider a flow control system. Older panel systems tend to take a long time to heat up fluid because water more or less randomly circulates through the system. This is very inefficient because the panels are forced to heat up a much larger pool of water than you actually need. This results in wear and tear, not to mention lengthy waits for hot water.

A control flow system attacks the efficiency problem by reducing the amount of water that must be heated. Most are designed to work on temperature differential strategies. They work by using two sensors. The first is located close the panels being used to heat the water or liquid substitute. The second is located on or close to the liquid return valve into the panel system. Put in practical terms, one sensor measures the temperature of liquid set to leave the panel while the other measures the temperature of liquid coming into the panel.

Flow systems work by waiting for the liquid to rise to a temperature determined by you. Once the liquid meets the temperature, the system turns on the circulation pump and moves the liquid to the desired location. Once the return valve sensor notes the temperature of the returning water is within a particular range of the liquid in the panel system, the pump is shut off. This process allows for faster heating times, more efficiency and less wasted energy.

Solar solutions are coming to the front of the energy debate for many residential energy needs. Countries like Germany are making huge investments in solar platforms and technologies. Solar can be a cost-effective solution for you as well. Just keep in mind that flow systems are a must if you are pursuing solar water heating.

Are There Any Problems With SOLAR POWER?

The question "Are there any problems with solar power?" is one that comes up quite often when people are investigating the possibility of investing in solar energy.

This all comes back to one of the major problems with solar energy in particular and renewable energy in general, and that is the lack of knowledge and information about these incredibly powerful alternative forms of energy. While this problem is gradually being addressed as more and more people track down the information they need, it's still not as readily available as it could, and should, be.

So, let's go some way to redressing this situation and give some answers to the question "Are there any problems with solar power?".

Basic Understanding

As already mentioned, one of the major obstacles to the widespread embrace of solar power is the lack of knowledge of just how it works. Most people, if asked the question, "What does solar power mean to you and what can you tell me about how it works?", would probably answer that it's all about having solar panels put on your roof and getting electricity as a result.

Well, that's part of it, but what about the type of electricity that solar panels generate? How do the solar panels actually generate that electricity? If you're connected to the grid, how does the electricity get to the grid and then to your appliances?, etc.

There are a myriad questions surrounding solar power, and its use, but how many people have the answers to these questions to be able to make an informed decision as to whether or not they might be able to benefit from solar energy themselves? The answer, sadly, is probably not as many as there should be.

Initial Investment

There's no denying that purchasing a PV (photovoltaic) system can be a fairly expensive undertaking, but what most people fail to take into account is that this is not an investment that will help them turn a profit overnight and then they can move on to the next investment opportunity. This is an investment in their - and the environment's - future that will repay the initial cost manyfold in both tangible and intangible ways.

The most immediate benefit will be to the environment, because the home with a PV system will draw less power from the grid, meaning less fossil fuels burned, and, therefore, less pollution. The long-term benefit for the homeowner will be that, once the system's paid for itself, usually within 5-10 years, they will be getting their electricity free of charge, and that electricity will be there each and every day from when the sun rises to when it sets.

The Nighttime's NOT The Right Time

And there is another of the problems with solar power, the fact that there's only so much sunlight each day. Granted, depending on where you live, such as areas like the so-called Sunbelt states in the U.S. (including Florida, Arizona, New Mexico, etc.), you could receive massive amounts of sunlight during the day, especially in the summer months.


But, still, night comes, and then what happens? How do you get electricity from your solar panels then? Well, the answer is, you don't. Once nighttime hits, or it's very cloudy or overcast, solar panels generate little or no electricity, so, if you're on the grid, that's when you draw power from the grid. The great thing here, though, is that, with grid-tied systems, your solar panels have been feeding energy into the grid, giving you "credits", during the day, which you can then withdraw at night. If you're off-grid, you need batteries to store energy, which you then draw from at night.

So, the answer to the question, "Are there any problems with solar power?" is "Yes, there are". But, the good news is that these problems are far from insurmountable, and, with greater knowledge and awareness, what once were seen as problems can eventually be seen as benefits.
