An ALTERNATIVE ENERGY Education Method

The best method of educating young people about alternative energy production that this writer has ever witnessed is the use of the PicoTurbine Company's kits, books, and projects. The PicoTurbine Company produces these things for the purpose of advancing the cause of renewable (alternative) energy and getting young people to look into the future and see that the environment that's being seeded now is the one they will inherit them. As the late, great Gerry Ford said, “Things are more like they are now than they have ever been before.” If we are to change the future world for the better, then it starts right here and now with the advent of “green” energy systems.

One of the core concepts of PicoTurbine can be stated: Tell me, and I will forget. Show me, and I might remember some of it. Involve me, and I will master it. Based on this old tried and true adage, the kits that the company produces come with activity suggestions to get the young people into hands-on learning situations. One suggestion of the company is to demonstrate how heat can be produced by wind energy (the company's speciality) through using a “picture wire” for the heating element. PicoTurbine has found that people typically think of wind energy as being “cold” energy, and are pleasantly surprised to see how wind can be used for generating heat in the home. Another project suggests that the company offers is to have different groups split off in the classroom and then compare the respective wind turbines that they have built. They can see which ones produce the most or least electricity; which ones start up with the need of the least amount of wind power; and for very young children, which ones have the most aesthetic appeal.

There is a core curriculum that PicoTurbine has in mind for teachers to instil in their pupils. Renewable, alternative sources of energy include solar, hydroelectric, geothermal, and biomass in addition to wind-produced energy. When we use more alternative sources of energy, we decrease our nation's dependence on foreign oil supplies, which often come from nations who cannot really be called our “allies”. Alternative energy is already becoming cost effective when set against the fossil fuels that we are so reliant on currently.

PicoTurbine points out that wind farms and solar arrays are already letting their makers enjoy commercial success. In the last two decades, the cost of photovoltaic cells expressed in terms of per-watt has gone from nearly $1000 to just $4! It has been predicted by analysts that by the year 2015, the cost per watt should only be about $1 (in today's dollars). Students also need to be taught about the hidden cost of fossil fuels: pollution and environmental degradation. Air pollution from burning fossil fuels has been shown through studies to increase incidences of asthma attacks, heighten the effects of allergies, and even cause cancer. Switching over to clean, green energy found in the alternative forms would prevent air pollution and help bolster the environment.

Geothermal Power as ALTERNATIVE ENERGY

Geothermal power technologies
Geothermal power technologies (Photo credit: Wikipedia)
We should be doing everything possible to develop geothermal energy technologies. This is a largely untapped area of tremendous alternative energy potential, as it simply taps the energy being naturally produced by the Earth herself. Vast amounts of power are present below the surface crust on which we move and have our being. All we need do is tap into it and harness it.

At the Earths' core, the temperature is 60 times greater than that of water being boiled. The tremendous heat creates pressures that exert themselves only a couple of miles below us, and these pressures contain huge amounts of energy. Superheated fluids in the form of magma, which we see the power and energy of whenever there is a volcanic eruption, await our tapping. These fluids also trickle to the surface as steam and emerge from vents. We can create our own vents, and we can create our own containment chambers for the magma and convert all of this energy into electricity to light and heat our homes. In the creation of a geothermal power plant, a well would be dug where there is a good source of magma or heated fluid. Piping would be fitted down into the source, and the fluids forced to the surface to produce the needed steam. The steam would turn a turbine engine, which would generate the electricity.

There are criticisms of geothermal energy tapping which prevent it's being implemented on the large scale which it should be. Critics say that study and research to find a resourceful area is too costly and takes up too much time. Then there is more great expense needed to build a geothermal power plant, and there is no promise of the plant turning a profit. Some geothermal sites, once tapped, might be found to not produce a large enough amount of steam for the power plant to be viable or reliable. And we hear from the environmentalists who worry that bringing up magma can bring up potentially harmful materials along with it.


However, the great benefits of geothermal energy would subsume these criticisms if only we would explore it more. The fact that geothermal energy is merely the energy of the Earth herself means it does not produce any pollutants. Geothermal energy is extremely efficient—the efforts needed to channel it are minimal after a site is found and a plant is set up. Geothermal plants, furthermore, do not need to be as large as electrical plants, giant dams, or atomic energy facilities—the environment would thus be less disrupted. And, needless to say, it is an alternative form of energy—using it would mean we become that much less dependent on oil and coal. Perhaps most importantly of all—we are never, ever going to run out of geothermal energy, and it is not a commodity that would continuously become more expensive in terms of real dollars as time passes since it is ubiquitous. Geothermal energy would be, in the end, very cheap, after investigation and power plant building costs are recouped.

Are There Any Problems With SOLAR POWER?

Solar Panels All Done!
Photo  by Clownfish 
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 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 fewer 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 night time 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.

Backup Power HOME ENERGY Generator and Sustainable

English: This is a generator.
This is a generator. (Photo credit: Wikipedia)
How Well Do You Know Your Generator?

Back up power is important not only in business establishments but also in homes. This is especially so if people are experiencing man-made or natural calamities and have no way of preventing power shortage. 

During these unfortunate times, people need a source of energy to power up appliances or furniture that is important in running their household. Examples of these are heaters to warm the home in winter times, air conditioning for summer times and of course, oven and other cooking appliances for food support.

Generators are important because people have no way of determining how long the power will be down. If you want to make sure that your home will remain in a good and stable condition, you should have back up energy in order and ready to use at any time.

What are the two types of back up generators?

1. Portable generators.

This is the most economical generator that is capable of supplying back up energy. Portable generators are the most commonly used in homes or household. Appliances that needed power supply are plugged directly into this generator. This is done using wires and other cords that are applicable to the appliances.

Many of these types of generator already have advanced features like the stop or start button which people can use to be able to save up on the energy they might be needed for some time.

Portable generators also have different types depending on the volt specification that you are using in your home. You will be able to choose from 120 up to 240 volts capability. 

One of the widely used portable generators is the one that is gasoline-powered. People choose this type of generator because it costs less compared to the other type. There are even those that run on diesel or a combination of both. 

One of the downside to this is that it cannot be used for longer time. People need to refill and refuel this generator often to be able to extend its power support. In addition, diesel-powered generators are much more expensive. Although it is more efficient and with supplies that are easy to find, you may find it hard to start in cold seasons.

2. Permanent generators. 

Permanent generators are programmed to be turned on automatically within the specified time after power loss. These generators are connected to the wiring system inside the house. This is why it will start on its own whether there is nobody present in the house during a black out. It also has the capacity to shut down on its own once power is restored. 

This type of generator is powered by natural gases. The kind of gas that you are using to power some of the appliances at your home can also be used to power this generator. 

The choice of a permanent generator will depend upon how the homeowners plan to use it. If you need to power up more than the required appliances, then you can opt for permanent generators that have more than 17,000 watts capability. 

These types tend to be more expensive than portable generators. But with all its capacity, the initial money spent will be worth it once you see the kind of back up energy it will provide when you need it the most. 

Are generators hazardous? 

Portable generators are more hazardous than permanent generators. This is because they are making use of gasoline and diesel and is more capable of burning up when overheated.

This kind of generator is like your car. They tend to overheat when used extremely for a long period of time. This is why you need to check regularly and rest it for a while to prevent any damage to you, to the generator and the appliances that it is powering. 

Poisoning is also another hazard caused by portable generators. Since it is running on gas, carbon monoxide is being released into the air. According to studies, many people die of carbon monoxide poisoning. One of the reasons for this is that they are not aware that they are inhaling carbon monoxide. 



To prevent this from happening, the generator should be placed in locations where it is properly ventilated. Consider placing them outside your home where there are no chances of people to be suffocated from the carbon monoxide it gives off. 

Consider these things when you are in the process of buying a backup power for your home. Together with the necessary power supply is the need to make sure that you will encounter no health problems when you are using them already.

ALTERNATIVE ENERGY for the Home

Alternative Energy - Photo: Pixabay
The trend toward homes that are powered by alternative energy sources, ranging from wind turbines and solar collection cells to hydrogen fuel cells and biomass gases, is one that needs to continue into the 21st century and beyond. We have great need of becoming more energy independent, and not having to rely on the supplying of fossil fuels from unstable nations who are often hostile to us and our interests. 

But even beyond this factor, we as individuals need to get “off the grid” and also stop having to be so reliant on government-lobbying giant oil corporations who, while they are not really involved in any covert conspiracy, nevertheless have a stranglehold on people when it comes to heating their  homes (and if not through oil, then heat usually supplied by grid-driven electricity, another stranglehold).

As Remi Wilkinson, Senior Analyst with Carbon Free puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission, and distribution infrastructure. The power providers may have to diversify their business to make up for revenues lost through household energy microgeneration. She is referring to the conclusions by a group of UK analysts, herself included among them, who call themselves Carbon Free. Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. 

This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent. Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, microgeneration (meeting all of one's home's energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.



Carbon Free's analyses also show that energy companies themselves have jumped in on the game and seek to leverage microgeneration to their own advantage for opening up new markets for themselves. Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future. Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install.  

However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating. Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent. However, again this is initially a very expensive thing to have installed, and companies would do well to begin slashing their prices on these devices or they could find themselves losing market share.

You Can Build Your Car Powered By SOLAR, A Green Energy Source

Solar Powered Car
Photo  by borman818 
All cars are powered by gas. But with the volatility of crude oil prices and because it is not a renewable, something must be done before it is too late. Given that solar energy a green energy source is used to power a community, you can also do this on a small scale by using the same principles to build your own car.

But what do you need to make this work? A lot of things but the two most important are the solar arrays and the batteries.

The solar array is vital because this is what’s used to collect the sun’s rays and then converts this into electrical energy. There are two types to choose from in the market namely the prefabricated type and the individual kind which you set up yourself.

If you are looking for branded parts, check out either Siemens or ASE Americas that sell terrestrial grade cells and the space grade cells. The lower end model which can produce a significant amount of power is the terrestrial grade version.

Proper wiring must be done to make sure that if one of the panels is not working, your vehicle will still move. If you are worried that the voltage of the solar array should match the system voltage of your motor, you should not worry because it will still run.

We mentioned earlier that the battery is also important because this is where the solar energy will be stored. Your options for this are lead-acid, lithium-ion or nickel-cadmium. Just how many you need to buy will depend on your motor’s voltage.

When you finally have these two components, these will now have to be connected to the motor. So you know how much juice is left in your batteries, you will also need to install instrumentation similar to the heads-up display console on regular cars which tells you your speed, mileage, and gas.

Don’t forget to put a steering wheel, suspension, brakes, tires, and hubs. You may not be able to make a car that has the same features as like what you see done by one of the three US automakers but just enough to be able to drive it from one place to the next.

The only cars that use solar energy so far are the ones only used in races especially the one held in Australia from travels from the northern part of the country all the way to the south. If this has helped people realize that renewable energy is really the key to the future, the big automakers should try tapping this technology instead of relying on gasoline.


But apart from solar energy as a green energy source, biodiesel is another alternative. This is a combination of alcohol like methanol and a chemical process that separates glycerine and methyl esters (biodiesel) from fats or vegetable oils. This can also be done using corn and sugarcane.

Although these are not renewable, these are still considered as a green energy source because it is cleaner than conventional gasoline. This means you do not release harmful chemicals such as carbon monoxide into the air which causes damage to the environment. So if you can’t build a solar-powered car, consider a different fuel alternative.

Resources for ALTERNATIVE ENERGY

English: Krafla Geothermal Station.

There are many different forms in which alternative energy is available.

One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar energy power can be used for electricity, heating, and making hot water. Solar energy produces no pollution, as its input comes completely from the sun's rays. However, much more work still needs to be done in order for us to economically harness the sun's energy. For the time being, the resource is a little too conditional—storage batteries are needed to be used as backups in the evenings and on inclement days.

Wind energy has become the most-invested-in (by private investors and governments together) an alternative energy source for the time being. The great arrays of triple-bladed windmills are being placed all over as “wind farms”, to capture the motion of the wind and use its kinetic energy for conversion to mechanical or electrical energy. Of course, there is nothing new about the concept of a windmill for harnessing energy. Modern wind turbines are simply are more advanced variations on the old theme. Of course, the drawback to wind energy is...what do you do when there is a calm, still day? Needless to say, during these times the electric company kicks in for powering your home or office. Wind energy is not altogether independent.

Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. Simply put, hydroelectric energy uses the motion of water—its flow in response to gravity, which means downhill—to turn turbines which then generate electrical energy. Needless to say, water is ubiquitous; finding sources for driving hydroelectric turbines is, therefore, not much of a problem. However, hydroelectricity as a source of alternative energy can be complicated and expensive to produce. Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power.


Building a dam to store and control water's potential and kinetic energy takes quite a lot of work and operating one is complex as well, and conservationists grow concerned that it. Of course, a dam is not always needed if one is not trying to supply the electrical needs of a city or other very densely populated area. There are small run-of-river hydroelectric converters which are good for supplying neighborhoods or an individual office or home.

Probably the most underrated and under-appreciated form of alternative energy is geothermal energy, which is simply the naturally-occurring energy produced by the heating of artesian waters that are just below the earth's crust. This heat is transferred into the water from the earth's inner molten core. The water is drawn up by various different methods—there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. The purpose of drawing up the hot water is for the gathering of the steam.  The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields; it's an example of a dry stream plant.

WIND POWER as a Viable Solution to Meeting ALTERNATIVE ENERGY Needs


Although it is much less expensive to initially get hooked into the local electric company's grid than it is to set up and hook into wind turbines, in the long run, one saves money by utilizing the wind for one's energy needs—while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily—but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient. In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to “go primitive”, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment. 

Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers. In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total “green” energy systems' costs. In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what is called “net metering laws”. The rates that they are being paid by the local power companies for this energy are standard retail rates—in other words, the homeowners are actually profiting from their own energy production.


Maker Workshop - Wind Power Generator on MAKE: television from Make: on Vimeo.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn't really be a role for the federal government,” the Energy Department's Craig Stevens says. And as might be imagined, there are power companies who feel that it's unfair that they should have to pay retail rates to private individuals. “We should [only have to] pay you the wholesale rate for ... your electricity,” according to Bruce Bowen, Pacific Gas & Electric's director of regulatory policy. However, the companies seem to be more worried about losing short-term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, “It's quality power that strengthens the grid.”

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.

Why Use a HOUSE ENERGY SHIELD

We all know how dangerous lightning can be. In fact, the Discovery Channel’s Mythbusters have proven through some experiments just how dangerous having your house hit by lightning is.

Lightning, when it hits a house, actually travels through a home’s electrical system. The lightning tries to find the quickest way to the ground. It can travel through your plumbing and even through the phone.


That is just the reason why you should avoid the phone or the computer during a thunderstorm. A lightning bolt traveling through your phone into your body can actually kill you in less than a second. You might reason out that there are a lot of stories circulating about people who survive being struck by lightning. However, you have to ask yourself one question: do you feel lucky?

In the same note, you should also avoid the shower, as water plus electricity equals very bad news. 

Now that you know at least the basics of home lightning safety, let’s move on to your stuff. As said before, Lightning can travel through the house electrical system. This would be no problem for simple appliances like electric fans or light bulbs. 

Don’t breathe easy yet, because the appliances that lightning does damage are the ones containing microchips. That’s right: lightning will damage your precious high tech equipment. 

What do you do? Well, they always say that preparation is always the best thing you can do. Here are some tips:

1) Unplug all damageable appliances if you think a storm is coming – This would disconnect all the appliances from your house’s main electrical circuit and will save your stuff from being fried.

2) Get a lightning rod – Of course, almost everybody has heard about a lightning rod. This simple device attracts the lightning and diverts it from the house. This device is also grounded. This means that the lightning rod actually makes a pathway for the lightning to reach the ground as quickly as possible without damaging your equipment.

3) Get a house energy shield – This is a relatively new concept built for the sole purpose of preventing surges from frying your appliances.

House energy shields are often installed by electronics companies who specialize in accessories. If you are imagining your house covered by futuristic energy shields that deflect lightning blasts, you may have been reading too much science fiction. A house energy shield is a system provided by some companies that will protect your electrical circuit from damage in case of energy surges.

A house energy shield composes of a number of surge protectors that protect specific appliances. This prevents lightning from doing any real damage to your precious stuff.

Another component of a house energy shield is the UPS or Uninterruptible Power Supply. This piece of equipment actually provides clean power when you experience a power surge or brownout.

We all know the risks of not properly shutting down your computer. A UPS actually gives your system the proper time to shutdown before running out of power. Another problem with sudden brownouts is data loss. Don’t you just hate it when a brownout suddenly turns off your computer and you remember that you forgot to save a document you were working on?

Well, this part of the house energy shield system will allow you to save your files even when you experience a brownout. Now isn’t that just amazing?

House energy shield systems can actually be found in the internet. There are all sorts of equipments and accessories which you can use to protect your electrical system from being damaged due to unfortunate incidents.

You may also choose to buy different types of surge protection equipment and design your own house energy shield. Whatever your choice, you need to know that technology today can let you do whatever you need.

So, there you go, those are some things you may want to know about house energy shields. Remember that a thing doesn’t have to look good or even be visible in order to be effective. This is the case with a house energy shield. Sure, your house may not be enclosed in a force field, but you are protected.

And in the end, protection really does matter, right?

How to Make Your HOUSE ENERGY Efficient

One requirement of a house is that it should be comfortable to live in. Of course, many people will say that a house cannot be called that if it cannot be inhabited. In order to make a house comfortable, certain aspects of civilization are required. We need to have the benefits of technology within the house in order for us to live in it.

Let’s face it: few of us can live without the benefits of technology. Only by having the conveniences of our times available do we stand a chance at actually having comfortable lives. However, comfort does have a price. In order to have these technological conveniences we need to consume energy. Energy costs money and, as people will tell you, money is not easy to come by.


People try to find ways to save money when possible (at least, the smart ones do). An evidence of this is the way a sale can make a product immensely popular. If you take a look around you, you will probably notice that even millionaires try to save as much money as they possibly can at their level of lifestyle.

In order to save money we, of course, try not to waste any of it. Most people would rather not spend on anything that they do not need. Electricity bills have a way of making you feel cheated out of your money. People feel that electricity bills cannot be controlled, hence, they should just be paid. This is because people feel that electricity is a necessary part of life and thus, the costs of electricity cannot be reduced, only paid.

However, if you really try to look into your situation, you might be surprised to see that there are, in fact, many ways in order to make your house energy efficient. By having an energy efficient house, you can cut back on the cost of electricity and only pay for what you are really consuming.

There are many ways to make a house more energy efficient. These methods are often found by other people to be time-consuming and expensive. However, those who have chosen to employ these methods find that the savings you get by having an energy efficient house is definitely worth the effort.

One thing to consider in making an energy efficient house is material. The materials you use in building a house significantly affect the cost of heating and cooling. By choosing your materials wisely, you can have a house that does not consume much energy to maintain a comfortable temperature level.


Another thing to consider is the design. In order to make a house more energy efficient you’ll need the help of an architect. Some architects actually specialize in designing energy-efficient buildings. By going to these people, you can maximize your energy efficiency.

Of course, energy efficient houses may not look like a conventional home. In fact, these houses may even seem a little strange to those who do not realize the purpose of energy efficient designs. However, the technology today has made it possible for architects to incorporate both forma and function in their house designs. This means that you may be able to have a very aesthetically pleasing, energy efficient home.

Also, in order to have energy efficient home, you’ll need to take a look at your surroundings and see if there are any alternative energy sources available for you to use. By making use of alternative energy sources, you can significantly lower your electricity bill.

Alternative energy is also known as “free energy” to some people. This is because of the fact that these energy sources are constantly being produced through the earth’s natural processes and are thus, available for harnessing.

In order to harness those alternative energy sources for your home use, you’ll need to have some sort of mechanism or conversion device. Thankfully enough, many home alternative energy devices are now available in the market for those who want their homes to be energy efficient.

Energy efficient homes are possible, thanks to the ever evolving technology. Energy efficient homes show us that it is possible to have all the comforts offered by modern civilization without paying a very high price.

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.

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.

How to Lower HOME ENERGY Bills

We are blessed with the discovery and proper utilization of energy around us. There are several sources of energy that makes our living easier. Energy lights up our home every night, keeps us warm during cold winter, allows us to be entertained, and makes our living pleasant no matter what time of the day. And with all the other uses of energy from the moment we check our clocks in the morning to keeping us warn as we rest during the night, all of us would agree that it would be so hard to llive without it.

We can say that we have sufficient energy supply for a lifetime but that does not mean that we are not going to conserve it. After all, technology has its price. And that price is something we have to pay with cash.

And if coping with electric bill is your problem every time you see your bills, here are the ways on how to lower them:

· Provide good roof coating

A good roof coating deflects heat. And so, insuring that the roof receives a good coating would mean insuring you that your house would maintain good temperature on the inside.

· Keep your attic well ventilated.

Your attic is one of the more important parts of your house when it comes to the cooling system. The attic is your first and probably the most effective part of your house the keeps the whole house cool. But, in order for your attic to do its main purpose, make sure that it is well insulated.

Provide vents where the heat can come out during summer. Your attic door must also be sealed to ensure that the air from our house does not go through it and vice versa. The attic door can be sealed with weather strippers.

· Securing all the leaks.

Leaks contribute to high cost of home energy. Why? It is because air from your house can easily come out from these leaks. And the air from the outside can easily enter the house. Both increase the workload of your heating and cooling system.

You have to remember that air moves according to air pressure and temperature. Since the temperature of inside your house is most of the time different from the temperature outside, air moves freely from these leaks. Making sure that the leaks are sealed would mean less work on your heating and cooling system and lower electric bills.

Leaks would come from fireplaces, ducts, doors, ceilings, floors, walls, windows, plumbing penetrations, electrical outlets, fans, and vents.

· Reducing the thermostat

One degree centigrade is equivalent to 5% electric bill savings. Therefore, keeping your thermostat low will save you a lot of money. A total saving would also come from switching your thermostat further low when you are not home or if you are sleeping. The ideal temperature during winter is not higher than 68 degrees Fahrenheit.


· Limiting the use of water heater


The second largest electric consumer next to your heating and cooling system is your water heater.

When you wash you clothes, you don’t need to heat the water up. Just use the water from the faucet. This will save you by as much as 90% in washing machine energy consumption.

· Use energy efficient material around your home.

There are commercially available materials that would significantly contribute to the reduction of the cost of home energy. One of these is energy efficient windows that deflect the outside temperature (whether during winter or summer) from entering your home.

· Use your appliance efficiently

It is pretty basic for all of us to turn off televisions, air conditioning, stereos and other electronic gadgets when not using them. However, most still disregard this. The reality is; we can save a lot if we only learn how to turn them off if not in use. Also, small things such as iPod chargers, cellphone chargers, digital clocks, lights and other things that seem to consume small electric current that remain plugged day in and day out contribute to your electric bill. Making sure you unplug them would certainly lower down your monthly electric consumption.

You have the details. All you have to do is to make sure you follow them all.
