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.

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.

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. 

Windcraft - Photo by acidpix 
Wind energy has become the most-invested-in (by private investors and governments together) 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.

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.

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.

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.

HOME ENERGY Consumption

5 Ways to Cut Down Your Home Energy Consumption

If you have been receiving high electric bill month after month, then be alarmed. You might be using your appliances more what your require them.

Normally, a regular American household would consume between $1500 and $2000 on electric bills alone. If you happen to fall between these figures, then you can consider yourself as a regular homeowner that uses electricity that is not really needed. Why? One reason: You don’t need to spend as much as $2000 a year for energy. And you don’t even have to spend more than that either. You see, a regular household that spends at this amount often wastes power and of course money. And with an increased electric rate, the bills will go even higher.

Want to do some changes?

Then, here are the things you should know. The 5 ways to cut down your home energy consumption:

1.  The thermostat control

When you want your room to be super cool because you are sweating from the inside, you simple don’t turn the thermostat super low. Remember this: the thermostat will not run as quickly as you want. It will run on the same level all throughout until it reaches the temperature you set. So whether you gradually switch your thermostat low or instantly set it on its lowest, you will receive the same result. The main difference is, you only spend more energy when you think you can get your room to cool quickly if you set your thermostat low.

Think of it this way: You are driving at 5mph when you suddenly shift to 5th gear. What you will get? More pressure on the pedal with lesser speed gained. In other words, you waste so much gas but do not instant speed.

Also, to further cut down your electric bill, you can set the thermostat several degrees lower when you are out or when you sleep.

2.  Several small consumptions add up

Your iPod charger, cellphone charger, and other chargers that are plugged 24/7 can cost you additional digits on your electric bill. This also goes to your night-lights that are switched on all day, all night. Also, your digital clocks and pots that are plugged since brought to the house consume high home energy. The computer monitor that is left on the whole day adds up to your electric bill. All these contribute to the cost you pay for your electric bill. Imagine this: these things that you think do not contribute so much adds 5% on your electric bill.

3.  The cool way

You don’t need a warm water to wash your clothes. Oh, you think that warm water kills germs on your clothes. Well, you don’t need them. Settle for cold water. You can save as much as 90% on your washing machine’s electric consumption of you don’t use water heater.

4.  Sealing the leaks

Leaks can come from doors, sills, windows, cracks on the walls, and joints. And making sure that these leaks are given proper attention would yield to saving in the long run. Make sure that your doors are closed properly. If there are spaces, seal them. This goes with all the doors from garage doors, exterior doors, operable windows, to door of the attic. Use sealants such as weather strippers. Windows should also be free from leaks. Cover them with plastic coating so that the heat will be contained inside your home. Cracks on the walls should also be sealed. Regular sealants will instantly do the jobs. The reason for doing this is that you need to keep the heat contained inside your home so that the heating system would not need to do extra work due to heat loss from these leaks.

5.  Keep them small

If you are dinning alone and would want to warm up left over straight from your fridge, do not use large pots or ovens. Instead, settle for small pots and microwave. Small pots require less heat while microware has use lesser power than oven. Small burner instead of large burner is more ideal in preparing meals for two reason: one, it consumes less electricity, and two, it your air conditioning would not work double time cooling down the room. According to the American Council for an Energy-Efficient Economy, you can save from 30 to 40% on energy cost if you follow these ways.

Fall HOME ENERGY Savings Tips: Preparing for the Winter

Whether you like it or not and whether you come prepared or not, winter is coming. So better not sit on your couch and wait for it to come like a dooms day, move and be prepared! 

Winter means one thing: cold air. But for those who are conscious enough to notice, winter means larger electric bills. Yes, it is true. Aside from summer, winter is the season of the year where your electric bills skyrocket to digits that cost you financial burden. Why? Because we need to warm our home. Our home should have the right temperature to give us comfort. And the modern way to do it is by turning on our heating system. This consumes the biggest portion of our electric bill. 

Fortunately, we have the whole Fall to prepare for it. And to prepare for it means that we must have the right tool and proper information on how to save during the coming season. 

English: Photo of a stone fireplace.

The fireplace – Getting our fireplace ready will certainly yield to better savings; and fall is the best time to clean and repair our fireplace. Make sure that the dumper is tightly sealed when not using them. A small space would let the cold air rush in and send the warm air out. If you were using electric heating system, an opening on the fireplace would mean bigger work to maintain the place warm. Let professional contractor to do the proper maintenance. They are certainly more capable in securing your fireplace. 

When you decide to use the fireplace, you can turn down your heater. This will save you as much as 8% on heating cost. 

The furnace – The furnace will work extra effort if the filter is full of dirt. This will equate to energy waste since the furnace will consume more power against the service it brings. To avoid this, make sure that your filter is clean. The owner’s manual will tell you how to clean the filter. A clean filter will let you breath clean air around your house. A clean filter saves you 5% on heating cost. 

The duct – Small leaks on duct will certainly result to lost heat so make sure that this is regularly checked. Usually ducts are located on unheated places. This is another reason why heat is lost. Insulate the ducts by wrapping it with R-6 or higher fiberglass. Never use cloth-backed tapes. You can also wrap them with UL-approved metallic or plastic tapes and mastic sealants. The note that leaking ducts work 30% more on your heating system so make sure they are sealed and secured. 

The solar heat – You need not have solar panels on your roof to use the sun as the source of heat. All you have to do is use open your drapes during the day to warn your room without using electricity. Just close them at night to keep the warn air inside. Reduction of the use of heating system during the day will let you cut as much as 10% on your electric consumption

The openings – Openings on your doors, windows, joints and sills will let the cold air outside to go in and the warm air from the inside to go out. Make sure that these openings are sealed with either sealant or weatherstripping. It will help reduce the work of the heating system immensely. 

The thermostat – A programmable thermostat or a centralized heating system will let you save on the heating cost. The programmable thermostat will let you set your desired room temperature on a specific period of the day. This is much useful if you are leaving your home or are going to sleep overnight. The centralized heating system on the other hand will give you the ultimate control on the temperature of every room. These 2 will let you decide how warm a room could be. One interesting thing to note is that a centigrade lower on your heating system will let your save uas much as 5% on your heating cost. 

The water heater – Households can set the heating system between 120 to 140 degrees Fahrenheit. This range is ideal on both mobile homes and regular homes.

Geothermal as a GREEN ENERGY Source

We have the technology to do a lot of things and one of these is to tap the earth’s energy. This is exactly what we do when we decide to use geothermal which happens to be a green energy source.

Geothermal energy is energy obtained by tapping heat from the earth itself. This comes from magma and the radioactive decay of uranium, thorium, and potassium.

The downside to geothermal energy is the fact that it is expensive to build. On the other hand, because the earth's crust continuously decays replenishing the heat, it is still a renewable source of energy.

English: Diagram of EGS with numeric labels. 1...

There are three types of geothermal plants around. These are namely dry steam, flash, and binary.

Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator.

Flash plants take on water at temperatures over 200 °C, out of the ground, and allows it to boil as it rises to the surface then separates the steam phase in steam/water separators which runs the steam through a turbine to generate electricity.

Last, you have binary plants. Here, hot water flows through heat exchangers and that boiling organic fluid is what spins the turbine.

Once power is generated, the condensed steam and remaining geothermal fluid from all three types of plants are injected back into the hot rock to pick up more heat.

Geothermal plants are used operational in different parts of the globe. These are usually located in geologically unstable parts of the planet. You can see some in Chile, Iceland, New Zealand, United States, the Philippines and Italy. At home, two most prominent areas for this are in the Yellowstone basin and in northern California.

Aside from digging deep into the earth, there are some who believe we can generate power from hot dry rocks. You have to dig 3 kilometers deep are drilled into the earth first to find these hot underground radiogenic granite rocks. Right now, some Australia companies are exploring this technology.

If you were to compare the amount of energy collected from geothermal to solar, you still get more from the sun. Despite that, people should still use it since solar energy cannot be harnessed when the clouds block the sun’s rays from reaching the solar panels.

Geothermal energy is a green energy source just like wind, hydropower and biofuel because it is a renewable. By maximizing its potential, we don’t have to worry about the price of oil in the world market when it hit more than $110 a barrel and is now under $40 in the world market.

But that is not the only thing we should be concerned about. We should also do our best to protect the environment given that coal fired and nuclear power plants produce harmful gases and radioactive waste that may cause to people and the surrounding areas.

Everyone knows that our planet has changed due to global warming. We learned our lessons from Chernobyl and Three Mile Island but this does not mean it may not happen again.

For us to do our share to protect the environment now and for generations to come, we have to promote alternative energy and geothermal as a green energy source is just one of many that is currently available.

BRICK STONE Home Energy Efficient

How Can Brick Stone Make Your Home Energy Efficient?

A home that’s energy-efficient is actually healthier and cost effective. Energy efficiency modifications in your home can eliminate or at least lessen the poor quality of air that’s brought in by various weather conditions. One way to make your home energy efficient is to pay attention to the building materials and to the house design. 
English: The Braden energy efficient farm house

In Australia, bricks have long been recognized as commonly chosen building materials. In fact, nearly 90% of the built houses in the said place are constructed using bricks. Because of the campaign to decrease energy consumption in its entire forms, there are building regulations these days that require the newly built houses to be more energy efficient. Well there are some things you need to know in order to come up with an informed choice. 

Think about the amount of energy that’s usually consumed in your home. Maybe, you’ll be surprised to find out that a large part of the home energy is used up in cooling and heating. Cooking and lighting, even when put together, comprise only a few percent. Hence, anything which can help lessen the cooling and heating bills of your home will be a good investment, right? But the question is, do you think it is possible to cut down cooling and heating energy consumption while keeping up a practical thermal comfort inside your home?  It is in this case that passive design comes into play. 

Passive design handles the energy coming from the sun to improve the house’s cooling and heating in a natural way. There are actually four major principles in passive design. These are orientation, insulation and thermal mass. 

·  Orientation. The huge glass portion in the north part allows the low winter sun in. And to block the high summer sun, simple shading like eaves is applied. 

·  Ventilation.  When the crest of summer time has already passed, air is permitted to get in and go out of the house in order to make it cool in a natural manner. To optimize cross ventilation, the either side of the building or the house have generous openings with almost negligible internal obstructions. 

·  Insulation. The insulation in the wall and ceiling serves as the obstacle to heat transportation. Insulation efficiency can be calculated by means of its R-value but it doesn’t present the whole issue. Various walls may have the same R-value but may not work the same. 

·  Thermal Mass. Wall materials that are dense and heavy, like bricks, suck up heat and hamper its conveyance through the walls. Through these, temperature changes become moderate and the heat absorption during summer is significantly hampered. Compared to brick walls, the lightweight materials have very low thermal mass. And because of this thermal mass, brick walls turn out to be more capable of moderating home temperature even if they have similar R-values. 

Now come to think of thermal mass and consider brick stone. The first two techniques in the passive design, which are orientation and ventilation, need to be set up into the house. And your home material preference has a major effect on the quantity of thermal mass in a house or a building. One of the simplest and most economical ways to put up thermal mass is through bricks. Those bricks that are made from clay contain very high thermal mass. They are available to make your home well ventilated, comfortable and more energy efficient. 

There is a research proving the idea that Brick stone homes are energy efficient. The said research has revealed that a large part of the heat is bounced back to the outside environment via the brick’s exterior panel.  Another conclusion that came out is that in summertime, the temperature inside a home that’s constructed from bricks remained favorable and comfortable in spite of the changing temperature outside.

The US Department of Energy stated that thermal mass stores up heat by means of converting its temperature. It can be achieved by storing heat coming from a warm room or by means or transforming direct solar radiation into heat. And since brick stone has more thermal mass than other building lightweight materials, it is a very useful element that can be used up in making your home more energy efficient. 

To sum up, brick is a very simple and inexpensive technique in putting up thermal mass in your next home. Therefore a brick stone home is more energy efficient than those that are made from other materials.

Biofuels are produced by converting organic matter into fuel for powering our society. These biofuels are an alternative energy source to the fossil fuels that we currently depend upon. The biofuels umbrella includes under its aegis ethanol and derivatives of plants such as sugar cane, as well aS vegetable and corn oils. However, not all ethanol products are designed to be used as a kind of gasoline. The International Energy Agency (IEA) tells us that ethanol could comprise up to 10 percent of the world's usable gasoline by 2025, and up to 30 percent by 2050. Today, the percentage figure is two percent.

However, we have a long way to go to refine and make economic and practical these biofuels that we are researching. A study by Oregon State University proves this. We have yet to develop biofuels that are as energy efficient as gasoline made from petroleum. Energy efficiency is the measure of how much usable energy for our needed purposes is derived from a certain amount of input energy. (Nothing that mankind has ever used has derived more energy from output than from what the needed input was. What has always been important is the conversion—the end-product energy is what is useful for our needs, while the input energy is just the effort it takes to produce the end-product.) The OSU study found corn-derived ethanol to be only 20% energy efficient (gasoline made from petroleum is 75% energy efficient). Biodiesel fuel was recorded at 69% energy efficiency. However, the study did turn up one positive: cellulose-derived ethanol was charted at 85% efficiency, which is even higher than that of the fantastically efficient nuclear energy.

Recently, oil futures have been down on the New York Stock Exchange, as analysts from several different countries are predicting a surge in biofuel availability which would offset the value of oil, dropping crude oil prices on the international market to $40 per barrel or thereabouts.  The Chicago Stock Exchange has a grain futures market which is starting to “steal” investment activity away from the oil futures in NY, as investors are definitely expecting better profitability to start coming from biofuels. Indeed, it is predicted by a consensus of analysts that biofuels shall be supplying seven percent of the entire world's transportation fuels by the year 2030. One certain energy markets analyst has said, growth in demand for diesel and gasoline may slow down dramatically, if the government subsidizes firms distributing biofuels and further pushes to promote the use of eco-friendly fuel.

There are several nations which are seriously involved in the development of biofuels.

There is Brazil, which happens to be the world's biggest producer of ethanols derived from sugars. It produces approximately three and a half billion gallons of ethanol per year.

The United States, while being the world's greatest oil-guzzler, is already the second largest producer of biofuels behind Brazil.

The European Union's biodiesel production capacity is now in excess of four million (British) tonnes. 80 percent of the EU's biodiesel fuels are derived from rapeseed oil; soybean oil and a marginal quantity of palm oil comprise the other 20 percent.

Home ENERGY Audit

Home Energy Audit: Checking Out the Parts of the Home

Going about a home energy audit is one smart way of cutting the utility bills that you pay for at the end of every month. Many people tend to forget about the parts of their homes that might be causing the rise in the home energy consumption. One fact that you must learn to take note of is that the home appliances that you possess, although they are switched off and not in use, still consume energy because of the phantom loads that they create. Examples of these are the VCRs, stereo components, microwave oven, toasters, and the stoves.

Although they are turned off, they still consume energy. How much more when you total their consumptions in a day and then for the entire month? Likewise, the remote controlled devices are always put on a ready mode. Such state of readiness also consumes home energy. Apart from these concerns, the parts of the home contribute to the escalating home energy consumptions. Among these are the attics, fireplaces, and the rest of the less obvious parts of the house.

The General Purpose of the Home Energy Audit

Why is a home energy audit recommended by the experts? What is this process devoted for? For everyone’s clear understanding, the ultimate purpose of the home energy audit is the making possible of the efficiency in the energy utilized in the home. When the home energy used is maximized and securely utilized, there will be the most possible reduction of the utility bills today and the succeeding years to come. 

A home energy audit will work best for homeowners who are confronted with very large electric bills. In fact, conducting the needed home energy audit will let you save thousands of dollars in the upcoming years. Stop dwelling on the windows and doors you have at home for they are obvious spots that let you lose much home energy. Why not look into the less obvious spots like the attic, the ceilings, and the fireplace?

Most homeowners put away their unused things and keep them in the attic. Sure, the attic is a great place to store your junked stuffs. But then didn’t you ever glance at your attic and consider the renovation of it so that there will be proper insulation in there? You may indeed throw out big bucks for its improvement but it will do your attic good, so to speak. The attic must be installed with open air vents so as to keep up a good air circulation. When there is no proper air circulation in the attic, the utmost tendency is for the roofing and the stored stuff in the attic to get destroyed. 

Now take into consideration the ceiling you’ve got at home. It must have enough insulation so that the home energy will be kept from escaping from it and to go upwards to the attic. The easiest way for heat to transfer into the attic is through a hole in the ceiling. 

Also take a good look at the fireplace. When the concern of regulating and controlling the temperature inside the home comes in, the fireplace is the most difficult spot to cover. As the design of the fireplace is concerned, it is particularly aimed at moving the smoke out of the interior environment of the home. 

The process is known as the propulsion of the heat. But then the main problem is that whenever the fireplace is not in use, it still goes on with the propulsion of the heat towards the exterior borders of your home. 

When dealing with a fireplace, you should bear in your mind that the flue must always be kept closed when it is not being used. But if you intend to have it open, simply turn off the heater inside your home since it will come out of the vents then cross the room, and then right into the fireplace the heat will be blown out. For some logical reasons, such situation will just cause you a nightmare in terms of the electrical bills that will confront you.

If you are serious with your intention of cutting back your home energy costs, a home energy audit will be best.

Is biomass a green energy source? According to experts, yes it is. In fact, it is one of the three main areas of bioenergy.

Also called Elephant Grass it is grown as a fuel for a mini powerstation in the area. Eccleshall Biomass Farming for Energy is a 2 megawatt power plant that will generate electricity using energy crops and provides 2,000 homes with electricity.

But what is bioenergy? Well, it is a process by which organic material such as animal waste, plants and wood are used to generate electricity, produce heat and also aid in the production of biofuels.

In the case of biomass, hot air or water is generated to produce electricity. This is done through direct combustion and is considered the simplest and most common method of generating energy from biomass.

Aside from generating electricity, biomass can be used for hot air production so you can keep a place warm. For this to work, biomass has to be combusted in a furnace where it heats either water or air. Speaking of water, this enables you to have warm water so you can take a shower. In short, biomass in itself can also be used in a small scale as a heating system.

Since you can generate electricity and heat, some people have been able to combine the two which is known as combined heat and power or CHP. Something that many consider to be good as you use one energy source for two purposes.

If you are able to compare the amount of electricity generated between biomass and let’s say solar energy, you will notice that biomass produces more because the energy in plants is already captured and stored.

You don’t have to collect it first which is what happens with solar or even wind energy since this is manufactured technology. It is readily available unlike the other two which is totally dependent on the weather.

Another is the fact that you can even use organic waste to product electricity. No other green energy source can do that and by using this extensively, any government can save money because you don’t have to spend money to dispose of the waste and you will no longer depend on foreign oil that much to power your plants.

The downside to biomass is that because you have to burn waste and other organic materials to product power, you add to the pollution which is already in the atmosphere. But this can be offset of course by planting more crops which we know helps reduce the amount of carbon dioxide in the atmosphere.

You will also have to shell out a lot of money initially for the costs of labor, the transport of these fuels and how these should be stored.

Biomass uses renewable natural resources which is why it is considered a green energy source. This means that we have an endless supply of it around just like the power of the sun or the wind which flows from the ocean. The challenge is to find suitable land that has a sufficient water supply so these will be able to grow.

This means that in areas where water is not that abundant, you cannot rely on biomass technology to generate power. When that happens, you use other means and one good example given the right geographical location is wave energy which is the process of generating power from the water.

There is a way to generate power without causing harm to the environment. We have the technology and the green energy sources. We just need to muster the willingness to make it happen.
