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.

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.

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.

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.
