Saving Energy – Using CFLs Gets You 66% Less in Energy Cost

March 30th, 2010

For most homes in the developed countries, lighting alone accounts for 9% of the total energy requirement. For other parts of the world, it is far more than that. Thus, using cost-efficient lights can be a real life-saver, or should we say, energy-saver.

Compact fluorescent light bulbs are made to be very efficient; it uses 66% less energy than the conventional light bulbs. Just by changing from the incandescent to the CFLs could already reduce electrical consumption to 7%.

When compared to the regular light bulbs, CFLs give the same amount of luminescence for less power and while it has a higher purchase price than the incandescent, CFLs have longer lifespan (approximately 12 times than the incandescent light bulbs, about 11,000 hours), enough to save $US30 in electrical costs during the bulbs lifetime.

A US published article claimed that if a household changes 30 fixtures in their home, investing $90, the money saved in the span of five years could be anywhere from $500 to $1,500 depending on the areas electrical costs. For commercial buildings and other bigger establishments, the savings are even greater. An average CFL at 75 watts could save $22 dollars in direct energy savings per year. If that is multiplied by the number of light bulbs in a building, and include the cost of labor that could be saved from changing light bulbs, the savings could rise exponentially. True, there is a capital investment of about $2 USD per fixture; however that could be recovered in a month from money saved.

Other manufacturers of CFLs also apply titanium dioxide coating. This is because titanium dioxide is claimed to neutralize bacteria, odors and molds. Still many manufacturers of CFLs apply a luminous coating to the bulb for the purpose of luminescence after the CFL is turned off. The idea behind is that a little light could still remain, even for a short while, in cases of power failure and accidents.

Because Carbon Fluorescent lamps do not emit as much heat as the incandescent light bulbs, there is also less work for air conditioners in cooling up the space.

Surely there must be a downside.

If this could be called a downside, CFLs behave differently from the ordinary incandescent bulbs. For one, it takes longer to attain its full brightness depending on the temperature. The colder the climate is, the longer it will take for the bulb to give off full brightness. CFL also gives off the brightest light during its first use and begins to dull gradually, giving off less light as it nears the end of its life; a CFLs is expected to reduce its brightness by 20% from its original brightness on first installation. But that is just about it.

Saving energy, in almost all conceivable phases of production, is in focus today. The fuel that is currently in use, as we are all aware, is non renewable. This is why even in the field of lighting, continuous research is being done to further reduce the coefficient of energy that has to be saved.

Solid state lighting, for example, is widely used in traffic lights; although for now, using this technology to be an energy saving method for domestic consumption is still being developed as the current cost is still high. For now, saving energy through the CFLs remains to spell a definite advantage compared with incandescent light bulbs.

Is Biodiesel the Answer to Unstable Diesel Fuel Prices?

March 27th, 2010

You were probably shocked when we had the record breaking fuel prices both on gasoline and diesel in July 2008. What was more shocking was that at one point, diesel prices become more expensive than gasoline. What happened next was completely unexpected. After a couple of months, fuel prices began to drop steeply.

Still, the government took action by releasing funding on exploration of alternative forms of energy and gave incentives on those who produce crops that will be converted into fuel. While the government had been active in its campaign to become energy independent since time immemorial, it was just recently when crude prices were up, that the government had seriously taken it as a priority.

But is biodiesel the answer to unstable diesel fuel prices?

Originally, the diesel engine was designed to run on vegetable oil. But since petroleum diesel was cheaper then, vegetable oil was simply not an economical choice. But now, pump prices have driven farmers to convert their lands into biodiesel plantations. On one hand, the production of alternative fuel like biodiesel is good since its use will reduce our demand for petroleum oil. And if the demand is low, the prices will follow as well.

Since biodiesel comes from vegetable oil, it is 100% biodegradable. It does not hurt the environment. Furthermore, a wide spread use of biodiesel in the future will help solve air pollution in big cities because biodiesel help reduce carbon dioxide and other greenhouse gases emissions. The decrease on petroleum consumption has a good environmental effect.

On the other hand, experts say that while converting farmlands into biodiesel will ease the demand on petroleum products, it will drive the food prices up and may create food shortage. This is because lands that are supposed to be used in producing food are now producing fuel. Many farmers are now focused on fuel production and not on food production. Early signs of food shortage were felt right after farmers began planting more corn. It should be remembered that just recently, corn prices began to rise because of the increasing demand for biodiesel. Prices of other farm-produced fruits and vegetables rose as well.

It is important, therefore, to understand the effects of solving one problem. Does it create another problem in the process? Or will it just be a temporary solution? It is also important not to focus too much on solving a particular problem.

There are other ways to get biodiesel. Recycled restaurant grease, vegetable oil and animal fats can be used to drive your diesel engine vehicle. Other alternative forms of energy that are both efficient and do not harm the environment include solar energy, electric and even water.

No one really knows what the future of diesel fuel prices is, but one thing is for sure: if high prices happened before, it is not impossible that it will happen again. But that doesn’t mean that we focus our attention solely on producing biodiesels. We have to find and develop other forms of energy that will not compromise other important commodities. There is nothing wrong with using biodiesel but make sure that biodiesels will not become the problem that is much harder to solve.

A War Between Eating And Sustainable Power

March 24th, 2010

Today climate change is a reality that is acknowledge by even the most doubtful of skeptics. The warmer temperatures in areas where its supposed to be cool, scorching summers, and bone chilling winter have become a pattern that people cannot simply ignore.

What The War About?

Funny enough it seems that people are getting desperate and all are turning to bio-fuel like it’s the savior of all mankind. So what is bio-fuel? Bio-fuel is any gaseous, solid, or liquid material derived from biological materials. The argument ensues when people talk of the future. Bio-fuel’s raw materials are usually agricultural crops that are made to undergo fermentation and certain processes in order to produce bio-fuel.

The Problem

Who is the world’s largest oil consumer? Those with the highest number of vehicles running their roads, countries like the US, England and generally most of the European nations. When you think about it bio-fuel is made from corn, sugarcane, palm oil, vegetable oil, and etc; where do these agricultural crops come from? Third World Countries.

In Mexico they have this “tortilla crisis”. Corn which is the basic ingredient of tortilla is now sold five times the price it used to be marketed for. The reason for the inflated prices? The demand of bio-fuel in highly developed countries has severely altered the business people’s sense of profit. Why sell for a dollar when you can for 5 because the demand is now higher.

Who Suffers?

The first world countries will have to export goods from the third world countries to fuel their increasing demand for energy. The third world countries are usually tropical ones located near the equator, hence a higher crop growth of corn, and all those needed to manufacture bio-fuel; but for these countries corn is food, so is sugar cane. For the first world to survive the t poorer countries must either starve in hunger or break their back working to be able to afford the price hikes of the most basic of all commodities: food.

A Compromise

So what should we do? We need to address the problems of the environment and pollution, but it is also not right that to solve a problem we must create one. Think about it if the agricultural countries go into decline because its people can’t afford food then who will till the land to supply the giants with endless bio-fuel?

Sustainable energy is geared to sustain life, not make it harder. A proposal is in order. Since the crops needed for the production of bio-fuel can only survive in tropical countries then the governments of the more well off countries will have to invest in the agricultural countries to supply their own demand. These crops must be independent from those for local consumers. Stringent rules governing pricing and distribution must be implemented to further protect the source of the energy.

Sustainable power means the world working hand in hand to create a better way of life for the future. The road to betterment is paved with hard work and dedication. The ancient Egyptian used sails to go up and down the Nile; they were patient and they reached their destination. Let us all be patient but diligent in our quest for sustainable power to sustain life.

Solar Power for Homes: Things to Consider

March 21st, 2010

Do you think that using solar power for home is a great idea? Well, only you can answer that question. Before you embark on any project, you must have enough knowledge about it. Make sure that you do your homework first and learn everything you can about solar power. The world is suffering greatly from global warming and one of the primary causes is the use of fossil fuels to create electricity. Electricity is a necessity and because of this fact, people can’t do away with it. There is a need to look for alternative energy sources and a very good one is the use of solar power.

Before you make a decision and use solar power for your home, here are the important considerations that you should look into:

1. Where do you live? What is the weather in your area? Is it always sunny in your area or is it always raining? Are there tall trees near your house? You must answer these questions first before you start with any DIY project to create solar power for your home. If the weather is frequently sunny, then it might be a good idea to use solar power. For those with lots of trees in their yard, you need to get rid of them but this is not a very easy thing to do since trees are also very important. Local authorities might not permit you to do cut down huge tall trees. Study the weather in your area as well as your location. To use solar power, you will need the rays of the sun. Rain, clouds, and trees can block the sun’s rays and so you might end up wasting money.
2. Where do you plan to install the solar panels? You must determine the place where there is lots of sunlight all throughout the day. You can’t install the solar panels in an area where there is very little sunlight. Study your home’s surroundings. Find the perfect place where the panels can get a lot of sunlight so that you can benefit from it greatly.
3. Do you have enough knowledge on how to connect solar power into the electricity grid of your home? You can also conduct a research about it. The solar power DIY projects usually provide a complete guide on how to install the solar power to your homes. Just follow the instructions carefully to avoid committing mistakes. If you’re not that sure, you can always get an electrician to help you with the task.

Solar power can reduce your monthly electric bills by more or less 80% depending on your solar power project. In no time at all, your home can become self sufficient and you will no longer depend largely on the conventional energy sources.

Aside from that, the carbon emissions are also reduced thereby saving the environment from further damage. With a solar powered home, you can enjoy an endless electric supply that is clean, green, and fresh.

Get a solar power DIY kit now and get the needed materials. You can also ask other family members to help you out. That is, if you think that solar power is best for your home. Go through the three considerations mentioned above so that you can make an informed decision. This is the time to save money and help the environment, act now.

What to Expect from Solar Power for Homes

March 18th, 2010

Years ago, solar power was used mostly for magnifying glasses and calculators. Now, it is already possible to use solar power for homes. The energy of the sun is widely available and scientists are improving solar power systems year after year. Electricity is a necessity and life will be quite hard without it. However, the fossil fuels are depleting and electricity is expensive. The use of fossil fuels also causes damage to the Earth, thereby causing global warming and other environmental problems.

Solar power for homes is a renewable and much better energy source. Many homeowners are going green these days because they want to save money and the environment. Despite the encouragement of the government and other organizations, only 1% of the total homeowners use solar power. If you’re in the US, why don’t you visit California? You can find many solar powered homes in California.

The energy of the sun can be used in different ways to create electricity. A very good example is the use of solar generators. The generator is powered with the use of mirrors that focus and reflect sunlight. When heat is created, the generator will be powered. Photovoltaic cells are also quite popular and these are available in solar panel DIY kits. The panels are usually mounted on rooftops. When sunlight hits the photovoltaic cells, electrical charge is created which in turn power homes and offices. You can purchase the kits from online stores or even in your local area. Just shop around for the best and highly effective panel kits; these kits already include guided instructions so that you can develop a homemade solar panel.

Ordinary homeowners still find solar power too expensive and that’s the main reason why many people still opt for conventional electricity. With the modern technology of today, scientists and researchers are looking for cost effective ways to offer solar power to the public. Did you know that you can also store the energy that comes from sunlight? This is true and so you can still use solar power even when there’s no sunlight. So whether it’s nighttime or it’s raining, you can use renewable and clean energy.

Solar cookers, thermal systems, and many others are excellent alternatives but you need to know how to use them effectively. The very first step that you need to take is to determine your monthly electrical consumption. You can do this by checking your electricity bills and get the average monthly usage. You also need to consider the weather or climate in your area. After determining your electric consumption, you can now decide on the appropriate inverter. A bigger inverter can accommodate expansion in the future. For people with limited resources or budget, you can start with the simplest projects like outdoor lights and garden features. Even if you use smaller solar panels, you can still cut down your electrical bills by 20%-30%.

Try to have realistic expectations when using solar power. You can’t give up conventional electricity completely but if you can use it together with solar power, you can save a lot of money in the long run. Make this one-time investment and enjoy lasting benefits in the coming months and years. Solar power for homes is an excellent investment and you too can enjoy a greener and clean lifestyle.

Common Solar Power Systems for Homes

March 15th, 2010

Are you one of those homeowners who are dreaming of having solar powered homes? Perhaps you’re already familiar with DIY solar power kits. The idea may sound inviting however a lot of people are scared to create their own solar power system. Solar power is usually available in three kinds. You too can use any of these powers gradually.

People usually associate solar power with solar panels. But you see, solar panels are not the only source of power. You can choose among the several components known today. Take a look at these solar components that you can use at home.

1. Solar cookers – this is already a common way of using solar power. Some people may find the cooker slow in terms of performance but if you’re not rushing, you can surely cook on time. You can use the solar cooker to roast, bake, and boil. This is best suited for a small family with a maximum of 5 members. You will no longer need fuel since you will be using only sunshine. There are also no emissions or smoke.
2. Solar thermal systems – this is an ambitious system but it’s simply an update of the oldest known consumer technology. In this system, you will need solar panels. From the panels, the sun’s heat is transferred to a water tank. The water in the tank is heated. Your home can also be heated by putting some pipes. This was already available back in the 80s but it was rather expensive. Today, the thermal systems are more affordable and efficient.
3. Solar generators – many homeowners are now utilizing solar generators for alternative power. The generator makes use of photovoltaic cells where the power inverter is hooked. You can use the solar generators for your lighting system at home. The electrical power is stored in the batteries and you can use it later. By using solar generators, it would be possible to run some electrical appliances. If you have $200, you can already create the generator.

A wealth of information can be found on the net if you simply do your homework and look for useful info. By purchasing the DIY kits, you can create your own solar power system. There are also instructional materials available online that provide step by step instructions on how to create solar panels or cells. It would help a lot if you conduct a search online and read the step by step instructions there; that way, you can determine if you can carry out the project or not.

Solar power systems are not that difficult to create especially if you already have a considerable knowledge about it. All you will need to do now is to establish a workable budget so that you can start with the right project that you can afford. You can start with very simple solar power systems for your home like the solar generators. The generators are much more affordable and easy to make. After some time, you can now make more complicated plans like the thermal systems. Solar power for homes is an excellent alternative to those who want to save on electricity and help save the earth.

Don’t think twice and if you have the money to purchase the materials to make solar power systems, go for it. In the coming months, you will surely benefit from it.

Solar Power for Camping Trips

March 12th, 2010

Perhaps you’ve already heard about solar power systems. People often think that solar power is very expensive but that was years ago. Today, you can already find more affordable alternatives in order to enjoy the free energy from the sun. Many individuals love to go camping and if you’re one of them, you may as well carry a solar power system with you.

But are the systems reliable, portable enough, practical, and readily available?

RV camping can be a lot more fun if you have a solar power system with you. However, some campers simply find the whole system as unnecessary. The camping spaces are usually fully hooked up so you won’t need the system unless there is power failure. The trips are usually carefully planned and you will need to reserve for the hook-up. You can also go on an RV camping without the hookup. You can explore quiet and remote places for a couple of days. In this case, the solar power system is a must and it’s practical to have them around. Before you go camping, you must determine your electrical requirements. The camping schedule should also be appropriately chosen to make sure that there will be plenty of sunshine. The batteries can be charged using the system. Once you determine the load, you can now estimate the size of the system. Purchase the needed materials and start the installation of batteries, solar panels, and inverters. These are needed to produce the required energy.

Today, there are several solar power systems that are suitable to RVs. Shop around and you can find one that will suit your budget and needs. If you’re planning to bring electrical devices, you must calculate their energy needs so that you won’t use up all the solar energy. Try to limit the number of electrical devices you bring; besides, you’re going camping to explore nature so you can do away with the convenience of these devices.

Even if you’re camping without RVs, you can still make use of the solar power system. You can already find lightweight and portable units that generate solar power. There are flexible panels that can be carried to campsites and you will just spread them on the ground where there is direct sunlight. The generated power is enough to light a small bulb and a heater. Special backpacks collect sun’s energy and convert them into electricity which can be used to recharge your iPod, camera, and cellular phone.

Solar power is no longer limited to homes, offices, and other bog establishments. Now, it is already possible to carry solar power systems anywhere you go. Camping will be more fun if you bring a solar power system with you. Forget about conventional generators that consume fuel. You can get free electricity from the systems that are sold in the market. In the US, solar power is already recognized and many households are now using them.

Next time you plan to go camping, make sure that you bring a dependable solar power system. Plan your outing carefully and make sure that you pick the right date and day as well. If it’s sunny, you can produce more energy. Bring limited electric devices and bring only the essentials. Solar power is clean and renewable so you can stay out camping for as long as you like without worrying about energy consumption.

Out of the Ordinary: Alternative Energy Sources

March 9th, 2010

Alternative energy is often referred to as energy from a source other than the conventional fossil fuel source like oil, natural gas and coal. Alternative energy is not popularly used and is usually environmentally sound. It is also often times renewable energy. Several alternative energy sources are solar, wind, biomass, wave and tidal energy.

Population problem is not only a problem or concern about the number of people. People consume food, fresh water, wood, minerals, and energy every day. The increasing energy consumption is leading to the depletion of conventional energy sources as well as increasing pollution.

We are currently reliant on fossil fuel and other non-renewable energy. This causes great harm to out environment and will also tremendously affect future generations. Most of the current population relies on non-renewable energy source such as oil, natural gas, fossil fuel and coal.

Fossil fuels are non-renewable source of energy, it means it could run out. Also, when fossil fuels are burnt they produce the gas carbon dioxide (CO2). Carbon dioxide is known as a greenhouse gas since it traps heat from the sun and preventing it from escaping out of the Earth’s atmosphere into space. The amount of greenhouse gasses in the atmosphere is increasing. It leads to rising Earth temperature called global warming.

Alternative and renewable source of energy is therefore a necessity. Renewable energy is derived from resources that are regenerative or regenerate after consumption. For this reason, renewable energy unlike fossil fuels do not produce as many greenhouse gases.

There are several countries that are providing incentives for private sector or personal efforts to use renewable energy by giving tax incentives and subsidies. Currently, just 14 percent of the world’s energy consumption comes from renewable energy sources. But there is great potential for alternative energy. It could be large enough to cover many times the current energy consumption.

Several sources of renewable or also called alternative energy are sunlight, wind, rain, tides and geothermal heat. Wind energy comes from wind power that is generated from wind turbines. Wind energy are non-polluting energy source with low maintenance cost although the initial expense may be high.

Solar energy come from the sun’s rays that reach the Earth. Solar energy can be converted into heat and electricity. Solar energy can be converted to thermal or energy generated from heat. It can be used to heat water and heat spaces like inside greenhouses, homes and other buildings.

Biomass energy comes from plants and animal material that are usable source of energy like wood from trees, waste from other plants, manure or animal wastes. Biomass energy has numerous benefits. It uses waste materials that are usually dumped and uses up methane gas (a greenhouse gas). Fuels like ethanol can be made from biomass and uses as an alternative to petrol.

Meanwhile, hydropower makes use of the energy the water gains when it drops in elevation. That is why hydropower plants are near waterfalls or dams. Hydropower has been used since the start of the electric age but unfortunately the value of this energy has not yet been developed and maximized.

Another alternative energy source would be geothermal energy or energy derived from the underwater heat the world is emitting. Geothermal power plants are unaffected of changing weather conditions. It is also price competitive and helps the people’s reliance on fossil fuels lessen.

These only show that we can choose alternative ways on using energy to lessesn its negative impact on our environment. Alternative energy sources provide us a choice for a bright and healthy future. It may something be out of the ordinary but it can also be useful.

Solar Power in the US

March 6th, 2010

Sunlight contains energy and if you can capture it using a special gadget, you can turn it into electricity. For many years, solar power was always overlooked. But now that the world is becoming warmer, the sources of fossil fuels are depleting, and the cost of electricity is continuously rising, many people now realize the importance of solar power.

With solar power, you will no longer have to worry about electricity once you’ve installed the solar power system. Aside from that, you will get clean and renewable energy. When you install a solar power system, you’re able to hit two birds with one stone – you’re able to save the earth and you can save a lot of money in the coming years. The system can last for about twenty years and that’s like a lifetime already. With proper care and maintenance, the system might reach thirty years of service.

In the US, solar power is gaining popularity. Years ago, it would have been impossible to use solar power in homes because it was too expensive. But thanks to modern technology, many homeowners in the US as well as businesses now make use of solar energy. Power bills can surely be reduced thereby saving the environment and the pockets of homeowners or businesspersons.

Some places in the US enjoy a lot of sunlight particularly Los Angeles California. There are so many solar power systems available today and solar panels are just one of them. Despite the many benefits of solar power, have you ever wondered why very few people use it? At this point, experts claim that solar power is still inefficient. To generate more electricity, then larger solar panels are needed which are quite bulky. Just imagine putting a large and ugly panel on your rooftop which can destroy your home’s overall beauty? Ready made solar panels are quite costly that ranges from $35,000 – $250,000 depending on the size.

Scientists are still conducting researches and at present, solar power is said to be more efficient now unlike many years ago. Drastic changes were made thereby improving the solar panel’s price and appearance. With the invention of the photovoltaic cells, solar power was greatly improved. The cells will be placed on steel substrate to capture sunlight and the energy will be stored within the battery. The photovoltaic panels contain n layers of cells thereby increasing its efficiency. These new panels make use of the ‘amorphous silicon thin alloy technology’. Through this technology, the cells are not bulky anymore and highly efficient. With stylish photovoltaic panels, your house or office will still look pleasant eve with the panel on top.

Aside from the cell, photovoltaic shingles were also invented. Basically, the shingles modified solar panels. If you don’t want to use bulky solar panels, this is an excellent choice because of its aesthetic and convenient design. The photovoltaic shingles look like ordinary shingles and are colored black.

The photovoltaic cells and shingles have definitely enhanced the solar power technology. Who knows? Perhaps in the future, experts and scientists can now develop smaller cells, panels, etc. Check out LA and see the solar powered homes there. You can now start calculating your home’s electrical requirements so that you can determine the right size of the power system. Start with a small project and work your way up but if you can afford to pay for ready-made ones, go ahead.

Saving Energy – Learning from Californians

March 3rd, 2010

The recent electricity problems that happened in California made them rethink the manner in which energy is used and saved. The effort conducted at conserving this resource made many people to reevaluate their choices on energy consumption. The truth is there is really not that much energy to waste. The examples made by Californians about thoughtful ways where less should suffice. The following energy saving suggestions were part of smart choices that was made.

1.Refrigerators that were manufactured 20 or 30 years ago gives off 1,100 lbs. of CO2 emissions per year. Keeping an old model refrigerator increases your monthly energy bill by as much as $80. The newer models are energy efficient.

Manufacturers print this on the fridge. But even the newer ones could not save you as much energy as it should if it is positioned near heat radiating appliances like the dishwasher or ovens and stoves. This is why, to allow for saving energy, interior designers and architects make it a point to have separate areas for cooling and heating appliances.

If you maintain the temperature of the refrigerator at the right level, you can save as much as 25% on energy consumption than when the temperature higher than what is required.

2.Air drying your dishes will save energy instead of putting them inside the dishwasher.

3.Clothes dyers spend much energy that whenever possible, air or sun drying should be done. Washing in cold water also saves energy by 75%. This could also prevent the dryer from emitting 500 lbs. a year in carbon gasses.

4.More than 50 degrees of heat is lost whenever you open the oven during cooking, Study the cooking instructions and preheat the oven as required. Open the oven only when needed.

5.While shades and curtains are good practices to regulate the temperature and let the light in a room, adding e-films gets you far in saving energy during heating and air-conditioning the space. Storm windows are good energy saving devices so are high performance double paned windows.

6.Extra work will be required from your heater or air-conditioner when you have air leaks and drafts around your house. Sealing the home is one of the cheapest ways to conserve energy. Limiting the use of ventilating fans and closing the damper in the fireplace when not in use keep the desired temperature inside the home.

7.In many parts of the country, ceiling fans are enough to cool home that is well insulated. If using air-conditioners is a must, planting shrubs and trees on the surrounding areas of the room to be cooled will you give you as much as 10% savings on energy consumption.

8.Trellises, overhangs and especially trees help so much in cooling the home during the summer months. It also serves as a good wind breaker during winter.

9.Unplug appliances that are not in use. Keeping appliances plugged in and keeping them on standby modes consume about 10% of the power it requires when in operation.

Buy only stuffs that are really necessary. The seemingly innocent stuffs that fills our home was manufactured using energy that translates to greenhouse gas emissions from the sorting of raw materials to manufacture and the freight it required to be delivered to the stores and eventually to the end user.
