Hello, welcome to the Solar Cost! This blog provides useful information related to the solar energy and its application. Fossil energy is not renewable and there is no better time than right now to switch to the solar energy, especially with the ever increasing costs of living. Compared to the fossil fuel, solar costs nothing except for the solar kits and the installation cost.

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.
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.
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.
Saving energy and saving money should not be your sole responsibility as parents. Your kids must also learn to contribute in keeping the electric bills down. This way, your effort will not get wasted and at the same time, your kids will learn good values while growing up.
Because teaching your kids to be energy efficient requires some effort, here are easy to follow suggestions you can do:
Education
Teaching your kids the importance of saving energy should be your first goal. Take note that making them understand the value of being energy efficient is more effective than enumerating the ways to save energy and leaving it at that. Teach them how conserving energy helps the environment. Tell them stories or read educational books about the importance of energy.
Lead by example
You know very well that kids tend to follow what elders do. Practice what you preach. You may have listed and posted a litany of things-to-do to conserve energy but if you don’t follow them yourself, you cannot expect your kids to follow it too. Do not just tell them to turn the lights off before leaving their room; show them by always turning the lights off every time you leave a room in your house. Education and leading by example are a good combination if you want to make good habits stick.
Make it fun
Find educational materials where your kids will learn the value of conserving energy as well as the ways on how to save it. Computer software, educational websites, books and television shows that educate and entertain kids would really make a difference on how well they will respond. This is especially applicable to kids from 5 to 10 years old.
Get your kids involved
Family activities should not limit to eating, playing and entertainment. Chores can also be a good way to bond with your kids. Manually wash the car, water the plants, clean the table, wash the dishes, clean the house etc. These are some of the things you can do with your kids while conserving energy.
Teach your kids according to their age
Kids of different ages have different attitude on things around them. If your 5-year son doesn’t know how to turn off the lights before leaving the room, all you need to do is to talk to him well about its importance and showing him that you practice what you teach.
Your 10-year old daughter may require different approach like showing her your electric bill and explaining to her that it will greatly help if she will change her bad habits. You are teaching your 5-year old good habits while you are teaching and emphasizing your 10-year old good habits and responsibility.
Same thing applies to kids of different ages. The point is, make sure that you teach your kids proper ways to conserve energy using an approach suited to their ages.
Energy saving tips for kids:
1-Turn off the water while brushing your teeth.
2-Always turn the lights off before leaving the room.
3-Turn the computer off after use.
4-Do not hold the refrigerator open.
5-Unplug unnecessary appliance.
6-Use natural light if possible.
Saving energy is not so hard if your kids are involved. And just like any family activities you do, energy conservation should be fun, educational and driven by good motivation.
Who wouldn’t want to get a lifetime supply of free electricity? Well, that can be realized only if you install a dependable and durable solar power system. Solar power is free but only after the installation of the power system. Conventional electricity comes from the burning of fossil fuels that in turn contribute to global warming. The effects of global warming are quite evident nowadays. Many people are now interested in saving the environment to prevent the devastating effects of pollution. One way to decrease pollution and environmental concerns is through the use of solar power.
Solar power can be used in different ways especially in households. You can use it for lighting, for cooking, for heating the house, and many others. Utility bills are very expensive and you can cut it down by installing a solar power system. The system has solar panels that collect sunlight and converts the energy of the sun into electricity. You can readily use the electricity or it can be stored in the batteries.
The sun’s raw energy can’t be used to power homes and it needs to be converted first through the inverter. If you have a solar powered house, you can make use of renewable and clean electricity. Even if you can’t cut off your traditional electrical supply, you will be able to reduce the consumption thereby helping the environment. Electricity is generated by burning fossil fuels that contribute to pollution and global warming. The supply of fossil fuels is also decreasing and the world might face electricity shortage soon if they don’t conserve energy. It would be best to start using solar power now.
Through the efforts of SEPA (Solar Electric Power Association), the public is made aware of the many benefits of solar powered homes. This is the best time to make substantial efforts to save the environment. Solar power can’t possibly replace conventional energy sources today but who knows. If the technological advancements can help in the enhancement of solar power systems, perhaps in the near future the whole world can go green.
Pollution is widespread and it poses a great threat to the world. By reducing traditional electricity consumption, you can also lessen pollution. Solar power can provide clean, renewable, and free electricity. It doesn’t produce harmful emissions. You can enjoy free electricity as long as the system is working properly and as long as the sun rises.
The solar power systems are not that expensive these days. In fact, you already get a solar power kit for as low as $200. Still, the large solar panels are expensive. The federal government in the US offers incentives, loans, grants, rebates, and other financial options to help homeowners in installing a power system. Take advantage of these financial options so that you can start helping the environment.
Solar power systems can serve your home for about twenty years when properly maintained. It’s like an entire lifetime if you start now. If every home around the world patronizes solar power, global warming can be greatly reduced and Mother Nature can heal herself. Try to learn more about solar power and if you can afford to install a system at home or in the office, don’t hesitate because you’re doing the world a favor and you also get a lot of benefits.
People installing solar panels in the United States are allowed to receive up to 30% of the solar installation cost in the form of tax credits. This is not the end of the sweet offer as two senators have proposed a new bill that would offer rebates to cover up to 50% the cost of 10 million new solar arrays and 200,000 solar water heating systems.
The “10 Million Solar Roofs and 10 Million Gallons of Solar Water-Heating Act of 2010″ is proposed following the Million Solar Roofs program launched by California’s Governor Arnold Schwarzenegger that has established the state as a solar energy leader in the United States.
Jeff Wolfe, co-founder and CEO of the Vermont-based solar company groSolar, said the bill would “help make America energy-independent while creating many thousands of good-paying jobs,” according to a news release published by the solar trade association.

Many years ago, it would have been impossible to use solar power at home because the installation cost was too expensive. However, with the advancements in technology, households and offices can now make use of solar power because the solar power system kits are more affordable. Homes that have solar power systems can expect added market value and aside from that, you can expect a significant decrease in your electric bills.
How much is the cost for installing a solar power system? If you live in the US, you can take advantage of the financial incentives offered by the government to make the installation cost more affordable.
Before you finally decide to use a solar power system for your home, you need to calculate your electrical needs. Determine the kWh that your home consumes in a month and in a year. You can find such info on the monthly utility bill. Study the bills so that you will now which months have the greatest consumption and the months with the least consumption.
New homeowners can compute their electricity consumption by checking your electrical appliances. Just estimate the load based on your appliances, lights, and other things that consume electricity.
Electrically bills are showing a continuous upward trend and so many people are now complaining about their monthly bills. A very good answer is solar power. Where do you live? The place where the home or establishment is situated is a primary consideration. In the US, you can install the solar power system in any of the states. If you can find solar contractors locally, you can seek their help to determine the appropriate size of the system.
1-5 kW of solar power system is already enough to meet your home’s electricity needs. You don’t need to cut off your existing power supply in order to utilize solar power. You can simply use the photovoltaic systems as a supplement. This step alone can already reduce your monthly bills. Do you have enough space for the photovoltaic system? For every square foot, you can already yield 10 watts; you can start your computation from there.
Here’s how you can compute the total cost: the retail price of the system plus the cost of building permits, less federal tax credit of $2,000 and the local or state rebates/tax credit, less other incentives equals to your net investment. You can shop around for the best and most suitable solar power system in the market. If you live in California, it will be easier to find local sellers of solar power systems because many homes in the city are already solar powered. For those living in other places, it would be easier to shop online. There are lots of online stores that offer photovoltaic systems but try to stick with the reputable and established manufacturers that offer 10-15 years of warranty.
Instead of paying for expensive monthly utility bills, why not invest in solar power systems? The total cost will depend on the size of the system, your location, and other related factors. Inquire at a local agency about the incentives offered by your state so that you can also save money. It’s a wise decision to invest in photovoltaic systems because you’ll benefit greatly in the succeeding years. Shop around now and determine your available options.
Wouldn’t it be great if we can produce our own green energy source? If we can do that, we don’t have to pay electrical bills or gasoline anymore for our cars. While we can buy some of the equipment, the rest will have to be done on our own.
Take solar or wind energy for example. We already know how to harness and make it. If you want to make one, do some research online and then set up the system yourself.
To have solar energy, you will need to buy an inverter, battery, charge controller, solar panels, some wires and support structure. The only difference with wind energy is that you need a fan. Once you have everything you need, you can put it all together.
If you are not skillful, you will be happy to know that some companies sell the entire system. By buying it from them and having it installed by their experts, you are sure that there won’t be any problems the moment you switch it on.
There is one more thing you need before you can use one or the two green energy sources. Before you buy the materials or the system, make sure you have a flat area that is about a hundred square feet or so because it occupies a lot of space.
For those who don’t have the space or the budget to use these two energy sources, another option is to create your own biofuels.
Biofuels are used in many countries and they get it from harvesting corn, sugar and other crops. Luckily, you don’t need a farm to produce it because you can also make your own using some recycled waste.
A good example of this is vegetable oil which we use for cooking. To turn this into a biofuel, we first filter it by warming up the liquid and then filtering this with a coffee filter. The next step is to remove the water also by boiling it again at 100 degrees for a short period of time.
We need to know the amount of lye present in the vegetable oil and we do this by a process known as titration. When we are done with that, we now mix sodium hydroxide to produce sodium methoxide.
The process of converting used vegetable oil before it becomes a biofuel takes quite awhile and it must be heated the entire time. This is done so the fuel we produce is pure and only when this is achieved that we give it time to cool.
Just how much biofuel we make after all the work varies but you will have an idea of how much you have produced since this is the one you see floating at the top. If there is still some glycerin present, filter it again. From there, you already have your own backyard biofuel which you can use and even sell to those who are just as concerned with the environment as you are.
By making our own green energy sources, we make ourselves less dependent on gasoline in its various forms to power our heater, home or car. Why don’t a lot of people do it? Well simply because they don’t have the time to make it and would rather rely on someone else to do it for them.
Whilst Mr. Obama has stated clearly that he wanted to make the United States “the world’s leading exporter of renewable energy”, it is China’s companies that quietly have established their domination in the green energy business, particularly in solar power. The Chinese have already dominated the market by successfully pushing down the price of photovoltaic panels by over fifty percent last year. This situation helps people who previously couldn’t afford to have their own home solar panels in the United States but on the other hand it’s not doing any good to the American clean energy equipment manufacturers. Many people worry that the local manufacturers can’t win the competition. Chinese companies are greatly supported by the government with cheap loans, labor and electricity cost, something impossible to find in the United States.
Will some protectionist legislation help to stop the Chinese solar products invasion? Not likely. The Chinese are furthermore preparing to build plants in the United States to assemble their products, something they learned from the Japanese automakers to combat the protectionist legislation many years ago.
It seems that the United States (and probably Europe as well) will become the consumers only unless they can push down their local products prices to stop the Chinese domination. Mr. Obama has to find a better solution to make his dream come true.
The practical approach and the classic way to do it are to apply the adage, “Use less, save more”. While everyone could agree on that, the devil will always hound the details, so how?
Even before the news of a cooling economy hit the papers, consumers across the globe have been finding ways to save money, trying always to have more with less. This is truer now.
With cooler winters ahead in many parts of the world and rising energy prices, the Alliance to Save Energy predicted that the average American household will have to spend $1,700 more on utility and gas pump this year compared to just two years ago. Using less and saving more is still a good idea, but alone, it may not suffice.
Last year, winter heating cost was projected by the Energy Information Administration to increase an average of 15%. This is not only caused by higher energy costs but by the cooler winters that are expected.
The 15% projected higher heating costs will of course vary and is dependent to some variables like the characteristics of the space heated, the kind of fuel used for heating and where the consumer is located. Just the same, homes using natural gas as its fuel for heating, which comprise 50% of American households can expect an increase in heating cost by as much as 18%; households that are using oil could expect an increase in heating costs by as much as 23%; while those using electricity and propane will have to shell out about 10% to 11% more.
The advancement in technology gives rise to energy saving devices. Before, the main contention was that most of these devices cost more; and sometimes, the amount of energy saved did not really justify the price. But in today’s setup, the effort in cutting the energy cost has made some improvements on the efficiency of energy saving devices. With the threat of a cooling economy, energy saving devices are once again in focus. There are various and very practical devices that could be used in saving energy and they come in different brands, labels, methods of operation and products. Some saving energy suggestions are:
The solar heaters – this energy-saving device provides heating for both space and water. Depending on the type of solar heater that is used (be it a part of the structure of the home or one that engage the use of a mechanical device), solar heaters are definite money saver. It is easy on the environment too. Greenpeace should love this one.
Electrical saving devices. These are devices that you plug into your socket that promise to reduce the volume of energy that you consume by stabilizing the flow of your electric current. The only limitation to these devices is that it could only control a specific volume of wattage, say 3000 watts, at any given time. If the household will use more than the wattage capacity that the device could handle, another device should be plugged in.
Finally, there are the energy saving light bulbs, lamps, heaters, appliances and other gizmos and gadgets.
But the fact remains that saving energy is fast becoming the order of the day taking into account the current realities. So if all the energy saving devices out there will still not suffice, the “use less and save more” principle will still add a good deal to your savings.
