Alternative Energy Sources for a More Efficient Home

Are you looking for a way to power your home with a natural source of energy? Nowadays, more than one alternative to fossil energy have been found and put to use.

Depending on the choice you make, certain appliances might be better than others. For instance,if you decided to purchase a hot water tank. While there could be several options to choose from. If you were to utilize solar energy for your house, a water tank using this form of energy could be best. However, it could be remarked that appliances using alternative sources of energy could be more expensive.

More than one form of alternative energy could be learned about. Among these sources of energy a person could find solar energy. Similarly to wind energy, after the purchase of the equipment needed, there should not be a cost associated to the air or the sun rays utilized to produce the electricity. Concerning solar energy, at night when there is no sun rays, for instance, the stored energy from a sunnier period could be used.

In fact, after a person amortizes the cost of the material used to be able to employ sun rays as electricity, we can note that the solar rays themselves are not paid for.

While corn for instance could have been cited among alternative sources of energy, the possible consequences of the use of this food crop for energy generation could be important. In fact, if using corn to produce ethanol is cheaper or leads to more benefits than growing corn for food, prices could go up. As a result, food crops do not appear to be the best sources of alternative energy.

Water, as well as, wind power are also greener sources of electricity compared to oil. These two sources of energy are free within themselves, because rain and wind are not paid for normally.

A person does not have to use solely one alternative source of energy. A house could be powered by more than one source of electricity. Actually, being able to use multiple sources of energy could be a safer approach to being energy independent. Nonetheless, starting with one might be easier than going for several sources of energy at the beginning.

A person who wants to make his/her home greener in terms of energy could find on the internet a lot of information. In fact, books as well as videos have been made on the subject.

  • Fun post, I surprisingly enjoyed glossing over it, keep up the good writing.

    • Auth:

      energy from solar panels can be stroed in batteries for when there is little sun light. its very expensive to install, maybe 8 grand upwards for home systems, hence its usually just used for heating up water etc.. but average *home* system can take on maybe up to 40% of that household’s annual electricity useage.. it is rather expensive per square metre to buy as silicon is not so readily available to make it cheap.. but once its up there it doesnt need much maintenance except to clean it, etc.wind turbines are expensive to install but once up, not much maintanence is needed, checked up maybe every few years.. the energy can be stroed in batteries when there is no wind present.so, i guess its def not answer B and C.edit: wind and sunlight is free so it isnt expensive to *use*

      • I am a international stednut, and this is the second draft for my final essay in English class.It’s a compare/contrast essay, please fix my grammar errors, word choice, verb tense and enhance the conclusion paragraph. Thank you! Green Roofs or Solar Roofs ? You want to contribute to our earth but have no idea? Everyone knows Global warming and unban heat island effect are making inroads into the places where you and your family live. We all know that is a serious issue, and also have positive attitude toward it.Suppose that you are not a boss of an enterprise, therefore, you are powerless to decide how to emission air pollution or recycle resources. Don’t be discouraged! You still have a way that is to develop the idea of green design to protect our earth. Green design is an internationaltheme that has been discussing for many years, and was promoted in “Leaders Summit Meeting” in Brazil in 1992. It is called Ecological Building in Japan and Sustainable Building in Europe. How to put the idea in use? Home Green Design is an affordable way for everyone. I am going to introduce two ways to save energy. They are green roof and a roof covered by solar panels. This essay will show their advantages and disadvantages of the following: 1. Expense; 2. Workingrequirement; 3.Function. Despite the fact that everyone knows the benefit of solar panels, I will argue that green roof is worth than solar panels. First, you do really care about the expense that green roof and solar panels might cost. For a100 sq foot, you need about $25,000 to install solar panels on your rooftop. The system works at least 25 years. On the other hand, it will cost you $1,000 per year. Is that worth? Itdepends on your personal utility rate of electricity. You would save a small amount of money if you are living with a big family. But a fact that you have to consider is one dollar tomorrow probably won’t have same value as today. Otherwise, you still need to pay the upkeep of the system every year and the charge of basic power for keeping it working. It is priced $1,500 for the same area as 100 sq foot, and the maintenance will not be the problem. Basically then, all you need is a waterproof rooftop, a layer of soil and a bag of seeds. The idea of Green Roof is much cheaper obviously and has lower maintenance than solar panels by comparison. Next is the working conditions that for each one. Before you choose one of them, you might need to consider that the area you live is sunnier or cloudier. Solar panels that as the name hints, is a system that has to be solarized under sunshine. In addition to sunshine, theGreen Roof also needs adequate raining to support them growing. If we simply consider that the best environments for them, solar panels need less conditions than green roof. Actually, solar panels will still work on a cloudy day. Of course, no one expects that the system can maintain same efficiency as it used to be on a sunny day. However, that is probably enough for keeping a lamp plus a computer working for one day. Unfortunately, solar panels do not fit in a winded area, because the panels might be damaged by blown stuff. In this stage, they are almost in a tie. Taking that green roof is working 24 hours a day into account, I guess that green roof is a little bit better than solar panels. Lastly I will compare the most important part which is the function of them. In theory, solar panels can basically reduce your energy consumption. What would be powered with solar electricity are the things such as the refrigerator, the computers, the TVs and the airconditioning, etc. Sounds great! But something you do not know is solar panels efficiency averages only 20% to 40%. Solar panels catch sunlight and convert to another type of power that we usually use for home electronic appliances. The system loses much energy during theconversion process. You can’t make appliances working unless you get enough energy from sunlight. So how about green roof and its benefits? It not only filters rains and air pollutants, but also keeps the house warmer in winter and emissions heat in summer. Sometimes it caneven provide a habitat for birds and some small animals. To choose solar panels or green roof is a fascinating question. It is a tough choice for either, I will personally choose green roof anyway. Solar panels are still an immature technology somehow, especially in converting energies. In addition, price is also a point to be considered. I believe that to protect living environments is important for individuals, but it is unacceptable ifno one can solve the problems that I mentioned before.

  • Valuable info. Lucky me I found your site by accident, I bookmarked it.

    • I have been doing some research on solar panel and wind turnbie systems. The pricing is crazy. For a 10Kw solar grid tie kit system is between $35,000 and $40,000. If you install batteries add $3,000-$5,000. 10Kw will only power a small to medium home without electric heat. Using my electric usage and info from my local electric company payback is 60 years for solar and 361 years for wind. This is unexceptionable. The manufactures of the solar and wind are gouging the consumers. They are using the excuse of supply and demand for the high cost. When demand goes up so will mass production and the price will go down. This is true, but they are making a huge profit on what they are making now. Some items are in the 3000% markup range. Are the power companies keeping the price up so their profits don’t suffer? My local electric supplier has an ENERGY PARK that you can go see solar and wind power in action and check out real time data online. They have a 4Kw solar array installed and claim it cost $30,378 installed and a 2.5Kw wind turnbie that cost about $20,000 installed. I think they are giving false numbers to consumers so you won’t go green. I was able to find a 3.5Kw kit online for $9,000. This doesn’t include any type of mounting materials. You can add $800-$1,200 for these materials. An installer will will charge you $2,000-$4,000 to install it. For the sake of argument lets say this will cost you $15,000 to install but still way out of line for you and me to install. That is a far cry from the $30,000 the power company claims. The power companies don’t want you to make your own electric. They are keeping the cost high so they will still make money off you. A 210w panel sells for around $600. They probably manufacture it for under $50. The cost needs to be $100-$150 to the consumer to make it affordable to the average home owner. 50 210w panels make a 10Kw system. That would be $5,000 not $40,000. The manufactures are raping us and the power companies are helping them to keep prices high. When will we get the technology at a proper cost? Let me know what you think.In response to the first 5 answers, Yes, if demand increases so will mass production and thus supply will increase and this will drive the price down. I looked into panels from China. From what I was able to find panels sell for $0.17-$0.45 per watt. In the U.S. they sell for $3.00-$5.00 per watt. Manufactures in the U.S. have lobbied for a higher tariff on solar products that makes them impractical to import on mass. These companies want to keep the price high so their profits stay high, and the power companies do not want you to produce all your own power. That would put them out of business.In response to Steve R, You need to do more research before you post another retarded comment like that. Air DOES have mass (just not very dense). When air is in motion it is called WIND . This motion creates energy. Have you ever heard of a tornado ? Get your facts together next time.

  • Greetings from Carolina! I’m bored to tears at work so I decided to check out your blog on my iphone during lunch break. I love the information you present here and can’t wait to take a look when I get home. I’m surprised at how quick your blog loaded on my phone .. I’m not even using WIFI, just 3G .. Anyhow, superb blog!

    • First of all, the conversion is chacemil to electricity, as in the chemistry of a car battery which provides an output voltage.To meet your needs, you need to figure how much useful sunlight you will have per day. Such sources as the Weather Channel, or National Climatology office can supply that to you. You need to determine the total load. Just add everything up, and that is the load you need to have sufficient energy to provide power for. If this works out to be, let’s say 200 watts, then you need at least a 200 watt solar panel, provided that you have enough sunlight from the time that you get up in the morning, until you go to bed at night. Count on it, you won’t have enough sunlight for your needs, unless you live up in Alaska. Even then, there is part of the year where there will not be enough light at any time of the day. What you need, for full 24 hour coverage is a battery bank, and unless everything will run on 12 or 24 volts, then you need 1 or more inverters. With inverters, you lose 10% in conversion loss from DC to AC. Batteries should be RV, Trolling motor, or best yet, electric fork lift batteries, or the reasonable equivalent of such as these. I would recomment at least double to quadruple the total energy need for the solar panels, and to multiply the battery capacity by the total load supply that you have figured out, for at least a 24 hour run time. All of that, then multiplied by 90% to know how long the system will provide power, IF you use any DC to AC inverters. Within reason, the larger the battery bank, the better. Do NOT use regular car batteries, they will not last as long as you need them to last, unless you understand the difference between cranking amps, and reserve amps. Another point is that auto batteries are simply not designed for this kind of service.
