A Bright Future For Solar Energy: An Alternative Energy Source

Aug 31

Posted by Alfred Lancer in Solar Power | No Comments

I was first introduced to solar energy in the movie, Race the Sun with James Belushi and Halley Berry in the lead. It was a story about low- income and under achieving Hawaiian students encouraged by their teacher to join the Solar Car race. In the movie, a car shaped like a cockroach and covered with solar panels used the sun’s rays as an alternative energy source to run the car.

Solar energy is the light and the heat from the sun. Solar energy is free and its supplies are unlimited. There are n air and water pollution caused about by using solar energy. But there is still some impacts on the environment although indirect.

Photovoltaic cells used to convert sunlight into electricity uses silicon and also produce some waste materials. There are also large solar thermal farms and these farms can also be harmful to the environment and desert ecosystems if not properly managed.

Solar energy can be used on different aspects. Solar energy can be used in agriculture. Greenhouses (which is entirely different from greenhouse gas) convert solar light to heat to be maximized in enhancing the growth of plants and crops. Greenhouses has been around since the Roman times and modern greenhouses were built in Europe in 16th century. Greenhouses are still an important part of horticulture nowadays,

Daylight systems are also being used to maximize the energy released by the sun. It is used to provide interior illumination replacing the artificial lighting. Daylight systems include sawtooth roofs, light shelf, skylights, and light tube. Daylight systems when they are properly implemented can reduce lighting-related energy consumption by 25 percent.

Solar energy can also be developed into solar thermal technologies which can be used for water heating, space heating, space cooling and process heat generation. Solar energy can also be used to distil water and make saline or brackish water potable or drinkable.

The solar water disinfection or SODIS involves exposing water-filled plastic polyethylene terephthalate or PET bottles. This process takes a long time, since the exposure time varies on the weather conditions. It requires a minimum of six hours to two days during days with overcast conditions. Currently, there are two million people in developing centuries use SODIS for their daily drinking water needs.

Also sunlight can be converted into electricity using photovoltaics or PV. PV has been mainly used to power small and medium-sized things like a calculator powered by a single solar cell. There are homes powered by photovoltaics. Using solar energy for water and space heating is the most widely use application of solar energy. While ventilation and solar air heating is also growing in popularity.

There are three main ways in using solar energy. The main way of using and converting solar energy is by using the solar cells. Solar cells convert light directly into electricity. Solar cells are also called photovoltaic or photoelectric cells.

Meanwhile, solar furnaces use a huge array of mirrors to concentrate on the Sun’s energy into a small space and produced very high temperatures. Solar furnaces are also called “solar cookers”. A solar cooker can be used in hot countries to cook food.

With all the benefits if using solar energy, there is still a downside for this alternative energy source. It does not work during night time. The cost of setting up solar stations is expensive, but the benefit of using solar energy when accumulated is so much more.

Canada, Green Energy And Economy

Jul 31

Posted by A Noton in Energy | No Comments

The dwindling fossil fuel supply and the possible end of energy systems reliant upon them is of great concern to the world community. And in the midst of the global recession, the economies of individual nations as well as that of the global system are of paramount importance. That these two issues are of moment at this same time invites nations and businesses to to find ways for solutions to one to also provide solutions to the other. As a major global economic player, Canada also plays a role in this crisis of combining green energy and economy.

The combined world investment in natural gas, nuclear and coal powered electricity in 2008 was still smaller than the total investment the world’s nations and multinational corporations and organizations made in renewable energy. In fact, initiatives in green energy solutions attract nearly 148 billion US dollars per year. The largest shares of this money will end up with those nations who invest in and create renewable energy technology and thus nations that commit to green energy will have the advantage in the world economy. Canada is adjacent to one of the world’s economic powerhouses, the United States, and if it decides not to bring in investments in renewable energy, the US will.

The United States Recovery and Reinvestment Act of 2009 invests nearly fourteen times as much in renewable energy than Canada’s Federal Budget of that same year.

Another cause for concern and research and development in renewable energy is the need to reduce carbon emissions in order to halt or slow climate change. The International Energy Agency calculates that the nations of the Major Economies Forum need to spend three to six times more per year than they are currently if they wish to reach their goal of fifty percent reduction in emissions from 2005 levels by 2050.

One notable R&D investment is that of carbon capture and storage. Canada claims to be strongly in favor of this and to be providing robust investment. However, nations who have not evinced a strong commitment to climate change such as the United States and Australia are still outspending Canada’s 19 million by hundreds of millions.

If Canada wishes to enter fully into the renewable energy economy, it already has a strong base from which to develop this capacity. Hydroelectric dams already produce most of Canada’s electricity. Quebec, Manitoba, Labrador, and Yukon produce over 90% of their electricity this way.

It is noted that Ontario, Quebec and the Prairies region of Canada are regions with strong potential for solar power. Canada does not yet use much solar energy to produce electricity, though its government has produced studies showing this could change by 2025, with solar power providing 5 percent of electricity by then. Canada does use solar power more regularly for heating buildings and water as well as drying lumber and crops.

Many areas of Canada are hard to reach and/or sparsely populated. Thus, they do not have easy access to the nation’s energy grid. Here solar power is already put to use through photovoltaic cells. PV cells, when exposed to light, use semiconductor materials to generate directly electric power. In the northern provinces and territory, they have are used as standalone units to distribute electricity, particularly for remote homes, telecommunications equipment and navigational devices. Because they replace the costly diesel fuel systems that used to provide this energy, they also benefit the economy of these areas.

Canada is beginning to increase its reliance on wind power. There are already ninety-nine wind farms generating a little over one percent of Canadian electricity. According to the Canadian Wind Energy Association, the building of new wind farms could allow the country to reach 55,000 MW by 2025. That is twenty percent of Canada’s energy requirements.

Ontario is a demonstrative case of how new energy initiatives in Canada can enhance the economy. They recently passed the Green Energy and Green Economy Act of 2009. One of the provisions of the act is to offer low- or no-interest loans to homeowners in order to pay for the cost of using renewable alternative energy generators and to make their homes more energy efficient.

British Columbia is turning toward a green economy the creation of which has already produced 117,000 full time jobs and makes up over fifteen billion dollars of the province’s GDP. GLOBE Foundation of Canada has estimated British Columbia’s development of a renewable resource economy will make the province worth over twenty-seven billion dollars in ten years.

Canada already has the resources and the systems in place for renewable alternative energy. It remains for the nation to decide how fully it wishes to develop and integrate them into the global green market and economy grid.

Solar Power devices, green energy sources like the field of science is around every day. The children learn with fun optical equipment, telescopes and science lab equipment.

Solar-Powered Lighting

Jun 22

Posted by Owen Jones in Solar Power | No Comments

Mankind desires light. We humans are reliant on light unlike some other species. Our whole world existed only in the day time for millions of years. We woke up with the sunlight and went to bed when the sun went down. Afterward, we learned to produce our own light, but we were not totally successful at it until we commenced using electricity to produce light.

This has worked well for almost a hundred years, but now we realize that the main fuel used to produce our electricity, namely oil, is becoming too difficult to get hold of and more and more wars are being fought to ensure the West’s supply of oil.

Not only that, but greater and greater risks are being taken by oil bosses, which has lead to more and more disasters like that of the deep sea rig off Louisiana in the USA.

Consequently, the time has come, some even say that it is long overdue, that we depend on a different source of power and less on oil. The easiest and least risky way to produce electricity at the moment seems to be solar power. The technology has been with us for decades, but it was not practical for households to use it because it was too expensive, but that is no longer the case.

The capability to use solar power to produce electricity for our lighting and indeed all our requirements is there, already on hand. The only difficulty is that there are many oil baron billionaires who do not see this development as being in their interest. And they are right, in a way, it is not in their selfish interest to decrease our dependence on oil, but it is in the planet’s and its population’s interest. That is mankind’s dilemma at the moment.

Solar panels can be utilized to produce electricity for immediate use either inside or outside the home and the surplus generated can either be stored in batteries or fed back into the electric grid for which you will be remunerated (and remunerated at a very high rate, in some countries).

If you are not ready to come off the grid just quite yet, you could still use solar panels to power some of your external lights. In fact, there is a broad choice of outdoor lighting that provides its own power.

These external lights use mini solar panels, which the manufacturer has built in to the casing of the light to create power from the sunlight during daylight hours and then stores it in internal batteries to be used later.

These lights also have a capacity to run the light on battery power from dusk until dawn. The solar unit determines whether to charge the batteries or give off light by the strength of the ambient light. This solar power set up is ideal for external security lighting and accent lighting in the garden. They are perfect for lighting up the fish pond or the drive too.

Solar powered external lighting has come a long way and it is well worth you finding out more, if you would like to decrease your dependence on electricity produced by oil from the grid.

Owen Jones, the author of this article writes on a number of topics, but is at present involved with outdoor accent lighting. If you would like to know more or check out some great offers, please go to our website at Outdoor Wall Lamps.

Building A Wind Generator

Jun 4

Posted by Arnold Thompson in Energy | No Comments

Most of us think of our energy supply as something which isn’t really in our power to take care of ourselves. The common assumption is that this is something which only the professionals have the knowhow and the equipment to do, so you should just let someone more skilled handle things. When it comes to installing a wind generator, however, there’s no need to get professional help. It’s easy to do it yourself and it can be pretty expensive to have someone else do the work.

Now, if this really was a complicated job, then it would be perfectly understandable to hire someone to do it. However, this really is an easy DIY project and there’s no need to go looking for a contractor to take care of this.

It’s easy to get the information you need online as well as in books and magazines. You can find plenty of comprehensive guides to installing your own wind generator which take you step by step through the process and make the job easy. You’ll also save money by doing it yourself – which is what this is all about, right?

Before you begin, it’s a good idea to look into how you can get tax breaks and other incentives which will defray the cost of your wind generator. Many cities and states have programs in place which reimburse homeowners for part of the cost involved in installing wind generators and other alternative energy technologies.

These programs are meant to encourage the adoption of these alternative energy technologies to preserve the environment. The upfront costs are still up to you to cover; but these programs will allow you to recoup some of your investment in a wind generator.

This is not to say that your wind generator won’t pay for itself anyway – it will and then some. When you generate more electricity than you use, you can sell the rest to your local utility! You’re not going to get rich this way, but this is just another way that your wind generator will pay for itself quickly. You’ll also get the good feeling of knowing that you’re supplying clean and sustainable energy to your neighbors.

The best thing about using wind power is being able to meet your own energy needs using a source which doesn’t produce pollution and doesn’t use limited resources. This helps your home to be self sustaining. In some cases, it may be possible to make your home off-grid, meaning that you do not rely on any outside sources for your energy needs. It’s a great goal to aim for.

Using wind power will save you money on your energy costs, help you to do your part for the environment and of course, you’ll have the personal satisfaction that comes from knowing that you’ve become more self-sufficient. You can do this yourself and stop relying so much on your utility company.

Wanna learn to build make a wind turbine at home? They are a great off grid alternative. Check out how to diy wind turbine in your backyard now.

Use Wind Power For Energy Independence

Jun 3

Posted by Arnold Thomas in Energy | No Comments

Electricity is a wonderful thing without which much of modern life would be inconceivable. However, it can also be a significant expense, one which we usually assume we have no choice but to continue forking over our money to the utility companies for each month.

Of course people didn’t pay their bills without any pressure especially if they do not practice energy conservation techniques. As your household expands, it becomes increasingly difficult to keep the electricity consumption to its minimal. Sometimes when you shop for new electronic items, you often think about the electricity it consumes and then finally conclude that the purchase is not worth it.

There are also very good environmental grounds for wanting to reduce your energy usage. Most of the electricity which comes into our homes is made by burning fossil fuels; these are no-renewable energy sources and it is not at all unimaginable that some of you reading this right now may see a day when these fuels have been depleted. If you’re interested in protecting these finite resources, the best thing to do is not to use less energy, but use energy which comes from a different source.

Fortunately, there is ongoing research with the various energy alternatives with all of them used today. Solar power plants currently exist to provide clean energy to facilities while wind generators power small cities that are on higher grounds. Other energy alternatives are also being looked into, solar and wind power remain as the most accessible resources.

Your household could begin using these alternative energy sources to lower your dependence (and your bills) on the local utility companies, instead using environmentally friendly energy. For some homes, it may be possible to become completely energy independent and make electricity bills a thing of the past.

However, solar power is not feasible for most of us, at least not if your plan is to meet all of your energy needs. Solar panels are very expensive and you will need a lot of them to provide all of the energy your home needs.

Wind turbines are different because they can easily be made by acquiring materials that can be found online or in the local junkyard. There are also a lot of resources on the internet that show the benefits and ways to become energy independent with wind turbines. Once you have all the materials and knowhow in building a wind turbine, you can build lots of them to power your entire household. If you live in an rural area, you get even greater advantages from wind turbines.

Since wind turbines are so easy to build and the cost within anyone’s reach, wind power is certain to be a growing part of the energy plan for the average home. Wind power offers a limitless source of clean energy and it can save you enough money to pay for itself many times over in a very short time.

Looking for something that can teach you how to build your own residential wind turbine easily and quickly? This is a good site to learn. You’ll learn to make a home wind generator at home easily.

Teach Yourself To Make Solar Panels

Jun 1

Posted by Owen Jones in Energy | No Comments

Many people are fed up of the escalating cost of electricity, but they do not know what they can do about it. They have turned lights off; they have not switched lights on; they have unplugged items on stand-by and they have turned the central heating down and the air con up and it has only saved them pennies. Yet still the electricity bills go up on a regular basis. It is very frustrating.

We have all heard of alternative and sustainable sources of energy, but the question is: how can average people implement these technologies into their own homes? One phone call to a professional solar power installation company will convince anyone that solar power is only for the well-off.

Likewise with wind power generation. A single device, which may or may not satisfy the electrical needs of one standard household will cost in the region of $45,000 and it is thought that, if it meets expectations, that it will pay for itself in ten years time. $45,000 is too much money for most people, but having to wait ten years to realize that investment is too long for most individuals too.

So, at first glimpse, it looks like the average person is at the mercy of the oil companies and the electricity generators. However, it does not have to be like that. There are other means of tackling the problem and extricating yourself from the control of energy providers. The first method would be to buy the solar power units and install them yourself. That would save you a great deal, perhaps up to 50%. But you could go a step further and make the solar panels yourself too, which would save you a lot more money.

The fact is that the more of your own labour that you can put into the scheme, the more you will save, because the labour constituent in any task usually amounts to about 50% of the costs. We all know how costly it is to call a plumber in to fix a leaking pipe or a roofer to replace a slate. $100 for a slate? $100 for a dribble of solder? No, it is the tradesman’s time and the same is true of solar panel fitters.

The way out is to learn how to make the solar power units and install them yourself. It is not difficult. Any teenager can learn how to do it and so can you. Take it from me, learning how to assemble and install solar panels is not difficult. Just try it and see for yourself. You will amaze yourself and your friends. You may even turn it into a business!

The thing to do is get a reliable kit or a plan from a trusted source. This could be a neighborhood hardware or hobbyist store or from a specialist website on the Internet. Once you have your design, you can buy the pieces of equipment. They are commonplace and on hand in most DIY shops. Then it will take you about a day to make a solar panel that will provide about 100 watts.

This may not seem like much, but it will power many types of small machines or two average light bulbs. The trick is to keep adding to your stock of solar panels until you are entirely free of the electricity grid or even selling electricity back into it.

Can You Convert Your Home Into A Solar Home?

May 23

Posted by Owen Jones in Energy | No Comments

When it comes to converting your home into a solar home, there are a few options, because not all homes have the same problems, the same requirements or the same potential sustainable power sources. Therefore, if you are going to try a total conversion or even get off the grid entirely, you will either have to do some do research or call in an expert to make a survey for you.

If you call in an expert, try to get an independent one, so that you can work out the costs of satisfying your energy requirements yourself. You will have to pay for such a survey, naturally, but you could carry out a report yourself with a bit of work on your part. In order to create a solar home, you may find the rest of this piece interesting.

There are fundamentally two types of solar design: passive and active solar energy. Passive solar energy can be used to supply heating, cooling and natural light for your home. Active solar energy is used for powering home appliances, tools and lighting. It is the perfect combination of these two kinds of solar energy that you will try to achieve, if you are trying to convert your home into a solar home.

You can make use of passive solar energy methods in many ways, although they are more easily built in during the actual construction phase of a new home. The largest area of glass should face south or be within 30 degrees of due south. This will catch the maximum amount of heat. This heat can then be distributed around the house by stone floors and stone walls.

The central heating ducting and furnace fan can be used to assist, if necessary. If the house becomes too hot in the summer, awnings or even solar panels could be dropped down in order to put the windows in shade. When thinking of passive solar energy, you should endeavor to think of means of supplying warmth and coolness without using electricity. For instance, a skylight at the top of the stairs will permit the warmest air in the house to escape, since hot air rises. This will cause cooler air to be sucked into the house at lower levels.

The other aspect of a solar house is the generation of electricity by the use of solar panels grouped into solar arrays. Solar panels make use of photovoltaic cells to convert light into energy. This energy can then be used to power ordinary electrical appliances of all sorts or some or all of it can be stored in batteries for later use. Conversion from AC (alternating current) to DC (direct current) and back again, if necessary, is a simple matter.

Solar energy can also be used to warm up water for the pool or for the home. The most common sort of system uses pipes filled with a type of anti-freeze to collect the sun’s heat and pass it on to tanks of water by means of a heat exchanger.

A solar home uses energy efficiency to minimize the necessity for heating, cooling and electricity. The use of higher grade lagging, more energy efficient windows, kitchen appliances and lighting than those utilized in traditional homes, will save you a lot of money and energy. As you can see, some of these changes, particularly the passive ones are structural, so hard to apply in many homes, but there is always something you can do to reduce your energy bills and gradually convert your home into a solar home.

Why Go For Renewable Wind Power?

Apr 15

Posted by Owen Jones in Energy | No Comments

Electricity created from wind powered turbines is one of the most prevalent forms of energy from alternative sources and it is the fastest-growing variety too. Wind turbines are turned by the natural strength of the wind, so make electricity without ‘burning up’ any fossil fuels in the procedure. The faster (harder) the wind gusts, the more electricity is produced.

Therefore, wind turbines are best located where there are sustained periods of high wind. The coast line is usually a good location to place wind turbines. In fact many coastal towns and cities are supplementing their existing conventional electricity supply with electricity produced from wind turbines.

You can still produce electricity from wind, even if the wind does not blow very hard where you live, but the return will be less. It could still be adequate, but perhaps you should check out solar panels too. For instance, it may suit your location to have a wind turbine for the winter and a couple of solar panels for the summer and winter back up.

Manufacturing a wind turbine is not rocket science, most people who are skilled with their hands can assemble a wind turbine with the aid of a good set of DIY plans. The real trick is to get all the parts that the plans say you will need before you start. That way, you can concentrate on following the plans without having to nip off every now and again to find a part.

One valid point is that you should not be worried about producing too much electricity, because many the energy companies in many countries are required to buy your surplus electricity back from you nowadays. This is not a difficult process, you just have to remain plugged into the grid and your surplus electricity will flow back into the grid changing the numbers on the meter automatically.

In this case your meter is read monthly or quarterly as usual, but you will be given a refund rather that a bill. The more wind turbines and solar panels you install, the bigger a repayment you are likely to receive. In some cases, the units of electricity that you sell back are worth up to twice the units you use from the same electricity company.

Apart from the fact that you will not be getting an electricity bill every month or that your bill will be vastly reduced, a very significant point is that you will be one of the very, very few people who is not badly affecting our planet. You will not be so responsible for the greenhouse gases that are created by making conventional electricity.

You have nothing to lose by learning more about generating your own electricity, coming off the grid and doing your bit for the natural world. The very least that can happen is that you read the information and become wiser on the subject and you may not implement you knowledge that you have learned. This would be a real pity, but not a big financial loss.

Why Not Assemble Your Own Wind Turbine For Free Electricity?

Apr 5

Posted by Owen Jones in Energy | No Comments

Have you ever thought about building your own wind turbine? It is not as simple as building your own solar panels but it is not hard either. Making your wind turbine look attractive is a bigger problem than making electricity from it. The first thing you have to do is invest in a set of plans to make a wind turbine and then set about buying all the components.

Assembling the parts is straightforward. The bits and pieces can be picked up cheap from vehicle scrap yards and your local DIY store. Just imagine being even only 50% self-sufficient in electricity? Add in a few solar panels or a second wind turbine and you could soon be off the grid completely.

Everyone knows about the continually increasing cost of electricity and that it would be a good idea to generate energy from the wind and the sun just for the cost of the generators – the wind turbines and the solar panels – so you may be asking yourself why it is not a good idea to just go out and buy what you need from a professional installer.

Well, the answer to that is cost. Professionally installed wind turbines can cost tens of thousands of dollars and it can take 20 years to recover the cost. On the other hand you can make your own for between $200 and $500.

If the turbine saves you $200 a month then it is evident that you will have recouped your costs within three months maximum, if you assemble the turbine yourself. This is a very good incentive as with a little regular maintenance it will last you 15-25 years. Let’s just say 15 years or 180 months at at least $200 per month. That is $36,000 or an 7,200% return on investment.

Wind generated electrical power is very green as it takes practically no fossil fuels to produce it. I say practically none, because it may need a little engine oil to keep the blades turning smoothly. And that is it. You may have to replace a bearing from time to time, but that is the scope of your maintenance program. It is not severe. You will also have to put some water in the batteries from time to time as well, unless you buy the sealed units, which you cannot fill up.

It really is not so hard to build a wind generator. The average DIYer can complete this project with simple tools. There are detailed instructions and drawings available on the Internet or at DIY stores to manufacture a wind generator in your workshop at home.

So why not start to make yourself a wind turbine today? Fix it on a roof or a pole and start generating your very own free electricity. You could be off that grid more quickly than you know it and you will be doing more than your bit to help the planet too.

If you want to read more about home-made wind turbines and solar panels, there is plenty of advice on the Internet.

Building Your Own Solar Panels

Apr 2

Posted by Owen Jones in Energy | No Comments

Everyone these days is conscious of the issues of climate change, or as the boffins used to call it, global warming. It appears that even those people who call themselves experts do not know what is taking place. It is not very heartening. However, what everyone does know, even without self-styled expert advice, is that the rate that we are using fossil fuel up is unsustainable, that that means that prices will go up and that it looks like the West is on the slippery slope.

So, what can we do about that? People are looking for leadership and assistance to lessen their dependency on traditional sources of energy like the national power grid and the petrol station, but the people that own these products are loathe to give any real advice in case they lose their hold on society. People are beginning to want to make themselves less reliant on the traditional power suppliers and would like to go it alone. Unfortunately, most people do not know where to go for advice, but they have some imprecise idea about putting up their own solar panels.

However, without any easily comprehensible government subsidy or advice, people are left to do their best alone. And the fact is that the specialist installation of your own solar panels is expensive. It costs thousands of Dollars, Euros or Pounds, wherever you are, which is why some people are looking into a do-it-yourself (DIY) solar energy system.

Sadly, without any appropriate guidance, home-made solar panels will scarcely power a low energy light bulb in the midday sun. A better way is to purchase a self-assembly kit from a reputable company and put it together yourself, following their instructions. After all, we all know that the labour element of any job is often equal to or more than the cost of the components being fitted. These kits come with everything you have to have to install your own solar panels.

These self assembly solar power packages are well put together and the instructions are normally well written and easy to follow. However, it is worth buying from one of the better known, big companies like GE, but you can do this from a web site that specializes in home sustainable energy systems.

You might like to turn the assembly of a few of your own solar power units into a family project, because that will teach the younger members of the family about how worthwhile energy conservation is and introduce them to electronics.

These home solar panel systems are wholly expandable, so you do not have to deprive yourself of that new dishwasher, although the fact is that modern appliances are using less power than their older equivalents did.

Just imagine if you had a bank of your own solar panels and you became 50% independent of the national grid. And then you put in a few more panels when you had the time and eventually became totally independent of the grid! And then you began adding a few more and were actually selling electricity back into the grid. It is all possible when you have your own solar panels.
