Power Saw Bargains

Water heating is the largest single source of greenhouse gas emissions from the average home (excluding the family car).It accounts for between 25% and 35% of home energy use, making it a huge power guzzler. 
Solar hot water systems are not expensive to install or run, which most people don’t realise.Actually, the real savings start around two years from installation when the solar hot water system starts paying for itself.
A solar hot water system can save up to 90% of an average household’s hot water energy requirements.It can also save up to 3.4 tonnes of CO2 emissions from an average household each year.There are considerations such as location, direction of the roof and the actual system quality which will all affect the performance and efficiency, but the truth is that the sun can provide most of the energy requirements for a household’s hot water.  Any shortfall can be provided from conventional gas or electric supplies.  
Electricity is becoming increasingly expensive and the search for appropriate renewable energy sources is gathering intensity.When one counts the cost that generating electricity has on the environment, the argument for solar power is even more convincing.
There have been significant technological developments in solar hot water systems in recent times.Systems can be ground or roof-mounted, and can be used in any weather from below freezing to harsh desert conditions.
Solar hot water can be installed in existing buildings, not only in new ones.Many people around the world are being encouraged and incentivised by government to replace electricity driven hot water systems.
For example, eligible property owners, landlords and tenants in Australia qualify for generous rebates from Governmenet when they replace electric hot water systems with solar ones.  Under the current system, the Australian Government is providing a Solar Hot Water Rebate of 600 per eligible installation to help people save money on their power bills and reduce their greenhouse gas emissions.   Current calculations estimate the average family will save up to 0 off their energy bill each year if they install a solar system.  
Since government introduced rebates, there has been a huge increase in demand for solar hot water systems, according to Perth solar energy company, Solar MyWorld.People are under growing pressure to reduce their carbon emissions, and the company has seen this translate into increased demand for solar hot water systems.  
A study commissioned by the Australian Government, ‘Energy Use in the Australian Residential Sector 1986-2020 projected a 56% increase in residential sector energy consumption from 1990 – 2020.However, water heating was the only major energy use predicted to decline over the study period, mainly as a result of Government and state energy programmes.   Water heating energy use reached a peak in 2002 at 92.4 petajoules (PJ) and is expected to decline slowly to 8.5PJ by 2020. 
Solar hot water is one of the most simple, yet most rewarding, lifestyle changes we can make. There are now drawbacks.It is not only kind to the environment, but is also cost-effective and low on maintenance.Moreover, a good quality Perth solar power hot water system should last at least 25 years, provided it has been installed by experienced professionals.  Now that’s a hot option!

The next few years are going to be tough for a lot of the people in the modern western world and we are going have to take the lead in the way we use energy more efficiently. At present we are burning up are fossil fuel reserves like there is no tomorrow and we should be planning to a better way of life for us and our children.

Renewable energy is the key to our survival and although a lot of people believe in the new safer nuclear reactors the upshot is they put off a problem of dealing with the waste for future generations.

We need to invest in building more energy efficient homes with solar panels and also with the use of wind turbines. These homes would able us to survive power cuts. With the current reserves of electricity within the UK for example we used to have 20% reserve electricity power generation at present we have almost none and depend heavily on the French to supply us in the event of an emergency.

There is also the problem that recently that the energy companies are dependent on shareholders because of this they are subject to being to take over and therefore would also put the shareholders first over customers. We need to equip our homes with solar power to provide us with heating of our homes with the relative warm climate we enjoy.

Wind power would also be a great advantage if we can supply even a fraction of the percentage energy we use in our homes. This energy even a small amount would allow us to power to run for an example a fridge which if it could sustain the fridge over a blackout would save vital food from going off.

Solar power technology has increased its efficiency in recent times and now we can often see road signs powered by solar power cells. Solar panels are becoming more relatively cheap and finding that all new developments should be looking to use this technology to increase our homes value in terms of being eco - friendly.

Reducing our carbon footprint is essential for making our environment a better place to live it is incredibly selfish for us to just to live for ourselves and not think of our future generations. 
Making local wind farms are going to be a great method of reducing and using one of the earth’s greatest natural renewable energy. It is always possible for us to reduce our energy wastage and improve our lifestyle I always think of how when I visit parts of the world like some parts of Australia that how clean the air is and how lucky they are to have a better climate.

Where I currently reside there is are shipments of scrap metal at the port where I live and that produces metal dust in the air so from this we have a large amount of bad cases of lung problems. If we used energy more efficiently and there was legislation to force us to do something about these problems we would all enjoy a better climate.

Going green should be one of the first things we should learn at school and carry forward the lessons to be learnt from wasting water to burning of our precious fossil fuel to how to learn to invest in the creating the technology for us to survive like solar power, wind farms and hydrogen generation.

For ages solar cookers were made use of in 3rd world countries where electricity and gas was not readily available. Nowadays various solar oven designs are not only used in these regions to make food, but also to boil water for purification.

And like other solar technologies, there’s no reason first world countries should not promote solar cooking at home to help save energy. Although cooking may take four times longer than conventional ovens, no electricity or fuel is used - just the power of the sun.

A number of interesting solar oven designs have been made over the years, but they typically take one of three forms: parabolic design, panel design, or box design.

Parabolic Solar Cooker:

With the parabolic shape, reflective metal alloy is put into a bowl-like shape, where the sunlight is then focused on a single point. The advantage of this type of design is that it efficiently uses the sun’s energy to cook food in the shortest time possible. The only drawback is that it is usually a fixed structure that is hard to transport, and it is the most expensive of the three.

Panel Shape:

This shape usually is in a bowl-like shape, and direct the sun’s energy to one area. But it differs to a parabolic cooker in that it is put together with a number of reflective, flat panels and is less rounded.

The panel shape is not as efficient as the parabolic shape, but it has the advantage of being foldaway, portable, and rather simple to make. These cookers can be found in a number of interesting deigns, but the simplest is by far the one made by folding one of those reflective windscreen blinds.

Box Cooker:

The third type, a box cooker, operates rather differently to the parabolic and panel cookers. Instead of reflecting light to a central point, it absorbs, traps and intensifies the light to create heat.

This results in the entire area of the box to get hot and be able to cook larger portions of food at a time. This design is by far the simplest to put together - all you need is a black cardboard box with one side covered in tin foil and a sheet of clear perspex or glass on top to hold in the heat.

What’s great about most solar oven designs is that they can be built from everyday materials in a few short hours. Like a conventional oven or stove, they can be used to prepare anything - such as roasted meat, steamed vegetables, rice, fried eggs, and baked bread. And since a solar cooker is used outside, it will not heat up the kitchen and place stress on your cooling system.

And since over two-thirds of Americans (according to the Residential Energy Consumption Survey) cook food on a daily basis, just imagine how much power we could save if more of us used solar oven designs during the sunny months.

There really is no excuse for not looking more into solar cooking. With a number of affordable solar cookers and free instructions available on the internet, you owe it to yourself, your kids and the environment to try one out for yourself.

The suns energy or the solar energy is the most abundant form of energy available on earth. The sun is capable of giving us more than heat and light. The sun has been one of the biggest factors dictating every living beings stay on the earth. If we choose the right path, we can benefit more from the solar energy, like generating power for daily use.

What are the advantages of solar energy?

The solar energy solution is gaining popularity amongst the alternate energy solutions.

Green energy solution: When you look at the solar energy solution, you will realize that it uses absolutely no fuel other than the suns light. Moreover, it does not release into the atmosphere anything harmful.

Cheapest renewable power solution: First, the energy comes free. Then, the installation cost is a one-time investmemt. Finally, the investment is recovered within a few years of installation, making the power generated by solar energy absolutely free.

Convenience of storage: You cannot store conventional power but you can store solar power for future use. The suns energy comes to rescue even in the times of darkness! Storing it also ensures a 24×7 supply of power, thus saving you from any power outage.

Low on maintenance: The solar energy systems are easy to maintain. They do not involve high costs or too much effort, thus letting you reap the benefits of the solution comfortably.

How can solar energy be used? Solar energy can be used in our everyday lives by adopting the following solar energy systems:

Solar cooking system: Solar cooking is about cooking without lighting a fire or using electricity! Before you wonder, let me tell you that solar cooking is not about bland food. You can cook in more ways than one ” boil, roast, or bake, cook the way you want! The only demand that solar cooking makes of you is being patient; it is a matter of more than a few minutes. However, it is not asking for too much given that you will get tasteful and healthy food without worrying about paying your gas or electricity bill.

Solar lighting system: You can now light up the entire house, use every electrical appliance without thinking about cutting down bills. The solar lighting system lights up your house even in the nights, thanks to the power storage feature it has.

Solar heating system: You can keep your house cozy and warm using the solar heating system without worrying about costs.

Using recycled cans to help heat your home sounds like a strange idea at first, but a company in Canada has turned the idea into a profitable business. The company, Cansolair Inc., has been building solar-powered heating panels out of recycled aluminum cans and even won awards with their design.

Why Use Pop Cans?

The company’s recycled aluminum can heaters have been described as “green energy and recycling all rolled into one”, and have proven to be very cost effective and efficient as well. One customer reported “on the coldest days of winter I need no other heat source as it easily produces enough heat”.

Cansolair’s solar heater takes up a little less area than a 4 x 8 sheet of plywood and is about 4 1/2 in. thick. It can produce up to 10,000 BTUs per hour and will raise the temperature of the air passing through it by up to 50F. A blower increases it’s efficiency by pushing the air through the columns of cans.

How They Work

The panels are frequently attached to the outside of a wall and provide heat for the nearest room. To be effective, the panel needs to face south (or north if the building is in the southern hemisphere).

The idea is to draw air from near the floor of any room in a home or other building, and pass it through the solar heater, which contains several columns of cans. The air is then returned to the same room near the ceiling and at up to 50F higher temperature. The cans are stacked and have large holes cut in both ends to allow the air to pass inside them while the outside of the cans is getting hot from the sun.

Aluminum is an ideal thermal conductor, which makes the cans ideal for this purpose. While aluminum tubing could be used instead of the cans, the cans are not only cheaper, but actually perform better because their walls are very thin, which increases the heat transfer rate. They are also painted black to improve heat absorption.

Make Your Own

While the Cansolair units are sophisticated, the concept is simple enough that any do-it-yourselfer can construct a solar heater of similar design without too much effort, and using readily available materials.

Daniel Strohl of Vermont built a unit to heat his garage, and Frank Gombik of Ontario, Canada, who constructed one to heat his workshop.

Daniel noted that the south wall of his garage was receiving a lot of sunshine, but the temperature inside was still cold. He constructed a modest free-standing heater, containing 45 aluminum cans. He used a vacuum cleaner hose to pipe to and from the garage.

Frank needed a new double-door entry for his workshop, and since it was facing south, he decided to include solar heaters into the new doors. He used a total of 176 cans in his design, and added some temperature sensing and recording devices to measure the efficiency of his new heaters.

Building this type of solar heater is certainly within the ability of the average handyman. All the materials are either inexpensive or free. Not only are you getting free heating for your effort, but you’re doing your part to help conserve natural resources.

Reducing the carbon footprint is fast becoming the goal of many households across the nation. The use of solar panels can reduce energy consumption by using the clean, renewable resource of the sun to generate electricity. If done properly, this technol

Our solar panel is really a series of photovoltaic (PV) cells (the fundamental unit of the panel) joined together to produce a voltage, whose output is the sum of the individual cells. Building a panel from scratch is a matter of wiring the cells together, affixing them to a flat surface (such as a piece of plywood) and covering the cells with a layer of glass to protect them from the elements. For those of us that don’t want to pay full price but want to save money, there are kits, which contain all of the components. Joining a sufficient number of panels permits the green household to actually sell power back to the Grid.

Although the there are other component required for more complex systems, the basic elements of a homemade solar panel system include four items: Solar panel(s); Charge controller; Battery; and Inverter.

Solar panel: The fundamental and essential component of a solar energy system is the solar panel, which consists of a series of PV cells. These cells are combined to generate an electrical current, which can be used in real time or stored in a battery. The total voltage is the sum of all of the photovoltaic cells connected in the system.

Charge controller or regulator: Maintaining control of the energy flow prevents overcharging the batter and is the job of the Charge Controller. This unit also maximizes the efficiency and life of the system by monitoring the discharge status both in the daytime and evening.

Battery: The electricity not immediately used is stored by a battery or series of batteries. Deep-cycle or marine batteries are preferable to automobile batteries because they are capable of storing all or virtually all of the electricity generated by the solar panels, thus minimizing waste.

Inverter: Solar panels generate and store electricity as DC or Direct Current, whereas our appliances utilize AC or Alternating Current. The job of the inverter is to convert DC to AC to meet our household needs.

Other items need for a more complex system include the Kilowatt-per-Hour Indicator, which is necessary to track how much current is taken from the grid or sold back to it.

As we plan to implement energy conservation tips such as homemade solar panels, we should not forget the less expensive but equally important options such as Energy-saver fluorescent bulbs or things as simple as turning off lights in unoccupied rooms.

In summary, homemade solar panels can be an important part of a plan to implement energy conservation tips. Homemade solar panel systems for the DIY enthusiast and be obtained in kit form in which all of the components are readily available, or they can be obtained new or used from several sources from home improvement stores to eBay.

Like most people, you most probably have been shocked by the continuous increase in the price of electric bills. Now is the time to take action. Here are some steps on how you can minimize your electric bill for the rest of your life.

This articles talks about some simple and easy-to-follow tips that will surely minimize or even eradicate despicably-priced monthly electric bills.

A very basic yet infamous step that most people ignore is to limit the actual use of electric power. You can start with the very room where you are in at this point in time. If you will have to leave it for some time, are you not going to check first if there are any electrical gadgets that are on as you leave? Remember to turn off all electric appliances. Simply switching them off is not enough; it also means removing the socket from the source. It may be simple but this step can help. Each penny is needed to make up a dollar.

Small investments in smart gadgets: The use of compact fluorescent light (CFL) bulbs instead of incandescent bulbs is one smart move. The CFL bulbs cost only a small amount yet they can save you a lot of money and power.

Power Save gadgets: These gadgets enable you to monitor the supply of power in your home. Also, they control the minimum amount of power that your household needs.

Home appliances: A home will continually increase the quantity of electric gadgets it has. Nonetheless, the increase in the price of the electric bill does not rely solely on the number of electric appliances at home but also in the way these appliances are being used. For the regulation of the use of electric power by these appliances, here are some things you can do:

Delay the use of the washing machine until such time when there are lots of clothes to wash

Monitor and regulate your furnace and air-conditioner. A big help for the busy family is the use of programmable thermostats.

Even for just a moment, the TV, computer monitor, and other electrical appliance must be turned off whenever they are not in use.

After being able to save energy by limiting its use, you can also try building your own home solar or wind power system that will generate virtually free electricity for your home. In reality, this trend is proving to be a regular practice among American homeowners. In fact, more and more people across the globe are trying the same system as well. Every time you minimize your electric bill by saving electric power, you are gearing towards saving the earth for the next generation.

The two most popular alternatives in renewable energy for the home are solar and wind power. When the two are used in concert they can provide a constant energy source that is environmentally friendly. You can even mount them onto a system that is connected to a utility grid so that most of the energy to your home is supplied by the system and the grid is used as a backup system.

A solar power system supplies electricity that is generated directly from the sun’s rays. Solar panels which are lined with a semiconductor that generates electricity when the sun’s rays strike it are installed using either a roof, ground or pole mount. These mounts are often equipped with motors that allow the panels to be tilted throughout the day to follow the path of the sun.

The electricity generated through a solar panel is passed to a regulator/controller and then onto an inverter. the inverter converts the direct current to alternate current (AC). This is done because most homes run on AC. Once it is converted it can go into the home and used to power all your appliances and facilities. If it is not converted it can be stored in batteries as direct current.

Electricity follows the same basic path in a wind power system with the exception of the generation portion which takes place in the body of the turbine, which most of us consider the “giant fan” which spins away at the top of the enormous towers they are sometimes mounted on.

Wind causes the blades of the turbine to rotate. The center of the turbine is connected to a generator which creates electricity as it spins around. The electricity is then collected and sent into your structure’s electrical or storage system either to work on its own or supplementing any solar power available.

Wind power requires slightly less initial equipment costs as the bulk of the equipment cost is the turbine which is significantly less expensive than most solar arrays. The downside is that the turbine is going to have to be mounted fairly high off the ground on a tower style mount that is stronger but more expensive to install. An installation of this type will more than likely require zoning approval from the municipality that it is installed in and a great deal more planning.

When you combine a solar power setup with a wind power setup, you can plan for each section to work together to both compensate and complement the other. Wind power can be generated round the clock while solar has its inherent limitations. Depending on how much power you want to create, you can create a hybrid system that uses the sun and wind for a small price. Some guides claim you can do this for around $400 but this will require that you find discounted parts and do all the work yourself. This may be outside the expertise of many people but is doable if you have some DIY skills.

Solar power for homes has truly come a very long way since the early, boxy design of solar panels that most of us have seen. Great advances have been made with respect to solar cell construction which allow a variety of building materials be made with the solar cells incorporated into the design, thus effectively making them almost undetectable.

Solar power for homes can be generated using one of two methods. An off the grid system is not connected to your utility company electricity supply and has to meet all of your home’s needs. It usually has another backup system and will store current in a battery bank for use at night. The other form is on the grid or net metering. It is still connected to the utility company and can either be used as a supplemental system or if you create enough electricity it can be sold back to the utility company.

The basic components to generate solar power for homes are the same whether you opt for a standalone system or a supplemental system. The key component is the photovoltaic panels, commonly known as PV cells or solar panels, these panels are lined with a semi conductor or solar cell that turns the rays of the sun into electricity. This electricity is then routed into a regulator/controller that keeps the current at the voltage/amperage level your system is designed for. The electricity is then routed either into your homes electrical system or into a battery array or storage system that will keep that solar power available when the sun goes down.

If your home is connected to a power company grid you do not have to install a storage system, but it does have its advantages as it will help to further lower your monthly utility bill, and it will make power available to you during a power outage.

Supplementing or replacing your electricity needs with solar power for homes is becoming easier and more affordable than ever. Some building materials include roofing material, awnings, car port roofing and the edges of the panes in your windows. This type of solar panel is called Building Integrated Photovoltaics. When used in roofing material these panels offer the same level of home protection as asphalt shingles while functioning as a solar panel.

One of the largest setbacks to adding or converting your home to solar power has always been the initial cost, there are however a growing number of ways to combat that cost. There are grants available on both the state and federal level to help offset a large portion of using solar power for homes. While the federal rebate may change from year to year, individual state rebates vary from state to state, with some states offering special low interest financing as an added green incentive to rebates.

Aside from reducing your home’s environmental impact, perhaps one of the greenest returns you will see will be in your utility bill which you can reduce or eliminate through the use of solar power for homes. Most utility companies even have a metering program that enables you to sell the excess power generated by your solar power system to the utility company, now how’s that for green! Net metering is a good idea in terms of environmental impact because it gives individuals an incentive to sell their electricity to the power companies which can then be sold to other users. This can reduce the power companies reliance on fossil fuels that are thought to cause many of the environmental problems we currently face.

Solar power for the home has made great strides since its early beginnings. Technological advancements have allowed commercially available building materials to incorporate solar cells, which turns them into solar panels that are virtually invisible to the naked eye.

Solar power for homes can generating using one of two methods. One method is the stand alone solar power system, which will meet all of your home’s needs, including power storage for when the sun is down and not actively generating electric current. The other form is supplemental solar power, where generated electricity is available during the day but the home pulls from the grid at night.

The same basic parts for generating solar power for homes are used for both standalone and supplemental systems. First, there are the photovoltaic panels, also known as PV panels or solar panels. These are lined with a semi-conductor unit or solar cell which will turn the sun’s rays into electricity. This electricity is routed into a voltage regulator/controller that maintains the current at the appropriate level for your system. The electricity then goes into either a battery backup storage system or directly into your home’s electrical system so that solar power will be supplied after sundown.

As long as your house is hooked up to the power company’s grid, you won’t need to set up a separate storage system. However, setting up your own storage is more advantageous as your monthly utility bill be reduced further and you’ll still have power even during an outage.

Supplementing or replacing your electricity needs with solar power for homes is becoming easier and more affordable than ever. Some building materials include roofing material, awnings, car port roofing and the edges of the panes in your windows. This type of solar panel is called Building Integrated Photovoltaics.

While the federal rebate may change from year to year, individual state rebates vary from state to state, with some states offering special low interest financing as an added green incentive to rebates.

Any green project will reduce the environmental impact your home has on our world. However, the greatest pay off will be a reduced or even eliminated utility bill each month. Quite a few utility companies have a metering program under which you can sell excess power generated from your home solar power system to the local utility company, in effect making your meter run backwards. That’s one very green bonus!
