| This research report about selected Smart Grid components presents an in-depth analysis of the development, applications, products, manufacturers, and trends in the development of transmission and distribution (T&D) system automation, off grid energy storage, and microgrids in the United States and around the world. T&D system automation is vital to smart grid development, is badly in need of repair, and has not been designed for the power needs of high technology systems. Battery storage systems can improve power quality and reliability and improve the effectiveness of intermittent renewable energy sources but are not yet cost effective in most instances. Microgrids could serve the specific needs of localized electric loads and become proxies for smart grid development but lack a common set of standards that could drive their growth. The report provides a comprehensive assessment of all three of these areas, cost and regulatory concerns that have limited their growth, the potential opportunities for new applications (particularly for integrating intermittent renewable energy sources into the grid), and an assessment of developing technologies that make the grid “smart”. Projected growth through 2014 for these areas is provided including discussion of energy demand, environmental impacts, economic conditions, consumer acceptance, stakeholder concerns, and government activities as they affect growth rates. The report also profiles manufacturers and marketers of technologies in these areas and the strategies they have adopted to maximize growth and profitability. Scope and Methodology This report includes both primary and secondary research. Secondary research data have been obtained from government sources, trade association publications, business journals, and company literature. Statistical data are included for industry revenue, both globally and for the United States. The market size for (T&D) system automation, energy storage, and microgrid technologies is projected from 2009 to 2014. Potential applications, buying trends, environmental issues, and energy considerations are also reviewed and analyzed. Market size estimates and forecasts are based on government and secondary sources, and the impact of factors such as government grants and incentives, environmental concerns, fuel and energy prices, economic considerations, and demand for renewable energy sources. How You Will Benefit from this Report If your company is involved in renewable energy, electric service, business consulting and integration of electric resources, energy planning, off-grid electric applications, general construction, or simply want to determine the myriad opportunities that exist with development of hydropower you will find this report invaluable, as it provides a comprehensive package of information and insight about conventional and ocean hydro technologies that are not offered in any other single source.

| add to favorites | Solar Energy for the Defense Department | No Picture |
|
| ver the last ten years, the Department of Defense has moved to increased uses for renewable energy in all areas of their functions. They were one of the first government agencies to use passive energy in the form of solar covers for their planes, boats and trucks in order to keep them cooler when needed and warmer when in colder climates. The point was to not only be environmentally efficient but to also be economically wise. Solar energy for the Defense Department is carrying on its plans for sound energy practices at their facilities in Hawaii in an effort to make the transition to solar energy and other renewables. Their goals are to reach a point of totally efficient means of capturing, storing and facilitating the use of solar power. It is hoped that eventually, what the Department of Defense learns from this program can be used by people to run their homes and businesses. Not only has solar energy for the Defense Department been successful, but an energy storage and management project has been implemented in Alaska which uses wind to make up for difficult weather issues that were causing drops regarding fuel use in a distant monitoring station in Alaska. Another example of solar energy for the Defense Department in Hawaii is being managed by the University of Hawaii. A carport that has been built over a parking lot on Maui has solar panels that are combining wind along with electricity from a grid to create, store and use electricity. The energy that is produced is assisting in the saving of power needed to cool the facility. The energy managers are hoping that this project will show the multiple uses of this carport in that it can both save energy as well as create power through photovoltaic panel arrays. Hawaii is a good place to work on alternative energy. Fossil fuel has to be brought to the islands and as a result is extremely expensive and inconvenient. The ability to create fuel locally such as solar, wind, and geothermal can be a big help to both consumers as well as the Department of Defense and other large government and industrial facilities. Solar energy for the Defense Department had a perfect location in Hawaii that they chose to work with 220v ups including wind and geothermal. The Maui Solar plan will create 1.5 megawatt of electricity which will greatly reduce Hawaii's dependence on fossil fuel. It will save a lot of money for the Air Force which will have clean and renewable solar energy to rely on for its electricity. |

| add to favorites | Energy Asset Management Is Beneficial for Enterprises | No Picture |
|
| In terms of energy asset management, companies collect data from energy systems across the entire organization. This data is then evaluated by management so that the efficiency of the systems can be classified and measures taken to improve energy use. As the Climate Registry urges companies to reduce their energy consumption, this procedure can in turn lower carbon emissions and reduce global warming potential. Facilities, companies, municipalities and organizations across North America, its' states, provinces, territories and native sovereign nations, participate in a voluntary agreement. The Climate Registry works towards a common goal to identify, track and record greenhouse gas emissions. This is an ongoing effort to help in the reduction of global warming. A key component under the Climate Registry is emissions reporting. This procedure pushes companies to take action in identifying emissions and to prepare methods that would curtail and manage such. Current and future greenhouse gas emissions can be managed, with the goal of reducing the company's carbon footprint. Within an electrical distribution grid, energy asset management covers all sources -- distributed generation of energy, energy storage devices and 120v UPS. As constant, real-time monitoring of indirect and direct sources is required, asset management software is indicated as these programs can best handle multiple sources and locations around the world. In addition to tracking real-time energy use, greenhouse gas emissions from specific energy related assets can be tracked by efficient energy asset management. Included with this are HVAC systems, refrigeration, lighting, vehicle and transport, among many other types of equipment. Energy reduction efforts can be tracked in this way. Protocols are provided by the Climate Registry to assist in energy asset management programs. These guidelines include an in-depth analysis of asset specific attributes linked to energy use. For a more accurate measure of harmful emission sources and energy sources, automated programs are highly recommended. The software programs can provide a greater oversight, and an hourly record of asset energy consumption. Short and long-term objectives are defined through energy asset management with regards to energy consumption. This reveals opportunity to play from and it will be beneficial to plan ahead of time. The goal is to improve operational performance and reduce energy risk, as energy is a major expense for any company. Are you finding 10KW UPS?Energy risk factors associated with design and operation can be identified as part of a comprehensive plan to manage all energy sources. Elements which create practical opportunities for companies can be combined with any asset management program which can help monitor and save on energy use. Several things are achieved, including energy reduction, cost control and for all environmental health. |

| add to favorites | Living And Working In Sustainable Environments - Energy Storage | No Picture |
|
| There are many types of electrical energy storage; from capacitors, fly-wheel to rechargeable batteries of various technologies. However, in a home, office or factory environment only a few are practical or affordable. On the battery side, as the most practical form of storage, there are some challenges and trade-offs that have to be considered. For example the cost of batteries and their specific performance in terms of charging efficiency, discharging efficiency and self-depletion performance versus price. Charging from Solar or Wind will be most economical for a deep depleted 12 Volt flooded lead acid battery (10.7 volts at no load) to about 87% of charge with an efficiency of ~91%. From 87% to 100% the charging efficiency drops to 55% unless it is charged very slowly which will not be possible for daily cycles. The initial cost for a Raw Watt hour (R-Wh) for flooded lead acid batteries is approximately $0.24.. $0.19. Do you need 12v 200ah battery? The size of the battery capacity also depends on the way you want to use the battery. There will be two numbers of importance, the cost per Usable Watt hour (U-Wh) and the expected life time in cycle days. The U-Wh are significantly lower than the R-Wh advertised by the manufacturer and depend on a number of other factors like the general area of operation between 55% discharge and 13% discharge. When operating in this area the charging efficiency is maximized to about 91% but the cycle life of a lead acid battery is greatly reduced and charts from the battery manufacturer have to be used to determine the realistic cycle life. When used with solar generation or load-balancing, a cycle day is mostly a day of the year. If your energy use is lower at the weekends this can extend lead acid battery life as anti-sulfurization charging can be applied during that period. Charging Efficiency 91% (at U-Wh 32% of R-Wh) Battery Type / Expected Cycle-Life (days) Supermarket Chain Store 12 Volt Car Battery / 300 (less than a year) Marine Deep Cycle / 400 (little more than a year) Flooded Sealed Lead Acid (250 Ah/12 Volt) / 900 (2..3 years) Flooded Managed Lead Acid (1000 Ah/12 Volt) / 1400 (4..5 years) When flooded lead acid batteries are used in the area of operation between 90% charged and 70% charged (10% discharged to 30% discharged) the cycle life is greatly improved but the charging efficiency is not that good unless the batteries are charged very slowly in which case the charging efficiency can be improved to about 83%. In this case the battery capacity is derived from the most efficient charging rate resulting in very large battery banks. Charging Efficiency 55% (U-Wh 20% or R-Wh) Battery Type / Expected Cycle-Life (days) Supermarket Chain Store 12 Volt Car Battery / 350 (less than a year) Marine Deep Cycle / 450 (more than a year..1.5 years) Flooded Sealed Lead Acid (250 Ah/12 Volt) / 1000 (5..6 years) Flooded Managed Lead Acid (1000 Ah/12 Volt) / 1600 (7..10 years) Charging Efficiency 95% (U-Wh 70% of R-Wh) When using LiFePO or also known as Lithium Iron Phosphate batteries, the charging and discharging efficiency is significantly higher at around 95% at a higher percentage of U-Wh versus 100% of R-Wh, but the cost can be 2 to 3 times the cost of flooded lead acid having 2x extended cycle life at 80% of original capacity. Total economics work out to be exactly the same cost over 10 years as the equivalent flooded lead acid battery system for approximately the same storage and discharge performance. However, the storage space and weight for the same capacity is heavily in favour of LiFePO with 1/3-rd of the volume and weight of lead acid batteries, and half the weight and volume of Ni-Fe batteries. Also, when you start looking at nonideal conditions (cold, hot, unpredictable charge and depth of discharge), the lead acid battery performance falls off dramatically and it is worth the current cost of a LiFePO battery system. Charging Efficiency 90% (U-Wh 80% of R-Wh) When space and weight are not so critical a Ni-Fe Battery is a solution, it requires a storage and operating environment of 0°..45° C (32°..117°F) and therefore has to operate in-doors or in a crudely climate controlled area or more sophisticated cooling built into the battery cell. However, charging and discharging efficiency is high with 90% and the cycle time is in the 3000-plus cycles giving it a life time of 10 years plus. Ni-Fe batteries have been known to last 20 years retaining full capacity. What this means for load-balancing systems based on batteries is that the cost for the equipment to charge the batteries efficiently as well as the correct battery size to optimize charging efficiency and life time (time to replacement) have to be carefully taken into account to determine system sizes that can produce a payback from load-balancing. Both systems, flooded lead acid and LiFePO, will benefit from each cell fully managed by an appropriate charger controller rather than using multi-cell batteries that do not allow individual cell management or replacement. Ni-Fe batteries are more forgiving to overcharge and under-charge but require water-refilling on a regular basis or an automatic system to accomplish their automatic maintenance. How often you have to change your batteries or supplement with extra capacity will affect your ROI or cost per stored and released Watt hour (Wh). You may decide it is more cost-effective to add 20% new batteries at the end of the 80% cycle life if your type of battery will continue to lessen its capacity at the same rate per cycle as it did up to the 80% capacity point. In this case you have to plan the space required for the extra 20% beforehand. You can then decommission 20% when the total capacity has reached 80% again and replace with 20% of new batteries and so on. Disclaimer In this article no claim is made as to the accuracy of any values, prices or other information given as they are rough indications or estimations based on publicly available information and the author's experience. Tips for Selecting a Battery Some battery manufacturers are masters in misrepresenting the true performance of their products. Although a Supermarket Chain Store battery normally has a 1 year warranty, it has no Amp hour (Ah) nor a Wh rating and would only survive 150 deep discharge to fully charged cycles depleting its capacity to 50% or failing completely. Do not use batteries for which you can not obtain cycle life diagrams showing after how many deep cycles the 80% mark of capacity is reached. Starting a car or tractor once a day is not a deep cycle, cranking power and cranking cycles have no relevance in a load balancing application. A battery made for the application will have an Ah and or a Wh rating. Be aware that if your application is mission critical design the capacity taking the 80% of capacity at end of life into account. Here are more: 12v 250ah battery |

| add to favorites | What Is the Next Step In Energy Storage and Preventing Inefficiency? | No Picture |

| One of the challenges with solar and wind energy and some other alternative energies is that we don't have access to them all the time. For instance, hydro-electric electricity in some places may not be available in the summer months, rather more readily available with the run-off of spring when the ice melts in the mountains or during the rainy seasons when the water cycle is doing its main business. For solar, it's a similar issue, as "The Sun notoriously doesn't shine at night," and although that sounds hilarious and obvious, I heard that quote from a Nobel Lariat giving a speech on alternative energy at a local university in 2011. Are you looking for 3KW UPS? Wind power is similar in this regard because when the wind is not blowing you cannot collect energy. If the wind blows more steadily at night, but humans need the draw down in energy during the day, then we have a problem don't we? The answer of course is to find a way to store the energy created and then use it at a later date. Some ideas have been to pump pressure underground in giant tanks, which would take the energy being created at the time, and that pressure would blow out during the day turning an energy generation device. That could work. There was an article in Discover Magazine in September of 2012 titled; "Tornado Tech - Excess Heat from Power Plants or Seawater Could be Twisted into a Renewable Energy Source," which brings up a very interesting topic of vortex flows and efficiency of heat engines, propulsion and energy generation. Such a scheme obviously makes sense, but what will the next step be in energy storage? Remember every time we collect energy from one place and convert it into electricity for something else we lose a little bit of energy, we never get 100% efficiency. In the case of wind power and then creating pressure, we lose a little bit of energy in the pumps which pump up the pressure, and we lose a little bit of energy from the friction of the device which turns to generate electricity. Not to mention the energy loss from the friction of the blades turning, and the system itself. We also lose energy in transmission lines. The trick is to prevent inefficiency. And as long as were talking about inefficiency, then we need to be honest with ourselves that when we convert sunlight from solar cells and energy, they aren't very efficient, in the future they may be, but right now they are not. We need to work on efficiency, energy storage, and we need to use the laws of physics without trying to be so politically correct that we fail in these large projects. It does no good to set up a very large energy generation system, give out all sorts of tax credits to help it compete in the free market, when it isn't as efficient as what we already have producing our energy. That just wouldn't be smart business, nor does it stick with the conservation of energy or laws of physics in this domain. Please consider all this and think on it. To know more: 12v 120ah battery |

| add to favorites | 3 Things to Know When Installing a Solar Pool Heater Or Solar Spa Heating System | No Picture |
|
| 3 Things you should know when Looking at Solar Water Heating The advancement in solar thermal heating has resulted in cost effective solar heaters that are almost 94% efficient. This has caused new applications such as solar hot tub heating and much more cost effective hot water heating systems for both pools and homes. Soar Thermal Heating systems compared to Solar Photo Voltiac, are nearly 500% more efficient. As an example the most efficient PV system on the market is only about 16% and cost per Kw is nearly double that of solar thermal. When looking at solar water heating for pools or spas you should consider the following 3 topics before you make your solar investment: Open Loop or Closed Loop solar system Control valve to shut off solar system at night Location Location Location of solar colllectors 1. Open loop or closed Loop solar system is a very important decision especially if you are using salt water or lots of chemicals. Simply, an open loop solar system means the water is circulated directly through the solar system. This means that the chlorine in the water has direct contact with all parts. This type of solar heating system will be the least expensive but will have the shortest life as your may find the chlorine can break down the solar collectors and other parts. PV panel mounting systems are very popular in the international market. Closed Loop systems uses a heat exchanger as a barrier between the solar system fluid and the pool spa water. While this system costs more. The advantages are that you can run the system year round by using glycol or antifreeze. You also will find the life expectancy of the system is greatly increased. 2. Solar Control System- When designing a solar pool system or solar spa, you need to consider water flow. There is no need to circulate the water through the solar system at night. As a matter of fact, this can result in a negative heat loss. A solar control system will have two temperature sensors, one sensor is placed on the output side of the collectors and will measure the heat coming from the system. The other sensor will measure the current temperature of the pool or spa. If the heat output is greater at the spa and the water temperature is less than required (heat demand) then the system will ensure water flows through the collectors. This is done via an automated solar bypass valve system. At nights when the water in the pool is hotter than the solar collector, the control system will ensure the solar collector is bypassed and uses the alternative pool or spa heating system. 3. Location- In order for any solar system to be effective, it needs to be in direct sun light. This means a southern exposure with no shading of trees or buildings. As a rule of thumb the slope angle of the solar system should equal the corresponding latitude where it is installed. A solar swimming pool system should be installed where it receives the maximum exposure for the greatest ROI. see more at: pv mounting system |

| add to favorites | What Are the Advantages of Solar Energy and Its Disadvantages - 50% to 80% Savings Are Yours | No Picture |
|
| The advantages of solar energy are irrefutable, but in any case we should not be afraid to analyze possible disadvantages or flaws, if any. So, when weighing the implementation of solar energy to meet your power needs at home, pause for a moment and ask yourself: What are my expectations regarding solar energy? and What do I want to use a solar power system for? You will spare yourself many disappointments. Technically speaking, solar power systems are improving every day, but their implementation still requires a special commitment on your part, or maybe we could call it a certain enthusiasm for green matters. Some other questions you could ask yourself are: Do I believe that solar power is a feasible response to the fossil fuel energy crisis? Is this really the answer to saving money at home? I think pv mounting systems will develop very well. The advantages of solar energy are many, but it is not the general energy choice yet and requires you to be open minded. We can now examine the specific solar energy advantages and disadvantages in homes and business buildings. Advantages of Solar Energy Solar energy is free and accessible to anyone who chooses to profit from it. The sun sends off its warmth and energy to everyone, to nearly every region in the world. Some places have more sun than others but the sun's energy is not the property of anyone like fossil fuels. Contrary to oil, natural gas and coal, solar energy is a fairly clean and pure combustion. For this reason it does not pollute the environment in any way. Compared to the sun's rays, the exploitation and usage of fossil fuels implies quite a negative influence on the Earth's environment. After you install and use solar power regularly in a whole house energy system you can experience savings of 50% to 80% on your energy bills. Costs of solar energy are not expected to grow in the future, unlike fossil fuel costs that are steadily going up. Disadvantages of Solar Energy The biggest deterrent for most people is the high investment required in advance to install a large solar power system for a whole house, when you have not even begun to enjoy any savings. But if you want to be able to collect solar energy and use it there is no way around investing in solar energy equipment, at least at the moment. This initial investment is why many fossil fuel power plants have not made the switch. It is estimated that the number of years to recoup your initial investment is four to five. Solar energy can be problematic in some areas where large amounts of sunlight are not available. When the climate is mostly cloudy it can be harder to grab systematically the solar energy you need to power your electric system. The first example that comes to mind is Northern Europe, where the sky is often gray. But if you live in this region do not let anyone talk you into believing that you are not able to enjoy the advantages of solar energy. The continuous technical improvements to absorb sun's rays even when we hardly see them are amazing. Anyway, the global picture is quite sunny, if you know what I mean. There are plenty of regions on this Earth blessed by the warm rays of the sun, which are naturally suitable for solar power systems capable of harvesting the sun energy. Some are the Mediterranean basin, Australia, Mexico, and so many African and Asian countries and regions. In the United States, for example, the Southwestern states are great for solar energy because they receive lots of sunlight. Summary of the solar energy advantages and disadvantages To recap, the disadvantages of solar energy are the initial investment and that you live in a rather cloudy climate. Technology takes care of the second, and the first one depends on your personal finances. You can always start small with solar power kits and self-contained solar power systems, which are way cheaper. On the brighter side, the advantages of solar energy are that you can save from 50 to 85 percent in energy bills, it is a clean burning, so to say, and last but not least, the sun and its free energy are not owned by anyone in particular. As we can see, the advantages of solar energy clearly outweigh the disadvantages.

| add to favorites | Honda Portable Inverter Generator, the Best Inverter Generator | No Picture |
|
| It has been about a decade now since those clever fellows at Honda introduced the world's first widely available Honda portable inverter generator. Many would agree that it is still the best micro inverter generator available today. There are three major manufacturers that would argue that their generators are just as good as Honda, and it may well be true. However, Honda is a name that is known for quality worldwide and the name is so familiar that almost everyone who is in the market to buy a generator will consider Honda first. Before the first Honda portable inverter generator was available, the company was perfectly aware of the problems with the old technology and the huge volume of delicate electronics that had pretty much taken over television manufacture, washing machine control, and, of course, the huge numbers of computers in almost everyone's home. The old generators, the sort that ran at a constant speed of around 1500 revolutions a minute produce simple raw AC current which could destroy microprocessors. Inverters had been around for a long time, but these had to be connected to a battery, were extremely expensive to buy and worst of all, many of them produced only a modified sine wave. The true sine wave types had prices that would make your eyes water! Honda was very aware that they could produce a pure sine wave inverter in massive numbers, for a fraction of the price of what was generally available, and from this the Honda portable inverter generator was born. Billions of microprocessors must have sighed in relief. Electrical alternating current that was at least the quality of commercially supplied power. Even before the introduction of the digital inverter generator, Hondo were known to produce some of the quietest suitcase generators available. I know this from my own experience, my very first generator was a used Honda suitcase of indeterminate age that was so quiet that it could be barely heard from just a few feet away. Honda still strives to be a quiet as possible. Normal speech is rated at around 60 decibels, and in normal load condition the Honda suitcase generators are quieter than that, a typical decibel reading would be in the 52 to 57 range. This is all down to brilliant engineering and absolute attention to detail. see more at:where to buy inverters |
