By way of nuclear waste, carbon emissions, and other pollutants, energy production can damage the environment severely. These sources are being used up rather quickly as well as causing severe environmental harm. One source that is available in vast quantities and is replenished continuously is the sun. This brings us to alternative solar energy. Solar energy will be consumed, unlike most non-renewable energy, in the same place as it is produced—meaning more US jobs stay put in our country.

One reason that home solar power is an excellent option for energy is that you will pay less for utilities each month, and you may be able to eventually to stop using a utility company all together. Your home will also increase in value.

Heating water and generating electricity are just the beginning of what can be done when using solar energy as an alternative. It can be used to heat your swimming pool, to cook, to light landscaping, as passive solar design, and to pump water.  Solar energy offers options ranging from a full scale photovoltaic generator down to a smaller project such as a solar cooker or lights.

By designing you garden and home well so that your cooling and heating bills are greatly reduced, this allows you to use passive solar design. You can save money by not having to buy or maintain equipment by making use of this technology. Passive design is more likely to be a more efficient use of solar energy rather than adding solar technologies, which may not be as completely, energy efficient as you would want even with your greatest endeavors.

Photovoltaic cells (PVs) are the technology behind alternative solar energy, which are typically semi-conductors with two silicon layers. It is imperative that the individual hired as your contractor possess a full understanding of how PV cells work.

If you’re a do-it-yourself person, than there are several online projects that you can do without taking up too much time, and these will satisfy your need to do a fun activity. You may want to consider using both wind and solar power together since using alternative energy is an excellent idea.

A substantial investment, using alternative solar energy can be a very expensive task sometimes. There is no reason that you shouldn’t extort all of the subsidies and tax credits made available to you. The Database of State Incentives for Renewable Energy provides a wealth of information. You can go to www.dsire.org to access the database to explore what incentives and subsidies are available in the area where you live.

Consultants on Alternate energy The choice energy consultants let us know that the change from the petroleum-driven economy and society will not be a smooth one, on the whole. The quantity of new technologies and frameworks that need to be developed and built is staggeringeven as Germany achieves powering ten percent of the entire country through the utilisation of air turbines and solar arrays, even as concern after establishment is springing up, assisted by numerous governments ‘ tax breaks and refund motivations, to drive forward the choice energy mission. We have lain torpid on alternate energy on the grand scale for so very long that we presently have to scramble to play catch-up as access to cheap oil skulks ever closer to being a thing of the past. Experts on alternative power also let us know that we need multilateral, world efforts in concert with one another in the direction of getting away from the heavyalmost totaldependence on fossil fuels. They are positioned to become too pricey, burning them is polluting the atmosphere, and digging for them is interrupting the natural environment. We have about thirty years left of fairly inexpensive oil and gasand advisors say that inside twenty years beyond that point, we had better be at least ninety percent independent of them. Unfortunately, at the time the world is typically not acting as if this is the case. The thirst for oil is growing, not slaking, and it is growing quicker now than it probably did even in the 1970s. One of the major issues of transition, the consultants mention, is that higher oil and gas costs stimulate the economy ( This flies in the face of what many energy supposed gurus and many members of the general public believe, but the truth is that oil and gas are found and manufactured and transported by enormous companies who employ multitudes of staff employees and contractors ; and from their massive profits their stocks remain lucrative on The Street. ). Alternative, solar panels or green energy has to become more market-place friendly, more moneymaking to stockholders and wannabe employers. Wall Street doesn’t like change ; so there is resistance to this much needed commercial transition. It is actually because of this that many consultants are saying that we need a global, governments-backed initiative put into place ; we are told that we won’t expect the new economy to spring forth overnite, all clean and polished and perfected, from the black ashes of the fossil fuel economy phoenix. It is most vital that the rich, big-production nations eg the US, Japan, Western Europe, and others be the ones to spearhead the effort to get off the traditional fuel dependence. Smaller, poorer states are very simply never going to gain the level of power production thru coal and oil that these states havefor by the time they would be prepared to, the cheap access to the normal fuels will be gone, and they’ll never be well placed to sustain their newly-risen civilizations at that point as we’ve been ready to do. The time for transition from black to green is now. For more information check out www.solarpanelcostnow.com.

At the Fourth Safety Week event held at the Diplomat Radisson Blu Hotel Residence and Spa, it was revealed that environmental friendly water and electricity plants are to be introduced in Bahrain

At the Climate Change and Global Warming Summit held in Bahrain, the Electricity and Water Authority Minister, Fahmi Al Jowder explained, “We already aide by strict international criteria in our projects, with highly acclaimed international experts being brought in to study their potential impact.”

Jowder further noted that the authority was already undergoing multiple checks in order to ensure that they do not cause any environmental threat. Measures are being taken to ensure that the standards of the power plant comply with the international standards.

“More than BD 18 million has been spent on the second phase of rehabilitating Riffa power plant to drop emissions from 540 to 74 milligrams per cubic metre to bring in line with international standards,” Jowder said. The Hidd and Sitra plan were also being worked on to ensure that within the next two years the third phase of rehabilitation would be complete.

Jowder also revealed that Bahrain and other GCC countries were to take place In the Cancun Climate Change Conference that is being held in Mexico next month.

Oil and Gas Affairs Minister, Dr. Abdul Hussein Mirza stated that Bahrain is soon to be home to hybrid wind and solar energy plants at a cost of BD 3 million. A Japanese company has conducted tests on the wind energy available in the county and an American company is to conduct tests on the solar power.

Bapco’s Chief Executive Faisal Al Mahroos commented stating that they had plans for Bahrain’s first fuel station selling low sulpher diesel to private vehicles.

The event concluded that Bahrain is as of now undergoing a process of a green revolution obliging them to follow international green standards.

The Ways that the Military is Using Alternative Energy

article
Published: July 23, 2011Posted in: GeneralTags: , , , , , , , , , , , , ,

The US army is aware of that its branches must revamp their pondering concerning how to interact in “the theater of war” in the new, post-Cold War planet of the 21st century. One matter that the military leaders stress is the wish for the forces deployed in the show to be capable to be a lot more energy-independent. At this time the US army has policies and procedures in place to interact with allies or sympathetic neighborhood populaces to improve its forces in the area get their required vitality and clean h2o once engaged in a foreign army campaign. Nevertheless, this is not wholly reliable, as the US may properly uncover by itself dealing with unilateral military activities, or possess alone in a circumstance wherever its allies cannot improve it with the resources it must conduct its military measures successfully.

The US military is quite involved in specific choice energies that, with the right explore and improvement technologically, can generate energy independent, or at the very least a excellent deal much more so, on the battlefield. One of the points that greatly interests the army together these strains is the advancement of modest nuclear reactors, which could be portable, for making theater-local electricity. The army is impressed with how clean-burning nuclear reactors are and how energy efficient they are. Making them portable for the normal warfare of currently’s extremely mobile, small-scaled military operations is anything they are researching. The a lot outstanding point that the US army considers these little nuclear reactors would be valuable for requires the elimination of hydrogen (for gas mobile) from seawater. It additionally considers that converting seawater to hydrogen gas in this way would have less adverse effect on the natural environment than its present practices of remaining provided out in the subject.

Seawater is, in simple fact, the army’s best curiosity once it will come to the subject of alternative energy supply. Seawater can be endlessly “mined” for hydrogen, which in turn powers superior fuel tissues. Using OTEC, seawater can additionally be endlessly converted into desalinated, potable drinking water.  Potable water and hydrogen for power are two of the things that a near-future deployed navy power should need most of all.

In the cores of nuclear reactors—which as acknowledged above are gadgets hugely interesting, in transportable form, to the US navy—we encounter temperatures increased than 1000 degrees Celsius. Once this level of temperatures is combined with a thermo-chemical water-splitting procedure, we have on our hands the a lot effective implies of busting straight down water into its element parts, which are molecular hydrogen and oxygen. The minerals and salts that are included in seawater would have to be extracted via a desalination approach to make the way clear for the water-splitting process. These could then be utilized, like in vitamins or in sodium shakers, or merely despatched back to the sea (recycling). Using the power of nuclear reactors to extract this hydrogen from the sea, to then input that into fuel tissues to energy advanced airplanes, tanks, ground autos, and the enjoy, is clearly higher on the R & D priority number of the navy.

Types of Solar Panels -

By
article
Published: July 16, 2011Posted in: GeneralTags:

Which kind of   of Solar power system panels  are there? 

When  you have ascertained what size solar panel system  you want , the next step is to decide  what kind of solar panels will meet your household requirements  . This should not be a decision based purely  on budget  , because power efficiency , longevity, company warranties  , and space needed are all important factors. Allot of the time  people base there buying  decisions on price only and ask why no-one picks up the phone from the “fly by night company” you bought your solar power system  from when in  3 years your inverter dies or your output is halved or significantly reduced . But its also important to  understand  that there are different qualities of panels on the market and you should compare “apples with apples”, “not apples with oranges”. So although there are 3 main types of panels ; Mono crystalline,Polycrystalline, and thin-film or Amorphous  its important to recognize the advantages and disadvantages of both . If your main hurdle for purchasing panels is price, then I suggest you compare “like with like” so its silly to  judge the price of Mono with the latest Amorphous panel and make your purchasing decision based from price alone.

One of the most important distinctions to make regarding Solar panels is the different Wattages available. Watts are related to the output of each panel, so a 200W panel would output 200 watts per hour. Expect to pay  twice  the price of a 100W  solar panel  .

Warranties

 Solar power panels come with a performance warranty that may last up to 25 years and a guarantee of five to ten years. As well, installers can provide a warranty on installation work  , typically five years. So ask your solar retailer who is providing the warranty–the importer or the manufacturer–and what happens if something breaks or malfunctions . 

There are three main types of solar panel available, each with their own benefits.

Mono crystalline cells 

Mono crystalline panels are proven and  trustworthy  technology, used over the past 50 years and still popular today . They have the  highest  conversion efficiency, at 12-18% of all sunlight. Because these have the highest power to size ratio, they’re  one of the best option if you’ve  have  limited roof space. They also degrade very slowly, generally losing 0.25 – 0.5% per year. Their total lifespan  can be 25 years, even up to 50 years if looked after .
Disadvantages: Mono crystalline cells sometimes don’t  perform as well as other  solar panels  in shady conditions and they are quite fragile. They are more expensive to manufacture due to their complexity.

Polycrystalline cells

Polycrystalline compares well in performance and longevity to mono crystalline, and provide efficiency of 12-13%. Well known brands include  Sharp, Kyocera, SX & BP  .
Both crystalline panels have great longevity (around 25 years). Both work optimally at 25oC and will lose some efficiency at higher temperatures (over 50oC) – common in our  warmer months .

Amorphous Thin Film

Thin film panels  mostly  have a much lower efficiency at 6%, however,Cadmium Telluride Thin-Film panels (CdTe) have progressed to 11% efficiency. These are more suitable for inland Australia conditions where space is no problem  and temperatures are  above average  . Amorphous panels  will never  lose energy in higher heats.
Disadvantages are: expected lifespan is less, there is a 3-6 month breaking in period, and they  generally  require 2-3 times the roof space for the same output of crystalline cells.
When choosing, remember to focus on the goal of recouping your initial costs through savings in electricity . The more efficient and higher Watt panels will do this  much quicker  .  However, if you are  considering looking   at solar farms in Outback Australia where temperatures routinely get above 40 degrees Celsius and there is a bit of cloud cover as these panels work much better in the shade also then these panels may be for you .

Advantages of Solar Power – Exactely how much Effective Can certainly this Supply of Electricity Could Bring to You together with Your Household

By

Published: June 25, 2011Posted in: GeneralTags: , , , ,

With the economic situation spiraling down worldwide, we look the advantages in favor of saving dollars as we can find. Perhaps the utmost plus factor of solar power is reducing expenses of money on our electricity usage. A collection of solar thermal antenna in the form of solar panels collectors help reduce 100′s of dollars in the cost of power used to power our homes. These solar panels gather the sun plush with a process of changing and inverting such rays, gathers the electric supply we have to generate electricity to each of our machines as well as to heat up and have light in our homes.

Because nature has given to all of us the knowledge to invert the rays of the sun to solar electricity, she has given us all a free access to energy. Just think, never again to pay an expensive electric bill on a regular basis. We can take advantage of the open access to sun’s rays to use in all our homes and also what we don’t use all of us can also store in a battery to use on days when the sun is hiding behind a cloud, or during the night. We have had a demonstration of what solar energy can offer, at times when we all make use of all our calculators and our swimming pool. That calculator that powers off and on with no mouse click. When the sun rays supply heat to the water in the pool, you should use a solar cover at your pool in order to preserve the heat in the water.

Setting aside some moeny is also only some of the advantage of making use solar power panels. In saving power we also are sharing our function in preserving the nature. Most of our idea today aren’t only concentrated on economy and reducing expenditure, which is important and matters most. We also are anxious about saving Mother Nature and we can do so by saving as much power as we can. Using natural geothermal energy instead of artificial processed electricity sourced out by the electric power company is a great way to start. When you are laying around at the pool these days, enjoying the warm water in the swimming pool and taking pleasure of your sun tan, imagine what can the rays of the sun could possibly offer your office and your expenses.

Constructing The Solar Wind Hybrid System

By
article
Published: June 24, 2011Posted in: GeneralTags: , ,

It could be the best of both worlds. A Solar Wind Hybrid System utilises both Solar Energy and Wind Energy. By doing a combined system, it will be cheaper to build versus building the two individual systems.

In the United States, wind speeds are negligible in the summertime, when the sun is at its warmest. In winter, the winds are more potent, while the sun may be hidden behind clouds, during a storm. With a Solar Wind Hybrid System, you might produce continuous power or electricity, every day, all year long.

What Will You Have To Build?

With a Solar Wind Hybrid System, you will be demanded to build and install:

1. The Solar Panels either on a house, building or on a stand.

2. The Wind Turbine can be located in an open area.

Both the Solar Panels and Wind Turbines should be sized to supply enough power to the building structures. So on a cloudy day, the wind turbine can supply enough electricity for the property.

What Parts Coincide With Both Systems?

The following parts are used with both systems. They comprise of:

1. Rechargeable Batteries store the excess energy. You may need several batteries at the proper size. You will also need battery boxes, which prevent any acid from leaking out.

2. Electronic Controllers can operate the system automatically. They provide consistent power to the site.

3. DC to AC Converter. Since the building runs on AC, the DC Power from the solar panels and wind turbines has to be converted to AC.

Where Possibly Could You Put The Solar Panels?

Solar Panels can fill up a building roof. If you need more power, you may erect the solar panels on a separate structure. You could also use concentrated solar power. Here, mirrors tilt around a pole and these mirrors direct the sunlight to a point on top of the pole. This concentrated solar power will contribute more electrical energy to your project.

How Can You Build The System?

You can install and build the entire Solar Wind Hybrid System. You can also build the system in stages. Try doing the windmill first, and build the components to tie into the building. You could make use of a generator, in this first stage, for additional electrical power. Then, add solar panels as a second stage.

The Solar Wind Hybrid System is an ideal way to go, if you own an independent system in a rural area. This system supplies continuous power all year long.

What Is A Green Energy Company?

A Green Energy Company can help design, build and maintain wind and solar energy products. They make the homeowner’s job easy, by doing most of the work. In the end, the homeowner saves money in a reduced or eliminated electric bill.

What Do They Do?

Green Energy Companies are either Solar Energy or Wind Energy.

1. Solar Energy

- design the project

- order the solar panels

- inspect the contractor’s work during installation of the solar panels

- coordinate any tie-ins with the utility companies

2. Wind Energy

- standard design for the windmill

- order the windmill

- Look at the contractor’s work for the drill shafts and substructure.

- coordinate installation of the windmill

- coordinate the final inspection

Green Energy Companies are materializing everyday. More people are getting involved with the planning, designing, constructing and operating solar and wind systems. For the economy, ‘going green” can create employment opportunities for business people, engineers and contractors.

You Can Do It!

You can build your own Solar Wind Hybrid System. Anyone can do it and you can save money.

Great Luck!

How to Use Your Solar Path Lights to Charge Batteries

By
article
Published: June 20, 2011Posted in: GeneralTags: , , ,

Are You Ready For When The Electrical Grid Goes Out?

Are you aware that you can charge your “AA” rechargeable batteries with those eerie solar lights glowing beside your driveway? Yes, you can! What does it require? Next to nothing – they have already been designed for charging batteries.

Solar garden or landscape lights generate little real light; however, they do have two quite prominent features:

1. They are inexpensive to buy

2. They do an admirable job as simple solar charging devices for AA size NiCad (Nickel Cadmium) or NiMH (Nickel Metal Halide) rechargeable batteries.

As of this moment, Amazon.com offers Moonrays 91225 Solar Powered Plastic Path Lights in a package of 10 for roughly $30. I haven’t used this particular model but most are about the same.

These outdoor solar lights normally are powered by one or more replaceable “AA” sized NiCad batteries – which naturally means it will also charge them.

For $30 I get a charger for at least ten “AA” batteries. Not too bad.

These solar patio lights may be more cosmetic than functional; but if your regular battery charger is missing or broken, they might bail you out and more than justify their cost. These battery-charging solar lights could prove an important part of your survival gear; if you get power outages, your usual battery charger will be useless. Using that solar light to charge batteries may be your only option. You might view it as the smallest possible solar power emergency backup system.

If you already have them functioning in your garden, that’s okay but keep in mind that they will keep on cycling every day and even the best rechargeable battery wears out in a year or two at this rate.

I prefer to keep a backup set and not use them at all until needed. Of course the batteries still need to be checked and charged every so often and not left to sit for long periods uncharged.

Be sure to use the kind of batteries recommended for the type of solar garden light that you purchase. Most recommend NiCad but some will take either.

There is a difference between how NiCad and NiMH batteries are charged and it should be okay to charge NiMH batteries in any of these solar light chargers because they charge so slowly. These are basically “trickler chargers” and seem unlikely to be able to damage any battery.

Because of the extremely high capacity of NiMH batteries, it might take several days to fully charge them, depending upon light conditions. However, I haven’t tried it yet.

Another key point: Most of these lights (perhaps all of them) have a photo-sensitive switch to turn the light on and off at dusk and dawn. If you buy your solar garden lights just for producing light, it’s not a problem. But if you are going to use them as dedicated emergency chargers, you should avoid discharging the battery by disconnecting the bulb.

This is a simple way to make sure you can recharge small batteries.

To do the heavy lifting of recharging my heavy-duty 90-lb lead-acid batteries, I built two 65 watt solar panels out of cheap grade “B” solar cells, plywood and some acrylic sheeting. I used the design from the GreenDIYEnergy instructional videos.

It was easy to make and I’ve had no troubles with it. You may want to take a look at the Guidelines for Sizing a Solar System for your own project needs.

Solar Energy Advantages and Disadvantages

By
Daniel Rider
Published: June 17, 2011Posted in: GeneralTags: , , , ,

Although solar energy has its disadvantages, they are vastly outweighed by its advantages. At least, they should be. It is relatively efficient, compared to other renewable energy, and it is certainly relatively cheap compared with them. Also, individuals are able to get solar power for their own property.

Why should you be interested in having solar panels installed though? We can cite two major reasons that you might be interested in doing that. From a pragmatic point of view there is the financial reason that you can save money on your energy bill by generating your own energy. With the government’s Feed in Tariff scheme you will also actually be making money. Then there are the long term reasons for the planet as a whole, which are that fossil fuels damage the environment with the pollution that they create.

Arguably the most important of those two reasons is the environmental one. If the world is able to transition to renewable energy there are two nightmare scenarios that we will be able to avoid. The first is that of global warming which, if the science behind it is correct, could lead to catastrophic climate change which might even make our survival on the planet untenable. The second scenario is that we will, eventually, run out of non-renewable energy, and if we are not using sufficient renewable energy by that point then we will not be able to sustain the current population of the planet.

Given that we are facing such dire consequences, it is tempting to think that we should be using more solar power, no matter how much it costs. While that is fair sentiment, it is not practical. If there were some situation where the only way to survive would be for everyone to own a submarine, then unless we found a way of making submarines quickly and cheaply that would be impossible. It is the same sort of situation with solar panels, so the financial challenges have to be met before the environmental ones can be overcome.

At the moment, however, there are many challenges to be faced in terms of the solar power that we are using. First of all, it is not very efficient. That means that for all the energy that the solar panels could potentially be getting from the sun, much of it is being wasted. That is why research is always being done in to how to make solar cells more efficient.

As already stated, the issue of how expensive solar installations are is also an important one. Although the government cannot really just give people free solar panels, they are doing what they can to make buying them a better investment, and therefore more attractive to people. Although this does not solve the problem that many people still will not be able to afford the installation costs in order to take advantage of the Feed in Tariff scheme.

When these two problems of efficiency and expense have been solved, we will have come up with a solution to our energy concerns. That’s because solar panels are not only able to power our homes, but they are also able to power just about anything else because they can be put anywhere. There are prototype cars that are being powered with solar cells, for example. Even the energy that we need to travel could be acquired from the energy from the sun eventually, therefore.

The key to bringing about these changes, transitioning from non renewable energy to solar energy and other renewable forms, is individuals. If we start demanding more and more solar power, then companies will respond by creating more solar cells, and doing research into making them more efficient. There will also be competition between these companies, driving down the price and eventually making it affordable for everyone. This is how we will be able to avoid global warming without an economic collapse.

Solar Energy Advantages

By
David Brown
Published: June 16, 2011Posted in: GeneralTags: , , , ,

If someone told you that the future of the human race depended on our using more solar energy, you might think that they were crazy. If that were the case, then surely the politicians would be making more fuss about it, surely there would not be objections on aesthetic ground to sites being created, not if it is so important. However, through applying a little bit of logic, we can see that it is actually that important.

At the moment our way of life is based on the fact that we are able to get cheap energy. That is, energy which is relatively cheap. No longer do we have to rear, keep and feed horses as a mode of transport, for example. We might think petrol is expensive, but that’s nothing to having to own a horse to get around. If this cheap energy runs out before we have an alternative in place then the planet will no longer be able to sustain the population of the planet as it is. Unfortunately the cheap energy comes in the form of fossil fuels, non-renewable energy, meaning that it will run out. Before that happens it will become more expensive, and there are signs of that happening today. That is why we can say that renewable energy like solar power is actually so important.

If we want to avoid these problems, which will come from the non-renewable energy running out, then we have to transition to renewable energy like solar power. Of course this has not even mentioned the dangers that the effects of global warming can have, which can also be very serious. The way to combat this as well though is through the use of solar panels.

Two of the reasons that solar panels are so popular is that they are versatile and they are relatively efficient. Solar cells are scalable, so you can have huge ones that you put in a desert, and they work as a solar power plant. Then you have the small ones that can go on things like pocket calculators. But you also have what is perhaps their most useful size, the ones that can go on the roof of a house.

It might not seem as if you are making much of a difference on your own by getting solar panels for your roof. Actually though, you are exercising true democratic power, you are literally and figuratively taking the power for yourself and changing the world one little piece at a time. It is all any of us can do, and it is the only way that the world changes. Don’t think of yourself as being on your own though, you can connect to all of the other people that have done the same thing.

There are quite a few people who have taken the plunge and got a solar installation, but of course nowhere near enough. What we have been able to observe, however, is that when the government brought in the Feed in Tariff, which made solar panels a better investment, more people started buying them. You could take that to mean that people are greedy and only care about the money, or you could view it that they wanted to be able to get them but they were too expensive before.

Perhaps, however, you do not think that expense should come into it when we are talking about the survival of humanity. However it is not something we can afford to ignore, we just have to hope that solar power can be made even more efficient, powerful and cheap so that it can take over from fossil fuels as soon as possible.

The best thing about solar energy is probably that you have the opportunity to directly get involved in using it. You can stop being a part of the problem, reduce your carbon footprint, and make money at the same time when you get solar panels for your property.

To have installations of solar energy, and for more information, author David Brown also writes at Solar Energy UK.
