Early summers usually bring a pleasant relief from the bone chilling winters, but come April & May, the summer heat starts taking its toll, both physically as well as mentally. and when it’s a tropical climate, as in most parts of India, the hot days can be all together stressful. The energy levels of individuals go down and so does their productivity.
This is when the modern day Air conditioning comes as a God Gift. A very large no. of Offices, laboratories, hotels, public buildings are nowadays fitted with air conditioning systems. Centralized Air Conditioning Systems ensure cooling in every nook and corner of the working space.
While this all sound hunky dory, its not. Extensive air conditioning is synonymous to heavy power consumption (and wastage) leading to not just heavy electricity bills but also the dreaded frequent power outages. The next step is – of course – DG sets, to bring the desired comfort indoors, while puffing out clouds of black smoke with terribly high levels of sound pollution for the outside world and the environment to endure.
In the midst of saving ourselves from the fury of the nature, we are inadvertently attacking the nature more and more, which keeps returning even more furiously every now and then. One of the biggest points of concern thus is the impending danger due to the rising world temperatures (Global warming). So what shall we do to survive and survive with comfort?
Let’s not forget we have an immense source of energy in the very Sun that we’re shielding ourselves from. One answer is Generation of power using sun’s energy. It’s free and for now we can safely assume, unlimited. yes, solar energy can light up our homes and cook our food. but can it also cool our houses? The answer again is yes. Solar air conditioning, a revolutionary and upcoming technology, provides the answer.
Solar air conditioningrefers to any air conditioning (cooling) system that uses solar power. A liquid or a gaseous substance either accumulates on the surface of a solid, porous substance (adsorption) or is taken up by a liquid or a solid substance (absorption for providing the necessary cooling). in some processes supply air is directly conditioned, i.e. treated in terms of temperature and humidity
This thermally driven cooling and air-conditioning process is at the heart of every solar cooling system. The main principle of Sorption assisted Air Conditioning is shown in the graphic here. The solar energy is used to dehumidify the sorbent.
This is a 9 stage process. in Stage 1 to 2, Sorptive dehumidification of outside air takes place with simultaneous rise in temperature through the freed adsorption heat. Then the air is cooled in the heat reclamation rotor in the countercurrent to the exhaust air (stage 2 to 3). Air is further cooled (Stage 3 to 4) through evaporation-humidification; thus the air inflow to the building has a lower temperature and less water vapor than the outside air. in Stage 4 to 5 Heating of the air takes place, and if necessary addition of water vapor. Then during Stage to 6 building’s exhaust air temperature is lowered through evaporative cooling in the humidifier. This exhaust air is heated (Stage 6 to 7) in the countercurrent to the air inflow in the heat reclamation rotor. The exhaust air is further heated (Stage 7 to  through external heat sources (i.e. solar thermal system). Finally in Stage 8 to 9 Sorption Rotor is Regenerated through the desorption of the bound water.
Open and Closed cycle Air Conditioning Systems:
Open-cycle systems are more beneficial in buildings with high humidity loads and high air exchange rates. The installation of ducts for the supply air and the return air, as well as a heat recovery unit is required. in this, the outside air is dehumidified through sorption and is then brought to the desired temperature by heat recovery as well as direct and indirect evaporative cooling. usually dehumidifying is achieved in a rotor containing the desiccant material silica gel or lithium chloride, but increasingly liquid desiccants (desiccant material: lithium chloride) are being tried. in these systems the solar heat is required for the regeneration of the absorption/adsorption unit.
Closed-cycle desiccant evaporative cooling systems are based on the processes of Adsorption (based on solid desiccants like silica gel or Zeolites with water as refrigerant) or Absorption (where desiccants are liquid ex. material pairs of lithium bromide as desiccant and water as refrigerant, or water as desiccant and ammonia as refrigerant, where sub Zero temperatures may be required).
For cooling and acclimatizing of buildings, only solar-thermally driven processes are used.
In actual practice, solar collectors are used to convert solar radiation to heat that is then fed into a thermally driven cooling process or into a direct air-conditioning process. particularly in special applications, for example for cooling medicines in remote areas that are not connected to the grid, a photovoltaic generator transforms solar radiation to solar power that then drives a refrigeration process – usually in the form of a compression chiller.
There have been considerable developments in the field of solar-assisted heating and cooling and world over this technology is being rapidly tried and adopted.
Recently Solar thermal World Magazine reported that India’s latest and probably largest solar thermal based air-conditioning system went operational at Muni Seva Ashram (MSA) in Goraj, situated in the Vadodara district of Gujarat state in western India. A total of 100 parabolic dishes (Scheffler type) by the Indian company Gadhia Solar Energy Systems (GSES) – each 12.5 m2 in size – now supply the already existing 100-ton air-conditioning system of the 160-bed hospital at Muni Seva Ashram.

Performance of Solar Air Conditioning
While designing a SAC system and for judging its performance the key points to observe are the Load Profile, outside temperatures & humidity.
The decision whether solar cooling is sensible at all is influenced strongly by the load profile. Solar irradiation and cooling demand must be correlated, since the use of fossil fuels for the operation of the chiller is disadvantageous from a primary energy point of view and should be avoided.
In order to achieve the highest possible degree of utilization, applications that also require heat for heating water or for the heating system outside the cooling season must be explored. thus residential buildings and small office buildings are most suitable. If cooling is required throughout the year (process cold, server rooms) the solar cooling system can be used merely as a fuel-saver for conventional air-conditioning. in such a case free cooling directly through the heat rejection unit might be an option in the cooler seasons.
Heat rejection rate greatly affects the performance and efficiency of the chiller. in most systems the waste heat is released into the environment by dry coolers or wet cooling towers. The former are suitable for moderate climate zones that only occasionally have high outside temperatures (>30C). Wet cooling towers have the advantage that cooling water temperatures below ambient temperature can be obtained. However, it only works if the relative high humidity allows for evaporative cooling. in regions with a shortage of water it is also unsuitable. in addition, some countries have imposed strict hygiene regulations on wet cooling towers which make the operation of small systems economically unviable.
It is essential to be aware of the fact that boundary conditions other than the nominal conditions, can negatively affect the performance of the cooling machine. If the system is not designed for the nominal operation point, the relevant operating data must be requested from the manufacturer. Then, for example, a dry reverse cycle chiller can also be used in warm climates if the solar thermal system is adapted accordingly.
Utilization of efficient EC motors in the SAC set up helps to reduce the energy consumption. To further reduce electricity consumption, these should be controlled according to operating conditions and cooling demand. Depending on the respective local conditions waste heat can also be rejected of in other ways, e.g. through boreholes, swimming pools or ground water. Ideally the heat can be used in other places.
The Advantages of Solar Air Conditioning
In comparison to conventional, electrically driven compression cooling technology, solar cooling has a no. of advantages. these systems are most useful when the sun shines the strongest – in summers. The machines generally utilize environmentally friendly refrigerants, leading to lower green house gas emissions. in most cases water is utilized which, compared to refrigerants used in compression cooling machines, has no greenhouse potential. Significant power savings can result from the fact that these systems merely require auxiliary energy for the operation of pumps, heat rejection, etc. if the systems are designed correctly. in addition to cooling, the solar collector system can also provide thermal energy for domestic hot water preparation and heating support which leads to a further reduction of emissions. SACs are also ideal for hotels, supermarkets, schools, factories, and large office premises etc. furthermore, noise emissions are significantly lower since the machines work without compressors.
Solar based AC systems thus can offer a reasonable alternative to the conventional ACs. in addition to drastically reducing or even eliminating current air conditioning bill, in many regions, one can receive a huge cash rebate as well as a tax credit by powering his air conditioner with solar air conditioning systems. As of now, the capital investments are high but the system can justify its worth in the long run. It is just a matter of time when this technology would be mass produced, bringing down costs to affordable levels for the common man. and then, the days that pose the maximum cooling requirements shall be the very same days when maximum energy could be extracted from sun while pocketing all the resulting benefits. The choice would really be ours

Alternative energy sources, like the solar energy, are now gaining a widespread popularity due to their minimal environmental footprints and inexhaustible supply. since solar power comes from the sun and not from the Earth’s crust (like fossil fuels), it does not need to be mined, which has a damaging effect on the environment. and also, solar power releases very little amount of carbon into the atmosphere, hence a negligible footprint. and, as long as the sun shines, this source of energy is free and inexhaustible.
But how is solar energy harvested from the sun? what equipment is used to channel the sun’s raw power into usable energy? the answer to that is through solar panels. an assembly of individual solar cells typically made up of silicon wafers. It generates power by trapping the sun’s photons, or light energy, into these cells and converting them directly into electricity through the so-called photovoltaic effect. this electricity can then be used readily to power a house or any commercial building. but its generates only a little amount of electrical power. To gather more, arrays of solar panels can be mounted on roofs or open spaces to generate substantial amount of electricity to power our basic light fixtures, appliances and others.
Since they were invented, solar panels have been put into good use. Artificial satellites that are now orbiting the Earth are mounted with solar panels to power their basic needs for the purposes they were designed. there have been science fairs that exhibited solar-powered vehicles, in the purpose to find commercially available solar-powered cars. These, too, have solar panels attached to them. a company has even invented a solar-powered cellular phone, so customers can go virtually anywhere in the planet with adequate power on their phones.
In recent times, with the rise of the price of electricity, many residential owners opt to incorporate solar panels to power their homes. These panels are mounted on roofs so that they are optimally exposed to the sun. True enough, homeowners are experiencing substantial savings on their electric bills. in fact, during midday, when the sun is at its hottest, solar panel users even generate more electricity than what they need. When this happens, they are able to sell electricity back to power grades, an incentive that makes solar panels income generating.
Commercial establishments are also going solar. on their flat and wide rooftops (of offices or warehouses), they have a sizeable collection of solar panels that can power their daily activities. by harvesting solar energy on their own, they are almost independent electrically from power sources. since large companies consume great amounts of electricity, they have been able to save by using solar power. and, like small residential consumers, these companies are selling back electricity during peak production, allowing them to earn.
Solar power production has come a long way. and, along the way, it continues tom improve to produce cheaper, safer and more environmentally friendly solar power products. even the solar panels are getting a makeover. in a few years, we might have more cost efficient and more durable panels that work just as good as or even better than their ancestors.

A MERE two years after its introduction, the Nissan Leaf— the world’s first mass-marketed, affordable, 100-percent pure electric car—is already gaining headway into the global automotive market and is serving notice that zero-emission mobility is truly viable.
It will be recalled that the Leaf, which stands for Leading, Environmentally friendly, Affordable, Family car, was announced during the 2009 Tokyo Motor show along with a commitment from no less than Nissan CEO Carlos Ghosn that the vehicle would be delivered the following year.
True to his promise, the Leaf was introduced in Japan and the US in December 2010. To date, deliveries have also been made to customers in Ireland, the UK, Canada, France, Portugal, the Netherlands, Norway, Spain and Switzerland, with orders soon to be filled in Belgium and Denmark.
At this year’s Tokyo Motor show at the Tokyo big Sight, Ghosn reported that 20,000 units of the Leaf have been sold, making it the best-selling electric car in history.
“Nissan Leaf owners have driven nearly 57 million kilometers, saved three million liters of fuel, which translates into 7,300 tons of CO2 that have not been emitted. In 2012 we will begin production of Nissan Leaf in the United States. by fiscal year 2016, the Renault-Nissan Alliance will have sold a cumulative 1.5 million electric vehicles,” Ghosn shared during the opening of the Nissan booth last week.
The Leaf is a five-door hatchback powered exclusively by a battery, which means that it does not require fossil fuels to run and, more important, does not produce tailpipe emissions.
According to Nissan, the Leaf is capable of a top speed of around 150 kph, thanks to an 80-kw, front-mounted electric motor, which delivers an equivalent of 110 hp power and 280 Nm of torque through the front wheels. Power is drawn from an 86-megajoule laminated lithium-ion battery that weighs 300 kg. The battery is always the heaviest part of any EV, but the Leaf is able to keep a low center of gravity and high structural rigidity compared to other hatchbacks by locating it below the seats and rear foot space.
Recharging the battery is accomplished through either of the two charging receptacles on the front of the hood. from empty, the battery can be fully charged in eight hours by plugging a cable into a 220- to 240-volt outlet. Charging can also be done through any standard household, 120-volt outlet; however, Nissan says this type of charging is only intended for emergency charging. Fast DC charging is also an option and the battery can be charged up to 80 percent of its capacity in 30 minutes. One full charge is said to provide the Leaf with a range of 160 km but reports say that most owners rarely travel beyond 100 km in their daily commutes. The cost to run the Leaf is said to be 70-percent lower than a comparable gasoline-powered car. a separate 12-volt lead-acid battery is used to power up the computer systems and accessories such as the audio system, supplemental restraint systems, headlights and windshield wipers. Nissan expects the Leaf’s battery to last between five and 10 years of “normal use.”
Aside from its powertrain, the Leaf’s other centerpiece technology is “Carwings,” which allows the vehicle to send and receive data via a built-in GPRS radio. Carwings automatically connects to the nearest cell site, allowing it to determine the vehicle’s position and possible range on a map and which charging stations are available within range. The system also tracks and compiles statistics about distance traveled and energy consumption and produces daily, monthly and annual reports of these and several other operational parameters, which are displayed on digital screens. with the system, the Leaf owner can use a mobile phone to remotely switch on the air-conditioner and heater, and reset charging functions even when the vehicle is powered down. An onboard remote-controlled timer can also be pre-programmed to recharge batteries at a set time such as during off-peak hours.
Safety wise, the Leaf received a five-star rating (the highest) from Euro NCAP, which makes it a “real” car in the truest sense, which is probably why, since its launch, the Leaf has received various awards such as the 2010 Green Car Vision award, the 2011 European Car of the Year award, and has been named the 2011 World Car of the Year and the 2011-2012 Car of the Year Japan.
Apparently, the Leaf is just the start of something big from Nissan.
According to Ghosn, the carmaker is aiming its sights on a clean, connected, mobile society that demands the development of both vehicles and infrastructure. The time when an automaker could focus only on the vehicle is over.
“Look at the concept cars here today. these are not exercises in design fantasy, but viable transport solutions for tomorrow’s digitally connected, urban societies, where “smart houses” and “smart communities” support zero-emission mobility,” he said.
Part of the company’s exhibit is the Nissan Smart House, which Ghosn claims is able to harness the energy of solar panels and combine that with the power from batteries and fuel cells in a unique Leaf-to-Home charging system. The Nissan Smart House can connect and manage energy more efficiently and in better harmony with the wider community.
In what is perceived as a move to enlarge its following in the global market, Nissan unveiled two new versions of the Leaf, namely, the Leaf Nismo Concept and the Leaf Nismo RC at the current Tokyo Motor show.
“Nissan is the first manufacturer to have a purpose-built electric race car ready for eco-friendly motorsport. and the Nissan Leaf Nismo Concept takes inspiration from the aerodynamics of the race car to transform the Nissan Leaf into a road car—one without a trace of exhaust. We have delivered on our promise of mass-marketed electric vehicles and are now working on the next generation of connected mobility solutions,” Ghosn added.
The retail price of the 2011 Leaf in Japan starts at ¥3.76 million and $32,780 in the US. Most countries where the Leaf is sold have governments that provide tax incentives or subsidies for eligible buyers that reduce the effective cost of purchase below the retail prices listed by Nissan, which is why the vehicle won’t be available anytime soon in emerging markets such as the Philippines, where the incentives and infrastructure are not in place as of yet.
Don’t lose hope, though, as Nissan is committed to making it happen eventually.
Ghosn said, “Three years ago, we promised to take the lead in EV production and now we have the Leaf. Our next step is to make the EV a feasible consumer alternative, not a niche. We are undertaking a lot of initiatives in emerging markets to make cars affordable to people who can’t buy them.”

Staying cool throughout the hot, muggy summer months while giving the environment a break is attainable if you consider a solar air conditioning unit for your home in place of the electrical unit. the biggest advantage is that the power to cool your home is free
Can I cool my Home using Solar?
There are a few things you should consider before making the investment into a solar air conditioner, but the general answer to this question is yes
Homeowners should think about how much sun their geographical location receives each summer. Hot sunny climates are perfect locations for air conditioners powered by solar energy because the sun is out most of the time. However, for those cloudy days, a hybrid system can kick in to keep your home cool.
Decide ahead of time how cool you want to keep your home. also, you must consider the square footage of your home in order to determine the type of solar AC system you will need to cool your home.
Of course, as with any investment into your home, you will need to consider the cost, which can range between a few thousand dollars to as much as $50,000. Keep in mind however that an investment like this into your home will not only benefit you over the next several years financially, but will also reduce your environmental footprint.
What Types of Solar Air Conditioners Are available?
Researchers, engineers, and scientists are consistently discovering and revealing new technologies that will enable homeowners to power their homes more efficiently while being kind to the environment. Solar power AC units are in that category with new technologies emerging as knowledge of solar power increases all the time.
* Passive Cooling Technology
* Photovoltaic Solar
* Solar Dessicant
Why should I Switch to Solar Air Conditioning?
The reasons you should consider switching to a solar powered AC unit are pretty convincing. first, the sun’s energy is completely free the costs associated with cooling your home will be reduced significantly.
No chemicals are used to power a solar air conditioner, so both you and the environment benefit from clean, renewable energy cooling your home.
Several states in the U.S. offer cash incentives and rebates to homeowners willing to use solar power AC systems. You’ll automatically increase the value of your home by installing a solar AC system, which in turn increases the resale value of your home should you ever decide to relocate.
Are There Drawbacks to using Solar AC Systems?
Yes, there are a few, but the benefits definitely outweigh the drawbacks. Geographical locations that experience cloudy conditions more often than sunny conditions may want to consider adding a battery backup system. It’s an additional cost, but one that is essential if you want a cool home during cloudy days.
Minimal cleaning and maintenance is required for a solar air conditioner, which is the same as your electric one.
The cost of installing a solar cooling option may cost too much for some homeowners no matter how little time it takes to recoup the initial cost.
Overall, a solar air conditioner is something to consider if you’re interested in making your home more environmentally friendly and the idea of cooling your home for free sounds good to you

A recent but highly effective creation which has recently been introduced onto the Home DIY Energy market are Solar Air Heaters. in the same way that homemade Solar Panels and Wind Turbines have revolutionized the home energy market, Solar Heaters are now becoming an increasingly popular method for heating homes all over the world.
So how do Solar Air Heaters work?
Even I was amazed at the very simple and very basic looking details of how a Solar Air Heater actually works. there really is nothing complicated by these and even the build instructions which are also available, are easy to understand too
As previously stated, they work by incredibly simplistic methods and simply utilize the heat from the sun by capturing the sun’s rays and converting that energy into heat.
As sunlight enters through the unit, the sun’s rays are trapped and give off heat. in fact, the heat generated by these heaters can reach temperatures of up to 220 degrees so it’s fair to say they certainly generate plenty of warmth
As cool air enters into the system, it is in turn, heated by the unit. this warm air can then be directed into your home.
A solar panel is not required to run this system although they can be used if required to help power a blower fan or thermostat.
They are a genius piece of equipment and if made correctly, they can help heat your home, workplace or garage for many years to come.
A well built Solar Air Heater will provide a stable and reliable source of heat for many years to come and one of the greatest and most rewarding benefits will be realizing the significant cost saving to your heating and utility bill.

SPG Solar has finalized a new set of solar systems in California. the company, working with Quattrocchi Kwok Architects (QKA) installed a 1MW ground and rooftop solar system at Napa Valley Unified School District’s American Canyon High School and additionally installed a 620kW PV and 54kW solar thermal hot water system at Point Loma Nazarene University (PLNU) in San Diego.
the 1MW project in Napa is said to be able to produce up to 80% of American Canyon High School’s electricity at full occupancy. the solar panels, which were noted as being American made, are mounted on the school’s roof and on a fixed-tilt ground-mount system. They will produce over 1.1 million kilowatt hours of solar electricity per year for the school.
In addition to its Napa solar array accomplishment, SPG Solar advised that its solar installations at PLNU were celebrated with a ribbon-cutting ceremony. the company designed, engineered and constructed the 620kW system, which is spread across two rooftops and five solar carports. the system uses Kyocera KD 235W solar panels and features a PPA financed through Perpetual Energy Systems wherein PLNU will purchase the electricity produced at a predetermined rate for 20 years.
“PLNU strives to be forward thinking and take a leadership role in sustainability efforts and environmental stewardship,” said Dr. Bob Brower, president of PLNU. “the stewardship of resources is one of our core values. It was through the strong partnership with Kyocera, SPG Solar, Perpetual Energy Systems, and Adroit Solar that we were able to expand our solar portfolio.”
A 54kW solar water heating system by Adroit Solar was also installed at the PLNU campus. the solar water heating system is expected to provide around 940 gallons of hot water a day to student dorms while saving the university US$5,000 per year on utility bills. both PLNU projects, which combined feature over 2,600 Kyocera solar panels, are projected to create over 917,000kWh of electricity every year and save the university up to US$1.6 million over 20 years.

Sydney is the largest and most populated city in all of Australia. It is also the capital of new South Wales. Sydney is known as a global center for the arts, culture, fashion, commerce, music, entertainment, tourism, and education. It was home to the 2000 Olympic summer games and the 2003 Rugby World Cup final match. while it is known for so much, many people also know this thriving metropolitan city as a center for clean technology, including renewable energy, energy efficiency, and sustainability. here are just a few of the highlights of what Sydney has to offer the clean technology industry.
1 ) Sydney Energy Cooperative. as a not-for-profit environmental organization, Sydney Energy Cooperative looks to involve the community in all activities related to energy. The cooperative was created as public awareness regarding energy and environmental issues became the forefront of many discussions. However, with all the talk, there has been little action and the Sydney Energy Cooperative seeks to take those actions. It was established in 2007 by students studying photovoltaic and renewable energy engineering at the University of new South Wales. There are three main areas of activity – education, joint purchase of solar panels, and lighting installations.
2 ) BlueGreen Engineering. BlueGreen Engineering is well known company in Australia dealing with energy efficiency, renewable energy, and sustainable design. Their mission is “To provide cost-effective innovative solutions which reduce energy consumption and cost.” BlueGreen Engineering has been involved in a number of products to assist in reducing energy consumption, including solar systems, lighting, and HVAC systems.
3 ) EcoSave. EcoSave was established in 2002 in Sydney and is one of the largest water and energy conservation companies in the country. Today, EcoSave works with a number of metropolitan and rural communities in Australia as well as new Zealand to provide water and energy saving solutions. for example, their efficient lighting solutions include lighting control systems, light fitting replacements, light fitting refurbishment, and voltage reduction units for fluorescent lighting. Water saving solutions include flow control for taps, water recycling, water efficient showers, cistern retro-fits, leak identification, and water and energy metering consolidation.
4 ) Energy Efficient Building Sydney. for homes in Sydney that are interested in becoming more energy efficient, Energy Efficient Building Sydney, is the best company to call. they provide everything from energy audits to eco-friendly products, energy saving products, heating and cooling, insulation, hot water services, landscaping, water harvesting, geothermal capabilities, and even information about how to get in contact with architects and designers that are able to build energy efficient homes.
5 ) First Electric Vehicle Charging Station in Sydney. In May of 2010, Australian-based company Chargepoint launched the first electric vehicle charging station in Sydney. this charging station is located in Derby place, Glebe and is able to fully charge an electric vehicle battery in approximately three hours. With this being the first charging station, Chargepoint is now looking to create other stations in various other capital cities, including Perth and Melbourne. However, before these stations are created, the one in Sydney will be used as a “test subject” to see what the public response is like along with energy usage.
6 ) BP Australia. BP Australia is involved with the exploration and production of natural gas, oil, and liquefied natural gas, as well as the refining, transportation, and marketing of petroleum. However, BP Australia also has a long history of looking for measures that address current climate change, and therefore is always looking into the development of much cleaner fuels as well as low-carbon alternatives when it comes to power generation. for example, BP Australia has completed over 170 solar power systems for new South Wales schools and there are currently plans underway for another 75.
7 ) Easy Being Green. With so many Australians worried about the effects of climate change, Easy Being Green looks to help residents in Sydney attach the negative climate changes through a number of easy energy saving methods. Easy Being Green has been able to put a cap on over four million tons of carbon dioxide emissions a year, which is roughly equivalent to removing around one million cars from the roads. Some of the solutions offered include solar photovoltaic, solar hot water, and heat pumps for all residential homes.
8 ) Sydney Water’s Pledge to Renewable Energy. Sydney Water recently created their own Renewable Energy Generation Program to assist in its pledge to become a carbon neutral company by the year 2020. The objective of this program is to reduce carbon dioxide emissions by 54,000 tons annually. Through this project, Sydney Water installed five biogas cogeneration facilities, along with three hydro-electric generators at wastewater treatment plants and pipelines throughout Sydney.
9 ) 2010 Multi-Million Dollar Smart Grid Project. EnergyAustralia in June of 2010 rolled out a $100 million trial of a smart grid project known as Smart Grid, Smart City across 50,000 homes in new South Wales, including Sydney. this is the first commercial-scale smart grid in all of Australia. around 15,000 homes involved in the project will also have in-house displays and websites to allow them to track their utility use as well as their emissions levels.
10 ) Sydney Opera House Becomes more Energy Efficient. The Sydney Opera House, a multi-venue performance center that is easily one of the most recognizable landmarks in all of Australia, is looking to go green by installing a number of energy efficient measures. for example, the opera house replaced all the pumps of their air conditioning system with more efficient ones and changed the way in which seawater cooling is utilized in the air conditioning system to allow the equipment to work much more efficiently. not only that, but the opera house is also starting to replace all their lighting with much more energy efficient lighting, including the utilization of LEDs.

A solar air heater is a great way in which one can have a realistic DIY project with excellent results. In many climates heating is the dominant energy need most of the year and standard sources of energy are just not going to cut it for a sustainable future, or a sustainable checking account for that matter. Solar air heaters will heat your house better and cheaper than current oil heaters, acting as the perfect substitute to mitigate your energy needs.
There are two basic types of active solar air heating systems based on the type of fluid-either liquid or air-that is heated in the solar energy collectors. The basic principle of any solar design is that you are using a heat exchange method to warm colder air and reduce the capacity of conventional systems to perform the same task. Solar air heaters are one of the most cost effective methods for reducing your electricity loads and can be incredibly simple to implement.
A solar air heater for your home is similar to what the electric motor is to a hybrid vehicle. used in conjunction with your existing heating system (oil, gas, wood pellets, wood, dilithium crystals, etc) it will decrease your fuel consumption by as much as 30%. now, if in the face of rising energy costs, environmental crisis, and an increasing degree of war over conventional energy systems; if this does not get you excited to implement it, then I don’t know what will.
A solar air heating systems creates a warm, soothing feel by using air as the working fluid for absorbing and transferring solar energy. Simply put, air is sucked into the warmer part of the vent leading to the enclosure and warmed by the heated material and brought back into the living space.
Solar air heaters are the most economical and most practical way to reduce your utility bills by using free solar thermal energy to warm the air inside of your home or business. Photovoltaic panels are making a comeback on the market place, but are still at a higher price than the average customer is willing to pay for. when it comes to the most bang for your buck, solar air heating is a fantastic alternative to your current heating source.
A solar air heater can be 25 times more cost effective than solar electric (PV) systems, and the systems are excellent DIY projects. Even if you have the least bit of construction knowledge there are several resources available to assist you. You already have proof you can do it by the very fact you are reading this article and taking the first steps towards your energy independence.
Installing a solar air heater is done in 6 simple steps. first, you must frame and fit the box for the enclosure; 2nd, paint (if you are aesthetically interested) and add screen mounting boards; 3rd,Mount the boards to the wall and seal, 4th, cut vents into the wall inside the enclosure (typically only about a 2×4 deep); 5th, install the metal window screen; and finally, install glazing and vent valves. while this may seem like a foreign language to you, I assure you that it is not only possible, but inexpensive and time efficient to implement.
The solar air Heaters collector can be as simple as painting the sun side of the thin foam panel flat black, or for a more efficient collector use a sheet of ten-thousandths aluminum (available as scrap). it really is that easy to begin to generate your own energy. Often people get confused when they think about generating energy as generating an active current of energy, when in all reality, reducing your current energy consumption is achieving the same goal.
