Energy saving measures

Energy saving measures

Today the energy demand is more than the energy generated from different conventional and non conventional methods. Here are some of the energy saving measure which will significantly reduces the demand, so that we can all live comfortable with available energy or power
1. Switch off lights and fans when not required
2. Use minimum lights required for the work table and switch off other lights

3. Whenever sufficient day lighting is available, switch off excess lights in corridors and verandahs

4. Whenever sufficient day lighting is available, switch off excess lights during the lunch hours
5. Use one AC only in rooms which are fitted with two ACs. Switch off ACs when the occupant is not in the room

6. One will use 3 to 5% less energy for each degree the AC is set above 22 degree Centigrade(71.5 F) Set the thermostat of the room of AC at 25 Deg. To provide the most comfort at the least cost
7. Using Ceiling room or fans allow you to set the thermostat higher because the air movement will cool the room

8. Turn off your computers / office equipment when not in use
9. Screen savers save the computer screens, not energy. Start-ups and shutdowns do not use any extra energy nor are they hard on your computer components. In fact, shutting down computers down when you have finished using them actually reduces system wear and saves energy

10. Setting computers, monitors and copiers to use sleep mode when not in use help cuts energy cost by approximately 40%

11. Use photo copiers during specific timings only. Collect various copying works and carry out during the specific timings only. Avoid frequent on-off switching since more power is drawn during every start up

12. Battery chargers, such as those for laptops, cellphones, and digital cameras, draw power whenever they are plugged in. Switch off, pull the plug and save energy
13. Avoid incandescent lamps which consumes more power.
14. Ensure monitoring and follow up of above measures by all concerned.

Wireless Energy Transfer

Wireless Energy Transfer

To the energy transfer is taking place through wire or conductor. With wired power or energy transfer, we can easily transmit energy of very low to extra high value. But for some places it will be very useful if the energy transfer occur without wire is required. There are different concepts used in the field of wireless transfer technology. The one more thing is that the % of amount of energy transfer is main criteria to transfer between places of very large distances.
These are

1. Transformer coupling
Energy transfer between two coil through magnetic fields
but in this method, distance between two coils should be too close.

2. Resonant induction coupling (Evenescent wave coupling)
Electro magnetic wave in a high angular waveguide is called as evenescent waves which carry no energy, when if a proper resonant waveguide is brought near the transmitter then a tunnel is formed to the power drawing waveguide which can be converted in DC using rectifier circuits.
A prototype model is achieved with 5 meters of ranges with this method.

3. Radio and microwave energy transfer:
with this method a long range is possible. In this method microwave is sent to the long distances and can be received through rectenna which extract microwave energy back to electrical energy. But the problem with this methods is that the diameter of antenna should be order of km.

4. Laser beam transfer
In this method, laser is beamed to the photo voltaic cells which extracts the electrical energy

5. Electrical conduction method
In this method, while tranfer energy through wires or conductors, when the voltage reaches the breakdown voltage, the sorrounding medium start conducts, in this way the enegy can be transfered through air medium.

Though there are several methods available, in practical cases there is no device for transmitting power wirelessly with high energy capacity. But at low power transfer there are so many devices available in the market.

Flexible Organic solar cells

Flexible Organics solar cells
Solar technology have revolutioned the world with its flexible, light weight form of solar cells which are so flexible to use in almost all the applications. These organic solar cells are made of polymers. Such solar cells can be easily printed or painted in roof of the building or any vehicle to drive its engine.

Formation these cells:
The solar cell uses a carbon nanotubes complex, is a molecular configuration of carbon in a cylindrical shape. The name is derived from the tube's miniscule size. Scientists estimate Nano tubes to be 50,000 times smaller than a human hair. One nanotube can conduct current better than any conventional electrical wire.
these carbon nano tubes and combined them with tiny carbon Buckyballs (known as fullerenes) to form snake-like structures. Buckyballs trap electrons, although they can't make electrons flow. The falling of sunlight over these structure excite the polymers, the bucky balls will grab the electrons. Nanotubes, behaving like copper wires, will then be able to make the electrons or current flow.
Using this unique combination in an organic solar cell recipe can enhance the efficiency of future painted-on solar cells. Once this is mass produced then this process become an inexpensive energy alternative for households around the world.
Merits of this Novel solar cell

This is so light weight, more efficiency and robust in nature
Uses less silicon and so it is in expensive.
It can be easily embedded with other applications
It can be used to power GPS systems and so on

Ultimately, it gives energy with 100% green technology. We all will be happy when such a technology is implemented in our usage.

Latest in LED Technology - Organic LED

Latest in LED Technology - Organic LEDs
Conventional LED:

LEDs are known as Light Emitting Diodes. Light-emitting diodes are made up of using semiconductors such as Gallium Arsenide, Gallium Phosphide, and Gallium Nitride, have been around since the late ’50s. The main application of LEDs are indicator lamps, calculators, large advertising signs with high brightness. Limitation of LEDs Though such crystalline LEDs are not inexpensive, but it has its own limitation like integrating them into small high-resolution displays. L.E.D.’s work well in giant screens and advertising displays like those in Times Square, they cannot easily be used to create small, high-resolution screens for portable computers.

Organic LEDs – A breakthrough in LED technology

To overcome the difficulties faced by the conventional LEDs, the Organic LEDs has entered into the field. Organic light-emitting devices (OLEDs) operate on the principle of converting electrical energy into light, a phenomenon known as electroluminescence. They exploit the properties of certain organic materials which emit light when an electric current passes through them. In its simplest form, an OLED consists of a layer of this luminescent material sandwiched between two electrodes. When an electric current is passed between the electrodes, through the organic layer, light is emitted with a color that depends on the particular material used. In order to observe the light emitted by an OLED, at least one of the electrodes must be transparent. Advantages of OLEDs When OLEDs are used as pixels in flat panel displays, they give greater viewing angle, lighter weight, and quicker response. Since only the part of the display that is actually lit up consumes power, the most efficient OLEDs available today use less power. Because OLEDs are self-luminous, backlights are not required as in liquid-crystal displays (LCDs). OLEDs have very low power requirements and are thin, bright and efficient.

Applications of OLEDs
OLEDs have been proposed for a wide range of display applications including magnified microdisplays, wearable, head-mounted computers, digital cameras, personal digital assistants, smart pagers, virtual reality games, and mobile phones as well as medical, automotive, and other industrial applications. This OLEDs with its full color displays will replace today’s liquid crystal displays (LCDs) used in laptop computers and may even one day replace our ordinary CRT-screens.

Future scope of OLEDs
In OLEDs as crystalline order is not required, organic materials, both molecular and polymeric, can be deposited far more cheaply than the inorganic semiconductors of conventional LED’s. Patterning is also easier, and may even be accomplished by techniques borrowed from the printing industry. Displays can be prepared on flexible, transparent substrates such as plastic. These characteristics form the basis for a display technology that can eventually replace even paper, providing the same resolution and reading comfort in a long-lived, fully reusable (and eventually recyclable) digital medium.

Wind Energy Harvesting

Wind Energy Harvesting
Wind Energy is one among the Renewable energy sources. Wind energy is also available plenty world wide. Once all the conventional energy sources are exhausted, the alternative sources of energy are wind, solar energy and so on.
This wind energy is normally extracted by using a Wind mill which are installed at high or low speed wind directions. Wind mill comprises of a generator coupled with blades, once the wind flows over the blades, it is rotated which in turn rotate the shaft of the generator, so that the power is extracted as electrical energy.

The amount power generation depends on wind speed, blade size, orientation of blades towards wind and so on. By properly using the converter systems, we can extract more energy with availabe wind mills.
These future energy sources will never exhaust and forever available to meet out our energy demand.

Efficient way of Solar Energy Harvesting

Efficient way of Solar Energy Harvesting
Solar power is available plenty in nature. Once the conventional energy sources are exhausted, one of the alternative energy source is solar power. Solar panels are normally available for extracting energy from solar sources. But the efficiency of converting solar power to electrical power is very low as well as costly. So it is required to extract the electrical energy from solar, we have to use efficient energy conversion systems so the more power from the solar can be obtained.There are so many methods to extract more energy from solar with high efficiency, one method is solar tracking system. In this method, solar panels will be rotated along the sun axis, so that more solar rays will fall over the panels, hence more solar energy during the days. In this method also we have to use motors and control circuits to track the sun.
Another method is maximum energy conversion system. From the V-I characteristics of the solar panel, it is found that for each solar light intensity, temperature and surrounding atmospheric conditions, at one point maximum power will be available. This point can be identified by through converter systems, i.e. monitoring the maximum current and voltage point, accordingly the firing angle to the converter can be controlled. At this point, the battery connected to the solar energy conversion system is charged. In this way maximum efficiency can be achieved.

Latest in Energy Meters

Latest in Energy Meters
Induction type Energy meters have been in use all over the world. This is a indicating type where we have to note down the meter reading accordingly the number of units of power consumption then billing is done. It is a time consuming for consumer as well as energy provided. What are the other types of energy meters to overcome this difficulty. I would like to share some of these types.
1. Digital Energy meter, Here the energy meter readings are available in digital which can be easily transmitted or received between consumer and energy provider
2. Digital Energy meter with prepaid card, Here the number of units of power can be purchased in advance from Energy provider as if it is used in Mobile phone, the power consumption can be done according to the amount available, then recharge the card again according to our requirement
3. The latest trends in this technology in the energy meter era is networking of energy meters. Here the each energy meter from the consumer is considered as a node and assigned a unique IP address. This is like computer nodes connected in network with unique IP address. In this way, a communication is made between the consumer and energy provider, so that each parameter like current, voltage, power, energy, number of units consumed and the tariff rate can be accessed from a single place (from energy provider side) and can be constantly monitored.
This technology will reduced the gap between the consumer and energy provider in turn save time and over cost. Benefits will be for both sides.
These energy meters are classified as web enabled, energy meter with embedded network, meter network with RS485 and wireless energy meters and so on.
