Discom Tata Power offers 50% discount on 5-star ACs in Delhi

NEW DELHI: Aiming to bring down power consumption in national capital, Tata Power Delhi Distribution Ltd (TPDDL) has launched a scheme offering up to 50 per cent discount on energy-efficient air conditioners.

The scheme would be available for 20,000 customers on first-come-first-serve basis.

Only the customers having an average monthly consumption of up to 1,200 units per month during April to September 2014 can avail this scheme, TPDL said in a statement.

Under the scheme, TPDDL consumers in North and North-West Delhi can get discount of 50 per cent on BEE 5-star rated ACs, Inverter ACs in exchange of their non-star ACs.

It is applicable for both window and split ACs of 1 & 1.5 tonnes.

The scheme is available on various models of ACs from leading Brands such as Voltas, Hitachi and Godrej.

TPDDL CEO and MD Praveer Sinha said: "...we have been constantly advocating energy conservation schemes. Our demand side management schemes not only aim to reduce power consumption but also help customers in reducing spending on their electricity bills."

The scheme has been targeted at households as the domestic sector accounts for almost 50 per cent of energy consumption in Delhi and ACs power consumption is a key component of the same.

TPDDL consumers can avail the scheme against their CA numbers (one AC per CA Number) mentioned in the electricity bills.

Fossil Fuel Reduction Strategy

There are three ways to prevent pollution due to dirty, fossil-fueled energy from entering our atmosphere: efficiency, conservation, and clean energy.  To some this is very obvious, but sometimes it helps “energy novices” to go over the differences so they can better plan their energy strategy and strengthen their ability to visualize energy.  The better you know your enemy , the easier it is to defeat (fossil fuel energy is our enemy here people).
Efficiency
Energy Efficiency means using less energy to get the same job done.  A CFL (compact fluorescent light)  is the perfect example of this.  As I showed in my lighting cost comparison between CFL’s and incandescents post, a 14 Watt CFL light bulb uses about 4 times less energy than a 60-watt incandescent bulb.  But while it uses much less energy, it puts out the same about of light, meaning that CFL’s are way more energy efficient than incandescent.
Other examples of energy efficient products are shown with the Government’s Energy Star program.  These are appliances that meet a certain level of energy efficiency.  Examples of energy efficient products that could save you a lot of energy due to superior design are refrigerators, washers/dryers, heating/cooling equipment, and other appliances that are used daily.
Conservation
While Energy Efficiency involves using energy smarter, Energy Conservation means not using energy at all.  As Amory Lovins says, Negawatts (not using energy at all) are the cleanest form of energy out there.  Examples of energy conservation in the home are turning off the lights (manually or using lighting controls) or turning off appliances when not in use (you can even use an automatic timer) or programming your thermostat to come on less when you don’t need AC or Heat.  Another example of energy conservation is insulating your home so your programmable thermostat controlled energy efficient furnace doesn’t have to work as hard to keep comfortable.  Like layers of clothing help you keep warm in winter, energy conservation layers (more insulation + programmable thermostat) help you prevent that much more fossil fuel energy from being used in the first place!
I’ve even shown in one post how energy conservation is a better investment than the stock market!
Clean Energy
Once you have installed energy efficient devices in your house and you have learned how to conserve the energy that you do use, the next step is using clean energy when you have to use it!
Clean Energy is energy that doesn’t pollute and is renewable.  The cleanest forms of this energy are Solar power and Wind power (which in itself is a form of solar power –> sun heats air, which causes temperature differentials, which cause wind).  Installing Solar or Wind systems can be expensive up front, but there are Federal tax incentives, State tax incentives for many, and sometimes even utility rebates.   While your very own Clean Energy generating system may be a longer term goal for some, it is definitely a pillar of getting off the fossil fuel strategy.
In a few years I hope to get a plug-in electric vehicle.  The motor powering the car will be energy efficient and by driving it I will be conserving gasoline (because it wont use gasoline, it will use electricity as it’s fuel) made from oil that came from the middle east.  I hope to eventually power the plug-in with clean energy from solar panels installed on my roof.
Getting our society off fossil fuel energy is not going to be easy.  It’s going to need a change in attitude by the public, a large amount of education, and the help of many leaders to show the “holdouts” how rewarding it can be to help lower our dependence on fossil fuel.   Let’s install efficient devices, start conserving as much as possible, and look at installing clean energy now.  Doing this will clean our skies, improve our national security, and fatten our wallets.
Sounds like a good strategy to me.

"Turning Trash Into Power"-Generate Natural Gas with Bacteria

HOW IT WORKS: In the process, food waste is collected from restaurants and institutions and then fed to bacteria that thrive in low-oxygen environments. It's called anaerobic digestion, a naturally occurring process of decomposition. One type of bacteria turns carbohydrates into simple sugars, amino acids and fatty acids. A second group of bacteria eats those compounds and turns them into hydrogen gas, carbon dioxide, and acetic acid -- the primary component of vinegar. Then a third group of bacteria takes those broken-down compounds and turns them into methane and carbon dioxide. Between 60 and 80 percent becomes methane. The methane can be used as fuel for an internal combustion engine that provides electricity.
TYPES OF DIGESTION: Anaerobic digestion is not the same thing as human digestion, since the type of bacteria that produce methane don't live in the human digestive tract. Industrial anaerobic digesters can also harness this natural process to treat waste, provide heat, and increase nutrients in soil. They are most commonly used for sewage treatment and for managing animal waste.
BENEFITS: The goal of SMUD is to obtain 20 percent of its electricity from renewable sources such as wind, solar, and biodegradable matter by 2011. Currently SMUD derives 10 percent of its electricity from renewable sources, of which biomass accounts for 2.5 percent. The UC-Davis digester would keep food and other biodegradable waste out of landfills; food leftovers account for 18 percent of a landfill's contents. One tone of leftover food can produce enough fuel to power 18 homes for one day.
WHAT ARE EXTREMOPHILES? An extremophile is any microbe that thrives in extreme conditions, such as temperature (extreme heat or cold), pressure, salinity, low oxygen environments, or high concentrations of hostile chemicals. Most extremophiles belong to a class known as archaeobacteria, but certain species of worm, crustacean and krill can also be considered extremophiles.

Waste-to-energy

Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of creating energy in the form of electricity or heat from the incineration of waste source. WtE is a form of energy recovery. Most WtE processes produce electricity directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels.

The energy content of waste products can be harnessed directly by using them as a direct combustion fuel, or indirectly by processing them into another type of fuel. Recycling through thermal treatment ranges from using waste as a fuel source for cooking or heating, to anaerobic digestion and the use of the gas fuel , to fuel for boilers to generate steam and electricity in a turbine. Pyrolysis and gasification are two related forms of thermal treatment where waste materials are heated to high temperatures with limited oxygenpressure. Pyrolysis of solid waste converts the material into solid, liquid and gas products. The liquid and gas can be burnt to produce energy or refined into other chenmical products (chemical refinery). The solid residue (char) can be further refined into products such as activated carbon. Gasification and advanced Plasma arc gasification are used to convert organic materials directly into a synthetic gas (syngas) composed of carbon monoxide and hydrogen. The gas is then burnt to produce electricity and steam.

What kind of indoor artificial light should you use?

On average, older people need about three times as much light as younger people. People with glaucoma often require much higher light levels, while there are conditions such as central cataract where lower light may be better. The quality and quantity of the light needed for comfortable, useful vision becomes particularly important when vision is impaired.

Glare results when light (natural or artificial) shines directly into your eyes or reflects off a shiny surface. When arranging a room to be used for reading or working, do not face the windows. Seat yourself so that windows are behind you or to your side. If that is not possible, use blinds or shades to control the light during daylight hours. Light from lamps or fixtures should be positioned directly onto the task (book, newspaper, playing cards, hobby/craft, etc.). Gooseneck, adjustable arm, and clip-on lamps offer good flexibility. In dimly lit restaurants, use a pocket flashlight. When reading or working outside, use a visor to shut out sky light glare.

Incandescent light is the thermal radiation emitted by a hot object such as the filament of a light bulb or the surface of the sun. Actually daylight is a form of incandescent light. In a common incandescent light bulb, an electric current flows through a tungsten wire, which gets heated and emits thermal radiation. Like all incandescent bulbs, a halogen lamp creates its light as visible thermal radiation from an extremely hot tungsten wire.

The Chromalux Bulb is made of special composition glass that is not colored or coated, but instead contains Neodymium, a rare earth element. This element is able to absorb yellow - as a result, the light appears whiter (in contrast to yellowish hue of the common bulbs). Contrary to claims, these bulbs do not even come close to being full spectrum, or duplicating sunlight. The only difference between these bulbs and normal bulbs is in the amount of yellow light emission.

Fluorescent tubes use a non-thermal radiation process to produce light. This is the only type of lighting that can come close to being 'Full Spectrum'. A type of fluorescent bulb is now available as a direct, screw-in replacement for some incandescent bulbs. They consume from one-sixth to one-tenth as much electricity, radiate very little heat, and, although expensive, last about ten times as long as the conventional incandescent bulbs. In addition, these modern tri-phosphor compact fluorescent bulbs provide light very close to the quality of incandescent. They provide excellent color rendition--food looks natural, colors look normal and offer a “comfortable” atmosphere for most people. There are considerable differences in the light spectrum emitted by the sun and artificial light sources.

REDUCE CARBON FOOTPRINTS

Easy Ways To Reduce Your Carbon Footprint

Your “carbon footprint” is a fancy name for measuring how much carbon dioxide you, er, produce. Whether or not you believe carbon dioxide is the cause of global warming or not, it is harmful to the environment and reducing your carbon footprint is a great idea.

Step 1: How Big Is Your Carbon Footprint?

Before you can reduce it, you need to know how big it is. The average person in the UK causes the emission of 13,000kg of carbon dioxide equivalent gases per year. The global average is 5,800kg, in India it’s around 1,300kg. There are various ways of measuring your carbon footprint. Usually they’re made up of a series of scores, such as Transport score, Energy score, Food score, and Waste score.

Step 2: Reduce Your Carbon Footprint

1. Turn down your thermostat. Turning your thermostat down by one degree centigrade could save a typical home £49 a year.
2. Close and/or line your curtains to keep in warmth. Setting your heating to turn off one hour before you leave the house and come on half an hour before you get home could save you £51 a year.
3. Turn off lights. Switching off four unnecessary lightbulbs and you could save £32 a year.
4. Turn off standby. Leaving your TV and all accessories attached to it on standby all the time could cost you £46 a year.
5. Turn down and use the half load setting on washing machines and tumble dryers. Washing laundry at 40 to 60 degrees centigrade in your washing machine could save you £12 a year.
6. Don’t boil more water in the kettle than you need to. If you always boil the amount of water needed for one cup rather than boiling a full kettle, you could save £30 a year.
7. Fix leaks as these are not only wasting water but also energy if they’re from a hot water source.
8. Use energy saving lightbulbs to save even more money and energy.
9. Recycle more!
10. Fly less. Train travel is up to 10 x more energy efficient than plane travel. Of course, not travelling at all is even more effective…

Step 3: Save Money and Feel Smug

SMART GRID

What is Smart Grid and why is it important?

Smart Grid refers to an improved electricity supply chain that runs from a major power plant all the way inside your home. In short, there are thousands of power plants throughout the United States that generate electricity using wind energy, nuclear energy, coal, hydro, natural gas, and a variety of other resources.These generating stations produce electricity at a certain electrical voltage.This voltage is then “stepped-up” (increased) to very high voltages, such as 500,000 volts, to increase the efficiency of power transmission over long distances. Once this electrical power gets near your town or city, the electrical voltage is “stepped-down” (decreased) in a utility substation to a lower voltage for distribution around your town or city. As this electrical power gets closer to your home, it is stepped-down by another transformer to the voltage you use in your home. This power enters your home through your electrical meter. The voltage in your home is typically 110-120 volts for most appliances, but may also be 220-240 volts for an electric range, clothes dryer, or air conditioner.

In many areas of the United States, the electricity delivery system described above is getting old and worn out. In addition, population growth in some areas has caused the entire transmission system to be over used and fragile. At the same time, you have probably added more electronic devices to your home, such as computers, high-definition TV’s, microwave ovens, wireless telephones, and even electronic controls on refrigerators, ovens, and dishwashers. These new appliances are more sensitive to variations in electric voltage than old appliances, motors, and incandescent light bulbs. Unfortunately, the entire electrical grid is becoming more fragile at the same time the appliances in your home are getting more sensitive to electrical variations. In short, the reliability of electrical power in the United States will decline unless we do something about it now.

Adding new transmission lines will help the utilities get more power from the power plants to your home. However, many communities don’t want new power lines in their areas. In addition, adding new capacity, although needed, will not increase the reliability of all the old electrical equipment reaching the end of its useful life. What is needed is a new approach that significantly increases the efficiency of the entire electrical delivery system. This approach will not only increase reliability, but  will also reduce energy in the delivery process and thereby reduce greenhouse house emissions. We call this new approach Smart Grid.

The basic concept of Smart Grid is to add monitoring, analysis, control, and communication capabilities to the national electrical delivery system to maximize the throughput of the system while reducing the energy consumption. The Smart Grid will allow utilities to move electricity around the system as efficiency and economically as possible. It will also allow the homeowner and business to useelectricity as economically as possible. You may want to keep your house set at 75 degrees F in the summer time when prices are low, but you may be willing to increase your thermostat to 78 degrees F if prices are high. Similarly, you may want to dry your clothes for 5 cents per kilowatt-hour at 9:00 pm in stead of 15 cents per kilowatt-hour at 2:00 pm in the afternoon. You will have the choice and flexibility to manage your electrical use while minimizing your costs.

Smart Grid builds on many of the technologies already used by electric utilities but adds communication and control capabilities that will optimize the operation of the entire electrical grid. Smart Grid is also positioned to take advantage of new technologies, such as plug-in hybrid electric vehicles, various forms of distributed generation, solar energy, smart metering, lighting management systems, distribution automation, and many more.
