Minimise

Why Minimise

There are so many stories we can tell ourselves to justify doing nothing about the impending climatic catastrophe, but perhaps the most insidious is that, whatever we do, will be too little too late.  That it will take the Government and the Big Corporate to make any difference.

Climate change has arrived well ahead of schedule. Scientists’ projections that seemed dire a decade ago turn out to have been unduly optimistic: the warming and the melting, and the positive feedback loop connecting them, is occurring much faster than the models predicted.  It is true that laws and money is necessary.  And yet, laws and money cannot do enough either.   It will also take profound changes in the way we live.  Because at the bottom of the climate-change crisis is another crisis - that of our lifestyles. The Big Problem is nothing more or less than the sum total of countless little everyday choices, most of them made by us consumers, and most of the rest made in the name of our needs, desires and preferences.

Striving to live in harmony with Nature is not a new endeavour. In the past, the reasons for doing so have been different – like the Gandhian values of inculcating self-sufficiency.  However, since the time of Adam Smith, we have moved inexorably towards “division of labour”.  Unfortunately, this move towards specializaton has also proved to be a move away from personal responsibility. We have abdicated responsibility for everything except the very narrow range of products/ services whose “producers” we are.  The rest of the time, we are just “consumers”. Virtually all of our needs and desires we delegate to specialists of one kind or another — our meals to agribusiness, health to the doctor, education to the teacher, entertainment to the media, care for the environment to the environmentalist, political action to the politician.

This division of labor has given us many of the blessings of civilization Yet this same division of labor obscures the lines of connection — and responsibility — linking our everyday acts to their real-world consequences, making it easy for us to overlook the coal-fired power plant that lights our computer screen, or the mountaintop that had to be destroyed to provide the coal to that plant, or the streams running crimson with heavy metals as a result.  Specialists ourselves, we can no longer imagine anyone but an expert, or anything but a new technology or law, solving our problems. As the closing credits roll out at the end of “An Inconvenient Truth”, Al Gore asks of us only that we change our light bulbs, because he probably can’t imagine us doing anything much more challenging, like, say, growing some portion of our own food.

The reasons not to act are many and compelling.  But here are a few reasons that we might put on the other side of the scale:

If we do act, we will set an example for other people. If enough other people act, each one influencing yet another in a chain reaction of behavioral change, markets for all manner of green products and alternative technologies will prosper and expand. (Just look at the market for hybrid cars.) Consciousness will be raised, perhaps even changed: new moral imperatives and new taboos might take root in the culture. Driving a gas-guzzler or setting the at AC at 15C might come to be regarded as outrages to human conscience. Not having things might become cooler than having them. And those who did change the way they live would acquire the moral standing to demand changes in behavior from others — from other people, other corporations, even other countries.

How do you know you have it right!

Deciding to take responsibility for one’s consumption choices is only the first step in minimizing our carbon footprint.  While the implications of some choices are fairly well evaluated – like using less electrical power from the grid; for others, the information is, at best, incomplete, and at worst, misleading and confusing!

What to buy!

The past few years have seen an explosion of green marketing.  While this has made available to the consumer more choices, consumers may find themselves perplexed by how to gauge the environmental impact of the many products that claim to be eco-friendly. For one, as of now, it is very difficult to evaluate the claims of products that say they are biodegradable, carbon neutral or made from sustainable materials. Even if one were to take the green-claims of the various manufacturers at face value, there are still many processes whose Carbon footprint implications cannot be clearly evaluated. Is eating local or walking to work really going to reduce my carbon footprint? According to one analysis, if walking to work increases your appetite and you consume more meat or milk as a result, walking might actually emit more carbon than driving.

Perfect knowledge, that takes into account the sourcing of the raw materials, the manufacturing process, the transportation involved, and the final disposal, is many years away.  The best we can do for now, is to make informed choice with the limited information we have and to realize that instead of buying three pairs of organic cotton jeans, it is better to buy just one pair, and even better to make do with our existing pair of ordinary jeans

How much to buy!

Conspicuous consumption is a significant part of the Global Warming problem. Therefore, it doesn’t require too much intelligence to hypothesize thus: it is a misconception that by buying anything, whether Green or not, we are solving the problem.

Environmentalists say some products marketed as green may pump more carbon into the atmosphere than choosing something more modest, or simply nothing at all.  Coming back to an earlier point - instead of buying three pairs of organic cotton jeans, it is better to buy just one pair, and even better to make do with our existing pair of ordinary jeans

This section of NO2CO2 will try to present and evaluate “Minimizing” options.  We strive to stay up to date with current technological developments, be as fair as possible while evaluating different options and state up-front if any issues are unresolved.  Any errors of judgments or facts is completely unintentional and we will be very happy to be corrected.

CFL (Compact Fluorescent Light) Bulbs

General Description

A Regular 60 Watt Light Bulb (Incandescent Bulb) can be replaced by an 11 Watt (+ 3 Watt Choke) CFL Bulb, without any compromise on lighting power. This translates to a 75% energy saving. While CFL bulbs have been a technology causing some concern due to their mercury content, recent innovation have lead to the creation of Eco-Friendly ‘Green’ CFL’s which have a significantly reduced mercury content. An example of these eco-friendly Green CFL’s, are those manufactured in India by Havells India Ltd.

Additionally, since these bulbs last approximately 6 times longer than (5 years at 3.3 hours per day usage) regular bulbs, their higher initial cost is recovered through fewer regular bulb purchases which burnout approximately every 10 months (at 3.3 hours per day usage).

And this is the least known, but very crucial, advantage of CFL and other energy saving lighting technologies – they reduce the heat load that air conditioners must ‘fight’. This is because more than 98% of the energy output of an Incandescent Bulb is wasted as heat energy, which warms the air in a room. By reducing the power supplied by 75% (by using CFL bulbs), the quantity of heat generated in the room is also reduced proportionally. The end result is a significant savings in energy costs and carbon footprint from Air Conditioner use.

Footprint Savings

Replacing 6, 60 Watt Light Bulbs with 11 Watt CFL’s, used 8 hours per day, can reduce carbon footprint by 1.2 tonnes CO2e annually and save you at least Rs. 3400 per year on your electric bill (based on all-India average electricity rates). 

Cost Savings

Replacing 6, 60 Watt Light Bulbs with 11 Watt CFL’s, used 8 hours per day, can save you at least Rs. 3400 per year on your electric bill (based on all-India average electricity rates).

Motion Detectors (PIR Sensors)

General Description

There are many spaces in household and residential building interiors that do not require continual lighting and cooling because people are just passing through such spaces (a good example is stairwell and compound lighting in buildings and fan/light operation in toilets and elevators in commercial and residential premises)  the energy wasted in keeping such spaces continually lit/ temperature regulated, can be virtually eliminated by use of relatively inexpensive motion-detectors (Passive Infrared Sensors- PIR Sensors), that automatically switch-off fans, lights and any other devices that are not required to operate once all persons have vacated a certain space. The low cost of these devices equates to payback periods (i.e. the time span over which the cost of energy conserved equals the purchase cost of the implement) in the range of a few months.

Solar Heat-Reflecting Clear Window Films

General Description

Most of the carbon footprint from air-conditioned residences and offices is the consequence of electricity consumption by cooling appliances. While installing more energy efficient air conditioners is an effective way to reduce this footprint, the footprint reduction can be greatly enhanced by reducing the quantity of incoming heat energy that the device has to ‘fight’.
The commonly used dark-tinted films applied on automobile windows, is an example of a relatively outmoded method of reducing incoming heat energy to Minimise air-conditioning load. Reflective ‘mirror-like’ surfaces that reject solar energy also perform the same function. These solutions, while reducing heat load, do however have an adverse effect on the lighting requirements of the indoor areas they shield – they block visible light as much as they block heat energy from the sun. Recent innovations have resulted in the creation of films that reject upwards of 90% of infrared and UV rays (the primary agents of conveying solar heat into interiors of building) while permitting 70% of visible light to pass through. Such films are known as spectrally selective films. By comparison, heavy silver window films permit just 15 to 20% of visible light to pass through. As an added benefit, the UV-blocking property of these films leads to dramatic reduction in fading of upholstery, carpets and other soft-furnishing. Prolonging the life of these resource intensive and high cost products has notable indirect but tangible footprint benefits as well.
The lower cost of incorporating this solution relative to the cost of replacing existing cooling devices elevates this alternative in the priority list of interventions; it ought to be implemented as a pre-requisite prior to any other capital intensive solutions.

Footprint Savings
Placing a solar reflective window film (Spectrally selective films) onto on a window we can save carbon footprint by 10.2 kg CO2e per year per Square foot of a window film.

General Description

CFL Bulbs represent the most popular energy saving lighting device used to dramatically cut carbon footprint. They belong to new age technology. But there is a technology, fast approaching and no longer just on the horizon, called Light Emitting Diode (LED) lighting that provides even greater energy savings compared to CFL Bulbs. An LED Bulb consuming merely 6 Watts of power can emit the same light as a 11 Watt (+3 Watt Choke) CFL Bulb or a 60 Watt Regular Incandescent Bulb.Additionally, since these bulbs last approximately 40 times longer than regular bulbs and 6 times longer than CFL bulbs, their higher initial cost is recovered through fewer bulb purchases.And this is the least known, but very crucial, advantage of LED and other energy saving lighting technologies – they reduce the heat load that air conditioners must ‘fight’.

Ducted Air coolers

General Description

Evaporative coolers are useful in low-humidity areas or regions. The outdoor air will pass over water saturated pads and cause the water to evaporate into it. The 15 to 45 degree F (depends upon humidity) cooler air is then directed into the space to be cooled and pushes warmer air out through windows that are opened. Evaporative coolers cost about one-half as much to install as air conditioners and use about one-quarter as much energy. The windows can be opened in this type of air cooling system so it keeps fresh air always inside the space to be cooled. The evaporative air cooler can be installed in two ways: Central-location installation for small spaces and ducted system for larger spaces. This cooling system can be installed for domestic, commercial and industrial spaces.

Wind energy based systems are now readily available in appropriate sizes for installation on building rooftops and other residential household use. It represents a well-established and proven technology for harnessing nature’s renewable energy resources which has undergone a technological renaissance in recent years that have made such systems financially feasible for small scale applications. As wind energy systems (i.e. a windmill plus the energy storage devices such as invertors etc) harness energy from wind speed, they are ideal power generating solutions for non-sunny days when solar power generation potential is low. In combination with solar systems (called wind-solar systems) they are perfectly capable of providing a stable supply of power ranging from 500 Watts to 2.5 kW. With this amount of power, a residential building could easily operate staircase and compound lights as well as support a portion of the power needs of each dwelling unit for operating some fans and lights.

Solar Panel Lighting

General Description

Since solar energy is only available during the daytime, electricity generated is stored in a battery and made available to devices wired to it using an ‘Inverter’ that converts stored energy to an Alternating Current. Solar systems require the appliances to be run on it to be wired independently of the other circuits in the house (unless one desires to run all electricity consuming appliances to run on solar power – a possible but prohibitively expensive solution). Solar panel systems are ideal for powering lights and fans. By first minimizing the total power load (replacing conventional and CFL Bulbs with LED Lighting and replacing conventional fans with energy saving fans) the size of the required Solar panel can be reduced. This leads to maximum economy as the replacements costs less than the increased cost of a larger Solar panel. Further economy can be achieved by converting the wiring of the Solar-power run devices to Direct Current (DC) Wiring from the conventional Alternating Current (AC) wiring. This lowers the cost of the system as an ‘Inverter’ is no longer required and improves the efficiency of the system since the loss of power incurred due to the ‘Inverter’ is avoided.

Solar Lantern

General Description

Solar energy can be converted directly to electricity. Conventionally, this is accomplished through Solar Photo Voltaic (PV) Panels. These are the rigid, rectangular shaped panels that are visible mounted on top of street-lights and traffic lights in some cities. Solar panels are available for residential installations through a multitude of manufacturers and distributors in India. Combined with a wind energy system, they for a complimentary set of a renewable source of reliable power supply – during sunny periods the solar panels would generate a bulk of the power while the wind system would provide power during cloudy and windy periods.
Besides wired systems for household appliances, most of the above manufacturers and distributors also provide stand-alone solar lanterns and lamps that can provide light for 4 to 5 hours after sundown. These can be used to substitute existing lamps and lights resulting in reduced carbon footprint along with electricity cost savings.

Recently, big strides in solar panel manufacturing technology have precipitated a new generation of solar panels that are essentially like ‘plastic’ sheets which are flexible and can easily be applied over many different kinds of surfaces such as roofs, doors, outer walls of buildings etc. The technical term for them is Photovoltaic Laminates (PVL) or Thin-Film Solar Modules. The flexible nature of these panels addresses the greatest limitations of the existing crystalline solar panels – fragility, portability, and manufacturing costs. This technology is currently available only through a select few manufacturers. They are expected to dramatically alter the economics of solar power – making it significantly more affordable and closer to being cost-competitive compared to conventional sources of power than its predecessor.

Solar Air Conditioning

General Description

The most common technique consists in using solar collectors to provide the heat that is directed toward an absorption chiller. This machine dissociates, by boiling point, a solution of water and bromide of lithium. After cooling, the recombination of the two components produces the cold air which is distributed then into the zones like classic air-conditioning. The sun can provide a substantial part of the energy needed for air-conditioning. It can be used, either as stand-alone systems or with conventional air conditioning, to improve the indoor air –quality of all types of buildings. The main goal is to utilize “zero emission” technologies to reduce energy consumption and CO2 emissions.

Air Conditioners

General Description

1.Reduced AC Use
One night (8-hours) of air-conditioner use (1-ton AC suitable for a small sized room) results in approximately the same ‘Carbon Footprint’ as from driving an average Indian car for 85 kilometers. Reducing the use of these high-energy consuming appliances is indisputably the most effective means of reducing your footprint – even better than replacement with better technology
2. An AC uses 3 to 5 percent less energy for each degree set above 22°C (71.5°F); Setting the thermostat of your room air conditioner at 25°C (77°F) will therefore result in 10 to 15% energy and footprint savings without compromising comfort too much.
3. Using ceiling or room fans along with the AC allows you to set the thermostat higher because the air movement will cool the room.
4. Clean the air-conditioner filter every month. A dirty air filter reduces airflow and may damage the unit. Clean filters enable the unit to cool down quickly and use less energy.
5. Minimise use of the "outside air" option. Energy consumption for cooling the incoming outdoor air is significantly greater than energy required to re-circulate the already cooled indoor air.
6. A very important step: figuring out the right size as per the need. Oversized air conditioners cycle on and off more frequently. Also, they don't dehumidify as much, reducing comfort levels and causing users to set thermostat temperatures even lower. Result: higher electricity bills and larger footprint.

7. Incorporate an electronic timer switch and digital thermostat in old air conditioners to monitor and control the fan speed.                                        

8. Do not place any heating equipment like light,TV, Room Heater near to air conditioner thermostat.                

9. Place the air conditioner outside unit in a shade or below a tree shade. This helps to consume 10% less energy.

Refrigerators

General Description

1. Make sure that refrigerator is kept away from all sources of heat, including direct sunlight, radiators and appliances such as the oven, and cooking range.
2. When it's dark, place a lit flashlight inside the refrigerator and close the door. If light around the door is seen, the seals need to be replaced. Alternatively, use the following test: With the door open, place a paper so that half of it protrudes outside the frame. Then close the door. The paper should be held snugly. If paper slips out easily, replace the door seals.
3. Place the refrigerator so that there is sufficient space for continuous airflow around the refrigerator. Refrigerator motors and compressors generate heat, if the heat can't escape, the refrigerator's cooling system will work harder and use more energy.
4. Allow hot and warm foods to cool and cover them well before putting them in refrigerator; the Refrigerator will use less energy and condensation will be reduced.
5. When dust builds up on refrigerator's condenser coils, the motor works harder and uses more electricity. Clean the coils regularly to make sure that air can circulate freely.

6. For Manual Defrost (Direct Cool) Refrigerators, accumulation of ice reduces the cooling power by acting as unwanted insulation. Defrost freezer compartment regularly for a manual defrost refrigerator

7. Don't keep your refrigerator or freezer too cold      

8. Do not open and close the doors often                                                                                               

9. Set temperatures at optimal level. For food compartment set between 36 degree and 40 degree F. And for freezer set between zero degree and 5 degree F.

Computers & Printers

General Description

1. While purchasing a printer, select one with power management capabilities. Printers with automatic "power down" features can reduce electricity use by over 65% whilst idle.
2. Consider buying a laptop for your next computer upgrade. Laptops use upto 90% less energy compared to desktop computers
3. Screen-savers cause your computers systems to keep running unnecessarily and are a waste of energy. Instead, set computers, monitors, and copiers to use sleep-mode when not in use - this helps cut energy cost and footprint by approximately 40%.
4.If your computer must be left on, turn off the monitor; this device alone uses more than half the system's energy. Consider this: you can laser print 800 pages with the energy wasted by leaving a computer monitor ON overnight.
5.It is a popular misconception that keeping computers ‘ON’, even when not in use, reduces system wear due to power-on and off operations.

6.  Upgrading to the latest MFD (Multi-Function-Device) and getting rid of separate scan, fax, scanner, printer, copier machines saves over 20-40 kg of CO2e per week.

7.    Refill Ink cartridges instead of buying new ones.

8.     Reduce margin settings for the documents and print in draft mode

9.Use batch copying for photocopying and saving all your photocopying for the day for a particular time.

Wrong. Start-ups and shutdowns do not use any extra energy, nor are they hard on your computer components. In fact, shutting computers down when you are finished using them actually reduces system wear - and saves energy. A computer that runs 24 hours a day, for instance, uses more power than an energy-efficient Refrigerator.Turning on ‘Power Management Feature’ For a Windows® based PC – this can save up to 70% energy:
1. Press ‘Start’
2. Go to ‘Control Panel’
3. Select ‘Power Options’ or ‘Power Management Options’
4. Set Monitor turn off time (15 mins recommended) System stand-by time (30 mins recommended) and other setting depending on your system.

For Windows XP laptops:
choose ‘Portable/ laptop and change the options under “running on batteries”. For the ultimate battery life, for example, set “Turn off Monitor” to “After 2 Minutes” and “Turn off Hard Disk” to “After 5 Minutes”.

For Windows Vista laptops:
Vista uses pre-set options called “Power Plans”. The “Power Saver Plan” is a good start but you can also click “Change Plan Settings” and change “Turn off Display” to “2 minutes”.

For Apple Macs:

Click the apple icon at the top left, then choose “System Preferences”. In the “Hardware” section, click on “Energy Saver” icon change settings for both the “Power Adapter” and the “Battery” options by moving the slider under “put the computer to sleep when it is inactive for” and “put the display to sleep when the computer is inactive for” sliders.

Tips on making your laptop battery last long:

Despite improved battery technologies and more energy efficient processors, bigger brighter screens drain battery power, as do hard disks and DVD drives
1.Turn of wireless off when not in use – Wi-Fi connections drain power even when you are not connected to the internet. To turn the wireless off, look for a switch that turns the airport “OFF” on the side of your laptop. Alternately, there may be wireless icon on the task bar that you can (right)click on to bring up the instructions needed to enable or disable your wireless
2. Adjust the brightness of your screen- the brighter your computer screen, the more energy is needed to back-light it. Make the screen as dim as you comfortable can.
To do this – there may either be a function key command (eg Fn + 8), a single key command (eg F1, F2 on Mac), a physical control or buttons on the side of your computer to do this. Please check your computer’s manual if you are not sure.
3. Do one thing at a time – keeping several programs open simultaneously uses the computer’s processing power and also its virtual memory. Exit one program before switching to the next
4. Hibernate (For Windows laptops) – a Windows laptop has two standby modes – ‘Hibernate’ and ‘Suspend’. ‘Suspend’ restarts faster but uses more power. To switch to Hibernate in Windows XP, go to “Power Options” in control panel and click ‘’Hibernate’ tab, then tick ‘Enable Hibernation’. Click “OK” to finish
5. Unplug USB devices – unplug any USB or PC card network adapters, memory keys that you are not using
6. Eject CDs and DVDs if not using them – even if your computer is not using the CDs or DVDs in its drive, it checks them sporadically which wastes energy
7. Close non-essential start-up programs – you might be surprised at how many programs launch on your computer the moment you boot up. While some of them show up on your screen, others run silently in the background. All such programs use energy, irrespective of whether you use them. If you are not sure what a particular start-up program does, do a search on it before disabling it.

Disabling start-up programs on Windows:


Click on the “Start” button and then “Program”. Find the “Startup” folder and open it. If you see anything you do not need, fight click and select “Delete”.
Disabling start-up programs on Apple Mac:
Click on the Apple logo. Select “System Preferences”. Click on the “Accounts” tab under “System” group. Click on click on “Login Items”. Delete any start-ups that you do not need.
8. Quit non-essential services – desktop search applications, network tools and messaging application run in the background even when you are not using them. You can (right) click on their icons and select the relevant ‘Exit’ or “Switch Off’ option.

9. Energy consumption can be reduced by stopping screensavers.

10. Use laptops as they are more efficient than desktops.

11. Use a small size monitors. A 17 inch monitor uses 40% more energy than a 15 inch monitor.

Cut Standby Power

General Description

“Standby Power is electrical power that a device consumes when not in present use, but plugged in to a source of power and ready to be used”.  In other words, “Standby Power” is the power consumed by appliances when they are turned off using a remote control and not from the ‘Plug Point Switch’.

This ‘invisible’ power consumption perhaps seems trivial but recent studies by the International Energy Agency (IEA) have established that an average household usually consumes up to 50 units of electricity (kWh) per month just due to appliances kept on ‘Standby Mode’. An average 2-bedroom home for a family of 4 in India can consume approximately 300 to 400 units of electricity per month. The seemingly trivial ‘Standby Power’ would then be responsible for 12 to 14% of the footprint from electricity consumption!

In short, one of the easiest ways to immediately reduce your carbon footprint is by learning to turn off the appliances from ‘Plug Point Switch’. Cut the Standby power!

Natural Lighting

Description


Natural lighting through dormer windows, skylights, and transparent cement as well as optimal positioning of windows can reduce the lighting load incorporated into building design. This intervention has the twin beneficial impact of reducing manufacturing related LCA impacts of lighting fixtures as well as reduced energy consumption. Some green architecture guidelines specify design lighting loads in the vicinity of 7.5 W/sq.m. For building occupancy of 10 hours/day, the average annual electricity conservation and GHG emissions mitigation per sq. m of naturally lit space relative to conventionally lit space is estimated 27 kWh/sq.m and 24 kgCO2e/sq. m.

Natural Ventilation

Description


Natural ventilation through facilitation of wind draft through open walls and from under floor spaces, channelling through hollow support pillars and stairwells were some of the ways in which natural ventilation can employ. As in the case with natural lighting, natural ventilation has the twin beneficial impact of reducing manufacturing related LCA impacts of HVAC systems (by either eliminating it in some spaces or reducing the design capacity) as well as reduced energy consumption. The primary savings from natural ventilation systems are the consequence of reduced power consumption for air handling unit fans.
