Each
time someone uses an air-conditioner, switches on lights, watches TV, leaves
the fridge door open or charges their mobile phone, greenhouse gases (GHG) are
released into the atmosphere.
These
modern day appliances, which are indispensable in our daily lives, are run by
electricity, but generating electricity has its downside since it contributes
to GHG, which is blamed for the global warming phenomenon.
For
any country there are almost four main sources of energy as natural gas, crude
oil, coal and coke, and hydropower. Electric consumption has increased
tremendously in almost every developing and underdeveloped country from 1990 to
2009, as the countries witnessed heavy industrial growth.
ENERGY
GUZZLING APPLIANCES
Cooling devices
such as air conditioners, refrigerators and chillers consume more energy
compared to all other electrical appliances. Nearly 67 percent of average
household electricity consumption is for these cooling appliances.
This is then
followed by appliances used for heating (11 per cent), lighting (seven per
cent), cooking (five per cent), entertainment (four per cent), washing machines
(two per cent) and others (four per cent).
When measuring
buildings, an audit found that air conditioners consume 62 per cent of total
energy, followed by power point-based appliances (20 per cent), and finally by
lighting (18 per cent).
USERS
BY SECTOR
It is important
for users from commercial and residential group to understand their own
electricity consumption trends and learn effective measures to reduce
consumption.
It will be good
for them and the environment. By doing their part to reduce energy usage, it
reduces CHG emissions and helps to save our depleting natural resources.
KNOW
HOW MUCH YOU EMIT
Energy saving
awareness is still low in most of the countries. Many are unaware that their
indifference to prudent energy consumption is detrimental to the environment.
Every, one
kilowatt hour (kWh) used releases 0.684 kg of carbon dioxide (CO2) emission,
the gas that contributes to the green house effect.
One can measure
his or her own CO2 pollution by multiplying monthly (electric) usage stated on
the bill with 0.684. The result of this represents the amount of CO2 released
in the air.
On average, if per
household electricity consumption is 251 kWh per month. This means one
household releases 171.68 kg of CO2 per month.
If everyone
plays their role by taking steps to ensure that they are using the least amount
of energy possible, it will make a big difference.
MANAGING
AIR CONDITIONERS
Many approaches
can be taken to reduce electric consumption. Using cooling appliances such as
air conditioners requires proper discipline, continuous maintenance and only a
small adjustment to daily routines.
Switch it off
when you leave the room, keeps the thermostat at a comfortable setting, rather
than an extreme cold setting, and clean the air filters regularly.
All windows and
doors should be closed to allow efficient air-conditioning, as leaks can add an
extra load to the system.
Wearing
appropriate clothing, too, can also help to expand one’s comfort zone while
reducing energy used for air-conditioning. For instance, a person wearing thick
clothes will need cooler temperatures to feel comfortable, compared to wearing
thinner clothes.
Believe it or
not, just by raising the temperature setting by one degree, you can save up to
6 percent on energy.
Besides the
above, using low 'emissivity' windows or by tinting windows and installing roof
insulation, solar heat intake can be reduced, thus allowing the cooling process
to take place more efficiently.
REFRIGERATOR
CARE
As for
refrigerators, this appliance needs good ventilation. Leaving a decent space
between the refrigerator and the surrounding wall or cabinets helps provide
good airflow. Today, many place their refrigerator in a tight slot between
their kitchen cabinets. This might look nice, but it is bad for the environment
as it promotes energy waste.
Poor ventilation
means a refrigerator has to work extra hard to keep cool. Do not keep the door
open for long periods and make sure the door seals are always in an airtight
condition.
What
Next…?
Now
you can calculate how much is your own contribution in devastating the nature
and environment and can take some proactive steps to ameliorate the same. Next time
think at least once while you leave your fan, TV, PC, Laptops, AC or any
appliances or gadgets running, for hours. This could be a gentle and intuitive care
for nature and planet’s environment.
Make
us aware of what is your view over usage and after effect of these modern days’
accessories and gadgets. How precisely you use these appliances to minimize
your GHG emission.
