AIRCONDITIONERS AND THEIR ENVIRONMENTAL IMPACT

These days we have been pondering about the carbon footprint, the lack of recycle stations, cheap veges and meat (which meant non organic or Non-hormone/ antibiotics free.. as these would be more expensive) here in Singapore.
What about the impact of Airconditioners on our environment? Besides, we have only 1 planet that we can live in (for now). We should be aware of the damages we are causing it and try to reverse them.. or heal the world before it is too late..

Environmental Impact
Energy Use
The electricity generated to power air conditioning carries both global and personal health consequences. In burning fossil fuels such as coal to supply electricity to homes and workplaces, power plants discharge clouds of soot and other pollutants into the atmosphere. Among these are mercury and carbon dioxide (CO2). Air conditioner use in the U.S. results in an average of about 100 million tons of CO2 emissions from power plants every year.
HCFCs
Formerly used as cooling agents, ozone-depleting chlorofluorocarbons (CFCs) have been replaced by hydrochlorofluorocarbons (HCFCs), which deplete 95 percent less ozone. However, booming demand for air conditioners in hot climates such as India and China has upped the chemical’s output in developing countries 20 to 35 percent each year, causing damage at an alarming rate and possibly setting back ozone recovery by 25 years. In industrial countries, HCFCs are being replaced with ozone-safe cooling agents and would be banned in the U.S. by 2010. But HCFCs will be allowed in developing countries through 2040, and because they’re still cheaper to use than ozone-safe chemicals, production in developing countries is expected to increase fivefold by 2010.
Disposal
Federal law requires that HCFCs be recovered from air conditioners and other appliances before they are dismantled for recycling or tossed in landfills, and the EPA is authorized to impose fines of up to $25,000 for failure to comply with regulations. Before discarding your old unit, search for a company that is EPA-certified to recover HCFCs. Share the Air has certified companies listed by region.
Personal Health
In the midst of sweltering heat waves, air conditioning can be a lifesaver, protecting against heat stroke and hyperthermia. But, without proper maintenance, air conditioners can also be a health hazardDirty filters can allow allergens, pesticides and other particulate matter to enter your home from the outside, posing threats to indoor air quality. Exposure to those pollutants can trigger a host of health problems, including allergies and asthma and eye, nose and throat irritation.
Not only we should get a good airconditioner that is with the latest green technology, maintaining it is critical for users as well!
Now, when was the last time your airconditioners had a good cleaning?
Cheers!
