India’s share in global air conditioning units to jump from 2.2% to almost 25% by 2050

Increasing incomes and urbanization will see an increase in room air conditioning units from 1.2 billion to 4.5 billion in the world by 2050 when India alone may account for one billion units.

The refrigerants used for cooling are the major contributors to global warming, and if left unchecked, they could cause global temperatures to rise by 0.5 degrees Celsius. Under a business-as-usual growth trajectory, about 4.5 billion room air-conditioners are estimated to be installed by 2050 — a nearly four-fold jump from today’s installed base, with emerging economies observing a five-fold increase.

HFCs are a family of gases that are largely used in refrigerants at home and in-car air-conditioners. However, they substantially worsen global warming. India, China, the United States, and Europe have committed themselves to reduce the use of HFC by 85% by 2045.

In 2016, India was a signatory to a compact of 107 countries to “substantially phase” out a potent greenhouse gas, called hydrofluorocarbons (HFC), by 2045 and move to prevent a potential 0.5 C rise in global temperature by 2050.

Need for energy efficiency in the area of air- conditioning:

Every one-degree increase in the air-conditioner temperature setting results in saving of 6% of electricity consumed. The new campaign will result in substantial energy savings and also reduce greenhouse gas emission.

Besides, normal human body temperature is approximately 36-37 degree Celsius, but a large number of commercial establishments, hotels, and offices maintain the temperature around 18-21 degree Celsius. This is not only uncomfortable but is actually unhealthy.

Setting the temperature in the range of 18-21 degree Celsius compels people to wear warm clothing or use blankets; therefore, this is actually wastage of energy.

Efforts by the government in this regard:

Union Power Ministry has launched a campaign to promote energy efficiency in the area of air-conditioning. This initiative is launched on a voluntary basis to increase awareness and encourage consumers to adopt the guidelines. It will save energy and reduce greenhouse gases.
