Campaign to promote energy efficiency in the area of air-conditioning

• Minister of Power and New & Renewable launched a campaign to promote energy efficiency in the area of air-conditioning.
• Under the guidance of Ministry of Power, the Bureau of Energy Efficiency (BEE) has carried out a study and has recommended that the default setting in the air-conditioning should be at 24 degree Celsius.
• The new campaign will result in substantial energy savings and also reduce greenhouse gas emission.
• This initiative is launched on voluntary basis to increase awareness and encourage consumers to adopt the guidelines.

Analysis:

• Every one degree increase in the air-conditioner temperature setting results in saving of 6 per cent of electricity consumed. Normal human body temperature is approximately 36-37 degree Celsius, but large number of commercial establishments, hotels and offices maintain 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. Some countries like Japan have put in place regulation to keep the temperature at 28 degree Celsius.
• Considering the current market trend, total connected load in India due to air conditioning will be 200 GW by 2030 and this may further increase as today only about 6 per cent of households are using air conditioners. As per our current estimate total installed air conditioner capacity is 80 million TR (ton of refrigerator) in the country, which will increase to about 250 million TR by 2030. Considering this huge demand, we can save about 40 million units of electricity usage every day.
