The power ministry is considering making the default temperature setting for air conditioners at 24 degrees Celsius. Power Minister R K Singh, during a meeting on Friday, said the mandate will benefit consumers, both from a health and financial point of view. The ministry also wants AC manufacturers to add a label on the product indicating the optimum temperature setting for consumers. If the move is approved, it is likely to come into effect in a few months.
The ministry’s suggestion comes based on recommendations in a study conducted by the Bureau of Energy Efficiency (BEE). Its report suggests temperature settings to be in the range of 24 to 26 degree Celsius.
So, what is the reason behind this decision?
According to the ministry, the higher the temperature of the air conditioner, the lesser electricity consumed. This translates to saving at least six per cent of electricity consumed with an increase of just one degree in temperature. Singh explained, “Every one-degree increase in the air-conditioner temperature setting results in saving of 6 per cent of electricity consumed.”
Further, the minister said it is both uncomfortable and unhealthy to be in colder temperatures. “The normal human body temperature is approximately 36-37 degrees Celsius, but a large number of commercial establishments maintain a temperature around 18-21 degrees Celsius. This is not only uncomfortable but is actually unhealthy,” Singh said. He pointed out that wearing warm clothing or using blankets in a colder temperature is a waste of energy.
Singh’s campaign, which promotes energy efficiency, is likely to result in substantial energy savings and reduce greenhouse gas emission.
How will this help India’s power consumption?
According to BEE, only six per cent of households in the country use air conditioners. If all consumers adopt a default temperature setting, India could save 20 billion units of electricity annually.
The report states that the current estimate total installed air conditioner capacity is 80 million TR (tonne of refrigerator), which is likely to increase to nearly 250 million TR by 2030. Taking into account the huge demand, India can save around 40 million units of electricity usage per day.
