Abstract: In this work, we estimate the replacement cost of traditional light sources by light-emitting diodes (LEDs) in Pakistan, India, and Bangladesh. From the Year 2021 to Year 2027, if all traditional light sources are replaced by LEDs, in these countries, the energy consumption due to LEDs in Pakistan, India, and Bangladesh will be 6 TWh, 47 TWh, and 5 TWh. The estimated average energy consumption of other light sources in Pakistan, India, and Bangladesh are 18 TWh, 153 TWh, and 15 TWh. Similarly, the estimated energy consumption cost of LEDs, during the stated period, in Pakistan, India, and Bangladesh is USD 0.6 billion, USD 4 billion, and USD 0.3 billion, respectively. The estimated average energy consumption cost of traditional light sources is USD 2 billion, USD 13 billion, and USD 1 billion in Pakistan, India, and Bangladesh, respectively. The estimated average energy saving, by using LEDs, in Pakistan, India, and Bangladesh is 12 TWh, 105 TWh, and 11 TWh respectively. By using LEDs instead of other traditional light sources, USD 1.2 billion, USD 9 billion, and USD 0.6 billion can be potentially saved in Pakistan, India, and Bangladesh, respectively.
