Energy consumption in Iran has high rate due to its geographical location as well as high industrial and residential energy consumption. Drought and the impossibility of using some hydroelectric power plants, global warming and extravagant electricity consumption, as well as novel technologies (e.g., cryptocurrency mining) are the reasons to cause the increment of electricity consumption. The main reason for national power outages is the instability of energy production and consumption balance. Such events disturb the balance between the production and consumption of electricity. The utilization of renewable energies is one of the primary solutions to eliminate the gap between energy production and consumption. Taking into consideration the current conditions and the 20-year forecast of energy consumption and production in Iran, a vast gap can be observed between these two cases. In this paper, by considering two different scenarios using renewable energy, this gap is addressed, causing the amount of power production to exceed the amount of consumption in the long term.

Nowadays, increasing energy efficiency is the economical and fastest way to generate electricity in the world. Therefore, the importance of energy saving has been considered for many years in Iran, but the allocation of subsidies to energy production sector has led to the lack of a logical and specific solution to reduce energy consumption and is still one of the main challenges in Iran's economy since paying insufficient attention to energy saving in all applications. Due to the climate of Iran, the use of evaporative coolers for cooling and air conditioning is very common in summer, but installed electromotors in these coolers are one of the high-consumption equipment in peak hours which the upgrade of them can have a significant impact on reducing the peak of energy consumption in the country. From this point of view, Brushless DC (BLDC) motors, as high-efficiency electromotor type, have been investigated for evaporative cooler application.In this paper, the technology development procedure of these BLDC motors for evaporative coolers in the country is presented and at the end, the results of production of this type of electromotors by seven domestic companies and their operation these coolers are presented.
