As a result of global warming and the new needs for comfort, have triggered the race for air conditioners, elements now unmissable in the hot summers. The estimated global growth rate is one sale every ten seconds by 2050, to reach 5.6 billion worldwide.

These data are released by the International Energy Agency (IEA) and paint a terrible scenario for the environment, considering the huge amount of energy used by air conditioners.

By 2050 three Asian countries will count more than half of the global air conditioners: China, India, Indonesia. The increase of population and the general improvement of the economic conditions, the peak of electric load, it is estimated, will go up from the current 10% to 45%.

As a subsequence, there will be higher need for electricity, resulting in investment in the construction of power plants and greater energy use. Such growth could lead to a “cold crunch“, a cold crisis, in the absence of real policies of energy efficiency. Already today we are witnessing blackouts and forced interruptions of public lighting, and, in the coming years, these phenomena could be more and more widespread and lasting.

The highest peak will be during the night, therefore, it will be difficult to compensate the need with the photovoltaic energy. The alternating current will then be the primary source of energy, with consequent environmental risk.

In order to reduce energy demand, it is fundamental to work on the energy efficient air conditioners. A more efficient air conditioner would imply considerable benefits, saving about $2.9 trillion in operating costs, infrastructure and non-renewable energy.
