The Wordl faces a looming  » cold crunch »

” Using air conditioners and electric fans to stay cool accounts for nearly 20% of the total electricity used in buildings around the world today. And this trend is set to grow as the world’s economic and demographic growth becomes more focused in hotter countries. As incomes and standards of living increase, more people will naturally want to buy and use air conditioners to keep cool. Wider access to cooling is necessary, bringing benefits to human development, health, well-being and economic productivity. But it will have a significant impact on countries’ overall energy demand, putting pressure on electricity grids and driving up local and global emissions.
The growth in global demand for space cooling is such a blind spot: it is one of the most critical yet often overlooked energy issues of our time. If left unchecked, energy demand from air conditioners will more than triple by 2050, equal to China’s electricity demand today.
The answer lies first and foremost in improving the energy of air conditioners, which can quickly slow down the growth in cooling-related electricity demand. Policy interventions can address this and will have a significant and rapid global impact.
In the longer term, the underlying need for cooling can also be greatly reduced by better building design and tougher building codes, as well as by increased rates of energy efficiency improvements in existing buildings.
This is particularly important today, given the slowdown we’ve seen in global energy efficiency improvements. Simply put, governments need to do more on efficiency, which is one of the key tools to reach long-term climate goals and also reduce energy-related air pollution.
Determined policy action is critical to ensure a sustainable path to the future of cooling and allow people to reap the benefits of cooling without straining energy systems or the environment.
I hope that  will help to raise awareness globally about one of the most critical energy issues of our time and that it will provide an important source of guidance for policy makers in particular who are working towards a more sustainable global energy system. (IEA source)
