Air conditioning is the world's second biggest hazard


By Chris Bryant

Most Americans have air conditioning but almost anyone in Germany does. At least not yet.

So, while Berlin's temperature was up to 37 cents (99 fahrenheit) this week – the record for June – I was uncomfortable to go to Bloomberg's office, where it is cool and artificially cool.

Letting people stay in excessive weather and focus on their work and sleep at night, air conditioning has played a major role in running global prosperity and happiness in the past few decades – and that revolution has not yet started. This is a modern tool in almost half of Chinese households, but only 88 million of 1.6 billion people living in India and Indonesia can get home conditioning at home, Bloomberg New Energy Finance recently reported in a report.

Relief for many people is found. Due to the combination of population growth, rising income, decreasing resources and urbanization, the number of internationally established air-conditioning units has increased from 1.6 billion in the middle to 5.6 billion in the middle of the century. Agency



Carbon dioxide emissions rose 2% in 2018, the fastest pace in seven years. Depending on what we know about the growing climate crisis, the increase was horrible in its own right. But the near reason was particularly difficult: due to heavy weather, there was more demand for air conditioning and heating in 2018, BP Plc explained in its annual review of the energy sector.

It is not difficult to imagine an evil cycle, in which more hot weather demands more demand for air conditioning and therefore demands even more power. It also gets more emissions and warm temperatures in turn.

That feedback loop also exists at the local level. Air conditioning heat out heat, the so-called "urban heat island" stimulates the effect, which heats the cities nationwide.

BNEF hopes that by 2050 the demand for electricity from residential and commercial air conditioning will increase by 140 percent – comparable increase to increase the overall electricity consumption of the European Union. Air conditioning will present 12.7% electricity demand in the middle of the century, which is about 9%.

Fortunately, this additional requirement will be met by solar power (the cooling requirement is highest during sunlight). But, when the sun goes down, the temperature does not always return to comfortable levels, there is fear that additional electricity will be provided by some fossil power.

Despite nearly a fifth of global energy consumption, the climate remains blind in the debate. Inefficiencies of air conditioning systems or poorly-constructed homes and offices are not as attractive as electric cars and people are ashamed to fly. At least in Germany's "Psevoice" movement, a way to build houses that requires very little heat or cooling, shows that some people are starting to recognize this risk.

There are also lessons learned from the light world. LED revolution was accelerated by renewal, but also by labeling good energy efficiency labeling and closure of advanced technology. Need to do something similar with air conditioning. A big step was made in January when the Kigali update was implemented in the Montreal Protocol. Although not known, their intent is to stop using powerful greenhouse gases called hydrofluorocarbons, which are widely used in air conditioning systems. Until the transfer is done, this alone can cause 0.4 ° C excess heat by the end of the century.

Still the correct form, the administration of President Donald Trump has not yet released Kigali in the Senate for support, however, American producers will benefit from the demands of new technologies, which they will grow.

Trump knows about the importance of good gas cone. They spend most of their time in the Palm Beach Beach Club Club, which does not exist without it. So it will do well to remember: You can air the 19th hole in the air but not the golf course. And it starts out very hot outside.
