According to the American media, air conditioning was very rare in China. According to a report from the International Energy Agency, China now has more domestic air conditioners than any other country in the world. Air conditioner sales continue to grow.
On May 23, the US quartz financial website published a report titled "There Are Huge Hidden Costs in the Explosive Growth of China's Air-Conditioning Market," reporting that China's current electricity for cooling is 68 times that of 1990, and this number is still Faster than anywhere else continues to grow.
According to the report, at present, in all countries in the world, the United States still has the highest energy consumption in air-conditioning equipment. By 2016, 40% of the total installed air-conditioning power in the United States was in the United States, and 238 million inhabitants in the United States consumed energy for cooling. More than the combined cooling energy consumption of 4.4 billion inhabitants in Africa, Latin America, the Middle East and Asia (excluding China).
The report stated that, however, the United States will soon be replaced by China because the US energy consumption in air-conditioning equipment is now only modest, while China's energy consumption in air-conditioning equipment has surged.
The report pointed out that as of now, the number of air-conditioning equipment in China has exploded more than any other country. In other hot climate areas, the number of air conditioners is also growing rapidly. In the past, air-conditioning was very rare in these places. For example, since 1990, India has been The energy consumption in cooling has increased 14 times.
According to the report, on a global scale, the annual energy consumption of air-conditioning equipment accounts for about 10% of the total annual energy consumption of humans. Producing these electrical energy for air-conditioning equipment will significantly increase the greenhouse gases that will change climate in the atmosphere.
According to the International Energy Agency, carbon emissions from refrigeration have tripled since 1990, reaching 1.13 billion tons in 2016, close to the total carbon emissions in Japan that year.
The IEA expects that if the global cooling boom is allowed to continue without control, by 2050, the above figure may be doubled. By then, the global air-conditioning energy consumption will be equal to China's current total electricity demand. The International Energy Agency said, If no measures are taken to increase the efficiency of air-conditioning or to use renewable energy more, this may prove to be a catastrophic effect on global carbon emissions.
