They cool vaccines, blood for transfusions, and temperature-sensitive medications, as well as the data processors and computer servers that make up the internet—everything from the cloud to blockchains.
In , annual global warming emissions from HFCs were the equivalent of million metric tons of carbon dioxide. Experts agree that a swift end to HFCs could prevent as much as 0. Yet regardless of the refrigerant used, cooling still requires energy. According to the U. Energy Information Administration , air-conditioning accounts for nearly a fifth of annual U.
This is more energy for cooling overall and per capita than in any other nation. Most Americans consider the cost of energy only in terms of their electricity bills.
Renewable energy infrastructure can take us only so far. The rest of the work is cultural. Comfort cooling began not as a survival strategy but as a business venture. It still carries all those symbolic meanings, though its currency now works globally, cleaving the world into civilized cooling and barbaric heat.
Despite what we assume, as a means of weathering a heat wave, individual air-conditioning is terribly ineffective. It works only for those who can afford it. And, of course, air-conditioning only works when you have the electricity to power it. During heatwaves, when air-conditioning is needed most, blackouts are frequent.
The troubled history of air-conditioning suggests not that we chuck it entirely but that we focus on public cooling, on public comfort, rather than individual cooling, on individual comfort. And to comfort. Privatized air-conditioning survived the ozone crisis, but its power to separate—by class, by race, by nation, by ability—has survived, too.
Comfort for some comes at the expense of the life on this planet. Contact us at letters time. Back To Home. Air conditioning units installed outside of a shopping mall in Mumbai in May By Eric Dean Wilson. While other subway passengers perspire in the warm and humid underground station, Paul Forman appears cool and comfortable in the experimental air conditioned train, which made its first run in New York City, in July The test run included six air conditioned cars and two old cars.
When the train left Grand Central Station, the temperature was 89 degrees in the old cars, while the new cars registered a temperature of A theater's lobby advertises air conditioning to prospective movie-goers. Angela Eaton grooms "Dutchess" inside "House Calls" trailer in Keeping cool with better design There are other ways of keeping cool that are also better for the climate.
Video ABC. Better neighbourhood design is also another way of keeping cool. Urban heat islands appear in areas with lots of pavement and not many trees.

Design neighborhoods with cooling temperatures in mind. Typically when suburban areas are subdivided and developed, trees get removed.
Trees bring shade to footpaths and your yard, but they also reduce the heat load on a building. Walk barefoot across some concrete without shade to feel the effect, then move to an area that has shade because of nearby trees.
Plant more trees, especially on the south side of your house if you are located in New Jersey, to increase canopy cover. That gap is the AC. The combination of high demand and extreme temperature can cause parts of the system to overheat and fail, leading to blackouts. In , equipment failure left , people in Queens without power for a week , during a heatwave that killed 40 people.
It is important to reduce the carbon based energy used by buildings, especially because an increasing proportion of that energy consumption is being used by air conditioning. Renewable energy can offset some of the damage. Solar, wind and hydroelectric power are more available than ever before and have little to no negative environmental effects, harnessing the power of nature for clean renewable energy.
Solar panels provide clean, continuous energy with absolutely zero negative impact on the planet. Having these wired into your heating and air conditioning equipment could help save both money and the planet.
Once developers could rely on maintaining comfortable indoor temperatures by using heating and cooling technologies, they often built less energy-efficient homes , which means that you rely more on air-conditioning or heating to get to your desired temperature. A badly insulated home bleeds energy and money and it is estimated that a well insulated home saves 1, times the energy of a non insulated one.
Obviously, air conditioning is not all bad. There are obvious benefits of a cooler, dehumidified air, as well as healthier and more comfortable living. Newer models use less energy and are fueled with safer, cleaner refrigerant.
Air conditioning also impacts the environment in a positive way in the manufacturing world. Workers are much more productive in a climate-controlled environment, resulting in less wasted time and energy consumption. Planting trees, retrofitting old buildings with proper ventilation, and building more efficient buildings that can better withstand a heatwave are Among the higher priorities.
Without building a new house or planting more trees, what can you do to keep cool in a more sustainable way? When you do use the air conditioner, make sure to shut all the windows and doors to seal the house. Even just turning the temperature up a few degrees can make a big difference.
