The Cruel Irony Of Air Conditioning



Thanks to the University of Minnesota for sponsoring this video!
The technology we use to keep cool is heating the world in a vicious feedback cycle, so we need to improve it and use it less.

Thanks also to our Patreon patrons and our YouTube members.

  1. Thanks for watching! Viewer support makes MinuteEarth possible. Will you become our patron on Patreon or member on YouTube? Visit https://www.patreon.com/MinuteEarth or click "join" here on Youtube

  2. What if it's winter? You don't use air conditioner you just use heaters you mostly use air conditioner for like summer or spring I think the cold Last longer then spring and summer

  3. Bull Shit. Thermodynamics says we cant make or destroy energy. If we used the energy of AC somewhere else, heat wouldve been generated by the other law of thermodynamics and the house itself got colder and stole back the warmth from the air. Global warming exist yet, bigger problems are the cause of this problem ie corpret greed, deforestation, just to name a few so PLEASE stop fixating on a lesser issue

  4. Technically the air conditioner outputs even more heat outside than it sucks out of the room, cause it generates some heat in the process of "pumping" heat from colder environment to hotter one.

  5. People protesting against climate change need to stop using air conditioning otherwise they aren't committed to changing, themselves.

  6. As someone who works as system planer, engineering technical equipment for buildings, I can say that most of the people who live in temperate climates don't actually need air conditioning. Heating and window ventilation enough create a comfortable living climate. In Germany for instance, air conditioning is only common in hotels. Nobody uses them in the private sector, unless you don't own a passive house. Unfortunately, like everywhere else, we humans are very lazy and therefore want to let everything work automatically. By doing that, we also increase the risk of diseases and allergies, because we are constantly surrounded by perfect air and can no longer bear the slight impurities and temperature differences. Making everything perfectly clean, doesn't keep you healthy.

    I like how the refrigerant leaking out is color coded to the two most common types of refrigerant in residential systems. R22 and R410a. (color of refrigerant tank)

  8. The main issue is still 100 companies produce over 70% of the worlds Climate change. So even if we did deal with the AC issue thats still 30%. We cannot fix this without government intervention on corporations

  9. I appreciate how these videos offer solutions / alternatives that individuals (as well as policy makers and institutions) can implement. Keep on educating and promoting change!

  10. Im considering going back to using fans ive had a window ac since 2012 it no longer turns off when my room gets cold enough (have do that manually) & recently it started draing rain water & condensation into my room instead of outdoors but the biggest reason is because it takes up window space & im afraid its gonna fall out the window & crush 1 my cats.
