Can We Keep Warm and Stay Cool Without Fossil Fuels?: Crash Course Climate & Energy #5

1. -20°c is nothing for a Canadian…

2. HARness. Are you Canadian?

3. Fracking can also push flammable gas into peoples drinking water. There are many videos of people putting a match to the water running out of their faucet and getting big fireballs.

4. Talking about AC & inequity, it should be mentioned that the vast majority of countries around the world have little to no AC, no matter what the temperature is, we just make do with the heat, sometimes at deadly levels. At some point it's not just about finding solution to decarbonize, it's also about limiting the energy consumption of wealthy people who think their comfort is normal & they won't relinquish it. Hearing "my love of frigid temperatures" makes me think about how the North America has AC in public places & private homes for around the year use to regulate tempature, when even in Europe we only have mostly heating system we put on for the winter, usually collective system that are regulated to be what is needed & nothing more or individual heaters that are so expensive in electricity that we limit the use to the minimum & we are told not to waste electricity, to only heat it at 19°C when we are there, the rest of the year the temperature just is what it is & it's already a luxury.
   It also seems to me that most of the discussion around housing heating & cooling revolves around updating isolation in existing housing & changing how we built homes so that we need less energy to heat/cool them in the first place. I'm very perplex this wasn't mentioned in this episode.

5. This video is so informative, thanks for sharing!!🙂

6. Yes Goddamn, of course! Remember Tesla all that time ago?

7. I hope hydrogen extraction from water gets more coverage later in this course. Sabine Hossenfelder did a video that surveyed all the battery storage options and hydrogen was by far the cheapest.

   This video refers to hydrogen and captured CO2 as electrofuels, but it isn't fair to lump them together. As pointed out, CO2 as fuel simply re-releases the CO2 that was captured while burning fossil fuels, cutting the CO2 emmissions in half but hardly eliminating them. Hydrogen, on the other hand, doesn't release CO2 when it is used for fuel.

8. Shouldn't we also be composting plant waste to maintain soil health and sustainable farming. Recycling waste water on the land is building up microplastics from laundry water with debris from synthetic materials.

9. More needs to be discussed on this topic and new technologies for home temperature management..

10. The thing is that when a kompany mus pay more for emissions we must pay aswell more for energy . You cant charge company without charging ourselves. In the end it will end up to not affording commodities such als heating in the winter . It is alredy hapening and the fact that we pay more for gas does not change the CO2 outcome . For the better . Just more money from us to the gas companys wich ends up in the States budget .

11. Loving this series! But, is it just me or is the transition sound effect a lot more frequent in this than other Crash Courses? I've barely even noticed it before but here it's almost distracting.

12. As much as I love the series I was disappointed by this episode. There was barely any talk of passive heating/cooling as well as different types of architecture used. Instead we got a section on electrofuels- an objectively terrible decarbonization method!

13. Correction: your air conditioner already uses a heat pump. The replacement that you're talking about can both heat and cool because it's designed to use its heat pump bidirectionally. Shoutout to the Technology Connections channel.

14. Heat pump from the ground or burn wood lmao saved you all 14 minutes

    Charcoal if made in thee indirect(baked) process and the producer gas collected, Charcoal is just as clean as Natural Gas… Make it from Eucalyptus which matures in a very short time, scrubbing carbon as the same time. Win Win for the Poorer Nations.

15. I think it's important to mention with heat pumps that in certain climates, backup heat is a must, and that can be a deterrent. If I am going to need an expensive furnace or other heat source in my home during stretches where the daily high is -20°C, I'm not also going to spend the extra money to also install a heat pump.

    But I'm also not a fan of making the perfect the enemy of the good. For people on lower-carbon electrical networks in relatively mild climates, heat pumps are probably an excellent choice.

16. People that actually have solar panels know that it is almost impossible to heat or cool your house by solar. Most people that live off the grid on solar still have to have gas heaters and generators. Solar panels and battery tech is no where near reliable enough to heat or cool. More break throughs and at least 10 or 20 yrs of innovation is required before that can happen and then probably another 20 years for it to be affordable for everyone to use and that is not even factoring in that most of the rare earth minerals are mined by child slaves in third world countries or that we dont have a good way to safely get rid of the things when they don't work anymore. "Green energy" is still pretty much a pipe dream….

17. I've always been curious about climate friendly solutions to heating and cooling! Thanks for this 🙂

18. Where is her accent from?

19. burning coal for heat is more fuel efficient then burning coal for electricity for heat, however power plants can use massive filtration systems for the smog particles, I'm not sure how much CO2 can be filtered if any.
    all air conditioners are heat pumps and every AC I've seen works both ways(maybe its a regional thing) also car air heaters normally use the heat from the engine block (I assume it's different in electric cars)

    also I feel like interior insulation needs to be brought up as a way to make heating/cooling more energy efficient, it may not always be practical, but still important.

    otherwise great video 🙂

20. I have forward cycle natural air conditioning, i.e., a window, and the hot it is outside the hotter it is inside, and the cold it is outside the colder it is inside. Some of the issues maybe solved by better architectural designs of buildings. But mine is an old apartment block. I have gotten use to sleeping on the bathroom tiles on exceptionally hot days.

21. humans absolutely survived before heat, a/c and electricity, including thru an ice age.
    maybe modern humans have become too soft and weak to survive in nature without their technology and toys.
    maybe the only real solution is radically less humans, especially the spoiled ones.
    that seems like it would be easy to achieve if we just shut off the grid. 🤗

22. the best way to heat and cool is to go underground

23. Okay, 7% is a metric, but you'd think that the biggest concern for climate change would be something with a bigger share of CO2 emission totals. Ie: focus on the biggest changes first, worry about the little things later on.

24. tell this to bilionares, who flies with plains left to right. to companies as amazon… you will own nothing and will be happy. thanks, no!

25. Funny, i'm getting my new air to water heat pump tomorrow! Very expensive but also efficient. Heat pumps are very common here in the nordics.

26. Sadly missing efficiency… If you live in a well insulated building cooling and heating loads can often be many times lower than in other buildings that leak air, lack shading in summer / windows towards the south in winter, etc.

27. Wear minimal clothing in summer and put more clothes on when your cold instead of turning up the heat. Double the amount of insulation and ditch windows. If you want to SEE outside, GO outside.

28. Hot stuff! Cool!

29. Not to mention, fracking also causes earthquakes in nearby areas!
