Why heaters are the future of cooling

A huge number of people still heat their homes with fossil fuels. There’s a better way. Subscribe to our channel! http://goo.gl/0bsAjO Experts call it the “cold crunch.” As temperatures rise in regions that historically haven’t needed indoor cooling, global demand for air conditioning units is expected to skyrocket. Indoor cooling is already the fastest-growing use of energy in buildings. But the emissions associated with cooling buildings are still tiny compared to the emissions from heating them — and that’s because while air conditioning uses electricity, our heat is still largely generated by burning fossil fuels. The way we heat our homes and buildings is one of the biggest contributors to climate change. But a solution may actually come from the rush of consumers looking to buy AC for the first time. They’re a huge potential market for a different kind of system — the electric heat pump. A heat pump works like a two-way air conditioner, using electricity and a chemical refrigerant to transfer heat either into or out of a building. Instead of using fossil fuels to generate heat, it uses electricity to transfer heat, and it does it efficiently. And if heat pumps are widely adopted, they could make a major impact on the carbon emissions generated by buildings.

  1. Some of you have pointed out that Technology Connections also has a video on electric heat pumps! Alec actually has two, the first of which you can watch here: https://youtu.be/7J52mDjZzto

    His videos go much more in-depth about how heat pump technology actually works. Our goal was more to explain the connection between two separate climate stories: the booming need for home cooling, and the opportunity that presents to drastically cut our heating emissions. Both stories have a lot more to them than what we could get into in this video, which we hope is just a starting point!

    1. heat pump market is far bigger than your graph in this video, half of homes in norway have them installed working mostly at heating. they also work very well down to -20C

    2. Repent to Jesus Christ
      “Be devoted to one another in love. Honor one another above yourselves.”
      ‭‭Romans‬ ‭12:10‬ ‭NIV‬‬

  3. In Europe, these are very common in more rural areas. On summer days, they can use up all the excess electricity solar panels are producing and even in the winter, they are still way more effective and climate friendly than other types of heating, especially in countries with a lot of hydro or aeolic power. In cities though, the “coolest” new tech in town is sending a cold coolant through the heating grid and thus providing cooling remotely, especially for commercial and public buildings

  4. Solar and wind will never be able to meet the demand now or in the future for our energy needs. But keep building those EV’s.

  5. the future of cooling is more insulation with less co2 production during the production of the insulation. cooling isn’t a solution at all.

  6. Compare with data from 1500 Mediveal Harm Period.
    And the Hot Summer of 1920s and 1930s !!!! Below -15ºC outside, heat pumps dont work !!!
