Why Heat Pumps are Immensely Important Right Now
Why Hacker News recommends it
HN's default link for anyone asking whether heat pumps work and why they're efficient, thanks to the presenter's clear and enthusiastic delivery.
What it is
Technology Connections explains why heat pumps matter right now, covering their efficiency, how they hold up in cold weather and the energy savings over burning fuel. It follows his earlier explainer on how they work.

Technology Connections on Youtube has a great video series on how heat pumps work, why they're important environmentally and what kind of power cost savings they can bring. The second video is a longer guide for people who want to get a heat pump. [this video] [LINK]

This is not true since the vast majority of electric whole home heating units sold today are heat pumps, which are up to 300% efficient [1]. If the power generation and distribution is 33% or higher efficiency, then a heat pump will outperform a natural gas furnace operating at 100% efficiency. EDIT - Here's a video that explains it much better than I could, although it's a bit long, this YouTuber is great. [2] [1] [LINK] [2] [this video]

Yes, apparently there have been huge advances in the efficiency of heat pumps since then. And this is why ground source heat pumps are less of a thing these days: you don't need the help of that underground temperature as much. This guy gets really excited about heat pumps: [this video] [LINK]
