New paper shows heat pumps suitable for all European countries - even cold ones!

Research out today in @Joule_CP by myself, @janrosenow and @heatpolicyrich at @RegAssistProj with Neil Hewitt.

We collected real-world data across 3 continents. 🧵

cell.com/joule/fulltext… Our research looked at field testing of around 550 heat pumps with more than 2760 measurements.

These data showed the coefficient of performance (COP) – basically, how well a device transforms one unit of energy into useful heat – related to the average outside temperature.

Do heat pumps perform well in cold weather?

❄️YES.🔥

We've been digging through virtual stacks of studies to find the numbers for an upcoming article.

Data from 🇫🇮🇩🇪🇨🇭🇺🇸 in the thread.

We'll keep adding to this as we find more @janrosenow

📸 @joesmyth First, a reality check. The coldest countries in Europe have the most heat pumps per household. nature.com/articles/s4156…

Why? Because they work well below freezing and can even see high efficiency levels.

Elon Musk has another terrific idea. He wants to ramp up US oil and gas production to reduce the world's dependence on Russian fossil fuels. Apparently, almost 500k people agree with him.

Lowering oil and gas demand is the quicker and cheaper solution to use less Russian gas.

And, yes, sustainable solutions like renewables, electric cars, heat pumps, and efficiency can be rolled out faster than new drilling.

“Energy now is moving from just a green issue, it’s clearly becoming a broader societal issue, including self-reliance and the importance of being able to have resilient energy infrastructure" @BlackRock

That's been the point the whole time.
smh.com.au/business/banki… For most, reasons for building renewable energy usually center foremost around the environment and climate change. The reasons are obvious.

But, until now, it seems like the general public hadn't understood what clean energy means for national security and global stability.
