“Putin switched off the gas. He cannot repeat that with the sun.” Great quote @KadriSimson @Energy4Europe! Sums up the critical role of renewable energy for European energy security. ft.com/content/16031b…
@janrosenow has co-authored an important article on how governments can play a positive and active part in advancing industrial electrification. Lots of great ideas and info in this article for the @wef ⬇️.

This excellent quote by British philosopher Bertrand Russel sums up my experience with social media in one sentence.
Electrification in the US is still in its infancy. There is huge potential for electrifying much of industry, buildings and transport. (White font in graphic represents electrified part of energy use.)
"Will we be warm?" I was asked last night by a friend thinking of installing a heat pump in an old not well insulated Victorian house. My response: "Yes you will." Heat pumps can work in any building if sized, designed and installed correctly. 🧵 carbonbrief.org/factcheck-18-m…

@janrosenow So the Dunning-Kruger effect should really be called the Bertrand Russel effect.
Pretty much. FWIW I think the wiser people have had enough.
This excellent quote by British philosopher Bertrand Russel sums up my experience with social media in one sentence.
It's called the Dunning Kruger Effect. Very common. Particularly around here.
This excellent quote by British philosopher Bertrand Russel sums up my experience with social media in one sentence.
@janrosenow True. Education and life experiences teach you to see both sides of an argument.
@cutnoise @janrosenow perhaps because you have to include "potential" in that noise claim? Just because it is possible to have a noisy installation does not mean that all installations will be noisy.
@danmmeyer @janrosenow @NotTheSame_Cord l live in Canada, and we heat our fifty-six year old, 2,600 sq. ft. Cape Cod almost exclusively with two 12,000 BTU/3.5 kW ductless mini-splits that do not have emergency heat.
@NotTheSame_Cord @danmmeyer @janrosenow The older of our two ductless mini-splits (an inverter model) is now in its sixteen year of operation, and there have been no issues thus far. The other was replaced with a high efficiency model in 2022 that uses one-third less energy and works efficiently down to -25°C.
@NotTheSame_Cord @danmmeyer @janrosenow I can only share my own experience which has been highly positive. Worth noting that over one-third of the homes in our province currently use heat pumps as either their primary or secondary heat source, and that number is continuing to accelerate with each passing year.
@janrosenow We have a 14kw Mitsubishi Ecodan and it does a great job of keeping our 150yr old stone house warm. Use radiators rather than underfloor heating but such an improvement on the old oil boiler!
Well, that’s a wrap after more than six years at @theCCCuk. It has been a wonderful privilege. The handle of this account will change shortly, but please continue to follow. I’ll keep tweeting on climate when I move across to @thecarbontrust from next week. 🙏
@janrosenow I think you might enjoy this recent case study featuring @_ChiefGeek that illustrates how a well installed heat pump can provide a SCOP of >4 in a house with single skin walls and only easy and practical upgrades to insulation. youtu.be/XCMaup9Eosw?si…
@janrosenow @IEA Very similar vibes to this old favourite...
Es gibt keinen physikalischen Grund, warum Wärmepumpen nicht effizient im schlecht gedämmten Altbau funktionieren sollen. Natürlich braucht man eine größere WP. Aber man bräuchte auch eine größere Gastherme./2
"Will we be warm?" I was asked last night by a friend thinking of installing a heat pump in an old not well insulated Victorian house. My response: "Yes you will." Heat pumps can work in any building if sized, designed and installed correctly. 🧵 carbonbrief.org/factcheck-18-m…
@janrosenow Investors are wise people and want a good long term return on their money. Where would an investor in energy put their money? The declining fossil fuel generating market with exposure to the effects of wars and dictators. Or, renewables and storage with free fuel forever.
@milachka2001 @janrosenow @AbigailDombey Beyond how “much electricity do we get” the next question is what do we use this electricity for. If grid growth is transport (BEV) or heating (heat pumps) then there is a second multiplier to add 1 unit of energy put towards electrical transport will save 4 units & heating 3.5
