A look at destatis tells me something else for Germany (in 2024): Solar has a share of 15 %, and wind 28 %. In total 57 % of the produced energy comes from renewable sources. (https://www.destatis.de/DE/Themen/Branchen-Unternehmen/Energ...)
They are trying to switch the conversation from electricity where renewables are making unmistakably swift progress, to all energy (e.g. gas for heat in homes and factories and oil for cars and trucks).
They think the horrific inefficiency of fossil fuels in these uses makes progress look slow and futile as it massively inflates the total energy usage.
In reality, once we get the easy bits of renewable electricity done and are at 80% carbon free electricity, these other markets let us avoid the hard part of getting to 100% clean energy but still make rapid progress on decarbonisation.
An EV or heat pump running on mostly clean energy is a 5 or 6x improvement in carbon even before you account for the grid benefits of having such a large amount of battery and heat storage attached to the grid.
I really want to see a heat pump being used to make a real world high temperature process more efficient and cut natural gas use by 40% or so, this might destroy the latest talking point
the problem with heat pump is require quite well isolated building to make it efficient. Also after talking with a friend he had to change all radiators in his parents home since it didn't work well with previous old one he had.
I'm also not sure if heat pump is a solution for multifamily apartments.

I think you're looking at electricity here, not energy. Energy is much more than electricity.
