I recently came across this chart for our total energy consumption in Germany for 2024 and the biggest circle is the red one for fuel in the transport column. 644 TWh 🤯

Only about 20% of the energy in fuel is converted into movement, the rest is wasted as heat. (80% of 644 TWh = 515 TWh)

According to the Federal Environment Agency, all private households used 465 TWh to heat our homes in 2024.

Let that (heat)sink in: We produce more excess heat by burning fuel than we need for heating.

@bastianallgeier If you burn that oil in a modern power plant (45% efficiency), you would get enough electricity to cover the needs for transportation and heating the homes with heat pumps with an annual performance factor of 3.

@bastianallgeier Man könnte das Öl auch in einem modernen Kraftwerk (45% Effizienz) verbrennen. Mit dem dabei anfallenden Strom könnte man sowohl den Bedarf des Transportsektors als auch den Wärmebedarf der Häuser mit einer Wärmepumpe mit einer Jahresarbeitszahl von mir 3 decken.

@bastianallgeier This chart and these stats are eye-opening. We need more of this type of communication to spread positive messages about the benefits of switching away from fossil fuels.

Having lived with an electric car for a few months now, I'm more convinced than ever that it's a significant step toward solving the mobility puzzle.

Makes me angry that this is happening at a time when we have turned our train infrastructure into a giant mess. Fixing this is another big step.

@bastianallgeier wenn man jetzt noch bedenkt, dass Deutschland bewusst die CO2 Ziele im Transport Sektor nicht geschafft hat;
deswegen ein Gesetz erlassen musste, dass Überefüllung anderer Sektoren nutzt um die vom Transport auszugleichen

@binbash to be honest, I think that the commercial transport sector will electrify faster than the personal one.

@bastianallgeier I really hope so. Do you have numbers on unneeded truck tours that are done because they are cheaper than having a larger warehouse?

@bastianallgeier Huh. I guess this is why the heating in ICE cars is really effective.

@bastianallgeier “We could heat all our houses with the heat gas cars generate and do nothing with” should be a headline somewhere. And yet…

Energieverbrauch privater Haushalte

Die privaten Haushalte benötigten im Jahr 2024 etwa gleich viel Energie wie im Jahr 1990 und damit gut ein Viertel des gesamten Endenergieverbrauchs in Deutschland. Sie verwendeten mehr als zwei Drittel ihres Endenergieverbrauchs, um Räume zu heizen.

@bastianallgeier
You can also check the Ipcc report, and our world in data website to compare with the rest of the world.

There are many levers to change that, and we are globally not pressuring politicians and helping individuals to change it.
Most of what we do is crap for climate, and most people do not know how much for each thing, and what to do to change it.
