   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.
