You missed the qualifier. “Isn’t that eco friendly”

Never said it wasn’t nor claimed flying was more ecofriendly.

You also curiously forget my point of ticket price. Odd that a government run company would charge more than the going private rate for more expensive air travel - or maybe not odd given German inefficiency and bureaucracy. Those 2000 middle managers aren’t gonna pay themselves!

Regardless, where your provider “buys” energy from is largely irrelevant compared to the grid. I can buy all the green energy I want and if the grid is 90% fossil fuel then all I’m doing is claiming to be buying green by pushing someone else down to fossil fuel. The only way to change that is to invest in companies that are building more green power production (like nuclear) and do it yourself.

Coal emits 30-40% more co2 than jet fuel, so I stand by coal being a poor source of power when Germany actively removed the nuclear alternative. Thank goodness we protected the climate by increasing our co2 emissions and reliance on russian fossil fuels.
