That's still only around $100 a year in electricity assuming 10 cents/kWh.

In Germany, regular prices scratch 30 cents/kWh, so you're looking at another 25€ a month just to run the dish.

A regular unlimited Gigabit Uplink runs 40€-80€ a month, with hardware included and a power usage in the range of 10W.

But, unfortunately, anywhere you have a Garden large enough to host starlink, you probably won't have anything near that speed available, so it's still pretty competitive.

:(

Living with more space though, you can offset that with solar pretty easily.
