I have accounted for all the renewables mentioned in the linked wikipedia page, which covers sources as insignificant as hydro (<1%). What else is there? Have you thought about updating wikipedia with whatever you think is missing?
Ignoring French nuclear imports
That would only increase the proportion of fuel energy even more, which only works against your botched claim. If you want to count French nuclear, then the portion of solar, wind, and hydro is proportionally even less. Brussels currently has a nuclear power plant inside the region. Why do you think it would it be sensible to transmit over such distance? That would introduce even more substantial inefficiency in the transmission.
Ignoring current state but talking about possible future plans
The status quo only has 1 year left on it. And nuclear power still has the same stages of energy transition loss you’ve failed to debunk. What’s the point? Your claim is nonsense either way.
No you haven't. Read your own source. Hint: biogas
biogas was used in 2009, not in 2020 when the stats were collected. Nor would it matter if it were still used. Hint: it would be an increase on the 80%.
recall: fuel energy → heat energy→ steam → turbine → transmission → heat energy
Also, nuclear fuel is not gas, so this speaks for electric stoves, silly.
That’s fuel. That’s in the 80%.
again: fuel energy → heat energy→ steam → turbine → transmission → heat energy
