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
Luckily you don’t need to burn uranium to avoid 5 steps of energy transformation.
