In case anyone is curious, the sources I find suggest the following about the sources of the primary energy in the European Union:

~38% from oil, of which ~29% is from Russia = ~11% of total energy, plus

~24% from natural gas, of which 39--45% [note this is higher than in the parent comment] is from Russia = 9+% of total, plus

~14% from coal, of which 46--70% is from Russia = 6+% of total energy, plus

~11% from uranium (nuclear), of which ~20% is from Russia = ~2% of total energy,

altogether totaling >28% from Russia.

Other sources may disagree on the particular numbers, but the rough estimate of "one quarter" is in line with other sources: https://www.weforum.org/agenda/2022/04/europe-russia-energy-...
