Around 23% of the electricity generated in the US comes from burning coal.
Approximately 23% of the US energy supply comes from coal.
Thermal energy I suppose, but in most cases it is used for electricity. The steel industry uses coal (or coke rather) in blast furnaces.
In electricity production, it is just under 50 percent
Coal produces energy through combustion where heat is generated by burning coal in a furnace. The heat produced converts water into steam which drives a turbine connected to a generator, producing electricity. Coal is a fossil fuel that releases stored energy when burned, making it a primary source for electricity generation in many countries.

For electricity it is still coal, at about 50 percent. For transport it is oil.
Coal - about 50 percent of total
Could be the total of coal and nuclear
The energy source you mean must be coal, but you seem to have two questions mixed together
35% of the world's commercial energy is produced from coal
