That's 50% of electricity, but not 50% of energy. Coal still provides ~80% of energy IIRC (roughly 10% is carbon-free and growing faster than the US). China burns so, so much coal, while much of the world has shifted to natural gas, which has much less carbon per energy.
You don't recall correctly. Coal is also 50% of energy. It's used a lot for heating, but that is dropping rapidly. It's used in manufacturing, but that is also doing rapidly, except for steel. It's not used for transportation.
