Reply to comment by dontpet in The IEA says humanity used the greatest amount of coal in 2022 in all of human history, and that this level of consumption will continue until at least 2025. One-third of all global coal goes to generate electricity in China, and India's coal use is growing at 6% per annum. by lughnasadh

I read somewhere that electricity only accounts for around 30% of all energy usage. I hope this is outdated or a misunderstanding on my part. Can’t seem to find confirmation.

A mitigating factor when you consider energy instead of power is that somewhere between 30 and 50% of energy in most cases is expelled as waste heat. Those thermal power plants and vehicle transport energy cases shouldn't be compared one to one with renewables.

In a lot of countries the waste heat is used for district heating. Raising the system efficiency to 80-90%.
