Electricity generation using coal involves burning coal to produce steam, which drives turbines connected to generators. This process releases greenhouse gases and pollutants, contributing to environmental concerns. In contrast, hydroelectric generation harnesses the energy of flowing water, typically from rivers or dams, to turn turbines and produce electricity. This method is considered more sustainable and environmentally friendly, as it relies on renewable water resources and produces minimal emissions.

Coal.
Coal is the largest source of energy for the generation of electricity contains mainly carbon, the conversion of dead vegetation into coal is called carbonization.
Coal is abundant and easy to convert into electricity.
When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines which turn generators and create electricity. Old coal power plants, especially "grandfathered" plants, are significantly less efficient and produce higher levels of waste heat. About 40% of the world's electricity comes from coal, and approximately 49% of the United States electricity comes from coal.
Because the burning of fossil fuels is causing global warming. We have plenty of coal around the world but we have to stop using it now because of future generations of people (as well as future generation of electricity!).
A coal-fired energy plant is one that burns coal (as the source of energy) to make electricity or drive machinery.

Today, the main use of coal in the United States is related to electricity generation and industry.
