I think the most common way to generate electricity is from fossil fuels like coal and gas. Another way to get electricity is from hydroelectricity. Wind energy is the third most common energy resource.
Coal is very common. Caves are a good source of coal, but if you are mining, coal is most common at y=48.
To make electricity, the most common way is to burn something that heats water that creates steam that runs a fan/turbine. Coal fired electricity is when the thing that is burnt is coal.
Peat is sometimes considered a type of coal-so surely it must be seen as the most common. There is a lot of bituminous ("soft") coal. Anthracite ("hard") coal, which produces less air pollution, is less common.
