It is plentiful and cheap.
Coal is preferred energy source.
One of the uses of coal is for power.
The good about coal is that it is a source of energy while the bad is that it pollutes air.
maybe it does because it does have some problems with oil and coal and will fill certain parts of the world in centuries
The main advantage of solar power plants is how good they are for the environment by releasing no greenhouse gasses like fossil fuels do. Also the energy source from the sun is not going to run out like coal and oil will.
Electricity is generated in power plants; those power plants need some energy source. One option for such an energy source is fossil fuel like coal, oil, and natural gas.
Communities all come together when a coal mine disaster occurs. Some coal barons donate magnanimously to their favorite charities, especially to congressmen unimpressed by the science of anthropogenic global climate change.
I don't know a lot about it, but there are a lot of coal power plants, probabley to use the coal for some kind of energy source (like they use to do on old trains where they put coal in the fire.
In Europe they replaced it with wood! Which I think is very strange!( in some ways )
Natural gas is abundent, cheap, clean, and relatively safe.
It keeps me in a job !!
Conventional sources of energy usually include coal and oil - these have been used for many years. Natural gas is more recent, previously gas for cooking and lighting used to be made from coal. Coal has been used for centuries especially in Europe, whereas oil is a more recent development, mostly in the last century. Before that, transport was mostly fuelled by coal.
