The alternatives to burning coal for electricity generation are:Water (hydro power) if availablenuclear energybiomass and geothermal energyrenewable energy sources as solar and wind energy.
It depends to the countries and what resources they have. Some alternatives to coal energy could be using oil, gas and even atomic energy in some cases.
oil alternative is carrots, apples, and other fruits

there are many alternates to coal like wind power, solar power, geothermal, and there are other fossil flue alternatives like gas or propane.
