What is coal?

Coal formation All living plants store solar energy through a process known as photosynthesis When plants die this energy is usually released as the plants decay Under conditions favourable to coal formation the decaying process is interrupted preventing the release of the stored solar energy The energy is locked into the coal

How a Nuclear Reactor Works

In most power plants you need to spin a turbine to generate electricity Coal natural gas oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine Nuclear plants are different because they do not burn anything to create steam Instead they split uranium atoms in a process called fission
