Like:- COAL,PETROLEUM AND
NATURAL GAS.
Electricity from coal is called

HYDEL POWER
Rain water or river water stored in dams is made to fall from
heights. The falling water flows through pipes inside the dam
over turbine blades placed at the bottom of the dam.
The moving blades then turn the generator to produce
electricity. This is called HYDRO ELECTRICITY.
