Energy resources
The energy we use on earth originally
came from the sun.
Hundreds of millionsof years ago, when the earth
was partly covered with swampy forests. As the plants
died and fell to the ground a layer of dead plants at the
bottom of the swamps was covered by layers
of water and dirt, trapping the energy of the
dead plants. The heat and pressure from the top
compressed the layers making the plant remains turn
into what we today call coal
Oil and Gas were formed when animals and
plants living in the seas died and were covered in
mud. The mud was compressed in the same way
as dead plants were compressed to form coal
plants living in the seas died and were covered in

Coal, Oil and Gas are known as Fossil
Fuels and because they were formed
hundreds of millions of years ago they cannot be
replaced as they get used up, they are known as
Non Renewable Energy Resources
