are things like oil,natural gas and coal. They cannot be easily replaced,because they have taken millions of years to form.

ex. are wind power,wave power,solar power,and biofuel can be easily replaced and will not run out.

it includes coal,gas,oil,and nuclear power

_________ and _____ are sometimes known as fossil fuels. _________ are finite resources they will not be around forever . _________ is also considered a non renewable energy source.

Earth's crude _____ and natural _____ is formed from Marine plants and animals that died millions of years ago.
