Non renewable energy
resources are the fossil fuels (Coal, oil and natural
gas) and nuclear fuels.
Fossil fuels release a lot of heat energy when they are burned.
The Earth’s supply of fossil fuels (coal, oil and gas) and of
nuclear fuels is limited.
It
will take millions of years to replace the fossil fuels we have
used.
Most of the energy used comes from non-renewable fuels, mainly
from fossil fuels.
