Non-renewable energy resources!!!

A non-renewable resource is a natural resource which cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate, once depleted there is no more available for future needs. Also considered non-renewable are resources that are consumed much faster than nature can create them. Fossil fuels (such as coal, petroleum, and natural gas), types of nuclear power (uranium) and certain aquifers are examples. In contrast, resources such as timber (when harvested sustainably) or metals (which can berecycled) are considered renewable resources.

Fossil fuel

Natural resources such as coal, petroleum, oil and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed. Eventually natural resources will become too costly to harvest and humanity will need to find other sources of energy.

At present, the main energy source used by humans are non-renewable fossil fuels, as a result of continual use since the first internal combustion engine in the 17th century, the fuel is still in high demand with conventional infrastructure fitted with the combustion engine.

Radioactive fuel

The use of nuclear technology requires radioactive fuel. Uranium ore is present in the ground at relatively low concentrations and mined in 19 countries.^[2] The uranium resource is used to create plutonium,^[3] uranium-238 is fissionable and can be transmuted into fissile plutonium-239in a nuclear reactor. Nuclear fuel is used for the production of nuclear weapons and in nuclear power stations to create electricity. Nuclear power provides about 6% of the world's energy and 13–14% of the world's electricity.^[4] Nuclear technology is a volatile and contaminatingsource of fuel production, with the expense of the nuclear industry predominantly reliant on subsidies. The radioactive waste the nuclear industry collects is highly hazardous, for a prolonged period and storage has risks of containment. Radioactive fuel continues to be controversial and unresolved industry.
