How long will world's fuel resources last?

- Fossil fuels are non-renewable energy resources. Once burnt, they are lost. They have taken hundreds of millions years to form and cannot be regenerated in a short period of time

- There is a limit within which our fuel resources will be used up. Hence conservation is important.
