Detailed Solution

The given statement is true.
Concept: Non-renewable resources are those that are limited and may become extinct if used carelessly, whereas renewable resources are those that are regenerated naturally.
i) By categorizing the sources, we can gain insight into the constraints on how we can use particular resources that are in short supply. Non-renewable resources include coal, petroleum, natural gas, and other energy sources that cannot be supplied as quickly as they are used up. As a result, their usage must be controlled and restricted. Resources that can be used in such huge quantities and/or that are periodically replenished are considered renewable. Solar energy, tidal energy, geo-thermal energy, wind energy, etc. are some examples of renewable energy sources.
ii) Not all energy sources are sustainable and unendingly available, as was previously noted. Therefore, if they are to be preserved for future generations, their use must be controlled and substitute sources must be found. We can determine their geographic and statistical availability as well as their sustainability using the aforementioned classification approach. As a result, the use of resources that may soon go extinct might be restricted. Finding renewable resources and using them is made easier by gaining more expertise and information about alternative sources.
So, the statements are correct.
Hence, the given statement is true.
