I guess you mean renewable sources and non renewable sources.

Energy resources that are abundant in supply or are regularly formed and replaced through natural processes are called renewable sources. Example: Solar Energy.

Energy resources that have the potential of being exhausted because they are being used by people at a faster rate than they can be replenished by nature are called non renewable sources. Example: Coal.
