Energy classification.

The energy classification is divided into two groups: renewable and non renewable energy.

– The renewable energy resource is energy extracted from natural sources like biomass, geothermal heat, tides, sun, wind which are naturally replenished. They can be replaced and generated with more “frequently.”

– The non renewable energy resource is a natural resource which cannot be generated, produced or use without caring it. Once it has finished, there isn’t remaining. They are consumed faster than the nature creates them.
