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.
This video shows us what solutions are in process and some of the effects which cause the non renewable energy resources. The video is until 1:44 minutes and after you can know who has done it.
