15 examples of renewable and non-renewable energy

All movement or change on the planet and in the entire universe are generated by sources or forces that act on it, that is called  energy,  which transformed is visualized in all senses, from a moving body to a simple battery. There are two types of vital energy for our growth and development called energy  renewable and   non – renewable.

Renewable energy  is provided by mother nature. With an infinite capacity for exploitation thanks to its source of origin, it is considered clean and free of residues.


  • Solar Energy:  Produced by the largest star, better known as the  sun . Through this type of energy, light and heat are obtained. The most efficient way to achieve it is by  solar panels .
  • Geothermal Energy: It is obtained from the bowels of the earth. Despite the lack of sufficient technology to use this important resource, we know that it is used to obtain  hot water in spas and for  industrial purposes.
  • Biomass Energy:  It is a type of energy that is extracted from  organic matter , generally from living beings.
  • Hydraulic Energy: Obtained through the  force of water , through natural or artificial falls or waterfalls such as dams. This type of energy is exploited by hydroelectric sources.
  • Wind Energy:   Energy produced by  air currents.  Currently it is developed through  wind turbines  or mills located in wind farms arranged in certain areas to be able to subtract this resource.
  • Tidal Energy:  Generated by the tide, it is used by turbines found at the bottom of the ocean, deep rivers or at its mouths, connected to generators located on the earth’s surface, thus generating clean energy free of waste.


It is the energy that we use conventionally, it is characterized by its limited duration since the reserves that exist are counted and after the reserve is finished there is no way to replace or create it. This type of energy is considered highly polluting .


  • Petroleum:  It is the one commonly used in the world, known as a fossil organic compound , extracted from deposits located at the bottom of the earth in order to generate energy.
  • Coal:  Organic mineral  existing and managed for millions of years by man. It is generally used in thermal or thermoelectric plants.
  • Natural Gas:  It is obtained through the exploitation of oil and goes through various chemical processes to finally be used.
  • Nuclear Energy:  It is achieved through the division and union of an atom that generates physical and chemical reactions releasing a large amount of steam or thermal energy that is converted into electrical energy, immediately after passing through specialized turbines for such work.


  • Wind energy through floating wind turbines

This novel and interesting idea is based on placing large windmills in the air and connecting them to transformers on the earth’s surface in order to distribute clean energy and thus reduce the large areas of land currently occupied by the mills.

  • Energy through seaweed

Its purpose is to create biofuel through terrestrial vegetables. By drying seaweed, carbohydrates are extracted that are later converted into sugars, resulting in organic , economical and sustainable fuel .

  • Drone power

Recent studies raise the possibility of placing solar panels with drones , so that they are in an exact position without affecting or deteriorating the source due to bad weather and would send the energy to the earth’s surface through wireless networks .

  • Hydrothermal carbonization

It consists of using  organic waste by subjecting it to high temperatures and transforming it into  hydrocarbon  or  biochar , depending on the intervention of water.

  • Energy obtained from recycled waste

Its main function is to obtain energy through the processing of waste either by combustion or decomposition.
