Renewable Energy

Renewable Energy

1. Energy

   • A measure of the ability of a system, to provide work by means of motion, light, heat, by non-mechanical means
   • Renewable Energy
     • They are created in a continuous flow and dissipate through natural cycles that are estimated to be inexhaustible, since their regeneration is incessant.
   • Non-renewable energy
     • They are stored underground or terrestrially for millions of years, and they have the characteristic of being a finite resource.

2. Historia

   • The first achievement that arose was the use and mastery of fire.
   • Century (XX a.C)
     • The sails were used to capture the energy of the wind to later emerge the water wheel and the windmills, which later constituted the main source of energy in the European continent during the Middle Ages.
   • Century (XVIII)
     • The first experiments of using steam as a source of energy are carried out.
       • One hundred years later James Watt builds the first "Steam Engine"
   • Middle of the century (XIX)
     • The main energy source of that time was wood.
   • Beginning of the century (XX)
     • Vigorously increase energy use.
   • Year 1859
     • The first oil well is drilled in the United States of America, so as a result of this, a large number of inventions that use this energy source begin to be produced.

3. Use of renewable energy

   • Solar thermal
     • -Generation of electricity through renewable energies. -Generation of hot water for indoor or outdoor pool heating. -Underfloor heating or radiators. -Producción de agua caliente sanitaria
   • Solar photovoltaic
     • Heating- Lights-Pool-Heaters
   • Wind
     • Water pumping, grain milling and electricity generation.
   • Geothermal
     • Heating, hot water in homes, greenhouses and livestock facilities or in absorption cycles in agriculture for drying products.
   • Hydraulics
     • Electricity generation in hydroelectric plants, through water flows in water transport pipes, through the use of tides, sea currents, river currents or others, through the use of sea waves.
   • Biomass
     • Provides electricity, hot water, hot air, or heating.
