Renewable energies are sources of inexhaustible and clean energy. They are different from fossil fuels mainly because of their diversity, abundance, and potential for use anywhere in the world.
Due to its great importance in the environmental field, we carry out a top 5 with the renewable energies that are essential for climate change and other problems such as the production of greenhouse gases to cause less impact in our world.
- Undoubtedly, the sun is the star that we humans can appreciate the most since its energy is so abundant that it is considered inexhaustible, because to this day, the sun has 5 billion years emitting solar radiation and as calculated, has not reached 50 percent of its existence yet.
- Solar energy is a renewable energy obtained from the use of electromagnetic radiation from the sun and that could ultimately help solve some of the most urgent problems we face on the planet.
- The amount of energy that the Sun pours daily on Earth is ten thousand times greater than that consumed per day in the entire planet.
- The main technologies are solar photovoltaic (takes advantage of sunlight) and solar thermal (uses the heat of the sun).
- The already famous photovoltaic solar panels are a tool that takes advantage of this renewable resource.
- Wind energy is the energy obtained from the wind, takes advantage of the strength of this element, being the largest source of electrical energy in the world.
- The wind is also one of the oldest resources exploited by humans and is the most efficient and mature energy among all renewable energies.
- Wind energy consists of the conversion of the energy produced by the movement of the blades of a wind turbine driven by the wind into electrical energy.
- Also known as biomass, bioenergy is all organic matter present in the earth that when burned, chemical energy is released in the form of heat.
- In other words, it is a type of renewable energy produced from the use of organic and industrial matter formed in some mechanical or biological process, generally of the substances that constitute living beings or their remains and residues.
- Its most known forms are Biofuels: Biodiesel, Bioethanol, and Biogas or Biomass.
- It is a type of renewable energy that is obtained and uses the existing heat in the subsoil and that is found in volcanoes, geysers, hot springs, obtaining sanitary hot water in an ecological way.
- The applications of geothermal energy depend on the characteristics of each source. The geothermal resources of high temperature (from 100 to 150ºC) are used for the production of electricity mainly.
- When the reservoir temperature is not sufficient to produce electrical energy, its main applications are thermal in the industrial, services and residential sectors.
- This type of energy takes advantage of the force of water – from rivers and seas – to transform it into electrical energy without requiring any external power source.
- To take advantage of the energy of the water there are different conventional technologies (hydroelectric power plants with regulation, passing and pumping, and tidal power plants), and unconventional (hydrokinetic turbines, wave devices, osmotic power plants, and power plants).
- For the generation of electricity, a dam is constructed that stores water in an artificial lake, leaving the other side with less volume.
All these are energies that we must take advantage of as we reach because we must all be part of an intelligent act before having to think about solutions to problems.
