In the midst of the conversation about the 2021 electricity reform, we have often heard about the the importance of clean energy and the good they can offer the environment, but what exactly are the benefits? What types of renewable energy exist? We tell you.
Importance of clean energy
According to Acciona’s definition, renewable energies are “clean, inexhaustible and competitive sources of energy”. The main reason why they are considered a better alternative to fossil fuels is that they come from natural resources, are diverse and have enormous potential for use in any type of territory.
Since clean energy can be obtained virtually anywhere, its cost is usually cheaper, which can have a positive effect on a country’s economic development.
On the other hand, fossil fuels are not renewable and their deposits are limited, which causes social and political tensions; In addition, its use generates a large concentration of polluting emissions such as CO2, one of the gases responsible for the climate change that we are currently facing.
If we take into account that the global demand for electricity will increase by about 70% by 2040, according to data from the International Energy Agency (IEA), we need energy sources which not only help us satisfy buying and selling, but also contribute to global warming, are cheaper and more efficient.
The the importance of clean energy It has been recognized in international bodies and treaties, such as the Paris Agreement, which sets an overall objective: to reduce polluting emissions in order to promote the energy transition towards renewable energies.
The main advantages of clean energy are:
- They do not produce polluting emissions.
- They reduce energy dependence, since each country can rely on its own natural resources to produce them.
- They are inexhaustible.
- Their competitiveness is growing, thanks to the fact that more and more governments and businesses are investing in them.
What types of clean energy exist?
Although there are several types of renewable energy (hydro, geothermal, biomass, etc.), there are two that are considered the best:
It is often considered the best source of clean energy and falls into two categories: solar photovoltaic (harvesting sunlight) and solar thermal (using heat from the sun).
This type of energy can be captured by photovoltaic panels, heliostats or solar collectors.
The force of the wind is a powerful and efficient source of energy. Mills are the technology used to obtain it, and in Mexico the wind is one of the most important natural resources it has.
The only downside is that it’s intermittent, so it can’t be generated continuously.
The the importance of clean energy it’s clear and we need it if we want to have energy for the future in Mexico and in the rest of the world.
