Our daily energy needs are pushing us to consume more and more energy. But some of these resources are at the root of greenhouse gases and pollution. On the other hand, there are so-called renewable energies that are cleaner and more interesting.
Renewable energies: what are they?
Renewable energies, better known as “RE”, are energy sources that are built up and replenished as they are used. These renewable energies can complement or entirely replace other traditional energy sources. As a result, they have no negative impact on the ozone layer. Moreover, renewable energies are appreciated in both professional and domestic environments. These so-called renewable energies are highly valued for their safety performance. Moreover, they are highly appreciated for their lower cost.
Why opt for renewable energies?
Using renewable energy sources gives several advantages. First of all, renewable energies are based on an inexhaustible fuel unlike fossil fuels which are based on limited resource extraction techniques that consist in finding the resource where it is located. However, it should be noted that the exploiters of these natural resources are obliged to go further underground to find these resources, ultimately increasing the cost of these resources, but also their impact on the planet. This is in order to satisfy the needs of current world consumption, which is constantly increasing. Moreover, the energy bill of renewable energy is much better than that of fossil fuels. Moreover, renewable energy systems produce no or very little CO2 emissions, which differentiates them from fossil energy production based on a transformation stage that will have a great impact in terms of pollution.
The different types of renewable energy
There are 5 sources of renewable energy including solar energy which can be converted into heat, electricity or biomass via photovoltaic solar panels. On the other hand, there is wind energy which can be consumed or sold to a supplier; hydropower which can be transformed into electricity via dammed hydropower plants; geothermal energy which is not dependent on climatic conditions or seasons and biomass energy which is associated with conventional fuels to limit the greenhouse effect.
