First of all, let’s take a look at what renewable energy means. Renewable energies are all those energy sources that are obtained from natural resources. These sources are: the sun, wind, water and plant or animal biomass.
Among the various renewable alternatives for generating electricity, solar energy and wind energy are the most popular options. In this sense, their role is decisive in reducing greenhouse gas emissions (GHG). The technologies for transforming these energy sources are solar panels and wind turbines, respectively. First of all, solar panels convert solar radiation into energy. The fact is that wind is equally generated by solar energy. This is due to the difference in atmospheric pressure caused by solar radiation. Basically, it is an energy based on movement. So, when the impulse of the wind turns the propellers of the generator, the turbine transforms the kinetic energy into direct current.
Without a doubt, sunlight and wind are sustainable, abundant and inexhaustible sources of energy.
