#LearnSustainability: Energy mixDo you know what the energy mix is? We explain the concept and its meaning in this infographic
A primary energy source is any form of energy available in nature before being converted or transformed. There are different types of primary energy: those coming from fossil fuels (mainly coal, oil and natural gas), which take thousands of years to regenerate and are therefore exhaustible; and renewable energy, such as water, sun, wind, biomass and geothermal, which are inexhaustible and are almost always available.
In 2015, oil, gas and coal were the primary energies most used worldwide, although renewable, with hydropower on top, has been increasingly used and implemented.
