What is renewable energy?

Renewable energy is usually opposite to fossil fuels (petrol, gas, carbon and uranium). Unlike the latter, they are inexhaustible, since they are constantly being replenished by nature. Renewable energy is generated by the sun, wind, terrestrial heat and even tides.

Another advantage renewable energy has over the burning of fossil fuels: it produces low amounts of carbon dioxide. Due to its low environmental impact, it is also sometimes called “green energy”.

During the last decade, renewable energy has experienced constant growth, thanks to an increase in production facilities: wind turbines, dams, photovoltaic panels, biomass, etc. Renewable energy’s share of the overall energy mix has thus been growing year after year in most areas.

The European Union, in particular, is on track to meet its goal of 20% renewable energy by 2020.

The challenges posed by renewable energy—mainly due to its intermittent nature—are increasingly being addressed through ongoing technical advancements. In the field of electric mobility alone, the ever-larger capacities of lithium-ion batteries and the increasing connectivity of vehicles are creating new possibilities. Bi-directional vehicle charging and stationary energy storage, for example, are making it possible for electric grids to harness as much renewable energy as possible and remain balanced.
