Development of renewable energy

Without a doubt, the world is immersed in a historical change of its energy systems. Similarly, to the 19 th century, which meant the beginning of fossil energy sources, global energy markets are actually in a transitional period. The evolution of energy issues over the past decades provides a change of policies and regulations about this market. An energy market based mainly on traditional fossil energy sources, is now evaluating other alternatives sources, such as renewable energies.
