Global energy demand continues to show exponential trends as the population and needs in developing societies increase and at the same time energy dependence on some countries creates a domino of energy insecurity in those that have not already invested in the RES sector. The key question that has been strongly raised in recent years in the global community is how an energy policy friendly to the environment can be developed with energy sufficiency and affordable prices. RES, with their wide spread throughout the planet, offer themselves to be used to meet the needs of modern people, contributing decisively to the fight against climate change.

RES can lead our planet’s societies and economies to sustainable development in the fastest and safest way. A big challenge is the utilization of RES in power generation with a large penetration in the electric grids, where they enter dynamically with new, innovative technologies. RES are invading the electrical networks as a domestic source with the main characteristics being the high reliability of the equipment and the low cost of operation and maintenance.
