Renewable Energies, Option of Future.

Abstract

The solar photovoltaic power, solar thermal power, wind power, biomass, biofuels, energy from waste power & small hydro power stations, etc. are part of the installations that allow the use of a huge number of different energies, called renewable energies, clean energies or new energies.

In fact the innovation resides fundamentally in technologies applied today to obtain energy, and the role assigned to these methods of power generation in the world of energy generation. This paper presents the development of this type of energies emphasizing its use to generate electricity.

The advantages and trade-offs will be analyzed, as well as short and mid term expectations, studying their incidence on the environment. Moreover, the main renewable energies will be described: Minihydroelectric power stations, solar thermal stations, solar photovoltaic stations, wind power stations biomass and urban waste power stations.
