DEVELOPMENT OF RENEWABLE ENERGIES IN ALGERIA FOR A STABILITY

This paper presents the status of the various renewable energy technologies, the strategy for their development, the progress made and the difficulties encountered. Nine categories of Renewable Energy in the world are discussed: (physical biomass), biofuels and biogas (and renewable waste), - hydroelectricity, - wind power, - solar photovoltaic (PV) power, - solar thermal power, - concentrated solar power (or thermodynamic), - geothermal power, - heat pump power, - "marine" power. The level of advancement and competitiveness of Renewable Energies is very differentiated according to the technologies, as well as their cost, which also varies greatly according to the resource, local potential and geography. There are technical, financial, political, energy strategy and climate change considerations to take into account. The purpose of this article is only to shed light on the current position and future of Renewable Energies. It is only an element of reflections on energy strategies, whether they are related to energy production or energy demand management (uses, lifestyles and energy savings). These problems have been the subject of many other articles of the Encyclopedia of Sustainable Development recalled in the attached bibliography.
