This paper is aimed at preliminary study on the contribution of solar power within 15 years, since generation of electricity represents the highest percent of the fossil fuel consumption. The significant increase of electricity demand in Saudi Arabia means that power generation will expand and that will lead to increased consumption of fossil fuels. This rapid increase of the conventional generation...
Renewable energies cloud reduces the GHG emissions. However, renewable energies have “price gap” of electricity between renewable energy and grid power. Thus, government policies are important to lead to “grid parity.” The renewable energy policies in Japan and Europe were analyzed. As the results, I found that the policies depend on the “price gap” between renewable energy and grid power. I propose...
This paper deals with an analysis of hydrogen production system using the photolysis process. Solar energy potential in Algeria is highlighted to show its direct hydrogen production possibility. Experimental tests for hydrogen production using solar cells waste were conducted at the CDER (Center of Development of Renewable Energy) at Bouzareah - Algiers. Hydrogen molar production is determined by...
The paper gives one solution concerning the modality of power supply for anti-hail stations consumers. Because the anti-hail stations are situated in isolates areas, without electrical network access, the solution consist in the supply with electric energy from photovoltaic panels and accumulator batteries. There are also shown aspects regarding to energy efficiency of photovoltaic system, particularly...
The optimal integration of future grid-connected PV systems will become essential as developments in solar cell technology lead to cheaper PV devices. Moreover as direct financial incentives and subsidies to PV systems are gradually phased out; cheaper PV devices, developed at the likely expense of life expectancy and efficiency, may prevail. This paper presents a model that can be applied to optimize...
There is an increasing acceptance for the use of renewable energy sources to achieve a sustainable power supply. In our contribution we present a vision of new energy supply structures and a cluster of projects supported by the European Commission which address the integration of renewable energy sources (RES) and distributed generation (DG) into the electricity grid.
