Hydropower/Tidal/Waves Introduction Green Economy is a new model of economic development. RE can be defined as a free source of sustainable energy, such as wind or solar energy that produces no negative impacts during conversion process like the emission of hazardous substances. Each RE type is limited by the inherent characteristics of the energy source. Intermittency, variability, and maneuverability require effective management and control. RE resources Biomass Hydropower/Tidal/Waves Geothermal Wind Solar

RE Supply Chain The elements of RE supply chain include the physical, information, and financial flows. Technology is a key success factor to improve efficiency and to innovate the distribution network. In terms of demand, the commercialization of RE would be an important step to replace traditional fossil energy. The RE supply chain links the source of energy with other applications.

Renewable energy supply chain issues The performance of RE supply chain relates to its conversion efficiency which includes storage, distribution, efficiency and secondary applications efficiencies.

Cont. Renewable energy supply chain issues Conversion efficiency, considered as a key indicator for the use of a given energy resource, differs among the RE types Technology (Storage systems) Barriers to renewable energy development : Conversion cost Location selection Distribution network Commercialization barriers

Improving the renewable energy supply chain Involvement of the government and researchers (Incentives, rebates, tax compensation) Commercializing the use of renewable energy (affordable) Selecting storage technologies Realizing the value of renewable energies Distribution network (Smart grids , distributed energy networks )

Methodology The use of appropriate metrics for determining the goodness of an energy system is a critical phase of decision making. Mathematic Model, Multi-Criteria Analysis and Cost Analysis are used for the localization of plants and for the choice between a centralized or decentralized solution. Analysis Cost-Benefit, Net Present Value, Internal Rate of Return, Payback Period, Waste Valorization, CO2 Emissions Avoided are the indicators used for financial, social, economic and environmental results.

Some results of Models of supply Chain Analysis

Conclusion Improvement of distribution networks and the development of advanced storage technology are the recommended strategies for the further development of RE. The identified barriers are the conversion cost, location constraints, complex distribution networks and other considerable barriers. There is a limited use of quantitative methodologies for the correct choice of energy policies.
