A different review on smart grid concepts was described by Di Santo et al., who defined smart grid as вЂњa generation, transmission, and distribution system set with a two-way communication system controlled by the grid operatorвЂќ. вЂњrenewable energy sourcesвЂќ often referred to as distributed energy resources (DERs), while вЂњsmart-gridsвЂќ refers to the whole electrical energy distribution networks from electricity generation to its transmission and storage with the capability to react to dynamic changes on energy distribution and load regulation. Smart grids are computer controlled micro-grids. Renewable energy and micro-grid had emerged from the development of new grid technology referred as smart grids. Modern renewable energy education includes a study of the technology, resources, systems design, economics, industry structure and policies in an integrated package. Renewable energy education is a relatively new field and previously it formed a minor part of traditional engineering courses. Burning fossil fuels causes pollutant emissions and greenhouse gases contributing to global warming. Even if fossil fuels supplies are unlimited, it is better to use renewable energy sources as they are clean technologies.

Renewable energy technologies revolve these sources into utilizable forms of energy not only electricity but also heat, chemicals, or mechanical power. The well-known RE sources are solar, wind, hydropower, biomass and geothermal. REsources are offering the suitable solution for such situations, as have been the answer for remote, isolated dwelling electrification, substituting or integrated with diesel fueled generators.

Compared to fossil fuel energy generation and nuclear power stations, REis considered the safest benign energy generation sources. Rapid increases in energy demand and energy deficiency are two contradicting facts that face developing countries at the present and expectedly in the future. REis seen by many as part of the appropriate response to these concerns and some national governments have put programs in place to support the wider use of sustainable energy systems. Renewable energy ( RE) industry is growing rapidly with rising concerns about oil depletion and climate change.
