An overview of the principles and technology underlying the conversion of various renewable energy sources is given in this advanced training course. It also examines the problems that arise when different renewable energy sources are combined or integrated with grid that is connected with different loads. The future prospects of energy especially the advantage of renewable energy technology over conventional energy resources in terms of environmental impact, cost, reliability and efficiency will be examined, taking into account the sustainability and technical difficulties. There will also be discussion of some scientific standards, such as the wind-betz limit, standard grid cods, renewable energy conversion points, configuration of different renewable energy resources while integrating with grid. The construction, benefits, and drawbacks of every form of renewable energy generation will be covered.
