Entirely renewable energy-based electricity supply system (small scale & large scale)

Our future energy needs will be supplied by a combination of many different sources, ranging from small wind turbine to provide power for a single house to central power stations that provide power in very large scale fed into the national grid. Computer control systems will integrate the performance of all these systems to make sure that as much power as possible comes from environmentally friendlier sources. As alternative sources become more widely available, small scale systems meeting local needs may start to replace current large scale central power stations. The author is investigating the feasibility of an entirely renewable energy - based electricity supply system. The developed system find so many applications as it can be used as small scale power system for Remote Area Power Supply, wind energy/battery or solar energy/battery, as well as large scale for interconnection with national grid.
