However, it needs to be emphasized that the distributed and intermittent sources of energy such as solar and wind cannot meet the base load demand very effectively. The nuclear energy source is concentrated, continuous and reliable and, therefore, can be complemented by solar and wind energy in meeting the overall demand of electricity with practically zero carbon foot-print. While the huge electricity demand from large cities and industrial complexes require uninterrupted and concentrated form of energy, there is an equally big demand of distributed energy in our rural areas. Energy planners are, therefore, combining these different patterns of energy requirement to achieve an optimised solution.
