The major disadvantage of solar power (PV type only) is that it can not produce electricity during the night time and cloudy day time also. In India, this disadvantage can be overcome by installing pumped-storage hydroelectricity stations. Ultimate electricity requirement for river water pumping (excluding ground water pumping) is 570 billion kWh to pump one cubic meter of water for each square meter area by 125 m height on average for irrigating 140 million hectares of net sown area (42% of total land) for three crops in a year. This is achieved by utilising all the usable river waters by interlinking Indian rivers by envisaging coastal reservoirs. These river water pumping stations would also be envisaged with pumped-storage hydroelectricity features to generate electricity when necessary to stabilise the grid. Also, all existing and future hydro power stations can be expanded with additional pumped-storage hydroelectricity units to cater night time electricity consumption. Most of the ground water pumping power can be met directly by solar power during daytime. To achieve food security, India needs to achieve water security which is possible only by energy security for harnessing its water resources.
