The original source of energy for hydroelectricity is water.
The original source of energy for hydroelectricity is water.
The original source of the energy in any combustible plant material is from the sun.
The original source of energy for hydroelectricity is the gravitational potential energy of water stored in dams or reservoirs. When this water is released and flows through turbines, it generates mechanical energy, which is then converted into electrical energy.
Assuming you mean the source of energy, the original source of all energy for life on this planet is the sun.
The original source of energy in the biosphere is sunlight. Plants and other photosynthetic organisms convert sunlight into chemical energy through the process of photosynthesis, which is then used by living organisms as a source of energy.
