Final answer:
The Srisailam power station uses hydroelectric power as its major source of energy for electricity production, by converting the potential energy of dam-stored water into electric current.
Step-by-step explanation:
The major source of energy for the production of electricity at the Srisailam power station, located along the Krishna River in India, is hydroelectric power. The facility harnesses the potential energy stored in the water of the dam, which is then released and converted to kinetic energy to turn turbines. This mechanical energy is used to generate electric current in a generator, contributing significantly to the electricity grid. While fossil fuels remain a major source for electric power generation globally, hydropower is a key renewable energy source, especially in regions like New Zealand where it meets a large portion of electricity demand.
