Several energy conservation programs were completed such as World's one of the largest dam, the Mangla Dam and several small dams and water reservoirs in West Pakistan while completing one dam in East Pakistan: Kaptai Dam. Plans toward harnessing energy from nuclear sources were authorized by President Ayub against the wishes of his own administration over the cost of nuclear power plants. Initially, there were two nuclear power plants to be established in the country: one was in Karachi and the second one in Dhaka. It was Dr. Abdus Salam who had personally approved the project in Karachi against the wishes of his own government, while the project in East was never materialized.
