A hydroelectric power facility (see figure) converts the gravitational potential energy of water behind a dam to electric energy. The gravitational potential energy I calculated is 2.08*1016 a.  A 9 megaton fusion bomb (which is around 1000 times bigger than the WWII-era nuclear bombs) contains 3.8 × 1016 J of energy. What fraction of this energy is contained in the potential energy of the entire lake?
