Reson 1 is the way power is generated. Due to the construction of generators, the default wave form is sinusoidal. Secondly, the frequency of sine wave is a single definite value while other wave forms are formed due to harmonics along with the fundamental sine wave and result in wastage of power in heating and thus reduce equipment life / rating. Hence sinusoidal wave is used for all electrical systems.
