Renewable energy is considered to be the main source of the baseload power. Some do believe this idea but the others do not. It is because the renewable energy has its own shortcomings which will not make it possible for these sources to meet the power needs. The theory is backed by the practical experience and it is done by modeling the energy provided by the renewable source. The practicality certainly shows that the consistent power is never provided by the renewable source which means that such power cannot be used at all. The idea is very widespread and is accepted by the experts all over the world. There is another group of experts that have the completely different idea. These theories are backed by the computer simulations which allow these experts to demonstrate that the renewable energy will certainly be used as the main source in the next few decades.
