Artificial neural networks (ANN) are preferred over some other machine learning (ML) techniques due to their extension potential. The requirement for using ML approaches inside the renewable energy market would rise significantly in the upcoming decades, due to the huge market for graduate institutions in research, mathematics, and technology connected to machine learning. Collection of data, administration, and protection are predicted to play critical roles in the effective deployment of ML techniques that may be distributed among the main players in the renewable energy industry, hence fostering the creation of large smart energy schemes. The integration of new techniques for generating accurate data, as well as other pieces of knowledge, will improve the communication of data among ML and networks. Both supervised and unsupervised learning are likely to play important roles in the renewable energy industry, however, this will hinge on the development of certain other significant topics in machine learning, like big data analytics (BDA). Because the renewable energy business is dependent on weather, forecasting is an essential aspect of renewables. Machine learning algorithms aid in the precise prediction of renewables.
