A smart grid is an electricity system that uses digital communications technology to detect, respond to, and take appropriate action in response to changes in demand and a variety of other problems. The secret to effective utilization of distributed energy resources is smart grid technology. Opportunities for renewable energy systems to address electricity generation appear to be growing, especially in light of the importance of climate change, the rising cost of petroleum products, and the falling cost of renewable energy power systems. However, an effective energy management strategy of system must be addressed in order to achieve commercialization and widespread use. Electric power networks have recently benefited from the effective application of the smart grid idea. This research work examines the overview of smart grid technology as a renewable energy source. The concept of a smart grid as well as the advantages and disadvantages of a smart grid renewable energy. The success of promoting renewable energy is significantly influenced by pricing. As a result, it is crucial to evaluate the distinctive qualities connected with alternative sources of renewable energy in order to get insight into the pricing of renewable energy. A survey of recent work in renewable smart grid systems shows the exciting future potential of such research traits. Both policymakers and those who create and use renewable energy systems would benefit from this.

Fossil fuels (crude oil, natural gas, coal, and lignite) have historically been Nigeria's main energy source. Unfortunately, all of these factors combined with additional factors—including an increase in industrial activity, an increase in national population, and worldwide climate changes—could no longer support us. As a result, our houses and businesses now face significant energy demands. There must be a different source of energy that is not exhaustible in order to keep up with the rush. Given that Nigeria is a resource-rich nation, the article aims to provide an overview of renewable energy, list its benefits and drawbacks, and make recommendations for how to use it more effectively in order to compete favorably with other nations.
