Use of renewable energy in global energy mix and the challenges associated with their large-scale deployment.

Energy is the need for the future, and to fulfill this need, the use of renewable energy is a must. Furthermore, to counter the problem of global warming and climate change, the transition toward unconventional sources of energy is a requirement. Total global energy is majorly used in three sectors, namely, heating and cooling, transport, and electricity; however, the use and growth of renewable energy among these sectors are different. In this article, we discuss the potential of renewable energy in these sectors, the challenges associated with their large-scale deployment, and the possible solutions. [ABSTRACT FROM AUTHOR]
