Abstract

Due to the limitations of fossil fuels, renewable energy has become the backbone of energy systems in many countries. The urgent need to meet growing energy demands while combating climate change has accelerated the global transition toward sustainable energy solutions. Renewable energy is derived from naturally replenishing sources such as solar, wind, and hydropower, whereas clean energy refers to energy sources that generate little or no greenhouse gas emissions. Despite its advantages, renewable energy faces several challenges, including uneven investment returns, policy uncertainties, and regulatory barriers. This review examines the global expansion of sustainable energy systems and explores their prospects by systematically analyzing recent scientific studies, industry reports, and policy documents.
