Climate change and its impacts present significant challenges to global sustainability, with businesses often contributing to the rise of greenhouse gas emissions through reliance on finite fossil fuel resources. As energy demands increase due to societal and economic development, renewable energy (RE) technologies offer a viable solution to mitigate climate change and meet global energy needs. This study explores various RE technologies, bioenergy, solar energy, geothermal energy, hydropower, and wind energy, and their roles in reducing greenhouse gas emissions and promoting sustainable energy practices. The findings highlight the advantages of renewable energy, including reduced carbon footprints, cost efficiency, and energy security. The study also addresses the challenges posed by climate change to renewable energy resources, emphasizing the need for robust policy interventions and investments in climate-resilient infrastructure. Adoption of RE technologies is essential for transitioning to a sustainable energy future and mitigating the adverse effects of climate change.
