What are the main types of renewable energy sources, and how do they contribute to reducing greenhouse gas emissions, mitigating climate change, and transitioning to a low-carbon economy?

Renewable energy sources such as solar, wind, hydroelectric, biomass, and geothermal power harness natural energy flows or resources to generate electricity or heat without depleting finite fossil fuel reserves or emitting greenhouse gases. They offer sustainable alternatives to conventional energy sources, reducing dependence on fossil fuels, promoting energy security, and mitigating climate change. Renewable energy technologies continue to advance in efficiency, affordability, and scalability, driving the transition to a cleaner, more sustainable energy future.
