Renewable energy plays a crucial role in combating climate change by providing a cleaner alternative to fossil fuels, which are the primary source of greenhouse gas emissions. Sources like solar, wind, hydroelectric, and geothermal energy produce little to no carbon emissions, helping to reduce the overall carbon footprint. By transitioning to renewable energy, we can lower the concentration of carbon dioxide and other harmful pollutants in the atmosphere, mitigating global warming. Additionally, renewable energy promotes energy efficiency and sustainability, helping to conserve natural resources and create long-term solutions for energy needs. As part of a broader strategy, renewables are key to achieving global climate goals and ensuring a healthier planet.
