Solar energy is a clean and renewable resource that helps in transitioning away from fossil fuels and traditional power plants. It reduces greenhouse gas emissions and the dependence on finite energy sources. Solar energy also creates jobs, provides backup power during outages, and can be scaled up to large utility-scale power plants to meet the energy demands of entire communities.
