How Solar Energy Supports the UN Sustainable Development Goals (SDGs)

The United Nations Sustainable Development Goals (SDGs) are a blueprint for building a better future that is inclusive, equitable, and environmentally responsible. Many of these goals rely heavily on solar energy, which is one of the fastest-growing renewable energy sources. In addition to cutting carbon emissions.

1. SDG 7: Affordable and Clean Energy

• Solar power directly addresses SDG 7, which aims to ensure access to affordable, reliable, sustainable, and modern energy for all.
• Solar technology enables decentralized energy solutions in remote and rural areas where grid access is limited.
• The cost of solar has dropped by more than 80% in the last decade, making clean energy more accessible than ever.

Example: Off-grid solar kits in African villages have enabled households to replace kerosene lamps, cutting costs and improving indoor air quality.

2. SDG 13: Climate Action

• Climate change is one of the greatest threats to humanity, and SDG 13 focuses on urgent action to combat it.
• Solar power generates electricity without emitting greenhouse gases.
• Replacing coal and fossil fuel plants with solar installations significantly reduces a country’s carbon footprint.

Impact: Every megawatt-hour of solar electricity can prevent roughly 0.7 metric tons of CO₂ emissions.

3. SDG 8: Decent Work and Economic Growth

• The solar industry is a powerful driver of green jobs, supporting SDG 8.
• Manufacturing, installation, maintenance, and research in solar create millions of employment opportunities worldwide.
• These jobs often require skill development, promoting workforce growth and training.

Example: The International Renewable Energy Agency (IRENA) estimates that solar PV jobs surpassed 4.9 million globally in 2022.

4. SDG 3: Good Health and Well-being

• Switching to solar can improve public health—aligning with SDG 3.
• Replacing fossil fuels reduces air pollution, lowering rates of respiratory and cardiovascular diseases.
• Access to reliable solar power supports better healthcare delivery in clinics and hospitals.

Example: Solar-powered vaccine refrigerators have saved lives in rural healthcare facilities.

5. SDG 9: Industry, Innovation, and Infrastructure

• Solar contributes to SDG 9 by encouraging innovation in energy technology and infrastructure.
• Advances in solar PV efficiency, storage solutions, and smart grids are transforming energy systems.
• Large-scale solar farms and rooftop installations strengthen resilient infrastructure.

6. SDG 11: Sustainable Cities and Communities

• Solar supports SDG 11 by enabling greener, more resilient cities.
• Solar rooftops, community solar projects, and solar-powered public transport reduce urban emissions.
• Energy independence makes communities less vulnerable to energy price fluctuations.

7. SDG 15: Life on Land

• When designed responsibly, solar farms can also enhance biodiversity—contributing to SDG 15.
• Pollinator-friendly vegetation around solar panels supports bees and other wildlife.
• Combining solar with agriculture (agrivoltaics) helps conserve land and water resources.
