Demonstrate best practices that South Africa, Zimbabwe and Rwanda may employ based on affordable and clean energy as the tenth Sustainable Development Goal

1. South Africa can invest in renewable energy sources such as solar, wind, and hydroelectric power. The country has abundant natural resources that can be harnessed for clean energy production.

2. Zimbabwe can adopt policies to promote energy efficiency in industries, buildings, and transportation. This can help reduce energy consumption and carbon emissions.

3. Rwanda can focus on expanding access to clean cooking solutions, such as biogas and improved cookstoves, to reduce reliance on traditional biomass fuels that contribute to indoor air pollution and deforestation.

4. All three countries can prioritize investment in grid infrastructure to improve energy access in rural areas, where communities often lack access to electricity and rely on polluting fuels for cooking and heating.

5. Collaboration between the public and private sectors, as well as with international organizations, can help accelerate the transition to affordable and clean energy. This can include partnerships for technology transfer, capacity building, and financial support.
