Demonstrate the best practices that each country may employ based on affordable and clean energy as the tenth Sustainable Development Goal.

1. Promoting the use of renewable energy sources such as solar, wind, hydroelectric, and geothermal power can help reduce reliance on fossil fuels and decrease greenhouse gas emissions. Countries can invest in infrastructure to support the development and use of these renewable energy sources.

2. Implementing energy efficiency measures in buildings, transportation, and industries can help reduce energy consumption and lower costs. This can be achieved through the adoption of energy-efficient technologies, building codes, and regulations.

3. Encouraging the use of clean cooking technologies such as improved cookstoves and biogas can help reduce indoor air pollution and improve health outcomes. Countries can provide subsidies or financial incentives to promote the adoption of these technologies.

4. Promoting sustainable transportation options such as public transportation, biking, and walking can help reduce emissions from the transportation sector. Countries can invest in infrastructure for these modes of transportation and implement policies to discourage car use.

5. Engaging with stakeholders including government agencies, businesses, non-governmental organizations, and communities can help promote awareness and collaboration on affordable and clean energy initiatives. Countries can establish partnerships and platforms to facilitate dialogue and knowledge-sharing on sustainable energy practices.

Overall, a combination of policy interventions, technological innovations, and community involvement is needed to achieve affordable and clean energy for all. By adopting these best practices, countries can contribute to the achievement of the tenth Sustainable Development Goal and create a more sustainable future for all.
