Review Questions

• How do renewable energy sources contribute to mitigating climate change?
  • Renewable energy sources significantly reduce greenhouse gas emissions compared to fossil fuels. By harnessing natural processes like sunlight, wind, and water flow, these energy systems produce electricity without emitting harmful pollutants. As a result, increasing the share of renewable energy in the global energy mix is crucial for limiting global warming and combating climate change effects.
• Evaluate the relationship between renewable energy adoption and resource depletion. How can renewable energy help conserve non-renewable resources?
  • Adopting renewable energy can greatly reduce the reliance on non-renewable resources like coal, oil, and natural gas. This shift helps conserve these finite resources, preventing depletion while also minimizing environmental degradation associated with extraction processes. By transitioning to renewables, society can ensure that essential resources are preserved for future generations while promoting sustainable resource management.
• Assess the impact of integrating renewable energy sources into a national energy strategy on sustainable development goals.
  • Integrating renewable energy into national energy strategies significantly advances sustainable development goals by promoting clean and affordable energy access while fostering economic growth. It supports environmental sustainability by reducing carbon emissions and protecting ecosystems. Additionally, it creates job opportunities and encourages technological innovation, helping countries achieve a balanced approach to social equity, economic prosperity, and environmental protection in their development efforts.
