Review Questions

• How does solar energy contribute to reducing greenhouse gas emissions compared to traditional fossil fuels?
  • Solar energy significantly reduces greenhouse gas emissions because it harnesses a clean and renewable resource: sunlight. Unlike fossil fuels, which release carbon dioxide and other harmful pollutants when burned for energy, solar power generates electricity without producing these emissions. This shift to solar can help mitigate climate change by lowering the overall carbon footprint of energy consumption.
• Discuss the economic implications of transitioning to solar energy in terms of job creation and investment opportunities.
  • Transitioning to solar energy has substantial economic implications, including the creation of jobs in manufacturing, installation, and maintenance of solar systems. The growing demand for renewable energy sources has led to increased investment opportunities in solar technology and infrastructure development. Additionally, as solar power becomes more widely adopted, it can stimulate local economies by reducing energy costs and enhancing energy independence.
• Evaluate the challenges associated with solar energy deployment and how they can be addressed to enhance sustainability.
  • Challenges associated with solar energy deployment include intermittency issues due to varying sunlight availability, high initial installation costs, and the need for efficient storage solutions. To enhance sustainability, these challenges can be addressed through technological advancements in battery storage systems that allow excess energy to be stored for later use. Additionally, supportive government policies and incentives can help reduce costs and promote widespread adoption of solar technologies.
