Review Questions

• How does energy efficiency contribute to reducing greenhouse gas emissions?
  • Energy efficiency contributes to reducing greenhouse gas emissions by lowering the amount of energy required for various processes while maintaining the same output. When less energy is used, particularly from fossil fuel sources, there are fewer emissions produced. This reduction in energy demand means that power plants can generate less electricity, resulting in decreased emissions of carbon dioxide and other harmful pollutants that contribute to climate change.
• Discuss the relationship between energy efficiency measures and economic growth.
  • Energy efficiency measures can stimulate economic growth by lowering operational costs for businesses and households. When energy bills are reduced through efficient practices or technologies, these savings can be redirected towards investment in other areas, such as hiring employees or expanding operations. Additionally, sectors focused on developing and implementing energy-efficient technologies can create new jobs and foster innovation, contributing positively to the economy.
• Evaluate the effectiveness of government policies in promoting energy efficiency and their impact on sustainable development.
  • Government policies aimed at promoting energy efficiency have proven effective in driving widespread adoption of efficient technologies and practices. By providing incentives such as tax credits, rebates, and subsidies for energy-efficient upgrades, governments encourage consumers and businesses to invest in sustainable solutions. This shift not only reduces overall energy consumption but also advances sustainable development by mitigating environmental impacts, supporting clean technology innovations, and enhancing resilience against climate change challenges.
