Review Questions

• Discuss how algae-based fuels compare to traditional biofuels in terms of production efficiency and environmental impact.
  • Algae-based fuels generally outperform traditional biofuels like corn-based ethanol in terms of production efficiency, yielding more oil per acre. Algae can be cultivated in conditions unsuitable for food crops and absorb carbon dioxide during growth, contributing positively to environmental sustainability. This efficiency makes algae a promising candidate for reducing reliance on fossil fuels while also helping to mitigate climate change.
• Evaluate the challenges that algae-based fuel production faces in achieving commercial viability compared to conventional fossil fuels.
  • Algae-based fuel production faces significant challenges in terms of high production costs, limited infrastructure for large-scale processing, and competition with established fossil fuel markets. Additionally, the technological hurdles related to efficient cultivation and extraction methods must be addressed. Overcoming these obstacles is essential for making algae-based fuels a commercially viable alternative to conventional fossil fuels.
• Analyze the potential role of algae-based fuels in addressing global energy needs and their implications for future energy policies.
  • Algae-based fuels hold substantial potential for addressing global energy needs due to their renewability and lower environmental impact compared to fossil fuels. As countries seek sustainable energy solutions amid climate change concerns, integrating algae-based fuels into energy policies could diversify energy sources, reduce greenhouse gas emissions, and promote energy security. This shift may also spur innovations in biotechnology and agriculture, further shaping future energy strategies.
