Biofuels versus climate change: Exploring potentials and challenges in the energy transition

Abstract: In a scenario characterized by the constant rise of global temperatures and extreme climatic events, the need for sustainable energy alternatives is urgent. Biofuels, derived from biomass, emerge as a promising option to reduce greenhouse gas emissions and combat global warming. Biofuels are categorized into different generations, each with specific characteristics in terms of raw materials and production technology. While the first generation uses food sources such as corn and sugarcane, the second and third generations focus on non-food raw materials, like agricultural residues and algae, offering a more favorable carbon balance and lesser environmental impact. Advances in the fourth generation, involving techniques like artificial photosynthesis, represent a significant leap in energy efficiency and sustainability. The sustainability of production, responsible agricultural practices, and distribution infrastructure are crucial aspects for the effective integration of biofuels into the energy matrix. This study recommends integrated policies, investment in research and development, promotion of second and third generation biofuels, public awareness, and sustainable production practices. Investing in infrastructure and monitoring and evaluation systems is also essential. The transition to biofuels requires a holistic approach, balancing energy needs with environmental protection, and considering social and economic implications. Successful implementation of biofuels can signify a significant step towards a cleaner and more sustainable energy future.
