Alternative jet fuels: biojet fuels' challenges and opportunities
The depletion of known petroleum reserves necessitates the development of new renewable
energy-based solutions as alternatives to petroleum-based transportation fuels. Increasing
energy consumption, limited fuel reserves, and climate change are major challenges of the
21st century. In 2016, the contribution of crude oil to the world's energy consumption was
32%, coal by 27%, and natural gas 21%. That is, approximately 80% of the world's energy
consumption was met by fossil fuels. In 2017, oil was the most significant contributor to …
