Analysis of the energy and environmental situation and the use of biofuels worldwide

Resumen

The manuscript examines the historical interaction between economic and energy
development, highlighting its impact on the environment. The importance of energy
efficiency and the good use of natural resources are emphasized as solutions to
reduce the demand for energy worldwide and the emissions of polluting agents into
the atmosphere. An analysis is made and the decrease in fossil fuel reserves and the
increase in the generation of renewable energy, especially biofuels, are reflected.
The cases of Cuba, China, Japan, Mexico, Russia and Zambia are analyzed in terms of
energy matrices, dependence on fossil fuels and advances in renewable sources,
stressing the use of biofuels. The role of biofuels in the energy transition is
highlighted and the question is raised about their feasibility to face current
challenges.
