Energy crises resulting from the depletion of petroleum resources, hikes in
the price of fossil fuel, and unpredictable climate change are some of the recent
concerns that have provoked serious research on alternative energy sources that would
be sustainable. This book chapter reviews how sustainable bioenergy production
through microbes using feedstocks can provide clean and green energy that can
consequently facilitate ecosystem restoration. Feedstocks are pivotal to this
biotechnological process. Microbes are also equally very vital. Therefore, changing
from fossil fuel to bioenergy resource options is essential. Energy transition can,
therefore, create emerging opportunities in bioenergy rendering and bioeconomy that
will result in the possible use of clean and green energy. In this regard, biofuels are a
straightforward substitute for fossil fuels. Renewable feedstocks are suitable
ingredients that sustainably produce biofuels using microbial-based bioconversion
processes. Microorganisms can massively secrete industrially important enzymes
capable of degrading long-chained biopolymers into short-chained monomeric sugars
and fermenting them into energy-dense biomolecules. Microbes play a crucial role in the sustainable generation of biofuels and bioenergy. Bioenergy research is, therefore,
crucial for a nation's economic stability and energy security. Additionally, reducing
greenhouse gas emissions while promoting the use of renewable energies and the
creation of livelihoods aids in the worldwide effort. Anthropogenic activities are highly
reduced, thereby enhancing ecosystem restoration.
