Energy, sustainability, and engineering

There is concern over the cost of energy and its availability which has led to a need for the alternative energy resources. The global impacts of fossil fuel combustion are widely known in terms of the well-documented increase in CO 2 levels in the atmosphere. Since fossil fuel resources are the major current energy provider, it becomes important to consider if the such a production of energy is sustainable. On an another plane, Biomass is a unique energy alternative which helps in production of electricity, may also be converted into liquid fuels. An another alternative includes hydrogen economy, each of these alternatives are likely to be brought to use in the future of sustainable energy.
