Increasing the share of renewable energy in the national energy mix remains one of the major energy policy goals across many economies. This paper assesses the roles and potentials of renewable energy sources in less-developed economies while citing Nepal as an example. Renewable energy has a...

Motivated by the rise of the electricity tariffs applied on industrial customer and the frequent electricity cut offs recently experienced in Egypt, this paper assesses the economic feasibility of installing a stand alone wind energy technology by an industrial customer who seeks to reduce his...

The sustainability revolution is the defining challenge of our time to meet increasing needs in the energy−food−water nexus without compromising the ability of next generations. To feed the world, modern agriculture is primarily based on annual grain crops that replace native perennial plant...

The interest in algae based biofuels and chemicals has increased over the past few years because of their potential to reduce the dependence on petroleum-based fuels and chemicals. Algae is touted to be the most suitable and sustainable feedstock for producing green energy as the whole process...

Algae is a very promising source for renewable energy production since it can fix the greenhouse gas (CO2) by photosynthesis and does not compete with the production of food. Compared to microalgae, researches on biofuel production from macroalgae in both academia and industry are at infancy for...

Global outlook of biofuels turns out to be a full-fledged search focusing the viability and sustainability assets. The present day option for immediate and sustainable alternate fuels lies with algal biofuels. Algae are the most sustainable fuel resource in terms of food security and...

In an effort to reduce greenhouse gas emissions, renewable fuels (biofuels) are being developed and used in motor vehicles. The most common of these are bioethanol and biodiesel that are blended with petroleum based gasoline and diesel fuels at varying percentages. This provides some reduction...

Microalgae are getting more interests from industry and science communities. Applications of these small, unicellular microorganisms are countless: from fourth generation biofuels, through fish feed to pharmaceuticals. Ordinary methods of cultivation may be associated with many problems such as...

As a result of the search for energy stability and for the guarantee of national security after the oil crisis in the 70s, many developed and developing countries started studies and researches in order to develop alternative energy sources. Currently Brazil stands out in this field by...

Due to the energy crisis caused by the progressive depletion of fossil fuel sources, the search for alternative fuels from renewable sources is in growing demand. Therefore, the manufacturing of biodiesel from fish waste might help the environment as an alternative for the reduction of residues...
