Ethanol production from cellulosic sources such as switchgrass (Panicum virgatum L.) requires the use of natural resources, fossil fuels, electricity, and human-derived goods and services. We used emergy accounting to integrate the ultimate amount of environmental, fossil fuel, and human-derived...

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...

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...

One of the most important dilemmas of the modern world is to supply enough energy with minimal environmental impact. On this demand bioenergy from renewable biofuels is of growing public and private interest.

Nigeria is among the World’s 10 most important exporters of petroleum, but has several difficulties in its domestic energy situation. Power outages are frequent in the cities and 49% of the population has no access to electricity at all. The use of fossil fuels and firewood causes many...

Energy crops constitute significant potential for meeting the future energy need worldwide. In addition, agricultural lands offer an alternative to the agriculture which is referred to as energy farming. The studies on energy crops in biofuel production show that they are quite an economical and...

Crops for biofuels squanders cropland, water, and energy resources vital for food production needed for people.

Los biocombustibles han experimentado una fuerte expansión gracias a los incentivos otorgados por los poderes públicos y a algunas ventajas como la capacidad para reducir la dependencia energética exterior, la mayor creación de empleos, especialmente en zonas rurales, o el menor impacto...
